`U.S. Patent No. 10,073,960
`
`INTRODUCTION
`Petitioner Google LLC submits this reply to address Patent Owner Proxense,
`
`LLC’s contention that the term “enabling one or more of an application, a function,
`
`and a service” should be expressly construed to require information be received from
`
`a PDK in exchange for an access key. Paper 8, at 3. But before Proxense filed its
`
`preliminary response, the Board already rejected Proxense’s nearly identical
`
`arguments, found no explicit construction of this term necessary, and instituted
`
`review in Microsoft Corporation v. Proxense, LLC, IPR2024-00405, Paper 8 (PTAB
`
`July 22, 2024). In that case, Proxense advanced the “same constructions,” Paper 8,
`
`at 3, requesting the term “enabling one or more of an application, a function, and a
`
`service” be construed to include an exchange for an access key. Despite invoking a
`
`means-plus-function analysis for the first time, Proxense’s Patent Owner
`
`Preliminary Response in this case, has not added any compelling new arguments or
`
`evidence. Paper 5, at 2-19. The Board should reject Proxense’s proposed
`
`construction, and institute review.
`
`II. ARGUMENT
`A. The Enabling Term Is Not Subject to Means-Plus-Function
`Interpretation
`Proxense contends that the “enabling” term “may further be defined by way
`
`of a means-plus-function analysis” because each of the terms “local secured
`
`1
`
`
`
`
`information, wireless communication interface, and enablement signal” performs
`
`IPR2024-00784 Petitioner’s Preliminary Reply
`U.S. Patent No. 10,073,960
`
`the function of “enabling” and “are not sufficiently definite structure.” Paper 5, at 8-
`
`9.1 Not once had Proxense, in any of the related district court litigations, argued that
`
`any terms required § 112, ¶ 6 analysis. See, e.g., Exs. 1024-1027. Indeed, they are
`
`not subject to a means-plus-function analysis.
`
`At the outset, none of the claims of the ’960 patent recite the disputed
`
`limitations in “means-plus-function” or “step-plus-function” format. See, e.g., ’960
`
`patent, claims 1-3, 6-8, 10 and 14-16. Nor does Proxense argue that “local secured
`
`information, wireless communication interface, and enablement signal” are nonce
`
`words used as a substitute for “means” or “step.” Because the disputed claim
`
`limitations do not employ “means for” or “step for,” the presumption is that the terms
`
`local secured information, wireless communication interface, and enablement signal
`
`each convey sufficiently definite structure or act and, thus, are not subject to § 112,
`
`¶ 6. Dyfan, LLC v. Target Corp., 28 F.4th 1360, 1367 (Fed. Cir. 2022).
`
`
`1 The Board already considered and rejected Proxense’s arguments that (1) the
`
`court in Proxense v. Samsung previously construed the term “enabled,” Paper 5, at
`
`4, 8; and (2) the ’960 patent implicitly defines “enabling” through several
`
`examples in the specification, id., at 12-19. IPR2024-00405, Paper 8, at 11-17.
`
`2
`
`
`
`IPR2024-00784 Petitioner’s Preliminary Reply
`U.S. Patent No. 10,073,960
`
`The cases Proxense cited—HTC Corp. v. IPCom GmbH & Co., KG, 667 F.3d
`
`
`
`1270 (Fed. Cir. 2012); and Rain Computing v. Samsung Electronics America, 989
`
`F.3d 1002 (Fed. Cir. 2021)—are all inapposite. In all those cases, the disputed claim
`
`terms are expressly means-plus-function limitations. See, e.g., HTC Corp., 667 F.3d
`
`at 1280 (The parties agreed that the term “arrangement for reactivating” was a
`
`means-plus-function limitation.”); Rain Computing, 989 F.3d at 1006 (finding the
`
`word “module” was a black box recitation of structure “as if the term ‘means’ had
`
`been used”).
`
`In contrast, the terms “local secured information,” “wireless communication
`
`interface,” and “enablement signal” provide sufficiently definite structure or an act,
`
`because they are “not used as ‘generic terms or black box recitations of structure or
`
`abstractions.’” Dyfan, 28 F.4th at 1368 (“Unlike in the mechanical arts, the specific
`
`structure of software code and applications is partly defined by its function.”); see
`
`also Ex. 1009, 3-4. Thus, the recitation of “enabling one or more of an application,
`
`a function, and a service” does not change this. Contrary to Proxense’s argument,
`
`Paper 5, at 17-19, when a “structure-connoting term … is coupled with a description
`
`of the [term’s] operation” § 112 ¶ 6 does not apply. Linear Tech. Corp. v. Impala
`
`Linear Corp., 379 F.3d 1311, 1320 (Fed. Cir. 2004); Dyfan, 28 F.4th at 1368.
`
`Additionally, Proxense’s argument that “enablement signal” is “nothing more than
`
`the signal sent via the wireless communication interface,” Paper 5, at 9, is contrary
`
`3
`
`
`
`
`to the ’960 patent specification but more importantly irrelevant, because claims 14
`
`IPR2024-00784 Petitioner’s Preliminary Reply
`U.S. Patent No. 10,073,960
`
`and 16 are method claims, and each of “generating an enablement signal” and
`
`“sending the enablement signal” is an act that precludes treatment under § 112 ¶ 6.
`
`Because the terms themselves connote sufficient structure, the presumption that
`
`§ 112, ¶ 6 does not apply is “determinative.” Dyfan, 28 F.4th at 1366.
`
`B. Even if Construed as Means-Plus-Function, the Algorithm is
`Broader Than Proxense Argues
`But, even if these terms are means-plus-function or steps-plus-function terms,
`
`Proxense is wrong that “the only algorithm disclosed in the specification” is that of
`
`“a service block … providing the corresponding access key.” Paper 5, at 10. Notably,
`
`the ’960 patent discloses a hybrid device providing “additional functionality” where
`
`an access key is not required, including using “credentials ( credit card, account
`
`information, etc.) … to enable a service,” using “cellular service account
`
`information … to enable specific cellular services,” using “personal ID” to identify
`
`an account, etc. ’960 patent, 16:42-46, 17:5-50; see also Ex. 1003, ¶¶91-95. The
`
`’960 patent further explains that “[a]ny variety of different types of [external]
`
`devices may be coupled to signal line 1406 [to an RDC] to receive the authorization
`
`or enabling signal.” ’960 patent, 17:59-61; Fig. 14. Thus, the “algorithm” is not
`
`limited to that of an “access key.”

`
`C. The Board Need Not Construe the “Enabling” Term to Resolve the
`Controversy
`The Board also need not construe the term here because it is not necessary to
`
`resolve the controversy. Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795,
`
`803 (Fed. Cir. 1999). Regardless of the construction, Dua and Buer render the claims
`
`obvious. As the Petition explains, Dua discloses receiving RFID transmission data
`
`from the external tag (PDK) in exchange for information such as “communication
`
`settings, media processing capabilities, and other parameters” (access key under
`
`Proxense’s construction, as evidenced by its infringement contentions) for
`
`establishing a wireless connection with the external device. See, e.g., Pet. 23-27, 30-
`
`31; Ex. 1003, at ¶¶120-130, 139-143. Buer similarly discloses receiving necessary
`
`authentication information from the tag (PDK), including “cryptographic keys”
`
`(access keys) to extract credentials to enable a wide variety of applications,
`
`functions, or services on the hybrid device. See, e.g., Pet. 49-55, 58-59; Ex. 1003, at
`
`¶¶184-193, 204-210. Thus, the Board should institute review and cancel all claims.
