Before PROST, WALLACH, and CHEN, Circuit Judges. Opinion for the court filed by Circuit Judge CHEN. Dissenting opinion filed by Circuit Judge WALLACH. CHEN, Circuit Judge. CPC Patent Technologies Pty Ltd. (CPC) appeals from two final written decisions by the Patent Trial and Appeal Board (Board), both of which held the challenged claims in U.S. Patent No. 8,620,039 (’039 patent) unpatentable un- der 35 U.S.C. § 103. ASSA ABLOY AB v. CPC Pat. Techs. PTY, Ltd., No. IPR2022-01093, 2024 WL 378066, at *1 (P.T.A.B. Jan. 31, 2024) (Final Decision I); ASSA ABLOY AB v. CPC Pat. Techs. PTY, Ltd., No. IPR2022-01094, 2024 WL 378074, at *1 (P.T.A.B. Jan. 31, 2024) (Final Decision II). For the following reasons, we reverse and remand both decisions. BACKGROUND I CPC owns the ’039 patent, which relates to credit card security, and in particular, biometric verification of the user. ’039 patent col. 1 ll. 13–15, col. 2 ll. 10–22, col. 2, ll. 51–61. Biometric verification ensures that the identity of the customer using a credit card matches the identity of the registered card owner, thereby assuring that only the au- thorized owner of the card can initiate transactions. This requires storing not only the user’s credit card number, but also his or her biometric signature, such as a fingerprint. Id. col 2. ll. 23–26. During a transaction, a biometric reader collects the bi- ometric data of the customer. The biometric reader then sends that biometric information, along with the credit Case: 24-1492 Document: 50 Page: 3 Filed: 11/10/2025

CPC PATENT TECHNOLOGIES PTY LTD. v. ASSA ABLOY AB 3

card information retrieved from the card reader, to a back- end system. The back-end system in turn checks for a match, and if a match exists, the transaction proceeds. The ’039 patent recognizes that biometric verification mechanisms existed within the prior art. See, e.g., id. FIG. 2 (depicting prior art biometric verification mechanisms). The ’039 patent, however, purports to introduce a particu- lar way of storing the biometric data during enrollment of any given user: “[t]he biometric signature is stored at a memory address defined by the (‘unique’) card information on the user’s card as read by the card reader of the verifi- cation station.” Id. col. 2 ll. 64–67. Claim 1, representative 1 for both appeals, recites: A method of enrolling in a biometric card pointer system, the method comprising the steps of: receiving card information; receiving the biometric signature; defining, dependent upon the received card information, a memory location in a local memory external to the card; determining if the defined memory location is unoccupied; and

1 Both parties focused on a particular limitation in this claim and treated it as representative for the appeal as to all challenged claims. We do so too. But as we note below, we summarily affirm the cancellation of claim 1 in a different IPR (which relied on different prior art). See infra Discussion Section I. Therefore, our discussion about errors the Board made in this appeal only extends to claims 3–18, which were not at issue in the other appeal. Case: 24-1492 Document: 50 Page: 4 Filed: 11/10/2025

storing, if the memory location is unoccu- pied, the biometric signature at the defined memory location. Id. at claim 1. CPC, on appeal, focuses on the third limitation, “defin- ing, dependent upon the received card information, a memory location in a local memory external to the card.” Id.; see generally Appellant’s Br. II Only one prior art reference, Hsu, 2 is relevant to this appeal. Hsu, much like the ’039 patent, describes a bio- metric verification mechanism. See Hsu ¶ 6. During en- rollment, Hsu requires each user to present (1) a fingerprint and (2) his/her personal identification, such as an employee number, account number, card number, etc.— the system assigns an identifying number if the user does not yet have one. Id. ¶ 26. Hsu then teaches storing the personal identification number “in association with” the user’s fingerprint image data. See id. (“The account num- ber is stored in the database . . . in association with the user’s fingerprint image data.”). III ASSA Abloy AB (ASSA) petitioned for two inter partes reviews of the ’039 patent. In its first petition, ASSA chal- lenged claims 1–2, 13–14, and 19–20 as unpatentable over two prior art combinations, both of which relied on Hsu. See Final Decision I, 2024 WL 378066, at *3. And its sec- ond petition challenged claims 3–12 and 15–18 as un- patentable over several prior art combinations, all of which again relied on Hsu. See Final Decision II, 2024 WL

378074, at *4. The Board instituted review on both peti- tions. Of relevance in the first proceeding, the Board issued a claim construction for “defining.” See Final Decision I, 2024 WL 378066, at *6–7. It agreed with CPC that “defin- ing” “mean[s] ‘setting’ or ‘establishing,’” explaining that “[o]nce the card information and fingerprint are received during enrollment, the card information provides data that establishes where, i.e., at what memory location or address, the system will store the fingerprint data.” Id. at *7. The Board adopted an identical construction in the second pro- ceeding. See Final Decision II, 2024 WL 378074, at *6–8. After setting forth its construction, the Board turned to Hsu. It reiterated how Hsu’s “fingerprint data [is] associ- ated with corresponding user numbers.” Final Decision I, 2024 WL 378066, at *14 (quoting Hsu ¶ 26). That, in the Board’s view, sufficed for having the card data “define” the memory location of biometric data because “the ‘associa- tion’ is the where,” i.e., “where the fingerprint data is stored.” Id. at *15. The Board ultimately held that ASSA’s first ground rendered the challenged claims unpatentable, and didn’t reach ASSA’s second ground. The second pro- ceeding followed a similar analysis. See Final Decision II, 2024 WL 378074, at *13–16. CPC appeals both decisions, contending the Board mis- applied its construction of “defining” to Hsu. 3 We consoli- dated both appeals. We have jurisdiction under 28 U.S.C. § 1295(a)(4).

3 Both CPC and ASSA treat the two appeals identi- cally, focusing their arguments on the first proceeding. See generally Appellant’s Br.; Appellees’ Br. We therefore cite only to the first proceeding. See Final Decision I, 2024 WL 378066. Case: 24-1492 Document: 50 Page: 6 Filed: 11/10/2025
