    PER CURIAM.
    The Patent Trial and Appeal Board (Board) affirmed
    the examiner’s rejections of claims 1–3 and 5–20 from
    Thomas Chuang’s patent application as obvious over a
    2                                            IN RE CHUANG
    combination of three references.    For the reasons dis-
    cussed below, we affirm.
    BACKGROUND
    Mr. Chuang filed his application on June 21, 2009 un-
    der the Patent Office’s Accelerated Examination pro-
    gram. 1 Following a final action issued by the Patent
    Office, Mr. Chuang appealed to the Board (then called the
    Board of Patent Appeals and Interferences). In response,
    the examiner reopened prosecution, but rejected all
    pending claims under 35 U.S.C. § 103, and rejected cer-
    tain claims as non-statutory subject matter under 35
    U.S.C. § 101. Mr. Chuang again appealed to the Board,
    which then issued a decision affirming the examiner’s
    rejections under 35 U.S.C. § 103, and, without the benefit
    of later-decided Alice Corp. v. CLS Bank Int’l, 
    134 S. Ct. 2347
    , 2358 (2014), the Board reversed the examiner’s
    rejections under 35 U.S.C. § 101. This appeal followed.
    We confine our review to the Section 103 issue. We have
    jurisdiction under 28 U.S.C. § 1295(a)(4).
    DISCUSSION
    We review the Board’s factual findings for substantial
    evidence and its legal conclusions de novo. In re Kotzab,
    
    217 F.3d 1365
    , 1369 (Fed. Cir. 2000). Obviousness is a
    question of law based on underlying facts. Graham v.
    John Deere Co., 
    383 U.S. 1
    , 17 (1966).
    1   As a condition of entry into the Accelerated Exam-
    ination Program, Mr. Chuang agreed not to separately
    argue the patentability of any dependent claims in any
    subsequent appeal. See Manual of Patent Examining
    Procedure (MPEP) § 708.02(a)(I), 9th ed., rev. 9 (Mar.
    2014). Mr. Chuang’s appeal of the rejections is thus
    focused on representative claims 1, 7, and 13, which are
    the independent claims.
    IN RE CHUANG                                             3
    REJECTION OF CLAIM 1
    Independent claim 1 recites a computer implemented
    method for managing rented downloaded content:
    A computer implemented method for managing
    rented downloaded content comprising:
    [a] presenting a user with a content descriptor as-
    sociated with a downloadable content down-
    loadable to the user available to rent at a rental
    price and purchase at an initial purchase price;
    [b] receiving a user rental request to rent the
    downloadable content at the rental price;
    [c] initiating downloading of the downloadable
    content to the user at a user computer responsive
    to receiving the user rental request, the down-
    loadable content including a use limitation com-
    prising an expiration date;
    [d] generating a user data structure comprising:
    [i] one or more content descriptors associ-
    ated with previously downloaded content
    rented by the user; and
    [ii] a status identifier for each content de-
    scriptor, the status identifier comprising
    the expiration date;
    [e] maintaining a database of user data structures
    corresponding to a plurality of users;
    [f] generating a previously downloaded content
    purchase price for a content descriptor associated
    with a previously downloaded content rented by
    the user;
    [g] providing the previously downloaded content
    purchase price to the user;
    4                                             IN RE CHUANG
    [h] receiving a user purchase request to purchase
    the previously downloaded content rented by the
    user and residing on the user computer; and
    [i] transmitting an update of the use limitation
    following receipt of the user purchase request, the
    update comprising a file update eliminating the
    expiration date included in the downloadable con-
    tent.
    Application, claim 1 (annotated).
    The examiner rejected claim 1 and dependent claims
    2–3 and 5–6 as obvious over the combination of three
    references: U.S. Patent publication no. 2004/0068451
    (Lenk), U.S. Patent no. 7,403,910 (Hastings), and U.S.
    Patent publication no. 2002/0032905 (Sherr). 2
    Lenk discloses an online system and method for rent-
    ing and purchasing electronic media, for example video
    games, wherein the media is mailed to the customer in
    physical discs. Lenk, abstract. Figure 31 illustrates an
    exemplary webpage, which displays a game product
    description page including selection buttons for “Rent it
    (36R),” and “Buy it (36b).” Any user can click on the “Buy
    it” button and purchase any game listed on the website
    for a corresponding “Buy it” price. 
    Id. at ¶¶
    81–82. In
    addition, Lenk discloses a monthly subscription rental
    model whereby a user is charged a monthly subscription
    fee. 
    Id. at ¶
    73. Subscribing members are permitted to
    take out a predetermined number of discs at any given
    time (e.g., no more than two games out at a time). 
    Id. If a
    member clicks on “Rent it” button when viewing a game,
    2   While not necessary to reject the claims, the
    examiner also cited a fourth reference (Ptasznik). Be-
    cause the claims are properly rejected under the combina-
    tion of Lenk, Hastings, and Sherr, we find it unnecessary
    to address Ptasznik.
    IN RE CHUANG                                              5
    that game is added to the member’s rental queue and
    subsequently delivered to that member. 
    Id. at ¶¶
    80–81.
    Under “Games You Have Out,” members have the option,
    at any time while a game is in their possession, to click
    the “Keep it” button and keep the game for a purchase
    price set by the service. 
    Id. at ¶
    106.
    Hastings likewise discloses a system for renting digi-
    tal audio and video products to customers using a sub-
    scription payment model. Hastings, col. 9, ll. 1–25.
    Similar to Lenk, Hastings teaches that customers can
    select movies, music, and videogames and prioritize them
    in a desired order within a rental queue. 
    Id. at col.
    8, ll.
    8–19. Hastings further discloses that the rental user can
    choose electronic delivery of the content by download over
    the Internet, or by shipment of physical media in the
    mail. 
    Id. at col.
    26, ll. 5–12. The download process is
    mediated by “a software feature or tool to manage the
    electronic transfer and relinquishment of the content
    product” with encryption provisions for “removal, change,
    or expiry of keys that unlock or enable the content to be
    used.” 
    Id. at col.
    26, ll. 15–17, col. 25, ll. 50–60. In the
    rental context, the tool may have the ability to delete
    content when the rental period for that content has ex-
    pired. 
    Id. at col.
    26, ll. 35–39.
    The third reference Sherr also discloses a rental sys-
    tem for video rental services. Sherr, ¶ 9. Unlike Lenk
    and Hastings, Sherr discloses a pay-as-you-go model that
    allows users to download movie files onto their computers
    using the Internet. 
    Id. Users send
    requests to rent
    digital video from an online catalog and upon payment,
    are able to download the video. 
    Id. Once a
    video is
    transmitted, it is viewable by a user for a specified period
    of time using an encryption key. 
    Id. at ¶¶
    88, 119, 122.
    The encryption key is disabled once the specified period of
    time expires and prohibits further replaying of the video.
    
    Id. at ¶¶
    121–22.
    6                                             IN RE CHUANG
    All three references disclose online video or video
    game rental services and, as the examiner found, describe
    business strategies that were old and well known in the
    art. In particular, the examiner noted that a skilled
    artisan would have recognized that the concepts of rent-
    ing media with the additional option of buying it, whether
    by mail, downloaded over the Internet, per title, or by a
    monthly subscription fee, were all old and well known.
    Individual features from each reference could thus be
    combined according to known methods to yield predictable
    results. For example, the examiner found that one of
    ordinary skill in the art would have “looked upon Has-
    tings and recognized that downloading media to be played
    on an electronic system is old and well known and would
    have been an obvious feature to be included with the
    system and method of Lenk,” which discloses delivery of
    rented media by mail. Examiner’s Answer dated Apr. 6,
    2011 (Answer), 12. Combining Lenk and Hastings would
    predictably provide “a more versatile media” as well as
    “providing a more streamlined process of allowing user’s
    [sic] to purchase media that they already have in their
    possession.” 
    Id. at 12-13.
    The examiner likewise found it
    would have been obvious to combine aspects of Sherr even
    though Sherr discloses a different payment model, be-
    cause that model was simply “an alternate business
    strategy that is old and well known in the art.” 
    Id. at 28.
    Ultimately, the nature of the problem to be solved—
    renting media to users—as well as the need to do so in an
    efficient and user-friendly way, would have led one of
    ordinary skill in the art to choose appropriate features
    from each reference to arrive at the claimed invention.
    In particular, the examiner found that Lenk teaches
    most of the limitations of claim 1, including presenting
    the content for rent or purchase, receiving a rental re-
    quest for the content, delivering the content, providing
    the user a purchase price for the previously rented con-
    tent in the user’s possession, receiving a purchase request
    IN RE CHUANG                                               7
    for the content, and updating the database to reflect the
    sale. The examiner also found that the claimed “rental
    price,” under its broadest reasonable interpretation,
    encompasses the monthly rental scheme disclosed in
    Lenk. The examiner acknowledged that the combination
    of Lenk and Hastings fails to disclose a use limitation and
    a status identifier, the limitation and identifier each
    comprising an expiration date. However, Sherr disclosed
    those limitations by teaching media that is encrypted and
    unlocked using an encryption key that expires once a
    specified period of time passes.
    The Board reviewed, agreed with, and affirmed the
    examiner’s obviousness rejections. Accordingly, the Board
    rejected Mr. Chuang’s argument that the claimed “rental
    price” is not met by Lenk’s subscription plan model. The
    Board agreed with the examiner that the term encom-
    passes monthly rental schemes, finding that “each rental
    media in the Lenk system has an associated price, which
    is the monthly subscription fee.” The Board also rejected
    Mr. Chuang’s argument that Lenk teaches away from the
    use of an expiration date because there are no “due dates”
    in the monthly subscription plan. The Board found that
    while Lenk teaches an alternative design, Mr. Chuang
    failed to show that Lenk criticizes, discredits, or otherwise
    discourages the claimed solution.
    Mr. Chuang advances here essentially the same ar-
    guments he raised on appeal to the Board. First, he
    contends that the Board erred in affirming the examiner’s
    determination that Lenk discloses the claimed “rental
    price” of clause [a]. Specifically, Mr. Chuang contends
    that the Board failed to construe the term or in the alter-
    native, incorrectly construed the term.
    We find that the Board, in adopting the examiner’s
    analysis, addressed the construction of the term ade-
    quately enough to permit judicial review. See, e.g., In re
    Hyatt, 
    211 F.3d 1367
    , 1371 (Fed. Cir. 2000). With respect
    8                                             IN RE CHUANG
    to “rental price,” the examiner found that the prior art
    does “have an associated rental fee for renting media
    online[.]” Answer at 27. This statement implicitly con-
    strues the “rental price” limitation, under its broadest
    reasonable interpretation, to mean “an associated rental
    fee for renting media online.”
    Here, Mr. Chuang has not provided a persuasive rea-
    son, e.g., disclaimer or lexicography, for us to depart from
    the examiner’s construction (adopted by the Board). We
    also note that his proposed construction is inconsistent
    with other parts of the specification, which discloses a
    DVD rental embodiment where users pay a monthly fee
    which allows the user to rent as many DVDs as desired.
    Under the agency’s reasonable construction, there is no
    dispute that Lenk’s monthly fee for renting media disclos-
    es the “rental price” as claimed. 3
    Next, Mr. Chuang contends that Lenk is not properly
    combined with Sherr to teach the term “expiration date”
    in limitations [c] and [d] of claim 1. Mr. Chuang does not
    dispute that Sherr discloses this limitation. However, he
    contends that Lenk’s disclosure of a monthly subscription
    system teaches away from use of expiration dates as
    claimed in his invention. Specifically, because Lenk
    teaches that members can rent their games for any length
    of time and emphasizes the absence of due dates as a
    benefit of its subscription model, it teaches away using
    expiration dates.
    3    Moreover, it is undisputed that the prior art dis-
    closes the claimed “rental price” even under Mr. Chuang’s
    narrow conception of the term. As the examiner found,
    Sherr discloses the old and well-known method of allow-
    ing users to rent a particular movie for a predetermined
    time period for a specified payment. Answer at 13; Sherr,
    Fig. 9; 
    id. at ¶
    9.
    IN RE CHUANG                                               9
    We disagree. There is substantial evidence to support
    the Board’s finding that Lenk does not teach away from
    the claimed invention. The fact that the two references
    teach different payment models for how to rent videos
    does not mean that a person of ordinary skill in the art
    would have been discouraged from combining different
    features from the two disclosures, including the well-
    known aspect of using expiration dates on rental media.
    “[I]t is not necessary that the inventions of the references
    be physically combinable to render obvious the invention
    under review.” In re Sneed, 
    710 F.2d 1544
    , 1550 (Fed.
    Cir. 1983); see also In re Fulton, 
    391 F.3d 1195
    , 1201 (Fed.
    Cir. 2004) (“The prior art’s mere disclosure of more than
    one alternative does not constitute a teaching away from
    any of these alternatives because such disclosure does not
    criticize, discredit, or otherwise discourage the [claimed]
    solution . . . .”). Rather, the relevant inquiry is “what the
    combined teachings of the references would have suggest-
    ed to those of ordinary skill in the art.” In re Keller, 
    642 F.2d 413
    , 425 (C.C.P.A. 1981).
    In adopting the examiner’s rejections, the Board rea-
    sonably found that both references are directed to the
    same field of endeavor—distribution and rental of media.
    It was further reasonable for the Board to find that using
    an expiration date with the downloaded rented media of
    Lenk (as modified in view of Hastings) was no more than
    a combination of familiar elements in a known way to
    yield predictable results. As the references teach old and
    well-known concepts for renting media, taking a well-
    established feature of one and incorporating it into the
    other would have been obvious. See, e.g., Lenk, ¶ 69
    (generally stating that its invention may be “applied to
    rental and sales of electronic entertainment items.”)] Mr.
    Chuang is unable to point to any passage in Lenk that
    criticizes or otherwise discourages the use of expiration
    dates in a rental system using a subscription payment
    model. Indeed, the examiner found that Hastings, which
    10                                             IN RE CHUANG
    like Lenk teaches a subscription model, teaches deleting
    downloaded media after the rental time has expired.
    We thus find that the Board did not err in upholding
    the examiner’s rejection of claim 1.
    REJECTION OF CLAIM 7
    Mr. Chuang relies on the same arguments presented
    for claim 1 in appealing the rejection of claim 7. We reject
    these arguments for the same reasons as set forth for
    claim 1 and find that the Board did not err in upholding
    the rejection of claim 7.
    REJECTION OF CLAIM 13
    Claim 13 is similar to claim 1 and, relevant here, re-
    quires a step of providing to the user a user data struc-
    ture comprising, inter alia, “a rent again selector for each
    content descriptor . . . , the rent again selector associated
    with a previously downloaded content rent again price
    . . . .” Mr. Chuang contends that the Board erred in
    finding that a “rent again selector” and a “rent again
    price” would have been obvious over the prior art. He
    does not dispute that the examiner properly found these
    limitations are disclosed in Sherr. Rather, he again
    argues that the teachings of Lenk and Sherr are incom-
    patible because their respective media rental schemes are
    incongruous.
    We disagree and find the Board provided substantial
    evidence of motivation for one of ordinary skill to combine
    the teachings in the references to enable re-renting of
    media. Through adopting the examiner’s Answer, the
    Board reasonably found that one of ordinary skill in the
    art looking at Lenk’s “Keep it” button would have under-
    stood there was a motivation to provide shortcuts to allow
    users to obtain items as quickly as possible. The same
    motivation would have led one of ordinary skill in the art
    to combine the attributes of Lenk with Sherr’s teaching of
    re-renting media, with a “rent again” button “to provide
    IN RE CHUANG                                              11
    shortcuts to [allow users to] obtain an item as quickly as
    possible . . . since it allows for better customer satisfac-
    tion/service.” Answer at 32–33. See In re 
    Keller, 642 F.2d at 425
    . And as the examiner reasonably found, doing so
    would have been a combination of familiar elements in a
    known way to yield predictable results.
    Mr. Chuang also contends that the prior art does not
    disclose claim 13’s requirement of the step of receiving a
    user request to re-rent previously rented content that is
    “residing on the user computer.”         Contrary to Mr.
    Chuang’s arguments, as the Board and examiner found,
    Sherr teaches that users can pay for unlock codes to “re-
    rent the downloaded media.” See Answer at 29 (citing
    Sherr, ¶¶ 88, 119, 122). Finally, Mr. Chuang relies on the
    same arguments he presented for claim 1 as additional
    grounds for appealing the rejection of claim 13. We reject
    these arguments for the same reasons as set forth for
    claim 
    1, supra
    .
    We thus find the Board did not err in upholding the
    examiner’s rejection of claim 13.
    CONCLUSION
    For the foregoing reasons, we conclude that the Board
    properly affirmed the examiner’s rejection of representa-
    tive claims 1, 7, and 13 as obvious over Lenk, Hastings,
    and Sherr. We have considered Mr. Chuang’s remaining
    arguments and find them without merit. We thus affirm
    the rejections of claims 1–3 and 5–20.
    AFFIRMED
