    DECIDED: February 1, 2007
    ________________________
    Before NEWMAN, GAJARSA, and PROST, Circuit Judges.
    Opinion for the court filed by Circuit Judge GAJARSA.        Dissenting opinion filed by
    Circuit Judge NEWMAN.
    GAJARSA, Circuit Judge.
    This is an interlocutory appeal by Cordis Corp. from a decision of the U.S. District
    Court for the Western District of Oklahoma assuming supplemental subject matter
    jurisdiction pursuant to 
    28 U.S.C. § 1367
     over the foreign patent infringement claims of
    Jan K. Voda, M.D. (“Voda”).     The district court established jurisdiction over Voda’s
    original claims of U.S. patent infringement pursuant to § 1338. In a subsequent order,
    the district court granted Voda leave to amend his complaint to add infringement claims
    based on foreign patents. Voda’s amended complaint alleged infringement taking place
    outside the United States in violation of patents issued by various foreign countries.
    The district court found subject matter jurisdiction over the foreign patent claims
    pursuant to the supplemental jurisdiction statute § 1367. Voda v. Cordis Corp., No. 03-
    1512, slip op. at 2 (W.D. Okla. Aug. 2, 2004). The district court certified its order for
    interlocutory review pursuant to § 1292(b). We agreed that the interlocutory appeal
    “involve[s] a controlling question of law to which there is a substantial difference of
    opinion and for which an immediate appeal may materially advance the ultimate
    termination of the litigation” and thus, granted Voda’s petition for interlocutory appeal of
    “whether the district court has supplemental subject matter jurisdiction over Dr. Voda's
    five foreign patents.” Voda v. Cordis Corp., 122 Fed. App’x 515 (Fed. Cir. 2005). This
    court has jurisdiction pursuant to § 1292(b) and (c).
    In Stein Associates, Inc. v. Heat & Control, Inc., 
    748 F.2d 653
    , 658 (Fed. Cir.
    1984), this court held that U.S. district courts had no discretionary power to enjoin a
    party from enforcing a foreign patent before a foreign tribunal. We stated unequivocally
    that “the issues are not the same, one action involving United States patents and the
    other involving British patents” and that “[o]nly a British court, applying British law, can
    determine validity and infringement of British patents.” In this case, we are presented
    with a different issue but one that raises similar concerns: whether a district court may
    exercise supplemental jurisdiction pursuant to 
    28 U.S.C. § 1367
     over infringement
    claims based on foreign patents. For the reasons discussed below, we conclude that
    the district court erred in granting leave to amend based on § 1367. Accordingly, we
    vacate the order of the district court granting leave to amend and remand for further
    proceedings consistent with this opinion.

    I. BACKGROUND
    The plaintiff-appellee Voda is a resident of Oklahoma City, Oklahoma.            The
    defendant-appellant Cordis is a U.S.-based entity incorporated in Florida. None of the
    several foreign Cordis affiliates is a party to the present action, and we note that they
    appear to be separate legal entities.1 These foreign affiliates have not been joined to
    this action.2 To prevent confusion, we refer to the defendant-appellant as “Cordis U.S.”
    The patents at issue relate generally to guiding catheters for use in interventional
    cardiology. The details of the technology are not essential here. Voda’s U.S. patents
    stem from a common continuation-in-part (“CIP”) application filed in October 1992,
    which provides the written description common to the three U.S. patents at issue in this
    case: U.S. Patent Nos. 5,445,625 (the ’625 patent), 6,083,213 (the ’213 patent), and
    6,475,195 (the ’195 patent).      The foreign patents issued from a common Patent
    Cooperation Treaty (“PCT”) application. The PCT application designated the European
    Patent Office (“EPO”) and Canada as recipients.           Voda’s EPO patent application
    eventually generated European Pat. No. 0 568 624, British Pat. No. GB 568 624,
    French Pat. No. FR568624, and German Pat. No. DE 69 23 20 95.                     The PCT
    application also ultimately led to the issuance of Canadian Pat. No. CA 2,100,785.
    Voda sued Cordis U.S. in the United States District Court for the Western District
    of Oklahoma alleging infringement of his three U.S. patents: claims 1-2 and 5-7 of the
    1
    For example, in addition to Cordis (U.S.), there are Cordis U.K., Ltd.,
    Cordis S.A. (France), Cordis G.m.b.H. (Germany), Cordis S.p.A. (Italy), and Cordis
    Benelux (Netherlands). All of the Cordis companies, both U.S. and foreign, are
    members of the Johnson & Johnson family of companies.
    2
    Therefore, to the extent that the dissent suggests that the district court has
    personal jurisdiction of the foreign Cordis entities, it is incorrect. See Dissent 1, 10, 19.
    05-1238
    3
    ’625 patent, claims 1-5 of the ’213 patent, and claims 1-6 of the ’195 patent. Cordis
    U.S. answered by asserting noninfringement and invalidity of the U.S. patents.
    Voda then moved to amend his complaint to add claims of infringement of the
    European, British, Canadian, French, and German foreign patents. Voda’s amended
    complaint alleges that “Cordis [U.S.] has commenced and continues acts of making,
    selling, offering for sale and selling at least the XB guiding catheter, which is covered by
    [the several foreign patents] without Dr. Voda’s authority.          Such acts constitute
    infringement, under corresponding foreign law of [these several foreign patents].”
    Cordis U.S. has admitted that “the XB catheters have been sold domestically and
    internationally since 1994.    The XB catheters were manufactured in Miami Lakes,
    Florida from 1993 to 2001 and have been manufactured in Juarez, Mexico since 2001.”
    Voda’s amended complaint asks for damages, fees, and “such other and further relief
    as this Court deems just and proper.” We resolve the jurisdictional issue based upon
    those allegations, accepting them to be true.
    Cordis U.S. opposed Voda’s attempt to amend its complaint to add foreign patent
    infringement claims on the basis that the district court lacked subject matter jurisdiction
    over such claims. The parties briefed the court regarding its jurisdiction over foreign
    patent infringement claims under 
    28 U.S.C. § 1367
    (a) and its discretion to exercise
    supplemental jurisdiction under § 1367(c).       In a three-page order, the district court
    analyzed two circuit court cases discussing supplemental jurisdiction over patent claims,
    Mars, Inc. v. Kabushiki-Kaisha Nippon Conlux, 
    24 F.3d 1368
     (Fed. Cir. 1994) (finding no
    jurisdiction), and Ortman v. Stanray, 
    371 F.2d 154
     (7th Cir. 1967) (affirming district
    court’s denial of a motion to dismiss foreign patent infringement claims). The district
    05-1238
    4
    court determined that “[t]he allegations in the [proposed] amended complaint
    demonstrate that this case is more akin to Ortman than to Mars” and thus, that “it would
    have supplemental jurisdiction over the foreign patent[] claim[s].” Voda v. Cordis, No.
    CIV-03-1512-L, slip op. at 2 (August 2, 2004). Therefore, the district court granted
    Voda’s motion to file his amended complaint. 
    Id.
    Cordis U.S. appeals, and in light of this appeal, the proceedings with respect to
    the foreign patent infringement claims have been stayed.3 The record indicates that an
    answer to the amended complaint has not been filed and that discovery has not been
    taken on the foreign claims. While the record therefore does not establish the defenses
    Cordis U.S. would raise, Cordis U.S. represents on appeal that it would raise invalidity
    of the foreign patents as a defense.
    A proper exercise of subject matter jurisdiction pursuant to § 1367 requires both
    the presence of jurisdiction under subsection (a) and an appropriate decision to
    exercise that jurisdiction under subsection (c). For the reasons discussed below, we
    conclude that the district court erred under subsection (c).
    II. STANDARD OF REVIEW
    The existence of supplemental jurisdiction over foreign patent claims based on
    claims of U.S. patent infringement is a question unique to U.S. patent law, and thus, we
    apply the law of our circuit rather than that of the regional circuit. Mars, 
    24 F.3d at 1371
    (“The issue whether the district court had jurisdiction to hear Mars’ claim of Japanese
    patent infringement is of importance to the development of the patent law and is clearly
    3
    It appears that the district court conducted a jury trial on Voda’s U.S.
    patent infringement claims, and that the jury found in favor of Voda on May 25, 2006.
    (Jury Verdict, May 25, 2006.) None of the parties or amicus curiae informed the court of
    this event, and we do not consider it necessary to our ultimate holding.

    a matter that falls within the exclusive subject matter responsibility of this court.”

    Corp., 
    384 F.3d 1326
    , 1330 (Fed. Cir. 2004) (applying Federal Circuit law because we
    “apply the law of the regional circuit . . . unless the issue pertains to or is unique to
    patent law, in which case we will apply our own law to both substantive and procedural
    issues intimately involved in the substance of enforcement of the patent right” (quotation
    marks omitted)); cf. Unitherm Food Sys. v. Swift-Eckrich, Inc., 
    126 S. Ct. 980
    , 984
    (2006) (recognizing that Federal Circuit is bound to apply procedural law of regional
    circuit in case where issue did not pertain uniquely to patent law).
    We have noted that “[t]his Court . . . reviews jurisdiction, a question of law, de
    novo.” Dehne v. United States, 
    970 F.2d 890
    , 892 (Fed. Cir. 1992) (citation omitted);
    see also Elder v. Holloway, 
    510 U.S. 510
    , 516 (1994) (“[Q]uestion[s] of law . . . must be
    resolved de novo on appeal.”). “A party seeking the exercise of jurisdiction in its favor
    bears the burden of establishing that such jurisdiction exists.” Mars, 
    24 F.3d at
    1372
    (citing KVOS, Inc. v. Associated Press, 
    299 U.S. 269
    , 278 (1936)); cf. DaimlerChrysler
    Corp. v. Cuno, 
    126 S. Ct. 1854
    , 1861 (2006) (“[P]arties . . . asserting federal
    jurisdiction[] carry the burden of establishing their standing under Article III.”). Here,
    Voda must carry this burden.
    III. DISCUSSION
    The Supreme Court has stated many times that the “district courts of the United
    States . . . are ‘courts of limited jurisdiction. They possess only that power authorized
    by Constitution and statute.’” Exxon Mobil Corp. v. Allapattah Servs., 
    545 U.S. 546
    , ---,
    
    125 S. Ct. 2611
    , 2616-17 (2005) (quoting Kokkonen v. Guardian Life Ins. Co. of Am.,
    05-1238
    6
    
    511 U.S. 375
    , 377 (1994)). In addition, “district courts may be obligated not to decide
    state law claims (or to stay their adjudication) where one of the abstention doctrines
    articulated by [the Supreme] Court applies.” City of Chicago v. Int’l Coll. of Surgeons,
    
    522 U.S. 156
    , 174 (1997).
    In this case, the parties do not dispute that the Constitution may authorize district
    courts to hear infringement claims based on foreign patents. See U.S. Const. art. III,
    § 2 (“[J]udicial Power shall extend . . . to Controversies . . . between a State, or the
    Citizens thereof, and foreign States, Citizens or Subjects.”). Rather, the critical disputed
    issue is whether there is any statutory basis for such subject matter jurisdiction.4
    A.     Asserted Statutory Basis
    Voda asserts that the district court has supplemental jurisdiction under 
    28 U.S.C. § 1367
     of his foreign patent infringement claims.5 The Supreme Court has noted that
    the statute “is a broad grant of supplemental jurisdiction over other claims within the
    same case or controversy, as long as the action is one in which the district courts would
    have original jurisdiction.” Exxon, 
    125 S. Ct. at 2620
    . “The presence of other claims in
    4
    The dissent broadly states that no court has held “that it had no power or
    authority to receive the foreign issue.” Dissent 6. Yet, the first case cited by the dissent
    to support this broad proposition, written by the dissenting author, held that there was
    no jurisdiction and alternatively, affirmed the dismissal based on forum non conveniens.
    See Bonzel v. Pfizer, Inc., 
    439 F.3d 1358
    , 1362-65 (Fed. Cir. 2006); see also Mars, 
    24 F.3d at 1373-75
     (holding that no federal question or supplemental jurisdiction existed).
    5
    Voda has asserted no other statutory basis for subject matter jurisdiction.
    Therefore, the dissent’s assertion that “judicial authority to determine and apply foreign
    law does not require that the foreign issue is supplemental to a domestic issue,” Dissent
    8, is irrelevant in this case. Similarly, the cases cited by the dissent that rely on federal
    question jurisdiction or diversity jurisdiction are inapposite. See, e.g., Uebersee Finanz-
    Korporation, A.G. v. McGrath, 
    343 U.S. 205
    , 206 (1952) (claim under U.S. law, Trading
    with the Enemy Act of 1917); Cambridge Literary Properties, Ltd. v. W. Goebel
    Porzellanfabrik G.m.b.H. & Co. Kg., 
    295 F.3d 59
    , 61-63 (1st Cir. 2002) (claim under
    U.S. copyright law); Curley v. AMR Corp., 
    153 F.3d 5
    , 12 (2d Cir. 1998) (diversity
    jurisdiction); see also Dissent 3-5.
    05-1238
    7
    the complaint, over which the district court may lack original jurisdiction, is of no
    moment.” Id.; cf. Marshall v. Marshall, 
    126 S. Ct. 1735
    , 1749 (2006) (stating in diversity
    context that jurisdiction “is determined by the law of the court’s creation and cannot be
    defeated by the extraterritorial operation of a [state] statute . . . , even though it created
    the right of action” (quotation marks and citations omitted)).
    The Supreme Court has also noted that § 1367 both “authorize[s] the district
    courts to exercise supplemental jurisdiction” and “confirms the discretionary nature of
    supplemental jurisdiction.” Chicago, 
    522 U.S. at 172-73
    . Therefore, to allow Voda to
    amend his complaint to add infringement claims based on foreign patents using § 1367
    supplemental jurisdiction, we must evaluate (1) whether § 1367(a) authorizes such
    supplemental jurisdiction and (2) whether the district court’s exercise of such
    supplemental jurisdiction was within its § 1367(c) discretion.
    1.      Authorization
    Section 1367(a) provides the statutory authority for district courts to exercise
    supplemental jurisdiction over certain claims outside their original jurisdiction.
    Except as provided in subsections (b) and (c) or as expressly
    provided otherwise by Federal statute, in any civil action of which
    the district courts have original jurisdiction, the district courts shall
    have supplemental jurisdiction over all other claims that are so
    related to claims in the action within such original jurisdiction that
    they form part of the same case or controversy under Article III of
    the United States Constitution. Such supplemental jurisdiction shall
    include claims that involve the joinder or intervention of additional
    parties.
    
    28 U.S.C. § 1367
    (a). This language reveals four limits on the reach of § 1367(a).
    First, § 1367(a) does not authorize supplemental jurisdiction where “expressly
    provided otherwise by Federal statute.” In this case, none of the parties or the amicus
    05-1238
    8
    curiae cite any statute, and we have found none, that expressly strips federal courts of
    supplemental jurisdiction of claims arising under either foreign patents or foreign laws.
    Second, § 1367(a) lists subsection (b) as an exception. Subsection (b) pertains
    to “any civil action of which the district courts have original jurisdiction founded solely
    on” diversity and thus, is not relevant here.
    Third, § 1367(a) also lists subsection (c) as an exception.            We discuss
    subsection (c), which enumerates the circumstances under which the “district courts
    may decline to exercise supplemental jurisdiction,” in infra Part III.A.2.
    Fourth, § 1367(a) authorizes supplemental jurisdiction only over claims that are
    “so related to claims in the action within such original jurisdiction that they form part of
    the same case or controversy under Article III of the United States Constitution.” This
    statutory “case or controversy” language extends to the limits of Article III. See, e.g.,
    Jones v. Ford Motor Credit Co., 
    358 F.3d 205
    , 212 n.5 (2d Cir. 2004); Baer v. First
    Options of Chicago, Inc., 
    72 F.3d 1294
    , 1299 (7th Cir. 1995).
    In this case, it is undisputed that the district court has original federal question
    jurisdiction over Voda’s U.S. patent infringement claims. In addition, § 1367(a) appears
    to authorize supplemental jurisdiction over foreign law claims in certain limited
    circumstances. Specifically, § 1367(a) provides the statutory authority for federal courts
    to exercise supplemental jurisdiction over claims that are outside the limited original
    jurisdiction of federal district courts, including those within the general jurisdiction of
    state courts. Therefore, because the “inherent powers” of state courts “permit them to
    entertain transitory causes of action arising under the laws of foreign sovereigns,” Tafflin
    v. Levitt, 
    493 U.S. 455
    , 470 (1990) (Scalia, J., concurring) (citing McKenna v. Fisk, 42
    05-1238
    9
    U.S. (1 How.) 241, 247-249 (1843)), § 1367 supplemental jurisdiction appears to include
    foreign law claims. See also Printz v. United States, 
    521 U.S. 898
    , 907 (1997) (“[U]nlike
    legislatures and executives, [courts] applied the law of other sovereigns all the time.”).
    Therefore, the § 1367(a) issue we discuss here is whether Voda’s claims of foreign
    patent infringement “form part of the same case or controversy under Article III.”
    a.     “Common nucleus of operative fact”
    The Supreme Court has interpreted the statutory requirement of § 1367(a) that
    foreign claims be “so related to claims in the action within such original jurisdiction that
    they form part of the same case or controversy” as Congress’s codification of the
    Court’s
    principles of pendent and ancillary jurisdiction by which the federal
    courts’ original jurisdiction over federal questions carries with it
    jurisdiction over state law claims that “derive from a common
    nucleus of operative fact,” such that “the relationship between [the
    federal] claim and the state claim permits the conclusion that the
    entire action before the court comprises but one constitutional
    ‘case.’”
    Chicago, 
    522 U.S. at 164-65
     (quoting United Mine Workers of Am. v. Gibbs, 
    383 U.S. 715
    , 725 (1966)) (additional citations omitted) (emphasis added); see also 13B Wright,
    Miller, Cooper & Freer, Federal Practice & Procedure § 3567.1, at n.42 (2d ed. Supp.
    2005).
    With regard to the relationship between foreign and U.S. patent infringement
    claims, we stated in Stein that “the issues are not the same” where “one action
    involv[es] United States patents and the other involv[es] British patents.” 
    748 F.2d at 658
    . Mars, 
    24 F.3d 1368
    , however, is the first and only case of this court that expressly
    evaluates whether supplemental jurisdiction under § 1367(a) extends to infringement
    05-1238
    10
    claims based on foreign patents. In Mars, we applied the “common nucleus of operative
    fact” rubric to determine whether § 1367(a) authorized supplemental jurisdiction over an
    infringement claim based on a Japanese patent. We held that “the district court erred in
    assuming that it had ‘power’ to hear the Japanese patent infringement claim under
    section 1367(a).”     Id. at 1375.    Based on the facts alleged in the complaint, we
    reasoned:
    We conclude that the foreign patent infringement claim at issue
    here is not so related to the U.S. patent infringement claim that the
    claims form part of the same case or controversy and would thus
    ordinarily be expected to be tried in one proceeding. [1] The
    respective patents are different, [2] the accused devices are
    different, [3] the alleged acts are different, and [4] the governing
    laws are different. The assertion of supplemental jurisdiction over
    the Japanese infringement claim would in effect result in the trial
    court having to conduct two separate trials at one time.
    Id. Regarding the first three factors, we noted (1) that in the U.S. patent “[a]ll three
    claims are method claims directed to the electronic examination and identification of
    coins” whereas “[i]n contrast, the sole claim of the Japanese Patent . . . is an apparatus
    claim that does not literally contain the limitations of [the asserted] claims . . . of the U.S.
    patent”; (2) that the claims of U.S. and Japanese patent infringement focused on
    different devices and that “the range of accused devices in Japan is much broader than
    in the United States”; and (3) that although Mars charged the defendant with acts of
    both direct and induced infringement of its U.S. patent, it charged the defendant with
    only direct infringement of the Japanese patent. Id.
    In this case, Voda does not dispute the assertion of Cordis U.S. that the
    “governing laws in each of the foreign courts differ in important ways.” The parties
    dispute whether the patents are different. Cordis U.S. asserts that the patents differ
    05-1238
    11
    materially, while Voda asserts that they differ only in slight respects.6 With respect to
    the other factors, however, there appear to be more commonalities than in Mars.
    Voda’s amended complaint identifies Cordis U.S.’s XB guiding catheter as the accused
    device for the domestic and foreign infringement claims. Voda also alleges the same
    type of direct infringement, i.e., making, offering for sale, and selling, for all infringement
    claims.
    In addition, it is important to note that Mars does not supplant the “common
    nucleus of operative fact” test established by the Supreme Court in Gibbs and codified
    by Congress in § 1367(a). Mars simply listed four differences between the claims in
    that particular case that were sufficient for finding no “common nucleus of operative
    fact.” As such, while providing precedential guidance, Mars did not establish either an
    exhaustive list of the factors district courts may consider under § 1367(a) or the
    necessary conditions for a finding of no supplemental jurisdiction.
    The district court failed to articulate any such analysis. The district court correctly
    observed that Mars did not establish a per se rule preventing U.S. courts from asserting
    supplemental jurisdiction to adjudicate foreign patents, but then summarily concluded
    that the “allegations in the amended complaint demonstrate that this case [wa]s more
    akin to Ortman[, 
    371 F.2d 154
     (7th Cir. 1967),] than to Mars.               Based on those
    allegations, the [district] court [found] that it would have supplemental jurisdiction over
    the foreign patents claims.” Voda, slip op. at 2. Even if we agreed that this case were
    6
    Therefore, none of the parties would agree with the dissent’s conclusions
    that “the specifications are the same” or that the patents “are identical.” Dissent 10, 13.
    Moreover, it is unclear how the dissent arrives at these conclusions when the French
    and German patents are in different languages, and the record on appeal provides no
    translations.
    05-1238
    12
    “more akin” to Ortman than Mars, that does not answer the legal question of whether
    there is a “common nucleus of operative fact” in this case.
    Here, the district court did not articulate any findings regarding the Mars factors.7
    Moreover, although the determination of foreign law is a question of law, we as an
    appellate court cannot take any expert testimony to determine the extent of the
    differences in the governing laws. See Fed. R. Civ. P. 44.1 (governing determination of
    foreign law).        Since the scope of a foreign patent depends on foreign law, such
    testimony would also inform a comparison of the patents themselves.                 Therefore,
    because we hold in infra Part III.A.2 that the district court abused its discretion under
    § 1367(c), we deem it to be the more prudent course not to decide this “common
    nucleus of operative fact” question in the first instance.
    b.       “Ordinarily be expected to try them all in one judicial proceeding”
    Seizing on the Supreme Court’s language in Gibbs, one of the amicus curiae
    asserts that in determining the existence of “the same case or controversy” under
    § 1367(a), we must examine not only whether there is a “common nucleus of operative
    fact,” but also whether a district court would “ordinarily be expected to try [domestic and
    foreign patent infringement claims] all in one judicial proceeding.”
    While courts generally focus on the phrase “common nucleus of operative fact,”
    there is an ambiguity in Gibbs, in which the Supreme Court stated:
    7
    The Supreme Court has stated that “where issues arise as to jurisdiction
    or venue, discovery is available to ascertain the facts bearing on such issues.”
    Oppenheimer Fund, Inc. v. Sanders, 
    437 U.S. 340
    , 351 n.13 (1978) (citation omitted).
    The dissent cites no authority to the contrary to support its position that it is “unfair” and
    “inappropriate to criticize the judge for not making findings or taking evidence at the
    pleading stage.” Dissent 11.
    05-1238

    The federal claim must have substance sufficient to confer subject
    matter jurisdiction on the court. The state and federal claims must
    derive from a common nucleus of operative fact. But if, considered
    without regard to their federal or state character, a plaintiff’s claims
    are such that he would ordinarily be expected to try them all in one
    judicial proceeding, then, assuming substantiality of the federal
    issues, there is power in federal courts to hear the whole.
    
    383 U.S. at 725
     (citation and footnote omitted) (emphasis added). From the text of
    Gibbs, it is therefore unclear how the phrases “common nucleus of operative fact” and
    “ordinarily be expected to try them all in one judicial proceeding” relate.
    The Court’s subsequent use of the Gibbs language indicates that the phrases
    could represent two separate and necessary tests or that the phrase “ordinarily be
    expected” is irrelevant. Compare Exxon, 
    125 S. Ct. at 2632
     (Ginsburg, J., dissenting)
    (“‘[T]here is power in federal courts to hear the whole,’ the Court said, when the state
    and federal claims ‘derive from a common nucleus of operative fact’ and are so linked
    that the plaintiff ‘would ordinarily be expected to try them all in one judicial proceeding.’”
    (emphasis added)), and Carnegie-Mellon Univ. v. Cohill, 
    484 U.S. 343
    , 349 (1988)
    (“The Court stated that a federal court has jurisdiction over an entire action, including
    state-law claims, whenever the federal-law claims and state-law claims in the case
    ‘derive from a common nucleus of operative fact’ and are ‘such that [a plaintiff] would
    ordinarily be expected to try them all in one judicial proceeding.’” (emphasis added)),
    with Chicago, 
    522 U.S. at 165
     (“[T]he state and federal claims ‘derive from a common
    nucleus of operative fact,’ . . . . That is all the statute requires to establish supplemental
    jurisdiction.” (citation omitted) (emphasis added)).
    Similarly, this court’s use of the Gibbs language indicates that the phrases could
    represent two separate and necessary tests or that the phrase “ordinarily be expected
    05-1238
    14
    to try them all in one judicial proceeding” merely informs the “common nucleus of
    operative fact” analysis. Compare Stark v. Advanced Magnetics, Inc., 
    29 F.3d 1570
    ,
    1578 (Fed. Cir. 1994) (finding § 1367 requirements met where “there is a substantial
    federal claim; the federal and state claims derive from common operative facts; and the
    plaintiff would normally expect to try all of the claims in a single proceeding”), with
    Highway Equip. Co., Inc. v. FECO, Ltd., 
    469 F.3d 1027
    , 1037-38 (Fed. Cir. 2006) (“For
    this relatedness requirement to be satisfied, ‘[t]he state and federal claims must derive
    from a common nucleus of operative fact’ such that they would ordinarily be expected to
    be tried in one proceeding.” (citation omitted)), and Mars, 
    24 F.3d at 1374
     (“The Court
    further explained that the requisite relatedness between the federal and non-federal
    claims exists for jurisdictional purposes when the claims derive from a ‘common nucleus
    of operative fact,’ and as such, would ordinarily be expected to be tried in one
    proceeding.”).
    If the phrase “ordinarily be expected to try them all in one judicial proceeding”
    does play a role in the scope of § 1367(a) authorization via Gibbs, district courts may be
    unable to exercise supplemental jurisdiction over claims based on foreign patents if the
    norm is that patent claims are adjudicated by the courts within the jurisdiction where
    such patents are created. Neither the Supreme Court nor this court, however, has
    addressed whether the phrase “ordinarily be expected to try them all in one judicial
    proceeding” constitutes an independent requirement under the “same case or
    controversy requirement” of § 1367(a). Because the district court abused its discretion
    under § 1367(c), however, we need only state in this case that none of the briefs have
    persuaded us to hold that such an additional requirement exists.
    05-1238
    15
    Accordingly, we refrain from deciding whether Voda’s foreign patent infringement
    claims fall within the scope of the “same case or controversy” requirement of § 1367(a).
    2.      Discretion
    Section 1367 “reaffirms that the exercise of supplemental jurisdiction is within the
    discretion of the district court.” Mars, 
    24 F.3d at 1374
    ; see also Chicago, 
    522 U.S. at 172
     (stating that supplemental jurisdiction statute codifies principle “that pendent
    jurisdiction ‘is a doctrine of discretion, not of plaintiff’s right,’ and that district courts can
    decline to exercise jurisdiction over pendent claims for a number of valid reasons”
    (quoting Gibbs, 
    383 U.S. at 726
    )).           A district court’s discretion, however, is not
    unfettered, and we review the district court’s decision not to decline supplemental
    jurisdiction under 
    28 U.S.C. § 1367
    (c) under an abuse of discretion standard. Mars, 
    24 F.3d at
    1375 n.4; see also Marcus v. AT&T Corp., 
    138 F.3d 46
    , 57 (2d Cir. 1998) (“We
    review the decision of the district court to exercise supplemental jurisdiction over state
    law claims for an abuse of discretion.”). We address the limits of that discretion here
    and conclude that the district court’s exercise of supplemental jurisdiction over Voda’s
    foreign patent infringement claims is independently limited by subsection (c).
    Section 1367(c) provides:
    The district courts may decline to exercise supplemental jurisdiction
    over a claim under subsection (a) if—
    (1) the claim raises a novel or complex issue of State law,
    (2) the claim substantially predominates over the claim or claims
    over which the district court has original jurisdiction,
    (3) the district court has dismissed all claims over which it has
    original jurisdiction, or
    (4) in exceptional circumstances, there are other compelling
    reasons for declining jurisdiction.
    05-1238
    16
    
    28 U.S.C. § 1367
    (c). The Supreme Court has noted that the “statute thereby reflects
    the understanding that, when deciding whether to exercise supplemental jurisdiction, ‘a
    federal court should consider and weigh in each case, and at every stage of the
    litigation, the values of judicial economy, convenience, fairness, and comity.’” Chicago,
    
    522 U.S. at 173
     (citation omitted).
    Voda asserts that such considerations “have nothing to do with, the certified
    question concerning existence of subject-matter jurisdiction.” We disagree. The text of
    § 1367(a) indicates § 1367(c) constitutes an express statutory exception to the
    authorization of jurisdiction granted by § 1367(a). In this case, Cordis U.S. asserted
    that the district court should exercise its discretion to decline supplemental jurisdiction of
    Voda’s foreign patent claims at the end of its opposition to Voda’s motion to amend the
    complaint. The district court’s order contained no § 1367(c) analysis. We find that
    considerations of comity, judicial economy, convenience, fairness, and other
    exceptional circumstances constitute compelling reasons to decline jurisdiction under
    § 1367(c) in this case and therefore, hold that the district court abused its discretion by
    assuming jurisdiction.
    a.     Treaties as the “supreme law of the land”
    Article VI of the Constitution proclaims that “all treaties made, or which shall be
    made, under the authority of the United States, shall be the supreme law of the land.”
    U.S. Const. art. VI, cl.2. The Supreme Court has accordingly stated that “a treaty
    ratified by the United States is not only the law of this land, see U.S. Const., Art. II, § 2,
    but also an agreement among sovereign powers.” El Al Isr. Airlines, Ltd. v. Tsui Yuan
    Tseng, 
    525 U.S. 155
    , 167 (1999) (citation omitted).

    17
    The United States entered into Articles 13 through 30 of the Paris Convention for
    the Protection of Industrial Property (“Paris Convention”) on September 5, 1970 and
    Articles 1 through 12 of the Paris Convention on August 25, 1973. Paris Convention,
    art. 13-30, 21 U.S.T. 1583; 
    id.,
     art. 1-12, 24 U.S.T. 2140. Article 4bis of the Paris
    Convention states that U.S. patents “shall be independent of patents obtained for the
    same invention in other countries” and that the “foregoing provision is to be understood
    in an unrestricted sense, . . . both as regards the grounds for nullity and forfeiture.” In
    addition, Article 2(3) of the Paris Convention states that the “provisions of the laws of
    each of the countries of the Union relating to judicial and administrative procedure and
    to jurisdiction, . . . which may be required by the laws on industrial property are
    expressly reserved.” The Paris Convention thus clearly expresses the independence of
    each country’s sovereign patent systems and their systems for adjudicating those
    patents. Nothing in the Paris Convention contemplates nor allows one jurisdiction to
    adjudicate the patents of another, and as such, our courts should not determine the
    validity and infringement of foreign patents. Accordingly, while the Paris Convention
    contains no express jurisdictional-stripping statute, we relied on it in Stein to hold that
    “[o]nly a British court, applying British law, can determine validity and infringement of
    British patents.” 
    748 F.2d at 658
    .
    Subsequently, the United States adopted the Patent Cooperation Treaty (“PCT”)
    on January 24, 1978. Patent Cooperation Treaty, 28 U.S.T. 7645. As with the Paris
    Convention, the text of the PCT maintains the independence of each country’s patents.
    Article 27(5) states: “Nothing in this Treaty and the Regulations is intended to be
    05-1238
    18
    construed as prescribing anything that would limit the freedom of each Contracting
    State to prescribe such substantive conditions of patentability as it desires.”
    On January 1, 1995, the United States joined the World Trade Organization by
    entering the Marrakesh Agreement Establishing the World Trade Organization, which
    through Article II § 2 binds all of its members to the Agreement on Trade-Related
    Aspects of Intellectual Property Rights (“TRIPS”). 1867 U.N.T.S. 154, 33 I.L.M. 1144
    (Apr. 15, 1994). The Agreement on TRIPS contains several provisions regarding the
    enforcement of patents. Article 41 § 1 of the Agreement on TRIPS specifies that each
    country “shall ensure that enforcement procedures as specified in this Part are available
    under their law so as to permit effective action against any act of infringement of
    intellectual property rights.” In addition, § 4 states that “[p]arties to a proceeding shall
    have an opportunity for review by a judicial authority of final administrative decisions
    and, subject to jurisdictional provisions in a Member’s law concerning the importance of
    a case,” and § 5 states “[i]t is understood that this Part does not . . . affect the capacity
    of Members to enforce their law in general.” See also id., art. 41-49. Like the Paris
    Convention, nothing in the PCT or the Agreement on TRIPS contemplates or allows one
    jurisdiction to adjudicate patents of another.8     Canada, France, Germany, and the
    United Kingdom, which are the foreign sovereigns concerned in this case, are parties to
    8
    While the European Patent Convention (“EPC”) states nothing of our
    government’s intent because the United States is not a party, it may inform us on how
    other sovereigns treat foreign patent adjudication. Regarding claims “to the right to the
    grant of a European patent,” the EPC has enumerated rules specifying courts of
    exclusive jurisdiction. European Patent Convention, Protocol on Recognition, art. 1-8,
    October 5, 1973. None of the treaties entered into by the United States contain such
    language. Moreover, while there have been working parties and draft agreements and
    statutes, even the members of the EPC have not yet agreed on a centralized European
    patent court. See European Patent Office, “Legislative Initiatives in European Patent
    Law” (July 26, 2006), available at http://patlaw-reform.european-patent-office.org/epla/.

    each of these treaties. See World Intellectual Property Organization, “States Party to
    the PCT and the Paris Convention and Members of the World Trade Organization”
    (2006), available at http://www.wipo.int/pct/en/texts/pdf/pct_paris_wto.pdf.
    Voda asserts and one of the amicus curiae briefs suggests that these
    international treaties evince a trend of harmonization of patent law and thus, that
    allowing the exercise of supplemental jurisdiction over Voda’s foreign patent
    infringement claims furthers the harmonization goals underlying the treaties.
    Regardless of the strength of the harmonization trend, however, we as the U.S. judiciary
    should not unilaterally decide either for our government or for other foreign sovereigns
    that our courts will become the adjudicating body for any foreign patent with a U.S.
    equivalent “so related” to form “the same case or controversy.”        Cf. F. Hoffman-La
    Roche Ltd. v. Empagran S.A., 
    542 U.S. 155
    , 166-67 (2004) (finding “no convincing
    justification” for providing such subject matter jurisdiction in antitrust context).
    Permitting our district courts to exercise jurisdiction over infringement claims based on
    foreign patents in this case would require us to define the legal boundaries of a property
    right granted by another sovereign and then determine whether there has been a
    trespass to that right.
    Based on the international treaties that the United States has joined and ratified
    as the “supreme law of the land,” a district court’s exercise of supplemental jurisdiction
    could undermine the obligations of the United States under such treaties, which
    05-1238
    20
    therefore constitute an exceptional circumstance to decline jurisdiction under
    § 1367(c)(4). Accordingly, we must scrutinize such an exercise with caution.9
    b.     Comity and relations between sovereigns
    “Comity refers to the spirit of cooperation in which a domestic tribunal
    approaches the resolution of cases touching the laws and interests of other sovereign
    states.” Société Nationale Industrielle Aérospatiale v. U.S. Dist. Court for the S.D. of
    Iowa, 
    482 U.S. 522
    , 543 n.27 (1987).
    Comity, in the legal sense, is neither a matter of absolute
    obligation, on the one hand, nor of mere courtesy and good will,
    upon the other. But it is the recognition which one nation allows
    within its territory to the legislative, executive or judicial acts of
    another nation, having due regard both to international duty and
    convenience, and to the rights of its own citizens or of other
    persons who are under the protection of its laws.

     (quoting Hilton v. Guyot, 
    159 U.S. 113
    , 163-64 (1895)) (quotation marks omitted)
    (emphasis added). Courts must also bear in mind that “whatever laws are carried into
    execution, within the limits of any government, are considered as having the same
    effect every where, so far as they do not occasion a prejudice to the rights of the other
    governments, or their citizens.”

    In addition, even assuming that Cordis U.S. is responsible for
    manufacturing the allegedly infringing devices in Juarez, Mexico, and selling them in
    foreign countries, the dissent’s assertion that we could adjudicate a foreign patent
    infringement action and enforce the judgment against Cordis U.S. for its foreign
    manufacturing and foreign sales, Dissent 1 n.1, would be an end-run around the
    territorial limits of 
    35 U.S.C. § 271
    . See Dowagiac, 235 U.S. at 650 (“The right
    conferred by a patent under our law is confined to the United States and its territories.”
    (citation omitted)); cf. AT&T Corp. v. Microsoft Corp., 
    414 F.3d 1366
     (Fed. Cir. 2005),
    cert. granted, 
    127 S. Ct. 467
     (2006).
    05-1238
    21
    comity supports extending or declining jurisdiction over the foreign patent infringement
    claims at issue here. See 
    id. at 543-44
     (stating that international comity concept in
    evidence-gathering context requires particularized analysis of facts and sovereign
    interests).
    In this case, these considerations of comity do not support the district court’s
    exercise of supplemental jurisdiction over Voda’s foreign patent infringement claims.
    First, Voda has not identified any international duty, and we have found none, that
    would require our judicial system to adjudicate foreign patent infringement claims. As
    discussed supra Part III.A.2.a, while the United States has entered into the Paris
    Convention, the PCT, and the Agreement on TRIPS, nothing in those treaties
    contemplates or allows one jurisdiction to adjudicate the patents of another. Second, as
    discussed infra Part III.A.2.d, Voda has not shown that it would be more convenient for
    our courts to assume the supplemental jurisdiction at issue. Third, with respect to the
    rights of our citizens, Voda has not shown that foreign courts will inadequately protect
    his foreign patent rights.   Indeed, we see no reason why American courts should
    supplant British, Canadian, French, or German courts in interpreting and enforcing
    British, Canadian, European, French, or German patents. Cf. Empagran, 
    542 U.S. at 165
     (finding no reason to allow “American [antitrust] law [to] supplant, for example,
    Canada’s or Great Britain’s or Japan’s own determination about how best to protect
    Canadian or British or Japanese customers from anticompetitive conduct”).
    Fourth, assuming jurisdiction over Voda’s foreign patent infringement claims
    could prejudice the rights of the foreign governments. None of the parties or amicus
    curiae have demonstrated that the British, Canadian, French, or German governments
    05-1238
    22
    are willing to have our courts exercise jurisdiction over infringement claims based on
    their patents. Cf. 
    28 U.S.C. § 1338
    (a) (granting federal courts exclusive jurisdiction of
    claims relating to U.S. patents).
    In addition, the local action doctrine informs us that exercising supplemental
    jurisdiction in this case appears to violate our own norms of what sovereigns ordinarily
    expect. Courts derived the local action doctrine from the distinction between local and
    transitory actions beginning with Livingston v. Jefferson, written by Justice John
    Marshall riding Circuit. 
    15 F. Cas. 660
     (C.C.D. Va. 1811). In Livingston, the plaintiff
    sued in a Virginia court for trespass to land located in Louisiana. The court dismissed
    the action, holding that it could be brought only in a Louisiana court. The Supreme
    Court subsequently held that “an action for trespass upon land, like an action to recover
    the title or the possession of the land itself, is a local action, and can only be brought
    within the State in which the land lies.” Ellenwood v. Marietta Chair Co., 
    158 U.S. 105
    ,
    107 (1895). The Court concluded that a federal court sitting in another state had no
    jurisdiction to hear the trespass claim. 
    Id.
     In short, the local action doctrine served to
    prevent courts from adjudicating claims for trespass or title to real property.
    The territorial limits of the rights granted by patents are similar to those conferred
    by land grants. A patent right is limited by the metes and bounds of the jurisdictional
    territory that granted the right to exclude. See Dowagiac Mfg. Co. v. Minn. Moline Plow
    Co., 
    235 U.S. 641
    , 650 (1915) (“The right conferred by a patent under our law is
    confined to the United States and its territories.” (citation omitted)); NTP, Inc. v.
    Research In Motion, Ltd., 
    418 F.3d 1282
    , 1313 (Fed. Cir. 2005) (“The territorial reach of
    section 271 is limited. Section 271(a) is only actionable against patent infringement that
    05-1238
    23
    occurs within the United States.” (citations omitted)).       Therefore, a patent right to
    exclude only arises from the legal right granted and recognized by the sovereign within
    whose territory the right is located. It would be incongruent to allow the sovereign
    power of one to be infringed or limited by another sovereign’s extension of its
    jurisdiction.   Therefore, while our Patent Act declares that “patents shall have the
    attributes of personal property,” 
    35 U.S.C. § 261
    , and not real property, the local action
    doctrine constitutes an informative doctrine counseling us that exercising supplemental
    jurisdiction over Voda’s foreign patent claims could prejudice the rights of the foreign
    governments.
    Therefore, the four considerations enunciated by the Supreme Court in Société
    demonstrate that extending our jurisdiction through § 1367(a) in this case could
    undermine “the spirit of cooperation” underlying the comity doctrine.          Because the
    purpose underlying comity is not furthered and potentially hindered in this case,
    adjudication of Voda’s foreign patent infringement claims should be left to the
    sovereigns that create the property rights in the first instance.
    In addition, as a rule of statutory construction, the Supreme Court “ordinarily
    construes ambiguous statutes to avoid unreasonable interference with the sovereign
    authority of other nations.” Empagran, 
    542 U.S. at 164
    ; cf. Santa Clara Pueblo v.
    Martinez, 
    436 U.S. 49
    , 60 (1978) (“[A] proper respect both for tribal sovereignty itself
    and for the plenary authority of Congress in [civil actions against tribal officers] cautions
    that we tread lightly in the absence of clear indications of legislative intent.”).        As
    discussed, there is no explicit statutory direction indicating that the district courts should
    or may exercise supplemental jurisdiction over claims arising under foreign patents, and
    05-1238
    24
    the Paris Convention, PCT, and Agreement on TRIPS neither contemplate nor allow the
    extraterritorial jurisdiction of our courts to adjudicate patents of other sovereign nations.
    We have also noted the territorially limited nature of patent rights. See Pellegrini v.
    Analog Devices, Inc., 
    375 F.3d 1113
    , 1117 (Fed. Cir. 2004) (“[As] the U.S. Supreme
    Court explained nearly 150 years ago in Brown v. Duchesne, 60 U.S. (19 How.) 183,
    
    15 L. Ed. 595
     (1857), . . . the U.S. patent laws ‘do not, and were not intended to,
    operate beyond the limits of the United States.’”); Rotec Indus., Inc. v. Mitsubishi Corp.,
    
    215 F.3d 1246
    , 1251 (Fed. Cir. 2000) (“‘[T]he right conferred by a patent under our law
    is confined to the United States and its territories, and infringement of this right cannot
    be predicated on acts wholly done in a foreign country.’” (quoting Dowagiac, 
    235 U.S. at 650
    )). Therefore, the principle that we should “avoid unreasonable interference with the
    sovereign authority of other nations” applies analogously here. Empagran, 
    542 U.S. at 164
    .
    We would risk such interference by exercising supplemental jurisdiction over
    Voda’s foreign patent infringement claims. Patents and the laws that govern them are
    often described as complex.       Indeed, one of the reasons cited for why Congress
    established our court was because it “felt that most judges didn’t understand the patent
    system and how it worked.” Judge Pauline Newman, Origins of the Federal Circuit: The
    Role of Industry, 
    11 Fed. Cir. B.J. 541
    , 542 (2002). As such, Cordis U.S. and one of the
    amicus curiae assert, and Voda does not dispute, that the foreign sovereigns at issue in
    this case have established specific judges, resources, and procedures to “help assure
    the integrity and consistency of the application of their patent laws.”           Therefore,
    exercising jurisdiction over such subject matter could disrupt their foreign procedures.
    05-1238
    25
    By analogy, Congress unified our patent jurisprudence by creating the Federal Circuit
    and granting exclusive jurisdiction of appeals on patent claims.          
    28 U.S.C. § 1295
    .
    Foreign courts exercising jurisdiction over claims based on U.S. patents would destroy
    Congress’s intent to foster uniformity and to preclude forum shopping. Cf. Empagran,
    
    542 U.S. at 168-69
     (finding in antitrust context that “legally and economically technical
    nature of [examining foreign law, compared with American law] means lengthier
    proceedings, appeals, and more proceedings-to the point where procedural costs and
    delays could themselves threaten interference with a foreign nation’s ability to maintain
    the integrity of its own antitrust enforcement system”).
    Accordingly, comity and the principle of avoiding unreasonable interference with
    the authority of other sovereigns dictate in this case that the district court decline the
    exercise supplemental jurisdiction under § 1367(c).
    c.     Judicial economy
    Because of our lack of institutional competence in the foreign patent regimes at
    issue in this case, more judicial resources could be consumed by the district court than
    the courts of the foreign patent grants.           Indeed, adjudication of Voda’s British,
    Canadian, European, French, and German patent claims may substantially predominate
    his U.S. patent claims.      Cf. § 1367(c)(2) (stating that district courts may decline
    exercising supplemental jurisdiction where “the claim substantially predominates over
    the claim or claims over which the district court has original jurisdiction”).
    In addition, the likelihood of jury confusion in applying different patent regimes
    could result in separate trials.    Cf. Gibbs, 
    383 U.S. at 726
     (“Finally, there may be
    reasons independent of jurisdictional considerations, such as the likelihood of jury
    05-1238
    26
    confusion in treating divergent legal theories of relief, that would justify separating state
    and federal claims for trial, Fed.Rule Civ.Proc. 42(b).”).           Therefore, exercising
    supplemental jurisdiction in this case could result in at least the same magnitude of
    litigation as Voda filing patent infringement claims in each respective sovereign’s court.
    Voda and one amicus curiae point out that consolidated multinational patent
    adjudication could be more efficient. While there may be merit in that argument, no
    international treaty establishes full faith and credit, nor have we found any analogous
    agreement that would require foreign countries to recognize or obligate the enforcement
    of our judgments regarding foreign patents. In this case, Voda’s amended complaint
    asks not only for damages and fees but also for “such other and further relief as this
    Court deems just and proper.” Therefore, the additional time and resources required by
    our courts may result in incomplete adjudication of the claims, prolonging and extending
    the expenditures by all.
    The district court did not articulate any such judicial economy analysis, and
    accordingly, this absence of analysis supports our finding that the district court abused
    its discretion in this case.
    d.     Convenience
    Similarly, factors of convenience may provide additional reasons to decline
    exercising supplemental jurisdiction in this case.       Again, the district court did not
    articulate any such analysis, further supporting our finding that it abused its discretion.
    We note that the Supreme Court does not appear to have defined convenience in
    the context of discretionary exercises of supplemental jurisdiction. While the parties
    have structured their arguments in this case around forum non conveniens, they have
    05-1238
    27
    provided no case law justifying incorporation of that doctrine into the consideration of
    convenience under § 1367(c). Cf. Piper Aircraft Co. v. Reyno, 
    454 U.S. 235
    , 248 n.13
    (1981) (noting that Supreme Court first indicated that motions to dismiss on grounds of
    forum non conveniens could be made in federal diversity actions in Williams v. Green
    Bay & W.R. Co., 
    326 U.S. 549
     (1946)); Capital Currency Exch., N.V. v. Nat’l
    Westminster Bank PLC, 
    155 F.3d 603
    , 606 (2d Cir. 1998) (stating that Supreme Court
    explicitly recognized applicability of forum non conveniens in federal question cases in
    Gulf Oil Corp. v. Gilbert, 
    330 U.S. 501
     (1947)). Where the doctrine does not duplicate
    other factors already considered, however, forum non conveniens is a useful doctrine to
    reference. For example, on one hand, the cost of obtaining and translating evidence,
    especially experts in foreign patent law pursuant to Fed. R. Civ. P. 44.1 (governing
    determination of foreign law), cuts against exercising supplemental jurisdiction. On the
    other hand, deferring to the plaintiff’s choice of forum would support such an exercise.
    e.     Fairness
    Lastly, the act of state doctrine may make the exercise of supplemental
    jurisdiction over foreign patent infringement claims fundamentally unfair. As “a ‘principle
    of decision binding on federal and state courts alike,’” the act of state doctrine “requires
    that, in the process of deciding, the acts of foreign sovereigns taken within their own
    jurisdictions shall be deemed valid.” W.S. Kirkpatrick & Co., Inc. v. Envtl. Tectonics
    Corp., Int’l, 
    493 U.S. 400
    , 406, 409 (1990) (citation omitted). In this case, none of the
    parties or amicus curiae have persuaded us that the grant of a patent by a sovereign is
    not an act of state. But see Mannington Mills, Inc. v. Congoleum Corp., 
    595 F.2d 1287
    ,
    1293-94 (3d Cir. 1979) (stating that Third Circuit was “unable to accept the proposition
    05-1238
    28
    that the mere issuance of patents by a foreign power constitutes [] an act of state” under
    abstention analysis).   Therefore, assuming arguendo that the act of state doctrine
    applies, the doctrine would prevent our courts from inquiring into the validity of a foreign
    patent grant and require our courts to adjudicate patent claims regardless of validity or
    enforceability. Given the number of U.S. patent cases that we resolve on validity or
    enforceability as opposed to infringement grounds, exercising such jurisdiction could be
    fundamentally unfair to the alleged infringer where, as one amicus curiae points out,
    “the patent is in fact invalid and the defendant would be excused from liability on that
    basis in a foreign forum.” Voda has not shown in this case that the validity of the foreign
    patents would not be at issue. Indeed, Cordis U.S. asserts otherwise.
    f.     Section 1367(c) abuse of discretion
    In summary, several reasons in this case would compel the district court to
    decline supplemental jurisdiction under § 1367(c): limitations imposed by treaties that
    are the “supreme law of the land” and considerations of comity, judicial economy,
    convenience, and fairness.       The district court undertook none of this analysis.
    Accordingly, we hold that the district court abused its discretion in exercising
    supplemental jurisdiction.
    As with the § 1367(a) factors of Mars, this is a non-exhaustive list, not a test, for
    district courts to consider under § 1367(c). In addition, we emphasize that because the
    exercise of supplemental jurisdiction under § 1367(c) is an area of discretion, the district
    courts should examine these reasons along with others that are relevant in every case,
    especially if circumstances change, such as if the United States were to enter into a
    new international patent treaty or if events during litigation alter a district court’s
    05-1238
    29
    conclusions regarding comity, judicial economy, convenience, or fairness. However,
    “[d]iscretion is not whim, and limiting discretion according to legal standards helps
    promote the basic principle of justice that like cases should be decided alike . . . a page
    of history is worth a volume of logic.” eBay, 126 S. Ct. at 1841-42 (Roberts, C.J.,
    concurring) (quotation marks and citations omitted).
    B.     Alternate Statutory Basis
    The parties also dispute on appeal whether diversity jurisdiction under § 1332
    provides an alternate and independent basis for the district court to hear Voda’s claims
    of foreign patent infringement. However, Voda has not pled diversity, and it is not clear
    whether the district court would permit such a pleading to be made at this stage in the
    proceedings. We therefore decline to decide whether the district court could properly
    exercise jurisdiction based in diversity.
    C.     Abstention
    The “district courts may be obligated not to decide” claims arising under foreign
    patents “where one of the abstention doctrines articulated by [the Supreme] Court
    applies.” Chicago, 
    522 U.S. at 174
    . Abstention doctrines “embody the general notion
    that federal courts may decline to exercise their jurisdiction, in otherwise exceptional
    circumstances, where denying a federal forum would clearly serve an important
    countervailing interest, for example where abstention is warranted by considerations of
    proper constitutional adjudication, regard for federal-state relations, or wise judicial
    administration.” 
    Id.
     (quotation marks and citation omitted). Because we resolve the
    district court’s jurisdiction on statutory grounds, we do not discuss or make any holdings
    regarding abstention here.

    IV. CONCLUSION
    We vacate the order of the district court granting Voda leave to amend his
    complaint to add infringement claims based on foreign patents pursuant to the
    supplemental jurisdiction statute 
    28 U.S.C. § 1367
     and remand for further proceedings
    consistent with this opinion.
    VACATED and REMANDED

    United States Court of Appeals for the Federal Circuit
    05-1238
    JAN K. VODA, M.D.,
    Plaintiff-Appellee,
    v.
    CORDIS CORPORATION,
    Defendant-Appellant.
    NEWMAN, Circuit Judge, dissenting.
    I respectfully dissent, for the question here presented is not related to federalism and
    the federal/state relationship, or to pendent jurisdiction of state law issues; nor are disputes
    about foreign patents so unique as to call up the other theories collected by the panel
    majority to support this ousting of United States parties from access to United States
    courts. The certified question is concerned solely with the authority of a United States
    court, having personal jurisdiction of the parties, to exercise its discretion to accept the
    amended complaint concerning the foreign patents corresponding to the United States
    patent in suit.1
    A foreign country is not a "state" in the constitutional context, and the judicial
    application of foreign law plays no role in the jurisdictional balance represented by
    federalism. The rules governing federal jurisdiction of supplemental state claims are
    irrelevant to whether a United States court has the authority and can exercise its discretion
    to decide questions that require the application of foreign law. Courts in the United States
    have always had the authority to decide questions that require application of foreign law.
    Federal Rule of Civil Procedure 44.1 ("Determination of Foreign Law") provides procedural
    guidance. In Printz v. United States, 
    521 U.S. 898
     (1997) the Court, comparing the judicial
    and other branches of government, remarked that courts "applied the law of other
    sovereigns all the time." 
    Id. at 907
    . Yet the panel majority holds that a United States court
    1       Contrary to the statements of the panel majority, my position is not that the
    district court has or needs personal jurisdiction of Cordis' foreign subsidiaries; my premise
    is that the district court has authority and power to provide Voda with the requested relief
    through Cordis US, the manufacturer and provider of the accused catheters for all five
    countries. Further, both the Bonzel and Mars cases, flagged by the majority, were
    discretionary decisions. In Bonzel the contract was made in a foreign country between
    foreign nationals under foreign law, and was declined on the discretionary ground of forum
    non conveniens. In Mars the count against a Japanese company was declined on the
    discretionary ground that the kinds of patents and the structure of the devices differed
    significantly between the United States and Japan.
    05-1238                                      2
    cannot do so, in its sound discretion, when the issue concerns patents. Thus this court
    rules that the district court is precluded from considering the issues concerning the four
    foreign counterparts of the United States patent that is in suit between these parties.
    The district court had agreed to receive the amended complaint. Our role, at this
    pleading stage, is to determine whether that action is supportable. My colleagues hold that
    the district court abused its discretion in exercising supplemental jurisdiction of the foreign
    patent issues, indeed holding that the district court has no discretion to accept this
    amended complaint because it involves foreign patents. I cannot agree. It is inappropriate
    for the Federal Circuit to create this unique exception to the authority of American courts to
    resolve controversies that require the application of foreign law.
    Access of a nation's citizenry to dispute resolution in the nation's courts is
    fundamental to a nation ruled by law. This court's new rule carves an inapt exception into
    judicial authority, judicial obligation, and judicial discretion. Such special treatment of
    patent issues is flawed as a matter of precedent, procedure, and policy.
    Courts Routinely Apply Foreign Law
    Precedent illustrates myriad situations in which the courts have determined and
    applied foreign law, and also illustrates those few situations in which a court has declined to
    resolve a specific foreign-based issue. Today's extreme barrier to exercise of the district
    court's discretion when foreign patents are involved stands alone among the vast variety of
    causes in which such determinations have been made.
    United States courts have determined and applied foreign commercial law, foreign
    property law, foreign inheritance law, foreign citizenship law, foreign copyright law, foreign
    trademark law, foreign liability and negligence law, and other foreign law as appropriate to
    05-1238
    3
    resolution of the dispute between the parties before the court. The principle is that a court
    should apply the same law that would be applied in the nation where the event occurred, or
    the law having the most significant relationship to the event in dispute. For example, in
    Smith v. Condry, 42 U.S. (1 How.) 28 (1843), concerning liability for a collision between
    American vessels in the port of Liverpool, the Court held that the British statutes should be
    applied to determine fault, and that liability and damages should be decided under British
    law. In Nashua Savings Bank v. Anglo-American Land, Mortgage & Agency Co., 
    189 U.S. 221
    , 230 (1903) the Court discussed various methods of proving foreign law, then viewed
    as a question of fact, in an action by an English corporation to recover an assessment on
    its capital stock; the Court explained that: "By subscribing to stock in a foreign corporation,
    defendant subjects itself to the laws of such foreign country in respect to the powers and
    obligations of such corporation." In Uebersee Finanz-Korporation, A.G. v. McGrath, 
    343 U.S. 205
     (1952) the Court held that it was appropriate to determine property ownership of a
    usufructuary under German law, predicate to application of the Trading with the Enemy Act.
    A sampling of recent cases yields further illustration of judicial authority and dispute-
    resolution obligation when foreign law is involved: In Cambridge Literary Properties, Ltd. v.
    W. Goebel Porzellanfabrik G.m.b.H. & Co., 
    295 F.3d 59
     (1st Cir. 2002) the court observed
    that the district court may apply United States copyright law, German contract law, and
    Austrian inheritance law, to resolve all of the issues in the case. In Abogados v. AT&T,
    Inc., 
    223 F.3d 932
     (9th Cir. 2000) the court applied California choice of law analysis to hold
    that the law of Jalisco, Mexico should be applied by the district court to an issue of tortious
    interference with a contract made in Mexico between the Mexican plaintiffs and the
    Mexican subsidiary of AT&T. In Tschira v. Willingham, 
    135 F.3d 1077
     (6th Cir. 1998) the
    05-1238
    4
    court applied German law to decide whether a letter created a fiduciary duty, and then
    applied Tennessee law to a fraudulent misrepresentation concerning property in
    Tennessee. In Curley v. AMR Corp., 
    153 F.3d 5
    , 12 (2nd Cir. 1998) the court compared
    the laws of Mexico and New York as to various torts including false imprisonment and
    negligence, and stated its "agreement with the concept that appellate courts, as well as trial
    courts, may find and apply foreign law"; the court held that foreign law should be applied to
    the acts that occurred in Mexico unless "violative of fundamental notions of justice and
    prevailing concepts of good morals." See generally 9 Charles Alan Wright and Arthur R.
    Miller, Federal Practice and Procedure §§2444-446 at 644-58 (2d ed. 1995) (discussing
    application of foreign law in federal courts).
    In Dorman v. Emerson Electric Co., 
    23 F.3d 1354
     (8th Cir. 1994) the court applied
    the "most significant relationship" test to determine that Canadian law applied to a personal
    injury claim against a product that was designed in Missouri, manufactured in Taiwan, and
    sold and used in Canada. In Indasu Int'l, C.A., v. Citibank, N.A., 
    861 F.2d 375
    , 379 (2nd
    Cir. 1988) the court determined the applicable Ecuadorian law of contracts and guaranty,
    then applied that law to the obligation between the United States guarantor and a
    Panamanian corporation as to a contract to be performed in Ecuadorian waters. In
    Mathews v. ABC Television, Inc., 
    776 F. Supp. 821
     (S.D.N.Y. 1991) a Kenyan film-maker
    sued ABC Television in New York for injuries by a rhinoceros in Kenya, alleging that an
    ABC employee's reckless conduct caused the attack; the district court applied the Kenyan
    comparative negligence law and case law of the East African Court of Appeals. In In re
    Houbigant, Inc., 
    914 F. Supp. 964
     (S.D.N.Y. 1995) the district court applied various
    provisions of the Canadian Trade-Marks Act, and also applied the laws of the Province of
    05-1238
    5
    Quebec and the State of New York to the interpretation of a licensing arrangement. In
    Armstrong v. Virgin Records, Ltd., 
    91 F. Supp.2d 628
     (S.D.N.Y. 2000) the district court
    exercised jurisdiction of the United States and foreign copyright claims, stating that "there is
    no principled reason to bar, in absolute fashion, copyright claims brought under foreign law
    for lack of subject matter jurisdiction," and that "subject matter jurisdiction over any claims
    properly arising under United States copyright law, potentially allowing the Court to exercise
    pendent jurisdiction over claims arising under foreign law." 
    Id. at 637
    .
    As for cases involving foreign patents, in Ortman v. Stanray, 
    371 F.2d 154
     (7th Cir.
    1967) the court approved the exercise of supplemental jurisdiction of counts concerning the
    corresponding Canadian, Brazilian, and Mexican patents. In Mars, Inc. v. Kabushiki-Kaisha
    Nippon Conlux, 
    24 F.3d 1369
     (Fed. Cir. 1994), this court declined to decide the Japanese
    patent issues, explaining that the accused devices, the scope and class of the claims, and
    the charges of infringement were different in Japan and the United States. In Medigene AG
    v. Loyola Univ. of Chicago, No. 98 C 2026, 
    2001 WL 1636916
     (N.D. Ill. Dec. 19, 2001) the
    district court declined to dismiss the issue of inventorship of foreign patent applications,
    stating that "[Mars] makes clear that in appropriate circumstances Section 1367 permits
    exercise of supplemental jurisdiction over a claim for infringement of a foreign patent." 
    Id. at *1
    . In Forbo-Giubiasco S.A. v. Congoleum Corp., 
    516 F. Supp. 1210
     (S.D.N.Y. 1981),
    the court observed that "[a] finding against Congoleum on this point [inequitable conduct in
    obtaining the foreign patents] would affect only the rights between Congoleum and
    Giubiasco, not Congoleum's foreign patent rights generally." 
    Id. at 1218
    . In Distillers Co. v.
    Standard Oil Co., 
    150 USPQ 42
     (N.D. Ohio 1964), in a dispute involving various patents on
    the manufacture of acrylonitrile, the court stated that "It cannot be doubted, nor does the
    05-1238
    6
    plaintiff question, that this Court is empowered to consider claims arising under foreign
    patents." 
    Id.
     (citing Aluminum Co. of Am. v. Sperry Products, Inc., 
    285 F.2d 911
     (6th Cir.
    1950) and Nat'l Latex Products Co. v. Sun Rubber Co., 
    274 F.2d 224
     (6th Cir. 1960)).
    In no case did the court hold that it had no power or authority to receive the foreign
    issue, reciting various reasons in a few situations where the court declined the foreign
    issue. An example is Bonzel v. Pfizer, Inc., 
    439 F.3d 1358
     (Fed. Cir. 2006), where this
    court sustained the district court's discretion in dismissing, on the ground of forum non
    conveniens, an action that required application of German contract law to interpret a patent
    license agreement that was made in Germany between a German national and the Swiss
    subsidiary of a United States company. Other cases are: Vanity Fair Mills, Inc. v. T. Eaton
    Co., 
    234 F.2d 633
    , 645 (2nd Cir. 1956) ("the district court did not abuse its discretion in
    declining to exercise its jurisdiction over that portion of the case arising in Canada and
    governed by Canadian trade-mark law"); Torah Soft Ltd. v. Drosnin, 
    136 F. Supp.2d 276
    (S.D.N.Y. 2001) (district court declined to exercise jurisdiction over foreign copyright claims
    because the United States copyright claim had been dismissed); Berkshire Furniture Co. v.
    Glattstein, 
    921 F. Supp. 1559
    , 1562 (W.D. Ky. 1995) (district court stated that on principles
    of international comity it was "disinclined to decide issues related to the designs that arise
    under U.K. and Malaysian law"); Packard Instrument Co. v. Beckman Instruments, Inc., 
    346 F. Supp. 408
     (N.D. Ill. 1972) (district court declined to resolve patent infringement in nine
    foreign countries, stating that the patentee could obtain effective relief by enforcement of its
    United States patent). In none of these cases was there any assertion of judicial incapacity
    to resolve the foreign issues, or of any prohibition on the exercise of discretion to accept
    the case.
    05-1238
    7
    The district court herein, in exercising its discretion to accept the Voda amended
    complaint, explained that the factual situation in Ortman, supra, was more akin to this case
    than the factual situation in Mars, supra. In Ortman the court had accepted the foreign
    patent issues, stating that "all of the actions of defendant of which complaint is made are
    the result of defendant doing similar acts both in and out of the United States," 
    371 F.2d at 158
    , whereas in Mars, citing the differences in the patents and the products this court held
    that the Japanese issues would more appropriately be resolved by a Japanese court. In
    contrast to the case-specific analyses in precedent, my colleagues now hold that it would
    always be an abuse of discretion for the district court to decide foreign patent issues,
    unless some sort of new treaty is produced. However, it is inappropriate to compel the
    district court to decline the adjudicative authority available in all other areas of law.
    In explaining this unique inroad on discretion when foreign patents are involved, my
    colleagues rely heavily on the criteria of supplemental jurisdiction as codified in 
    28 U.S.C. §1367
    . However, judicial authority to determine and apply foreign law does not require that
    the foreign issue is supplemental to a domestic issue. Further, even if the criteria of §1367
    are applied they support, rather than negate, the district court's decision herein.
    Judicial authority to decide questions of foreign law is not a matter of the
    federal/state relationship codified at 
    28 U.S.C. §1367
    . Nonetheless, the elaboration in
    United Mine Workers of America v. Gibbs, 
    383 U.S. 715
     (1966) concerning federal
    supplemental jurisdiction of state law causes that have "a common nucleus of operative
    fact" is a useful analogy to the Voda/Cordis situation, for the "considerations of judicial
    economy, convenience and fairness to litigants" that are served by supplemental
    jurisdiction, 
    383 U.S. at 726
    , are relevant to considerations of the exercise of judicial
    05-1238
    8
    discretion. If these criteria are applied they reinforce, rather than negate, the district court's
    exercise of discretion to accept Voda's amended complaint.
    The principles of supplemental jurisdiction as applied to federal/state issues, 
    28 U.S.C. §1367
    , weigh on the side of the exercise of jurisdiction absent compelling reason:
    §1367(a). Except as provided in subsections (b) and (c) or as expressly
    provided otherwise by Federal statute, in any civil action of which the district
    courts have original jurisdiction, the district courts shall have supplemental
    jurisdiction over all other claims that are so related to claims within such
    original jurisdiction that they form part of the same case or controversy under
    Article III of the United States Constitution . . . .
    A district court may decline to exercise supplemental jurisdiction over such a related claim:
    §1367(c). The district courts may decline to exercise supplemental
    jurisdiction over a claim under subsection (a) if --
    (1) the claim raises a novel or complex issue of State law,
    (2) the claim substantially predominates over the claim or claims over which
    the district court has original jurisdiction,
    (3) the district court has dismissed all claims over which it has original
    jurisdiction, or
    (4) in exceptional circumstances, there are other compelling reasons for
    declining jurisdiction.
    (All emphases added). Although my colleagues fault the district court for "not making a
    Section 1367(c) analysis," this is an inapt criticism, for the district court did not decline
    jurisdiction by invoking §1367(c); instead, the court applied the principle of §1367(a) and
    accepted the claim, exercising its authority and recognizing its dispute-resolution obligation.
    Indeed, in Exxon Mobil Corp. v. Allapattah Services, Inc., 
    125 S. Ct. 2611
    , 2620 (2005) the
    Court counseled against unduly narrowing the application of §1367(a). The Federal Circuit
    in Mars applied the principles of §1367(c) and held that the Japanese patent issues should
    be litigated in Japan because the "common nucleus of operative fact" required by Gibbs
    was not present, but this court also stated that §1367(c) "reaffirms that the exercise of
    supplemental jurisdiction is within the discretion of the district court." 
    24 F.3d at 1374
    .
    05-1238
    9
    The court's ruling today essentially eliminates this discretionary option in foreign
    patent cases; the court makes no mention of the common nucleus of operative facts among
    Voda's United States and foreign patent issues, and does not review the district court's
    ruling on the ground of abuse of discretion. In eBay Inc. v. MercExchange L.L.C., 
    126 S. Ct. 1837
     (2006) the Court discouraged the carving out of an exception uniquely for patent
    cases, and required that the equitable discretion of the district court be as available in
    patent cases as in other cases. The panel majority strays from precedent, policy, and
    prudence, in ruling that the discretionary authority of the district court cannot or should not
    be exercised to resolve foreign patent disputes between parties properly before the court.
    My colleagues' reliance on the rules of supplemental jurisdiction does not support their
    restraint on this exercise of discretion.
    I respond to the several other justifications offered in the majority opinion, for they
    also are flawed:
    The Facts as Pled Support the District Court's Action
    The district court followed the Seventh Circuit's decision in Ortman, the closest
    precedent. The commonality of issues in the five countries of the Voda patents, including
    the United States, was before the district court. The accused catheter is the same in all five
    countries; it is manufactured by Cordis Corporation in a single plant, initially at Miami
    Lakes, Florida and now in Mexico. Cordis manages the Mexican plant and arranges for
    shipment to the Cordis companies in the five countries where infringement is charged, viz.,
    Cordis Corporation (US), Cordis S.A. (France), Cordis G.m.b.H (Germany), Cordis UK
    Limited, and Cordis in Canada. All of the Cordis companies are related to the Johnson &
    Johnson Company.
    05-1238
    10
    The patents in the five countries show that they are of common origin. A PCT
    (Patent Cooperation Treaty) application, based on the United States application, was filed
    in the Canadian and European Patent Offices. All of the patents have identical drawings,
    and the specifications are the same with additional text in the United States. The European
    patent application was filed and prosecuted in English, and the French and German patents
    are translations of the European patent. The British, French, and German patents have the
    specification and claims of the European patent grant.2
    Cordis says in its brief that there are differences among the patents, although no
    details were provided and differences are not apparent. But accepting this statement, I
    doubt that any differences are beyond the understanding of a United States court, with
    appropriate explanation if needed. Cordis also says that it intends to challenge the validity
    of all of the patents based on a reference that was not cited in any examination; it is not
    explained why a new reference cannot be considered as to not only the United States
    patent, but the foreign patents.
    My colleagues, supporting their ruling that the district court should not and can not in
    its discretion accept cases that raise issues of foreign patent validity and infringement, state
    that "more judicial resources could be consumed by the district court than the courts of the
    foreign patent grants." Maj. Op. at 26. This reason is unsupported by the pleaded facts.
    2     As for the majority's challenge to our knowledge of the content of the foreign-
    language patents, the record contains all five patents, and states, without challenge, that
    the German and French patents are translations of the European patent (the French patent
    is headed "Traduction de Brevet Europeen").
    05-1238
    11
    Nor should a court ignore the consumption of private as well as judicial resources in
    duplicative litigation between the same parties in five countries, in three languages, with
    five sets of lawyers and the other trappings and burdens of trial.
    My colleagues unfairly criticize the district court for not making any findings
    regarding the differences between the domestic and foreign patents, and equally unfairly
    criticize the absence of expert analysis of the foreign patent laws. It is surely inappropriate
    to criticize the judge for not making findings or taking evidence at the pleading stage. On a
    motion to amend the pleadings the court shall accept the well-pled allegations, Fed. R. Civ.
    P. 12(b)(6), and indeed no challenge to the premises has been presented.
    Discretionary authority is of broad scope, as is the judicial obligation to resolve
    disputes between litigants who are properly before the court. The district court's action
    reflects the "balance of conveniences," Piper Aircraft Co. v. Reyno, 
    454 U.S. 235
    , 255 n.23
    (1981), for the court could have considered the convenience to Dr. Voda, a citizen of
    Oklahoma, and balanced it against the convenience of multiple litigation in foreign
    countries. Cordis does not argue that it would be more "convenient" for it to litigate in five
    countries instead of one.
    Although a district court may decline to exercise its jurisdiction when it appears that
    the convenience of the parties and the court and the interests of justice are such that the
    action should be tried in another forum, 
    id. at 249-50
    , this determination is committed to the
    sound discretion of the district court. See, e.g., Leetsch v. Freedman, 
    260 F.3d 1100
    ,
    1102-03 (9th Cir. 2001) ("When we review a forum non conveniens determination, we give
    less deference to a foreign plaintiff's choice of a United States forum than to a domestic
    plaintiff's choice" and "[w]hether to dismiss an action on forum non conveniens grounds
    05-1238
    12
    require the district court to consider the availability of an adequate alternative forum, and
    then to consider whether several 'private' and 'public' interest factors favors dismissal.").
    Cordis has the burden of persuasion that the district court abused its discretion in choosing
    to receive the amended complaint. Our appellate role is to determine whether Cordis has
    met this burden and has shown that the district court's exercise of discretion is not
    sustainable in this case; it is an improper appellate ruling to remove that discretion.
    Complexity of Law or Fact
    I turn to the matter of complexity, for this aspect is also pressed in the panel
    majority's reasoning. My colleagues propose that in view of the complexities that may arise
    in connection with foreign patents, United States courts should not or can not exercise their
    discretion to enter the arena. Such a sweeping elimination of judicial authority contravenes
    the fundamentals of judicial responsibility, for judges cannot avoid cases because they may
    be complex. The complexity of patent law does not evict the district court from its
    discretionary authority.
    My colleagues appear to believe that each nation's patent on Dr. Voda's invention
    covers a different scope of subject matter. The proposition that the scope of counterpart
    patents, particularly those having identical claims, will usually vary significantly will come as
    a surprise and shock to the holders of literally millions of counterpart patents. In this case
    all five patents are of common origin and text, and the patents in Great Britain, France, and
    Germany are identical as granted by the European Patent Office. It is well recognized that
    most inventions receive consistent protection under the patent laws of the major industrial
    05-1238
    13
    nations.      The few areas of difference are well understood by practitioners.3            The
    international structure of patent laws, patent practitioners, and patent treaties, is bottomed
    on this commercial premise. International business depends on this expectation and
    reality.
    There is no assertion that the Voda catheter is so complicated as to test the nuances
    of comprehension and law. The panel majority states that its concern about "construing"
    different claims or even the same claims in different countries, and that expert testimony
    might be required. Expert testimony is not unusual in patent litigation, and experts on the
    meaning and scope of the claims in these countries are undoubtedly available if needed.
    See Fed. R. Civ. P. 44.1.4
    "The parties, therefore, carry the burden of proving foreign law; where they do not do
    so, we 'will ordinarily apply the forum's law.'" Ferrostaal, Inc. v. M/V Sea Phoenix, 
    447 F.3d 3
         Voda's catheter is a mechanical device, and does not raise new policy issues
    based on evolving areas of technology, such as the role of patents on computer software or
    genetic products.
    4      Rule 44.1. Determination of Foreign Law. A party who intends to raise an
    issue concerning the law of a foreign country shall give notice by pleadings or other
    reasonable written notice. The court, in determining foreign law, may consider any relevant
    material or source, including testimony, whether or not submitted by a party or admissible
    under the Federal Rules of Evidence. The court's determination shall be treated as a ruling
    on a question of law.
    05-1238
    14
    212, 216 (3rd Cir. 2006) (quoting Bel-Ray v. Chemrite Ltd., 
    181 F.3d 435
    , 440 (3d
    Cir.1999)); Banco de Credito Industrial, S.A. v. Tesoreria Gen., 
    990 F.2d 827
    , 836 (5th Cir.
    1993) (analyzing Spanish and French law and holding that "[w]hen the parties have failed
    to conclusively establish foreign law, a court is entitled to look to its own forum's law in
    order to fill in any gaps.").
    We do not know whether the accused Cordis device is a simple copy of the Voda
    invention or whether it embodies significant changes; that is, we do not know whether claim
    "construction," under any law, will be necessary. As for foreign languages, about which my
    colleagues also express concern, the Canadian and British patents are in English, as is the
    European patent of which the German and French patents are translations.                   The
    prosecution history in the European Patent Office is in English, as of course in Canada and
    the United States. It surely is not apparent that multiple litigation of the same issues in five
    countries and three languages is likely to be more economical of judicial time and litigation
    expense, and more likely to achieve a correct and just result, than resolving all of the issues
    before one judge in one case and one language. This aspect cannot serve to negate the
    district court's exercise of discretion to receive these issues.
    My colleagues also express concern about "jury confusion" when proving
    infringement of patents written in other languages and under foreign law. I take note that
    the Uniform Interstate and International Procedure Act, Article IV §4.03, states that "the
    court, not the jury, shall determine foreign law." See also Fed. R. Civ. P. 44.1. It need not
    be ignored that the extent to which the question of infringement is presented to a jury is
    diminished in the United States since the advent of the Markman practice; and whether a
    05-1238
    15
    corresponding foreign question under the laws of a country that does not have a jury
    system would avoid any Seventh Amendment obligation is not here at issue.
    The panel majority also states its concern that issues of foreign patents may not be
    correctly decided by a United States court. Undoubtedly this concern fits all of the areas in
    which courts have applied foreign law, and could be a factor in a district court's
    determination of whether to exercise jurisdiction in a particular case. However, such a
    discretionary determination is quite different from the panel majority's ruling that discretion
    should not be exercised to accept and decide foreign patent issues.
    My colleagues propose that permitting exercise of the district court's discretion to
    accept jurisdiction "could be fundamentally unfair to the alleged infringer." Indeed, fairness
    is an important aspect of discretionary rulings, and fairness to both sides must be
    considered. The panel majority does not explain its apparent balance of fairness in its
    holding that the alleged infringer is always more disadvantaged and can only be sued in the
    situs of the infringement. Such considerations would have evicted American courts in many
    areas of law, as in the representative cases cited earlier in this opinion. This concern does
    not warrant treating patent cases differently from all other causes of action.
    In this case, the district court was willing to take on the foreign issues. Perhaps the
    district court gave weight to the fact that the United States patent was being litigated
    anyway, on the same grounds and against the same device that is at issue in all five
    countries. Perhaps the court gave weight to equitable considerations, for they are always
    relevant to judicial discretion. None of the aspects here raised supports departing from the
    authority of courts to resolve disputes between parties that are properly before them,
    whether or not foreign law is involved. The fundamental question now presented is whether
    05-1238
    16
    a district court will be permitted to retain its judicial authority, or will this specific area be
    uniquely limited, whatever the position of the district court as to its discretion and its
    obligation.
    The Local Action Doctrine
    My colleagues also refer to the "local action" doctrine as barring the district court's
    jurisdiction of foreign patent issues. This "doctrine" arose in United States jurisprudence in
    the early days of the Republic, clarifying the jurisdiction of the state courts with respect to
    each other.    In Livingston v. Jefferson, 
    15 F. Cas. 660
     (C.C.D. Va. 1811), the court
    recognized the common law concept of local action and established that an action involving
    real property can be brought only within the state of the United States where the land is
    located. Such rulings have no relation to whether a United States court can resolve a dispute
    between persons personally before the tribunal by applying the law of a foreign country,
    whatever the issue. See generally 14D Charles Alan Wright, Arthur R. Miller & Edward H.
    Cooper, Federal Practice and Procedure: Jurisdiction and Related Matters 2d §3822, at 451-
    54 (2007). It is obscure how this "doctrine" supports my colleagues' ruling that a United
    States court cannot resolve disputes that raise questions of foreign patent law.
    The Act of State Doctrine
    The panel majority also invokes the "Act of State" doctrine as justification for barring
    the district court from choosing to decide the issues of Voda's foreign patents. The theory
    appears to be that the grant of a foreign patent is a governmental act of state, and thereby
    untouchable by a United States court. Thus the panel majority proposes that the district
    court's discretionary act would "prejudice the rights of other governments" to decide the
    05-1238
    17
    validity and enforceability of their patents. That proposition is unsupported. In Mannington
    Mills, Inc. v. Congoleum Corp., 
    595 F.2d 1287
    , 1293-94 (3rd Cir. 1979) the court rejected the
    theory that "the mere issuance of patents by a foreign power constitutes either an act of
    state, as that term has developed under case law, or an example of governments'
    compulsion." In Forbo-Giubiasco, 
    516 F. Supp. at
    1217 the court explained that "it cannot be
    said that a determination by an American court that a private company failed to present
    relevant information to a foreign patent office could interfere with our government's conduct
    of foreign affairs."
    In Banco National de Cuba v. Sabbatino, 
    376 U.S. 398
     (1963) the Court explained that
    "[t]he act of state doctrine in its traditional formulation precludes the courts of this country
    from inquiring into the validity of the public acts a recognized foreign sovereign power
    committed within its own territory," and that the doctrine precludes judicial determination of
    the legality of acts of foreign states within their own territories which might embarrass the
    executive department in its conduct of foreign affairs. 
    Id. at 427-49
    . Not every governmental
    action is an act of state, and not every ministerial activity carries the political and international
    implications of that usage.
    Whether a particular governmental action is properly viewed as an act of state has
    been explained in a variety of contexts; the common thread is whether the issue is one that is
    normally consigned to the executive branches, such that an international dispute is resolved
    by political negotiations between diplomats; or whether the issue is more suitable to the
    individual review that is given to litigants in judicial proceedings dealing with specific facts.
    See generally 
    12 A.L.R. Fed. 707
     (2006) ("Modern Status of the Act of State Doctrine"). The
    fundamental criterion is whether the governmental action is a significant public act or whether
    05-1238
    18
    it is a ministerial function, accompanied by whether the proposed judicial review is directed to
    the public interests of the nation as served by the governmental act, or is a private effort to
    enforce a private claim.
    Clearly, the grant of a patent is not an Act of State, whether done by the United States
    or by a foreign country. No support has been offered for so creative an application of
    international law; this "doctrine" provides no support for this court's removal of judicial
    discretion of United States courts to resolve a commercial dispute between private parties
    involving private patent rights. The Act of State doctrine is not relevant to judicial review of
    the Voda foreign patents; patent validity and infringement are legal and commercial issues,
    not acts of state. This doctrine does not create an exception that excludes foreign patents
    from access to dispute resolution in our courts.
    Enforcement Is Not An Issue
    There is no issue raised by either party concerning enforcement by a foreign court of
    the district court's potential decision concerning any of the Voda foreign patents. This case
    does not raise issues of comity, treaty, and diplomacy, when judgments are sought to be
    enforced in another country. The complexities of enforcement of foreign judgments, at which
    my colleagues hint, indeed serve to protect litigants from abusive procedures, and under the
    various protocols and treaties that relate to foreign judgments, a foreign court can refuse to
    accept a decision of another nation's tribunal. See Laker Airways Ltd. v. Sabena, Belgian
    World Airlines, 
    731 F.2d 909
    , 937-38 (D.C. Cir. 1984) ("No nation is under an unremitting
    obligation to enforce foreign interests which are fundamentally prejudicial to those of the
    domestic forum."); Motorola Credit Corp. v. Uzan, 
    388 F.3d 39
    , 60 (2d Cir. 2004) ("orders of
    foreign courts are not entitled to comity if the litigants who procure them have 'deliberately
    05-1238
    19
    courted legal impediments' to the enforcement of a federal court's orders") (citation omitted);
    Finanz AG Zurich v. Banco Economico S.A., 
    192 F.3d 240
    , 246 (2d Cir. 1999) (judicial
    proceedings may receive comity to the extent that the "foreign court had proper jurisdiction
    and enforcement does not prejudice rights of United States citizens or violate domestic public
    policy"). See generally Restatement (Third) of Foreign Relations Law of the United States
    §§481-82 (1987) (recognition and enforcement of foreign judgments and grounds for non-
    recognition of such judgments).
    The enforcement aspect was not raised by either party. The district court may have
    recognized that both Dr. Voda and Cordis Corporation, the manufacturer for all five countries,
    are within the district court's personal jurisdiction. In Forbo-Giubiasco, supra, the court
    explained that its findings with respect to the foreign patents were directed to the obligations
    of the parties to each other, and not to whether or how a foreign tribunal would view the
    decision.
    The issues and relationships herein reinforce the district court's exercise of discretion
    to accept the amended complaint, and further impugns this court's withdrawal of the district
    court's discretion as to foreign patents. There is no sound reason why speculative concerns
    of enforcement in foreign countries warrant depriving the district court of its discretion to
    resolve this dispute between these United States parties. While we do not know the extent to
    which the district court might find liability and impose constraints in this case, the answer to
    this dispute is not to bar the court from hearing it.
    The Role of Patent Treaties
    The panel majority proposes that it would violate the Paris Convention for the
    Protection of Industrial Property, the Patent Cooperation Treaty, and the TRIPS Agreement
    05-1238
    20
    of the World Trade Organization, if the United States were to consider the validity and
    infringement of Dr. Voda's foreign patents. None of these treaties prohibits resolution by a
    national court of private disputes that include foreign patent rights. The question is not as
    presented by the panel majority, whether any treaty imposes "an international duty" on a
    nation's courts to render decision concerning foreign patents. The question is whether any
    treaty prohibits a national court from resolving a dispute between entities under the personal
    jurisdiction of the court. No treaty bars such dispute resolution.
    Dispute Resolution is an Obligation of Courts
    The ruling of the panel majority departs not only from judicial precedent, but from
    judicial obligation. Although the court appears to concede that the district court may have
    "jurisdiction" to resolve the foreign aspects of this dispute, my colleagues hold that this
    authority cannot be exercised to resolve this dispute. This holding contravenes the judicial
    role. The district court has both the power and the obligation to resolve the dispute between
    the parties. See Cheney v. U.S. District Court for the District of Columbia, 
    542 U.S. 367
    , 370
    (2004) (referring to the district court's constitutional responsibility to resolve cases and
    controversies within its jurisdiction); Kirkpatrick & Co. v. Envt'l Tectronics Corp. Int'l, 
    493 U.S. 400
    , 409 (1990) ("Courts in the United States have the power, and ordinarily the obligation, to
    decide cases and controversies properly presented to them.").
    The majority postulates that discretion perhaps could be exercised "especially if
    circumstances change, such as if the United States were to enter into a new international
    patent treaty or if events during litigation alter a district court's conclusion regarding comity,
    judicial economy, convenience, or fairness." This is at best a confusing wrap-up to this
    important question, for no new international treaty is at hand, and the proposal that events
    05-1238
    21
    during litigation may change the conclusion is not helpful, for the question is whether this
    litigation will be conducted at all.
    The question here is simply whether, in a dispute between United States entities of
    whom the district court has personal jurisdiction, does the court have discretion to resolve
    aspects that concern foreign patents. The panel majority's conclusion that the court cannot
    exercise its discretion to do so is contrary to principle, practice, and judicial obligation.
    Comity, Harmonization, and the Future
    Comity is a complex concept of international law, and its generalization to evict United
    States courts from their dispute-resolution obligation is not supported on any theory of
    comity. See Hilton v. Guyot, 
    159 U.S. 113
    , 164 (1895) (defining comity as "neither of
    absolute obligation . . . nor of mere courtesy and good will" but "the recognition which one
    nation allows within its territory to the legislative, executive or judicial acts of another nation,
    having due regard both the international duty and convenience, and to the rights of its own
    citizens . . . who are under the protection of its laws."). Comity has no relevance to the need
    to apply foreign law and the obligation and authority to meet that need. In Piper Aircraft, 454
    U.S. at 260 n.29, the Court observed that "[t]he need to apply foreign law . . . alone is not
    sufficient to warrant dismissal when a balancing of all relevant factors shows that the
    plaintiff's chosen forum is appropriate."
    The panel majority raises the specter that foreign courts might adjudicate United
    States patent rights, proposing that if our courts are permitted to decide questions under
    foreign patent law, other countries will feel free to decide questions of United States patent
    law. Cordis too sounds the alarm, stating that creative litigants will choose exotic foreign
    forums to resolve complex patent issues, and that the district court's decision will open the
    05-1238
    22
    door to international chaos. I doubt that a United States district court is an exotic foreign
    forum; and it is not new for courts in other countries to apply the law of other nations when
    warranted. Courts in other countries have not refrained from applying foreign patent law,
    including United States law. A Japanese court recently applied the United States doctrine of
    equivalents in a suit between Japanese companies that included questions of infringement of
    United States patents, in K.K. Coral Corp. v. Marine Bio K.K., Case No. 1943(wa)/2002
    (Tokyo District Court, Oct. 16, 2003). All nations have recognized their obligation to provide
    a judicial forum to address disputes involving their citizens; no warrant has been shown to
    remove foreign patents from this purview.
    Proponents of patent "harmonization" point to the similarity of the policies that underlie
    patent law of all industrialized nations, and stress that for most technologies the same scope
    of practical protection is available to industrial development in all nations. It would be
    anomalous indeed for the United States now to rule that the courts cannot understand patent
    principles as applied in other nations.
    Preclusion and prejudgment are inappropriate and unnecessary. From my colleagues'
    extreme limitation and bar on the district court's exercise of discretion to receive and resolve
    foreign patent issues, I respectfully dissent.
