“For purposes of this Decision, we adopt the definition of the level of ordinary skill in the art proposed by Petitioner. As to the inclusion of physics in Petitioner’s definition, Patent Owner acknowledges that an undergraduate mechanical engineering degree holder would have the requisite knowledge here but does not adequately explain why an undergraduate physics degree holder would not. In addition, Patent Owner requires “a four-year degree in mechanical engineering or a closely related field,” but fails to identify what fields are “closely related.” See Prelim. Resp. 10 (emphasis added). Based on the Winkel Declaration, we are persuaded at this stage that a hypothetical undergraduate physics degree holder would have had adequate knowledge for one of ordinary skill in the art of the invention here. See Winkel Decl. ¶ 106. As to the requisite years of experience proposed in the definitions— three for Petitioner versus “at least one” for Patent Owner—we note that Patent Owner’s definition is broader than, but includes, Petitioner’s definition. Moreover, for both the inclusion of physics and the years of experience issues, Patent Owner acknowledges that the arguments in the Preliminary Response “are not impacted based on which definition is applied.” Prelim.

Further, Patent Owner does not argue at this stage that Petitioner’s proposal for the level of ordinary skill leads to an improper understanding of how a skilled artisan would have understood either the challenged patent or the prior art.” slip op. at 11

“B. Claim Construction In inter partes reviews, the Board interprets claim language using the same claim construction standard that would be used in a civil action under 35 U.S.C. § 282(b), as described in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b). Under that standard, we generally give claim terms their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14. Although extrinsic evidence, when available, may also be useful when construing claim terms under this standard, extrinsic evidence should be considered in the context of the intrinsic evidence. See id. at 1317–19. Petitioner does not propose express constructions for any claim terms. Pet. 12. Patent Owner also does not propose any express constructions. See Prelim. Resp. 12. On the current record, we need not construe explicitly any claim terms. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

Although Patent Owner points to the District Court’s Memorandum in Support of Claim Construction Order (id. at 32 (citing Ex. 2002, 26)) to support its contention that the District Court construed the term “enabled,” as we determined in the Decision to Institute, this portion of the District Court’s Memorandum merely discusses that “hybrid device” is not indefinite, and discusses exemplary operations of the “hybrid device” from which a POSITA “could reasonably ascertain the scope of the claim.” See Dec.

Thus, as we previously explained, by determining that “hybrid device” is not indefinite, the District Court did not construe the term “enabled.” Id.; see also Ex. 2002, 26.

The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of non-obviousness.9 See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966).” slip op. at 25

Reply 3; see also IPR2024- 00405, Ex. 1001, 22:43–60; IPR2024-00407, Ex. 1001, 22:36–49; IPR2024- 00573, Ex. 1001, 21:51–65. As the Federal Circuit stated, when a disputed claim limitation does not employ “means for” language, the presumption is that each of the terms conveys sufficiently definite structure or act and, thus, is not subject to § 112 ¶ 6. See Dyfan, 28 F.4th at 1367. Based on the record before us, this presumption that each of the terms is not subject to § 112 ¶ 6 is not overcome.” slip op. at 18

“construction for “enabling one or more of an application, a function, and a service,” as recited in claim 1. Although Patent Owner points to the District Court’s Memorandum in Support of Claim Construction Order (id. at 32 (citing Ex. 2002, 26)) to support its contention that the District Court construed the term “enabling,” as we determined in the Decision to Institute, this portion of the District Court’s Memorandum merely discusses that “hybrid device” is not indefinite, and discusses exemplary operations of the “hybrid device” from which a POSITA “could reasonably ascertain the scope of the claim.” See Dec. Inst. 9. As we explained, a determination of whether a term is indefinite is not the same thing as construing a claim term. Id. Thus, as we previously explained, by determining that “hybrid device” is not indefinite, the District Court did not construe the term “enabling.” Id.; see also Ex. 2002, 26. Accordingly, nothing in the Memorandum provides a construction of “enabling” as Patent Owner contends. Id. Thus, we find unavailing Patent Owner’s contention that “nowhere does Dua teach or describe . . . providing an access key in exchange for information held locally in the PDK’s service blocks.” PO Resp. 33. That is, we decline to adopt Patent Owner’s proposed construction that an application, function or service is “enabled” by a PDK “when it receives information from a PDK in exchange for an access key.” Id. at 32.” slip op. at 39

“We find Patent Owner’s arguments unavailing, as they rely on Patent Owner’s arguments that “the specification defines ‘local, secured information’ as information stored within a service block of a PDK and unlocked with a corresponding access key provided to the PDK” (PO Resp. 30), with which, as discussed above, we do not agree. Dua discloses an “RFID Tag-Reader Module” which includes “Tag Memory 322” that may be tamper resistant. See Ex. 1004 ¶¶ 105, 109. Thus, we find persuasive Petitioner’s reliance on Dua’s Tag Memory 322, which locally stores information in a tamper-resistant manner, for teaching an integrated, secure memory for storing information locally, wherein the information is secured. Id. Based on the complete record presented, we determine that Petitioner has persuasively shown that the proposed combination of Dua and Giobbi ’157 teaches “an integrated, secure memory storing local, secured information,” as recited in claim 1.” slip op. at 34

“would have found it obvious to combine the teachings of Dua and Giobbi ’157 (Pet. 31), citing Dr. Wolfe’s supporting testimony (Ex. 1003). In particular, Petitioner posits that POSITA would have been motivated and found it obvious to “securely store the financial information in its tamper-resistant tag ‘to prevent hackers from retrieving confidential information’” (Pet. 31 (citing Ex. 1003 ¶¶ 105, 109)), as disclosed by Giobbi ’157. As Petitioner points out, Giobbi ’157 teaches “credit/debit card information” that is stored in a “profile memory field 232” in the “physical access secured and tamperproof” memory (id.; see Ex. 1006 ¶¶ 36, 42, 63), and we find persuasive Petitioner’s contention that a POSITA would have reasonably expected to succeed in “storing the ‘credit card profile or other payment information’ in Dua’s tamper resistant tag memory,” wherein such combination “would have been no more than combining prior art elements according to known methods to yield predictable results.” Id. (citing Ex. 1003 ¶ 158). Patent Owner does not address Petitioner’s positions on combining the teachings of Dua and Giobbi ’157 and thus Petitioner’s positions stand unopposed as a part of this trial. We have reviewed Petitioner’s explanations and supporting evidence regarding Petitioner’s proffered reasoning to combine the references, and we agree with and adopt them as our own.

Instead, the language in the prosecution history is consistent with the ordinary and customary meaning. That is, the applicant focuses on the location of the object relative to the area of game play, i.e., the foreground. For example, the applicant distinguishes Chu’s object as not being “background objects” because they “are featured in the forefront of [the] game play as primary objects to be manipulated or used during game play (see Chu at ¶¶ [0063]–[0065]).” Ex. 1002, 85 (emphasis added).12 The applicant continued by arguing that Chu’s objects “exist in the background, outside of the primary focus of game play and as unexpectedly interactive components, and are not themselves needed or required in order to play the game.” Id.

“We find that, after Burger’s network server 114 authenticates a user’s pocket vault ID, the user is granted access to pocket vault 102 and can select a transaction from a displayed menu, including use of a credit card. subsequent access to that credit card information, either by displaying it or through token 102a, is because network server 114 sent a communication to pocket vault 102 indicating that it successfully authenticated the pocket vault. Ex. 1003 ¶ 115. This is the obvious inference a skilled artisan would have drawn from Burger’s description of authenticating the pocket vault and subsequently allowing credit card information to be used. Thus, we find that, in this example, the operator of network server 114 is a third party that operates a trusted authority, the principle parties to the transaction are the user of pocket vault 102 and the retailer, and a message from network server 114 to pocket vault 102 allowing the credit card to be used (displayed or encoded in the token) is an access message allowing the user access to the application (file with credit card information).
