    Before LOURIE, O’MALLEY, and REYNA, Circuit Judges.
    LOURIE, Circuit Judge.
    Nuance Communications, Inc. (“Nuance”) appeals from
    two final written decisions of the U.S. Patent and Trade-
    mark Office Patent Trial and Appeal Board (“the Board”)
    holding claims 8 and 13 of U.S. Patent 8,117,034 (“the ’034
    patent”) and claims 9–11 of U.S. Patent 6,999,933 (“the
    ’933 patent”) unpatentable as obvious. See MModal LLC v.
    Nuance Commc’ns, Inc., No. IPR2018-01431 (P.T.A.B. Apr.
    3, 2020), J.A. 134–96; MModal LLC v. Nuance Commc’ns,
    Inc., No. IPR2018-01435 (P.T.A.B. Apr. 21, 2020), J.A. 197–
    266. For the reasons detailed below, we affirm.
    BACKGROUND
    Nuance owns the ’034 and ’933 patents, which are
    directed to systems and methods for correcting text
    generated by automatic speech recognition technology
    (“ASR”). We begin with a brief background of the
    technology. ASR converts spoken words into text. J.A.
    2702. Specifically, audio files with speech recordings are
    “distribute[d]” to computers with ASR. ’933 patent col. 1
    Case: 20-1549     Document: 63      Page: 3     Filed: 03/10/2021
    NUANCE COMMUNICATIONS, INC.     v. MMODAL LLC                 3
    ll. 23–28. 1 Using ASR, the computers generate a written
    transcript of the audio file. Id. col. 1 ll. 29–39.
    The patents describe that ASR can be error-prone,
    requiring human editors (“transcriptionists”) to make
    corrections to the converted text. Id. col. 1 ll. 4–9; see also
    J.A. 1441 col. 1 ll. 35–52. In order to correct the generated
    text, transcriptionists typically listen to an audio file of the
    words while an “audio cursor” follows along in the
    transcript. ’933 patent col. 1 ll. 40–50. The audio cursor
    visually indicates the word in the transcript that
    corresponds to the word that has just been spoken in the
    audio file. Id. This method is referred to as “synchronous
    playback mode.” Id. Although synchronous playback mode
    made it easier for transcriptionists to review the transcript,
    it had a specific disadvantage: whenever transcriptionists
    would spot an error, they would need to stop the playback
    of the audio, correct the error, and only then resume the
    audio. Id. col. 1 ll. 51–58. The patents explain that the
    delay could be time consuming. Id. col. 2 ll. 7–13.
    The patents purport to improve upon the
    disadvantages of synchronous playback mode. Unlike
    previous systems, which disclosed only the use of an audio
    cursor, the patents disclose the use of a synchronous
    playback mode that includes an audio cursor and a text
    cursor. Id. col. 3 ll. 29–52. Consequently, transcriptionists
    can make a text correction with the text cursor while the
    audio cursor continues to move through the text in time
    with the audio. Id. col. 6 ll. 35–42. Importantly,
    transcriptionists need not stop the audio playback when
    making a text correction, unlike prior systems. Id. col. 3 ll.
    35–43. The patents further describe that transcriptionists
    can synchronize the text cursor with the audio cursor or the
    1   Because the specifications of the patent are sub-
    stantially similar, we cite only the ’933 patent unless oth-
    erwise indicated.

    audio cursor with the text cursor. Id. col. 3 ll. 53–66, col. 8
    ll. 1–7. All of the challenged claims recite an audio cursor
    and a text cursor.
    Claim 8 of the ’034 patent reads as follows:
    8. A method of assisting in correcting text
    information recognized by a speech recognition
    device from speech information, the method
    comprising:
    receiving the speech information, the text
    information      recognized    from    the   speech
    information, and link information that associates
    portions of the text information with portions of the
    speech information from which the portions of the
    text information were recognized by the speech
    recognition device;
    providing an audio cursor for display during
    acoustic playback of the speech information, the
    audio cursor highlighting portions of the text
    information synchronous with the playback of the
    speech information according to associations
    provided by the link information such that, when
    displayed to the user, the audio cursor highlights
    the portions of the text information as the
    associated portions of the speech information are
    being acoustically played back; and
    providing a text cursor for display to facilitate
    editing the text information, the text cursor
    indicating a position in the text information where
    at least one edit will be performed upon receiving
    editing information entered by the user; and
    automatically synchronizing the text cursor and
    the    audio   cursor,   wherein      automatically
    synchronizing the text cursor and the audio cursor
    comprises automatically positioning the text cursor
    at a predetermined position relative to a location of
    Case: 20-1549      Document: 63      Page: 5   Filed: 03/10/2021
    NUANCE COMMUNICATIONS, INC.      v. MMODAL LLC              5
    the audio cursor and automatically moving the
    location of the text cursor synchronous with the
    movement of the audio cursor during the acoustic
    playback until an editing operation is performed.
    ’034 Patent col. 9 l. 43–col. 10 l. 6.
    Dependent claim 13 recites:
    13. The method of claim 8, wherein automatically
    synchronizing includes continuously automatically
    synchronizing the text cursor and the audio cursor
    when a continuous synchronous playback mode is
    activated, the method further comprising:
    deactivating      continuously        automatically
    synchronizing upon receiving at least one first
    keyboard input from the user, the deactivating
    including uncoupling the text cursor from the audio
    cursor; and
    activating the continuous synchronous playback
    mode upon receiving at least one second keyboard
    input from the user to resume continuously
    automatically synchronizing the text cursor and
    the audio cursor.
    Id. col. 10 ll. 33–45.
    Claim 9 of the ’933 patent reads as follows:
    9. A correction method (16) for the correction of
    incorrect words in text information (ETI)
    recognized by a speech recognition device (1) from
    speech information (SD), in which the following
    method steps are executed:
    reception of the speech information (SD), the
    associated recognized text information (ETI) and
    link information (LI), which marks the part of the
    speech information (SD) at which the word was
    Case: 20-1549      Document: 63      Page: 6   Filed: 03/10/2021
    6               NUANCE COMMUNICATIONS, INC.     v. MMODAL LLC
    recognized by the speech recognition device (1) for
    each word of the recognized text information (ETI);
    allowing a synchronous playback mode, in which,
    during the acoustic playback of the speech
    information (SD) the word of the recognized text
    information (ETI), which word is marked by the
    link information (LI) for the speech information
    (SD) just played back is marked synchronously,
    while the word just marked features the position of
    an audio cursor (AC);
    editing of the incorrect word with a text cursor (TC)
    according to editing information (EI) entered by a
    user, the editing of the incorrect word being
    possible with the synchronous playback mode
    activated in the correction device (10).
    ’933 patent col. 9 l. 44–col. 10 l. 20.
    Claim 10, which depends from claim 9, recites that the
    “text cursor (TC) is synchronized with the audio cursor
    (AC) or the audio cursor (AC) is synchronized with the text
    cursor (TC) depending on the editing information entered
    (EI).” Id. col. 10 ll. 21–25. Claim 11, which also depends
    from claim 9, requires that the “cursors . . . are
    synchronized by manually actuating at least one key.” Id.
    col. 10 ll. 26–28.
    This appeal primarily centers on two elements of the
    claims: (1) the use of a text cursor to edit incorrect words
    in a transcript, and (2) the use of an audio cursor to visually
    indicate the word in the transcript that corresponds to the
    Case: 20-1549     Document: 63      Page: 7    Filed: 03/10/2021
    NUANCE COMMUNICATIONS, INC.     v. MMODAL LLC                7
    word that has just been spoken in the audio file.          See
    Appellant’s Br. 46. Both cursors are shown below.
    ʼ034 Patent, Portion of Fig. 1 (annotated).
    MModal LLC (“MModal”) filed petitions for inter partes
    review of claims 8 and 13 of the ’034 patent and claims 9–
    11 of the ’933 patent. In both petitions, MModal asserted
    that the claims would have been obvious over U.S. Patent
    6,360,237 (“Schulz”), or Schulz in view of U.S. Patent
    Publication 2002/0095291 (“Sumner”).
    Schulz discloses systems and methods for editing text
    generated by ASR while the recorded audio is played back.
    Like the patents, Schulz explains that prior art methods of
    correcting ASR transcription errors were time consuming
    because they required the transcriptionists to stop the
    audio playback before correcting any errors. J.A. 1441 at
    col. 2 ll. 6–8, 16–24. In order to improve upon this “slow
    process,” Schulz describes a “playback edit mode” that
    allows transcriptionists to edit a transcript without
    stopping the audio recording. J.A. 1441 at col. 2 ll. 23–24;
    J.A. 1443 at col. 5 l. 54–col. 6 l. 3.
    Schulz discusses multiple approaches for defining the
    location of an edit within the transcript.             In one
    embodiment, one cursor visually indicates both the location
    at which a text edit will occur and the position of the word
    just spoken in the audio playback. J.A. 1440 at Figs. 4a–
    4b; J.A. 1444 at col. 7 ll. 29–32; J.A. 1446 at col. 11 ll. 31–
    36. For example, “[i]n FIG. 4a, [shown below] the cursor is
    Case: 20-1549     Document: 63     Page: 8    Filed: 03/10/2021
    8              NUANCE COMMUNICATIONS, INC.     v. MMODAL LLC
    underneath the word ‘accident’ at the same time that this
    word is being spoken on the audio recording. . . . The period
    edit function key is then depressed. FIG. 4b shows the
    insertion of a period 66 immediately after the word
    ‘accident.’” J.A. 1446 at col. 11 ll. 31–36.
    Alternatively, Schulz discloses a second embodiment
    that includes a “reaction time variable” to improve the
    editing process. Here, Schulz recognizes that a user may
    struggle to press the appropriate key quickly enough to
    trigger an edit “while the desired word is underscored by
    the cursor.” J.A. 1446 at col. 11 ll. 49–54. The reaction
    time variable can thus “compensate for the
    transcriptionist’s reaction time by adjusting the location of
    an editing function by the reaction time.” Id. at col. 11 ll.
    63–65. In this embodiment, there are two separate
    locations: (1) an audio cursor that visually indicates the
    word in the transcript that corresponds to the word that
    has just been spoken in the audio file (“cursor 60”), and (2)
    a text insertion point that is separated from cursor 60 by a
    period of time and determines the location that text edits
    will be made (“insertion point 61”). Id. at col. 11 l. 49–col.
    12 l. 55. See also Appellee’s Br. 39. Cursor 60 is denoted
    by a visual indicator. Important to this appeal, unlike
    cursor 60, insertion point 61 is not displayed visually
    (although insertion point 61 is denoted by a triangle in Fig.
    5a, the Board found, and the parties do not dispute, that it
    is technically “not displayed visually”). J.A. 169; J.A. 241.
    Figure 5a, shown below, illustrates this embodiment.
    Schulz explains that “cursor 60 is aligned under the word
    ‘accident’ as it is being reproduced in audio.” J.A. 1443 at
    col. 6 ll. 30–35. If a reaction time variable is employed
    (such as 250 milliseconds), when the user presses the edit
    function key at time T0, an edit will be performed on the
    word “automobile” (the word that was marked by the
    cursor 60 at a time 250 milliseconds before time T0 and is
    represented by insertion point 61). J.A. 1446 at col. 12 ll.
    22–32.
    Case: 20-1549     Document: 63     Page: 9    Filed: 03/10/2021
    NUANCE COMMUNICATIONS, INC.    v. MMODAL LLC                9
    Schulz also discloses a “standard text editor mode,” in
    which playback of the audio file is stopped and the
    transcriptionists can use a cursor to edit the text. J.A. 1443
    at col. 5 ll. 35–44; J.A. 1447 at col. 13 ll. 21–27.
    Sumner discloses two cursors with two different
    functions for use with ASR: (1) an insertion cursor, to
    “denote the location where new text will be inserted within
    a document,” and (2) a correction cursor, which marks the
    last location where a correction to the text was made. J.A.
    1538–40 ¶¶ 8, 14, 24–25.
    Before analyzing whether the claims would have been
    obvious, the Board engaged in claim construction. It
    determined that “using a single visual indication on a
    display to mark the position of both the audio cursor and
    the text cursor” falls within the scope of the claims. J.A.
    143; J.A. 207 (emphasis added). Subsequently, the Board
    concluded that the claims are unpatentable as obvious
    under two separate grounds. Under the first ground,
    pursuant to its claim construction, the Board determined
    that the claims would have been obvious over Schulz.
    Specifically, the Board found that the single displayed
    cursor in Schulz, as exemplified in Figures 4a–b, satisfies
    both the “audio cursor” and “text cursor” limitations of the
    claims. J.A. 165–67; J.A. 228–30. Under the second
    Case: 20-1549    Document: 63      Page: 10    Filed: 03/10/2021
    10             NUANCE COMMUNICATIONS, INC.     v. MMODAL LLC
    ground, the Board concluded that, even if contrary to its
    construction, the claims require separate visual indicators
    for each cursor, they still would have been obvious over
    Schulz’s reaction time embodiment (Figures 5a–b).
    Specifically, it determined that it would have been obvious
    to combine a “visual indicator” at the targeted insertion
    point 61 (to satisfy the text cursor limitation) with the
    audio cursor 60, in view of Schulz, or Schulz and Sumner.
    J.A. 169; J.A. 241.
    Nuance appealed to this court. We have jurisdiction
    pursuant to 
    28 U.S.C. § 1295
    (a)(4)(A).
    DISCUSSION
    We review the Board’s legal determinations de novo, In
    re Elsner, 
    381 F.3d 1125
    , 1127 (Fed. Cir. 2004) (citing In re
    Kollar, 
    286 F.3d 1326
    , 1329 (Fed. Cir. 2002), and its fact
    findings for substantial evidence, In re Gartside, 
    203 F.3d 1305
    , 1316 (Fed. Cir. 2000). A finding is supported by sub-
    stantial evidence if a reasonable mind might accept the ev-
    idence as adequate to support the finding. Consol. Edison
    Co. v. N.L.R.B., 
    305 U.S. 197
    , 229 (1938).
    Obviousness is a question of law, supported by under-
    lying fact questions. In re Baxter Int’l, Inc., 
    678 F.3d 1357
    ,
    1361 (Fed. Cir. 2012). In evaluating obviousness, we con-
    sider the scope and content of the prior art, differences be-
    tween the prior art and the claims at issue, the level of
    ordinary skill in the pertinent art, and any relevant sec-
    ondary considerations. Graham v. John Deere Co., 
    383 U.S. 1
    , 17–18 (1966).
    Nuance asserts that the Board erred in concluding that
    the prior art renders obvious the use of a text cursor in
    combination with an audio cursor, as required by the
    claims. We first address Nuance’s arguments regarding
    independent claims 8 and 9 and then address Nuance’s
    arguments regarding dependent claims 10 and 13.
    Case: 20-1549    Document: 63         Page: 11      Filed: 03/10/2021
    NUANCE COMMUNICATIONS, INC.        v. MMODAL LLC               11
    I
    We turn first to Nuance’s argument that the Board
    erred in concluding that claims 8 and 9 are unpatentable
    as obvious. Nuance contends that the Board’s second
    obviousness ground, which was based on Schulz’s reaction
    time embodiment, was erroneous. Specifically, Nuance
    asserts that the Board erred in finding that it would have
    been obvious for a person of skill to combine a (1) “visual
    indicator” at insertion point 61 with (2) the audio cursor 60.
    According to Nuance, the Board provided “no . . . reasons”
    as to why a person of skill in the art would be motivated to
    modify Schulz in this manner. Appellant’s Br. 53. MModal
    responds that the Board’s analysis was supported by
    substantial evidence. According to MModal, a person of
    ordinary skill would have been motivated to add a visual
    indicator at insertion point 61 in order to view the location
    where text edits would occur.
    We agree with MModal that the Board’s determination
    was supported by substantial evidence. First, the Board
    found that “the use of, and the benefits of displaying, each
    type of cursor—an audio cursor and a text cursor—were
    well known in the art.” J.A. 169; see also J.A. 241. As the
    Board observed, the patent specifications themselves
    disclose that it was well known in the art to use an audio
    cursor to follow the words being played back and to use a
    text cursor to make corrections to the text. See J.A. 169
    (citing ’034 patent col. 1 ll. 28–56); see also J.A. 241. Given
    these benefits, the Board reasonably found that a person of
    ordinary skill would have been motivated to add a visual
    indicator at insertion point 61 for use with Schulz’s audio
    cursor 60. The Board elaborated that doing so would allow
    a person to simultaneously (1) confirm the “precise
    position” where edits would occur with a text cursor at
    insertion point 61, and (2) observe the text being spoken in
    the audio playback with the audio cursor 60. J.A. 172–174;
    J.A. 245–247. Indeed, the Board pointed out that not
    displaying a visual indicator at insertion point 61 could
    Case: 20-1549    Document: 63      Page: 12     Filed: 03/10/2021
    12              NUANCE COMMUNICATIONS, INC.     v. MMODAL LLC
    create confusion as to where the corrections would be
    made. J.A. 172 (citing expert testimony); J.A. 245. The
    Board’s determination was further supported by Sumner,
    which discloses the advantages of displaying cursors
    relating to two different, but relevant functions at the same
    time. 
    Id.
     Moreover, implementing such a modification
    would have taken only routine skill. For example, the
    Board credited MModal’s argument, based on expert
    testimony, that “it was well-known for text editors, such as
    Microsoft Word, to visually display a text cursor . . . .” J.A.
    169; J.A. 241–42.
    Nuance makes several arguments as to why the
    Board’s determination should be reversed, all
    unconvincing. First, Nuance argues that Sumner cannot
    support the Board’s second obviousness determination
    because its two cursors do not function as an audio cursor
    and a text cursor. Appellant’s Br. 53.
    Nuance’s argument misses the mark. The Board
    acknowledged that, strictly speaking, Sumner’s cursors do
    not correspond to the audio cursor and text cursor of the
    claims. See J.A. 173–75; J.A. 246–48. However, the Board
    did not rely on Sumner for that purpose. Rather, the Board
    relied on Sumner’s disclosure that it would be beneficial to
    simultaneously display two cursors with different
    functions. 
    Id.
     The Board further found that a person of
    ordinary skill would have been motivated to implement
    that teaching in order to modify Schulz. 
    Id.
    Second, Nuance argues that the Board improperly
    “requir[ed]” it to prove that the specifications describe the
    inventive aspects of the claims, namely, the simultaneous
    display of two separate cursors. Appellant’s Br. 51–52.
    According to Nuance, the specifications “did not need to
    emphasize the visual nature of the cursors because” a
    person of ordinary skill in the art “reviewing the
    specifications would have understood . . . the advantages
    that the two cursors would provide.”             
    Id. at 52
    .

    NUANCE COMMUNICATIONS, INC.    v. MMODAL LLC               13
    Consequently, Nuance contends it was improper for the
    Board to require such a showing in order to conclude that
    the claims are nonobvious. 
    Id.
    We disagree with Nuance’s interpretation of the
    Board’s analysis. Contrary to Nuance’s assertion, at no
    point did the Board indicate that its obviousness
    determination hinged on the specifications’ disclosure that
    the claimed subject matter is inventive. Rather, the Board
    simply examined the specifications and found support for
    its obviousness determination. It was not improper for the
    Board to review the specifications when analyzing whether
    the claims would have been obvious. Moreover, the Board’s
    analysis was further supported by a variety of other
    evidence, including prior art and expert testimony. See,
    e.g., J.A. 169; J.A. 241–42.
    Third, Nuance asserts that insertion point 61 cannot
    be a “different cursor from cursor 60” as it is “simply the
    position of cursor 60 at a different, earlier point in time.”
    Appellant’s Br. 49. We disagree. Although insertion point
    61 denotes the location of cursor 60 at an earlier point in
    time, it still performs a separate and distinct function,
    namely, denoting where edits will occur. See J.A. 169.
    Indeed, for that very reason, in Schulz, it is denoted by a
    different number (61) from cursor 60. 2
    2   Nuance also contends that the Board should have
    construed cursor to mean a “moveable indicator on a
    display screen.” Appellant’s Br. 35, 52–53. According to
    Nuance, under its construction, insertion point 61 cannot
    be a cursor because it doesn’t visibly indicate the text
    location. However, that amounts to an argument that
    because insertion point 61 is not visible, it would not have
    been obvious to make it visible. As discussed, the Board
    already found that it would have been obvious to make
    insertion point 61 visible.

    In sum, the Board reasonably found that a person of
    ordinary skill “would have wanted, and known how, to see
    where . . . text edits would occur by providing a visual
    indicator” to show the position of insertion point 61. J.A.
    173; J.A. 245. Because the Board’s second obviousness
    ground was supported by substantial evidence, we need not
    reach Nuance’s arguments regarding the Board’s first
    obviousness ground (Schulz Figures 4a–b), which did not
    include a reaction time.
    II
    We turn next to Nuance’s arguments that the Board
    erred in concluding that dependent claims 10 and 13 are
    unpatentable as obvious. First, Nuance asserts that the
    Board did not explicitly determine that claims 10 and 13
    would have been obvious under its second obviousness
    ground (based on Schulz’s reaction time embodiment).
    Rather, Nuance contends that the Board applied its second
    obviousness ground only to independent claims 8 and 9.
    Second, Nuance argues that claims 10 and 13 are not
    unpatentable as obvious, even under the Board’s second
    obviousness ground. We address each argument in turn.
    A
    As an initial matter, the Board indicated that it
    analyzed the dependent claims under the first and second
    obviousness grounds. For example, when addressing
    Nuance’s arguments regarding claim 10, the Board
    clarified that it was incorporating its entire analysis for
    claim 9, including its second obviousness ground. See J.A.
    257 (noting with respect to claim 10 that “[f]or reasons we
    discussed for claim 9 . . . we are persuaded [MModal] has
    shown Schulz, alone or in combination with Sumner,
    teaches two distinct cursors”). Similarly, the Board stated
    that its analysis of claim 13 incorporates its analysis of
    claim 8, at least in part. See J.A. 185 (reiterating that “all
    of” claim 8’s limitations would have been obvious “[f]or the
    reasons explained above in Section III.B.3.a” and then
    Case: 20-1549    Document: 63      Page: 15     Filed: 03/10/2021
    NUANCE COMMUNICATIONS, INC.    v. MMODAL LLC               15
    explaining why “the additional limitations recited in claim
    13” would also have been obvious in view of Schulz)
    (emphasis added).
    To the extent that the Board did not explicitly state
    whether it was analyzing the claims under the second
    obviousness ground, any such ambiguity was harmless.
    First, the logic of the Board’s determination would have
    been substantially the same under either obviousness
    ground, as will be further explained below. Second, the
    dependent claims only add minor limitations to the
    independent claims. For example, independent claim 9
    recites use of a text cursor and an audio cursor. See ’933
    patent col. 9 l. 44–col. 10 l. 20. Claim 10, which depends
    from claim 9, recites, in relevant part, that the “text cursor
    (TC) is synchronized with the audio cursor (AC) or the
    audio cursor (AC) is synchronized with the text cursor (TC)
    depending on the editing information entered (EI).” 
    Id.
     col.
    10 ll. 21–25. Indeed, before the Board, Nuance did not
    present arguments for claim 10 beyond those already
    raised for claim 9. See J.A. 257. Additionally, claim 10’s
    synchronization limitation is similar to independent claim
    8’s limitation that requires “automatically synchronizing
    the text cursor and the audio cursor,” which the Board
    explicitly found obvious under its second ground. Compare
    ’933 patent col. 10 ll. 21–25, with ’034 patent col. 9 ll. 66–
    67; J.A. 173–77. Similarly, claim 13 recites, in relevant
    part, “uncoupling the text cursor from the audio cursor.”
    ’034 patent col. 10 ll. 40–41.
    B
    We now turn to Nuance’s argument that claims 10 and
    13 are not unpatentable as obvious, even under the Board’s
    second obviousness ground. With respect to claim 10,
    Nuance contends that the determination whether to
    synchronize the text cursor to the audio cursor, or vice-
    versa, depends on the editing information entered by the
    user. Nuance asserts, however, that in Schulz, “the
    Case: 20-1549    Document: 63      Page: 16    Filed: 03/10/2021
    16             NUANCE COMMUNICATIONS, INC.     v. MMODAL LLC
    positions of cursor 60 and location 61 (the edit insertion
    point) are always determined solely by the location of the
    audio cursor 60 because the location 61 is merely the
    position of audio cursor 60 at an earlier point in time.”
    Appellant’s Br. 56–57. We are unpersuaded by Nuance’s
    argument. As the Board determined, for claim 10, Schulz’s
    insertion point 61 (the text cursor) realigns (i.e.,
    synchronizes) with the audio cursor after the user presses
    an edit function key. See J.A. 256–57. Moreover, this
    process remains the same regardless whether there is a
    reaction time variable (as in the second obviousness
    ground) or there is no reaction time variable (as in the first
    obviousness ground).
    With respect to claim 13, Nuance asserts that the claim
    language requires decoupling the text and audio cursors,
    whereas the edit insertion point 61 in Schulz is “always
    tied to the cursor 60.” Appellant’s Br. 55. We disagree.
    Here, the Board found that Schulz’s insertion point 61 is
    coupled to the audio cursor 60 only in synchronous
    playback mode. J.A. 187–88. The Board then reasonably
    determined, with support from the specification, that when
    playback mode is stopped and changed to text editor mode,
    the audio and text cursors can be uncoupled such that the
    text cursor can be used as a normal text editor. See, e.g.,
    J.A. 188 (quoting J.A. 1447 at col. 13 ll. 22–27). Moreover,
    this process remains the same regardless whether there is
    a reaction time variable (as in the Board’s second
    obviousness ground) or there is no reaction time variable
    (as in the Board’s first obviousness ground). 3
    Nuance also asserts that this court’s decision in
    Arthrex v. Smith & Nephew, Inc.,

    3  To the extent that Nuance’s arguments here are
    duplicative of its arguments regarding the independent
    claims, our analysis regarding the independent claims ap-
    plies here too.

    issue here, did not cure the Appointments clause defect.
    However, we have reiterated that final written decisions
    issued after Arthrex were decided by constitutionally
    appointed Administrative Patent Judges. See Caterpillar

    CONCLUSION
    We have considered Nuance’s remaining arguments
    and find them unpersuasive. For the foregoing reasons,
    the decisions of the Board are affirmed.
