`U.S. Pat. No. 8,923,941
`
`
`
`Pursuant to the Board’s September 14 Order, Patent Owner Valencell, Inc.
`
`submits this Response Brief to Petitioner Fitbit, Inc.’s Opening Brief on Remand.
`
`I.
`
`Apple’s Petition Fails to Demonstrate that Claims 3-5 Are Obvious.
`The Federal Circuit remanded this proceeding because the Board “did not
`
`review the patentability of claim 3, as construed, on the asserted grounds of
`
`obviousness.” Fitbit, Inc. v. Valencell, Inc., 964 F.3d 1112, 1117-18 (Fed. Cir. 2020)
`
`(emphasis added). Similarly, with respect to claims 4 and 5, the Federal Circuit
`
`remanded for the Board to “determine patentability of corrected claims 4 and 5 on
`
`the asserted grounds of obviousness.” Id. at 1120 (emphasis added). Thus, the Board
`
`is tasked with evaluating whether Fitbit has met its burden of demonstrating that
`
`claims 3-5, properly construed, are obvious based on the arguments made and the
`
`evidence cited in Apple’s Petition. It has not.
`
`In the Petition, Apple asserted that Craw discloses an application-specific
`
`interface of claim 3: “Craw teaches that a data dictionary used with data classes acts
`
`as an API for managing, extracting, and displaying information from information
`
`streams.” Paper 2 at 27 (citing Ex. 1056 ¶ 256) (emphasis added). But neither Apple
`
`nor Fitbit demonstrate that Craw discloses “an interface which enables a particular
`
`application to utilize data obtained from hardware, such as the at least one motion
`
`sensor and the at least one PPG [photoplethysmography] sensor.” See Fitbit, 964
`
`F.3d at 1116-17 (emphasis added). As Apple conceded in the Petition, an API has
`
`1
`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`“broad applicability to different applications—and [is] not ‘application specific’ as
`
`such.” Paper 2 at 14 (emphasis added); Ex. 1003 ¶ 62 (same). Indeed, Craw’s data
`
`dictionary and data classes are not directed to any “particular application.” Rather,
`
`as Apple’s expert explained, they provide “a generic mechanism” to access “all
`
`types of definitions” and “a generic interface” used by “any software project.”
`
`Ex. 1003 ¶¶ 75-76 (citing Ex. 1056 ¶¶ 253, 255) (emphasis added). Indeed, Craw’s
`
`entire aim is interoperability. Ex. 1056 ¶¶ 8-10. Because Craw’s data dictionary and
`
`data classes are generically applicable to different applications, they do not disclose
`
`an application-specific interface. See Paper 2 at 14; Ex. 1003 ¶ 62.
`
`Alternatively, Apple asserted in the Petition that Lee disclosed the
`
`application-specific interface of claim 3: “Lee teaches multiple APIs and, in
`
`particular, a wireless communications API (i.e., Bluetooth) to provide an interface
`
`between a physiological parameter extraction device (i.e., a hemadynamometer) and
`
`a mobile device.” Paper 2 at 57-58 (emphasis added). But, again, Lee’s API is
`
`designed to work with various applications. As Apple’s expert explains, “[a]fter a
`
`connection has been set up …, the mobile phone application programs can easily
`
`use a serial port transmission protocol to receive physiological parameter
`
`measurement data.” Id. ¶ 161 (citing Ex. 1059 at 511) (emphasis added). Because
`
`the Bluetooth API has broad applicability to different applications, it is not an
`
`application-specific interface. See Paper 2 at 14; Ex. 1003 ¶ 62.
`
`2
`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`With respect to claims 4 and 5, Apple’s Petition evaluated obviousness based
`
`only on an incorrect dependency from claim 1. See Paper 2 at 29 (“As discussed
`
`above, the combination of Luo and Craw suggests all the limitations of claim 1 as
`
`arranged in the claim.”). Apple’s expert did the same. Ex. 1003 ¶ 92 (“As discussed
`
`above, the combination of Luo and Craw suggests the method of claim 1.”). Because
`
`Apple’s Petition did not evaluate obviousness based on the correct dependency of
`
`claims 4 and 5 from claim 3, Apple’s Petition failed to show that the combination of
`
`Luo, Craw, and Wolf renders obvious all limitations of claims 4 and 5 (i.e., the
`
`limitations of claim 3). See Alcon Research, Ltd. v. Apotex, Inc., 687 F.3d 1362,
`
`1367 (Fed. Cir. 2012) (“[A dependent claim] must ‘incorporate … all the limitations
`
`of the claim to which it refers.’”).
`
`Regardless, because the asserted grounds in Apple’s Petition failed to
`
`demonstrate the obviousness of claim 3, the asserted grounds of obviousness in
`
`Apple’s Petition against claims 4 and 5 necessarily fail as well. See Hartness Int’l,
`
`Inc. v. Simplimatic Eng’g Co., 819 F.2d 1100, 1108 (Fed. Cir. 1987) (“[T]he district
`
`court was correct in holding that independent claim 1 was nonobvious. A fortiori,
`
`dependent claim 3 was nonobvious (and novel) because it contained all the
`
`limitations of claim 1 plus a further limitation.”).
`
`Apple’s Petition also failed to explain why a skilled artisan would have
`
`combined Craw and Wolf with Luo and Lee with Mault and Al-Ali in the way the
`
`3
`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`inventions of claims 3-5 do (e.g., so that an application-specific interface can perform
`
`further data processing). See Paper 2 at 27, 31, 58-59. Although Apple’s expert
`
`asserted that it would have been obvious to combine these references to arrive at
`
`claims 3-5, his testimony is nothing more than unsupported ipse dixit. See Ex. 1003
`
`¶¶ 92-93, 104, 162-63. This is insufficient to support obviousness. See TQ Delta,
`
`LLC v. CISCO Sys., Inc., 942 F.3d 1352, 1362 (Fed. Cir. 2019).
`
`II. The Board Should Reject Fitbit’s Arguments Because They Are Not
`Limited to the Challenges in Petitioner Apple Inc.’s Petition.
`A remand “does not change [the Board’s] focus on the Petition as Petitioner’s
`
`case-in-chief ….” adidas AG v. Nike, Inc., IPR2016-00922, 2018 WL 4056113, at *3
`
`(P.T.A.B. Aug. 24, 2018) (emphasis added). The “petitioner’s contentions [in the
`
`petition] ... define the scope of the litigation all the way from institution through to
`
`conclusion.” SAS Inst., Inc. v. Iancu, 138 S. Ct. 1348, 1355 (2018). The Petition must
`
`identify “[h]ow the construed claim is unpatentable” and “specify where each
`
`element of the claim is found in the prior art patents or printed publications relied
`
`upon.” 37 C.F.R. § 42.104(b)(4). A petitioner cannot use later briefing as “an
`
`opportunity to start anew, to fill in gaps or to remedy omissions in a petition.” Cisco
`
`Sys., Inc. v. Oyster Optics, LLC, IPR2017-01719, 2019 WL 328734, at *10 (P.T.A.B.
`
`Jan. 24, 2019). Yet that is exactly what Fitbit attempts to do. Faced with the reality
`
`that Apple’s Petition does not demonstrate that claims 3-5 are obvious, Fitbit
`
`purports to fill in gaps and remedy omissions in the Petition by relying on new
`
`4
`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`disclosures from Craw and making new arguments. As demonstrated herein, each of
`
`these arguments should be rejected by the Board.
`
`A. Fitbit Improperly Attempts to Expand the Petition’s Challenge to
`Claim 3 by Relying on New Disclosures From Craw.
`In the Petition, Apple argued only that “Craw teaches that a data dictionary
`
`used with data classes acts as an API for managing, extracting, and displaying
`
`information from information streams.” Paper 2 at 27 (citing Ex. 1056 ¶ 0256)
`
`(emphasis added); see also Ex. 1003 ¶ 92 (citing Ex. 1056 ¶ 256). Other than the
`
`data dictionary from paragraph 256 of Craw, Apple’s Petition does not identify any
`
`other disclosure in Craw that allegedly teaches or discloses the claimed application-
`
`specific interface. Notably, Apple never argued in the Petition that Craw discloses
`
`the claimed application-specific interface under the Board’s construction of the term.
`
`While Apple later attempted to make that argument in its subsequent Request for
`
`Rehearing of Institution Decision and post-SAS brief, the Board correctly concluded
`
`that it “cannot have overlooked or misapprehended an argument that the Petitioner
`
`did not make” in the Petition. Paper 15 at 6-7 (emphasis added). For the same reason,
`
`Fitbit cannot make that new argument now.
`
`Nevertheless, Fitbit attempts to do just that. Relying on previously uncited
`
`portions of Craw, it alleges – with only bare attorney argument – that “Craw’s
`
`‘interfaces’ each qualify as an ‘application-specific interface (API)’ under the
`
`Board’s narrowing construction.” Paper 60 at 5-6 (emphasis added) (citing Ex. 1056
`
`5
`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`¶¶ 48, 149, 202-203). Fitbit further relies on previously uncited paragraph 208 and
`
`Figure 9A of Craw to argue that “Craw teaches that a health-monitoring application,
`
`such as the blood pressure application in Figure 9A, uses the disclosed interfaces in
`
`order to display extracted health data.” Id. at 6. Fitbit also relies on a new
`
`“interpreter” in paragraph 48 of Craw. Id. at 7.
`
`But Apple’s Petition did not rely on any of these disclosures to support its
`
`argument that Craw discloses the application-specific interface of claim 3. It relied
`
`solely on the combination of the data dictionary and data classes from paragraph 256
`
`of Craw. See Paper 2 at 27; see also Ex. 1003 ¶ 92. And Apple and its expert never
`
`argued in the Petition that Craw’s “interfaces” “perform the same function” as the
`
`claimed application-specific interface under the Board’s construction thereof or that
`
`Craw’s “‘interfaces’ … can be specifically tailored to each ‘particular application,’”
`
`as Fitbit does in its Opening Brief. See Paper 60 at 6-7.
`
`In addition, Fitbit attempts to rely on the Board’s reasoning from a different
`
`proceeding (IPR2017-00321) regarding a different claim. See Paper 60 at 7-8. But
`
`the challenges asserted in IPR2017-00321 are significantly different from the
`
`challenges asserted in this proceeding. In the Petition, Apple relied on the
`
`combination of Luo and Craw. In IPR2017-00321, Apple relied on different prior
`
`art combinations. See IPR2017-00321, Paper 44 at 57. Thus, Fitbit cannot rely on
`
`the final written decision in IPR2017-00321. See Paper 57 at 6. Further, arguments
`
`6
`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`from a prior proceeding “cannot be incorporated by reference in its Petition in this
`
`proceeding.” Google, Inc. v. SimpleAir, Inc., CBM2015-00019, 2014 WL 8879049,
`
`at *6 (P.T.A.B. May 19, 2014). Tellingly, although the Board’s decision in IPR2017-
`
`00321 was mailed well after Apple filed the Petition in this case, Apple never sought
`
`authorization to supplement its briefing to address any potential implications of that
`
`decision to this proceeding, see Paper 43 at 17, and neither has Fitbit.
`
`Fitbit’s attempt to rely on previously uncited portions of Craw is equivalent
`
`to the submission of new evidence, which the Board specifically precluded in its
`
`September 14 Order. See Paper 57 at 7-8. As the Board noted in its Order, Apple
`
`had “expressly argued that, even under our construction of the term ‘application-
`
`specific interface (API),’ now affirmed by the Federal Circuit, the Petition is
`
`sufficient to show that claim[s] 3–5 are rendered obvious over the combined
`
`teachings of the applied references.” Id. at 8 (emphasis added). Thus, Fitbit is bound
`
`by the arguments and evidence cited by Apple in the Petition and should not be
`
`permitted to rely on different grounds or portions of Craw never cited in Apple’s
`
`Petition for the disclosure of the claimed application-specific interface.
`
`B. Fitbit Improperly Attempts to Expand the Challenge to Claims 4-
`5 by Making New Arguments Based on the Correct Dependency.
`Claim 4 correctly depends from claim 3, not claim 1. See Fitbit, 964 F.3d
`
`at 1120. Yet, Apple argued in the Petition that the combination of Luo, Craw, and
`
`Wolf discloses the limitations of claims 4 and 5 based on the incorrect dependency.
`
`7
`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`Paper 2 at 29. As a result, Apple did not assert in the Petition that the combination
`
`of these references disclosed an application-specific interface. Instead, Apple’s
`
`Petition ignored this key limitation, arguing only that Wolf discloses the additional
`
`limitations of claims 4 and 5. See id. Now, Fitbit attempts to rely on its new analysis
`
`of claim 3 to support its analysis of claims 4 and 5, but that is improper since it is
`
`outside the scope of the challenge in Apple’s Petition. See Paper 57 at 6.
`
`Accordingly, the Board should not permit Fitbit to “fill in gaps” and “remedy
`
`omissions in a petition” by making new arguments based on the correct dependency
`
`of claims 4 and 5. See Cisco, 2019 WL 328734, at *10.
`
`C. Fitbit Improperly Attempts to Expand the Challenge to Claim 3 by
`Making New Arguments Regarding Lee.
`In the Petition, Apple never argued that Lee disclosed the claimed application-
`
`specific interface under the Board’s construction of the term. See Paper 2 at 55-58.
`
`And Apple never argued, as Fitbit does now, that “Lee discloses [sic] ‘application-
`
`specific interface (API)’ because Lee’s ‘mobile phone application program’ is a
`
`‘particular application’ using the data.” Paper 60 at 10. Indeed, Apple did not make
`
`any similar characterizations of Lee’s mobile application programs in the Petition.
`
`See Paper 2 at 55-58. Accordingly, the Board should not permit Fitbit to expand the
`
`scope of the challenge in the Petition by making new arguments regarding Lee’s
`
`disclosures. See Cisco, 2019 WL 328734, at *10.

`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`III. Fitbit Fails to Demonstrate that Claim 3 Is Obvious Under the Board’s
`Construction of “Application-Specific Interface.”
`While the Federal Circuit wrote that “[t]he Board’s narrowing construction
`
`may have no significance, where, as here, the claimed ‘application-specific
`
`interface’ performs the same function as an application programming interface, i.e.,
`
`‘enabl[ing] a particular application to utilize data obtained from hardware,’” this
`
`observation is, at best, dicta, and cannot be construed as a finding of fact. See Atl.
`
`Thermoplastics Co. v. Faytex Corp., 5 F.3d 1477, 1479 (Fed. Cir. 1993) (“Fact-
`
`finding by the appellate court is simply not permitted.”). There is simply no evidence
`
`that a generic API performs the same function as an application-specific interface.
`
`Fitbit argues that Craw’s “interfaces” and Lee’s Bluetooth API can be used
`
`with a particular application. Paper 60 at 6-8, 10. But that does not mean that these
`
`APIs are application-specific interfaces. Indeed, the Board previously rejected
`
`Apple’s argument that claim 3 requires only that the application-specific interface
`
`“can utilize a particular application.” Paper 15 at 7 n.6. It must be “directed to a
`
`‘particular application,’ rather than broadly to different applications.” Paper 43 at 15
`
`(emphasis added). Fitbit’s claim that Craw discloses tailoring its API to a specific
`
`application takes Craw out of context. Paper 60 at 7. Fitbit quotes a statement from
`
`Craw’s background that “software may be configured to operate upon a particular
`
`subset of data.” Id. But that statement does not concern Craw’s “interfaces.” It
`
`concerns the prior art. And while the actions taken by Craw’s interpreter may
`
`9
`
`
`
`
`
`Case IPR2017-00319
`U.S. Pat. No. 8,923,941
`
`“depend on the goal of the application,” Craw’s “interfaces” are designed to be
`
`interoperable, so that they work with a variety of applications, which is the very
`
`opposite of application specific. See Ex. 1056 ¶¶ 10-11, 46-47, 51, 141-43.
`
`Moreover, an invention is not obvious merely because it performs the same
`
`function as the prior art. There must be no unexpected results. See TRW Automotive
`
`US LLC v. MAGNA Elecs., Inc., IPR2014-00251, 2014 WL 3945912, at *3
`
`(P.T.A.B. July 31, 2014). Yet, Fitbit provides no analysis, let alone evidence, that
`
`the substitution of the claimed application-specific interface for Craw’s or Lee’s API
`
`would not give unexpected results.
`
`Fitbit’s only reason for combining Craw and Wolf with Luo is their similar
`
`technology and problems addressed. Paper 60 at 5, 9. But this alone is not a sufficient
`
`rationale to support obviousness. See Securus Techs., Inc. v. Global Tel*Link Corp.,
`
`701 F. App’x 971, 977 & n.3 (Fed. Cir. 2017); Microsoft Corp. v. Enfish, LLC, 662
`
`F. App’x 981, 990 (Fed. Cir. 2016). Fitbit’s only basis to combine Lee, Mault, and
`
`Al-Ali is to allow communicating information to a device. Paper 60 at 10. But that
`
`conclusion is supported by nothing more than the hindsight bias of Fitbit’s expert
`
`and the expert’s ipse dixit. See Ex. 1003 ¶¶ 162-63.
`
`IV. CONCLUSION
`For the foregoing reasons, Valencell requests that the Board find, again, that
`
`Fitbit fails to meet its burden of demonstrating that claims 3-5 are unpatentable.
