“We begin with “the context in which a term is used in the asserted claim,” which can be “highly instructive.” Phillips, 415 F.3d at 1314. In this case, claim 1 recites that the claimed assay is “capable of unambiguously detecting the presence or absence of each of said at least M analytes, in any combination of presence or absence, in a single sample volume, . . . wherein the analytes are amplified in the single sample 15 In this regard, we note that Petitioner’s claim construction position is not predicated on the collection of droplets being reconstituted into its original, pre-partition form prior to amplification; rather, the droplets remain compartmentalized from each other in the PCR thermal cycling tube. Tr. 65:21–66:9 (Petitioner’s counsel explaining that the droplets do not combine in the PCR thermal cycling tube but, rather, are “suspended in an immiscible fluid and analyzed en masse”). indicates that the first instance of single sample volume, i.e., the single sample volume in which the presence or absence of each M analytes are to be detected, is the antecedent basis for the second instance of “single sample volume,” i.e., the single sample volume in which the analytes are amplified. Thus, as the parties appear to agree, the single sample volume in which amplification takes places must be the same single sample volume in which the presence or absence of analytes are to be detected. We are not persuaded that, when accorded its plain and ordinary meaning, a single sample volume divided into a collection of droplets would be considered the “same” single sample volume prior to its partition.” slip op. at 17

“With respect to the limitation, “wherein the analytes are amplified in the single sample volume,” Petitioner asserts that “Larson discloses PCR assays that amplify target polynucleotide in a single sample volume, specifically a portion of the reaction mixture that is subsequently partitioned into droplets.” Pet. 31 (emphasis added). There is no dispute that the amplification of the analytes in Larson occurs in the droplets. Larson ¶¶ 6–7 (explaining that “[d]igital PCR (dPCR) is an alternative quantitation method in which dilute sample are divided into many separate reactions” and that “[t]he template is amplified in the droplet for detection”) (emphasis added). Because the claims require that amplification of the analytes be in the same sample volume in which the at least M analytes, in any combination of presence or absence, is unambiguously detected, and because the pre-partition single sample volume is not the same single sample volume as the collection of droplets after partition under our claim construction set forth above, we find Petitioner has not shown, by a preponderance of evidence, that claims 1–10 and 13–19 are anticipated by Larson.17 Tr. 68:12–69:14 (Petitioner’s counsel” slip op. at 27

“We agree with Petitioner that claim 43 is obvious over the combination of Conlon, Miller, and Fong. The Federal Circuit stated, “[i]n this context, ‘normalization’ generally refers to de-duplicating and simplifying database entries (for instance, combining entries for ‘car’ and ‘automobile’).” Appeal Dec. 4 (cited at Pet. Response Br. 5). This is consistent with the disclosure in the ’433 patent. E.g., Ex. 1001, 16:55– 17:24 (discussing, for example, “recogniz[ing] that the differently named data elements in different structures are actually the same data element . . . is referred to as normalizing the names of the same data elements,” “recogniz[ing] that the same named data elements in different structures are actually different data elements . . . is referred to as normalizing the names of the different data elements,” and “normalizing multiple single data elements”). This is also consistent with how Fong describes “normalization.” Ex. 1029, 76 (The “Function” of “Normaliz[ing] the collection of entities” is to “[r]emove redundancies and detect errors”); see also Ex. 1057 ¶ 226. Patent Owner’s arguments that Fong’s normalization is “different” from the normalization described in the ’433 patent does not persuasively rebut Petitioner’s arguments. As Petitioner points out, Patent Owner does not provide a construction for “normalization,” despite claiming that the term is “defined” in the ’433 patent. Pet. Remand Resp. Br. 6; PO Remand Br. 13. Moreover, although Patent Owner purports to identify differences between the ’433 patent and Fong, the “normalization” applied is expressly recited in limitations [43.1.1], [43.1.2], and [43.2], and the subsequent actions taken on those normalized databases (i.e., comparing and recording) are recited in limitations [43.3]–[43.5]. That is, the “normalization” required by the claim is reflected in the claim language itself, and is broader than argued by Patent Owner. See In re Baxter Travenol Labs., 952 F.2d 388, 391 (Fed. Cir. 1991) (“It is not the function of this court to examine the claims in greater detail than argued by an appellant, looking for nonobvious distinctions over the prior art”). Patent Owner does not explain how these purported “differences” (e.g., that Fong may require the use of “database keys,” “identifiers,” “entities,” or determining ‘non-key attributes’ from key attributes) impacts the claim language, or Petitioner’s showing. See EWP Corp. v. Reliance Universal Inc., 755 F.2d 898, 907 (Fed. Cir. 1985) (A prior art reference “must be considered for everything it teaches by way of technology and is not limited to the particular invention it is describing and attempting to protect”). For the same reasons, as well as those set forth by Petitioner, we are also not persuaded by Patent Owner’s arguments that each DBMS requires a normalization process that is customized for it. Pet. Remand Resp. Br. 6–7. These arguments by Patent Owner also are not commensurate with the scope of the claim language, which does not recite a DBMS, and generally recites “normalizing” or “normalized” without regard to the DBMS. Id. Dr. Jansen provides an example of a database in unnormalized form that is converted into a normalized form, based on Fong’s four conditions, as applied to the claim language. See Reply 31–35; Ex. 1057 ¶¶ 226–261. Therefore, we are not persuaded by Patent Owner’s arguments that Petitioner has not explained how the example maps onto the limitations. PO Remand Resp. Br. 6–12. Patent Owner’s complaint that Dr. Jansen created the graphic in the example does not undermine Petitioner’s showing. E.g., Trial Practice Guide,14 I.G., (“Experts may testify about the teachings of the prior art and how they relate to the patentability of the challenged claims.”). We find Dr. Jansen’s testimony credible and persuasive in explaining why the combination of Conlon and Fong teaches the claim limitations. After considering the properly presented evidence and arguments of the complete record, we determine that Petitioner has shown, by a preponderance of the evidence, that the combination of Conlon, Miller, and Fong teaches the limitations in claim 43, that one of ordinary skill in the art would have been motivated to combine the teachings of Conlon, Miller, and Fong, and that claim 44 would have been obvious over Conlon, Miller, and Fong. 2. Analysis of Dependent Claims 44–46 Claims 44–46 depend, directly or indirectly, from claim 41. We, likewise, determine whether the combination renders obvious claims 44–46, taking into account the arguments made in Petitioner’s Reply Briefs and Dr. Jansen’s Supplemental Rebuttal Declarations. Petitioner contends that dependent claims 44–46, would have been obvious over Conlon, Miller, and Fong, and provides explanation as to how the prior art teaches each claim limitation.

“Patent Owner’s arguments do not undermine Petitioner’s showing. Patent Owner did not specifically challenge Petitioner’s contentions as to the sufficiency of Conlon’s disclosure for claim 1410 in the Patent Owner Response. In the Sur-replies, Patent Owner argues that the claim requires that at least some relationships are created “automatically,” and “these automatic embodiments . . . are represented in this group of claims.” Sur-reply 9. Along these lines, in the additional briefing Patent Owner argues that Conlon does not teach “automatic,” but merely teaches “semi-automatic.” PO Remand Br. 9–10. The crux of Patent Owner’s argument, however, is that the Federal Circuit did not properly construe the limitation, and ignored certain disclosures in the ’433 (and ’680) patent. Id. at 10–11; see Pet. Remand Resp. Br. 1–4; PO Remand Resp. Br. 4–5. The Federal Circuit held that “the dictionary routine claims can be satisfied by mere use of a lexical database, and do not also require the automatic creation of additional definitions.” Appeal Dec. 10. Moreover, the statements from Conlon that Patent Owner relies upon relate to creating a database, not using the database. See id. As discussed above, on remand we are directed to apply the Federal Circuit’s construction. Patent Owner does not explain 10 As discussed in the original Final Written Decisions, Patent Owner raised several arguments that generally applied to all the claims, challenging, for example, the level of ordinary skill in the art, whether Conlon, Miller, and Beckwith were analogous art, and several general arguments relating to Conlon and the motivation to combine Conlon with a DBMS. See Final Dec. 14–23, 25–27. We were not persuaded by Patent Owner’s arguments; the Federal Circuit affirmed, determining that our findings were supported by substantial evidence. Appeal Dec. 14–16. why Petitioner’s contentions are not persuasive in light of the Federal Circuit’s construction of this limitation. In addition, Patent Owner argues in the Sur-replies that “[c]laims 14– 19 are not disclosed by the proffered prior art” and cites to paragraphs 78–83 of the Ranka Rebuttal Declarations. Sur-reply 10. As discussed in the original Final Written Decisions, Patent Owner’s reliance on six paragraphs of Dr. Ranka’s Rebuttal Declarations is an improper incorporation by reference, as Patent Owner did not discuss that testimony or further elaborate on these arguments in the Sur-replies. 37 C.F.R. § 42.6(a)(3); Cisco Systems, Inc. v.

Therefore, we will not consider arguments that are not made in the Sur-replies, but are instead improperly incorporated by reference to the cited paragraphs in Dr. Ranka’s Rebuttal Declarations.

“With respect to Petitioner’s allegations that rest on AAPA, we determine Petitioner has failed to show that claims 2, 10, and 11 are unpatentable. Our rules require that a petition for inter partes review must base the asserted challenges on “prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b); 37 C.F.R. § 42.104(b)(2) and (4). And, a petitioner who relies on applicant admitted prior art as the basis, or part of the basis, of a ground, runs afoul of § 311. Qualcomm, 134 F.4th at 1365; see also USPTO Memorandum, Enforcement and Non-Waiver of 37 C.F.R. § 42.104(b)(4) and Permissible Uses of General Knowledge in Inter Partes Reviews (Jul. 21, 2025), available at www.uspto.gov/sites/default/ files/documents/aapa_memo_final__signed.pdf. We acknowledge but reject Petitioner’s position that its combinations discussing AAPA do not “rely” on AAPA but rather rely on U.S. Patent No. 5,793,185 (“the ’185 patent”), described in the ’203 patent as prior art. Pet. Reply 26. A petition for inter partes review must identify, “in writing and with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3); 37 C.F.R. § 42.104 (b)(4). Here, Petitioner’s contention that the Grounds 2 and 5 actually rely on the ’185 patent when discussing AAPA is inconsistent with the Petition. In particular, the Petition does not cite to or direct our attention to any specific details from the ’185 patent to support its challenges. See generally Pet. 54–57, 76–77. Accordingly, Petitioner has failed to show, by a preponderance of the evidence, that claims 2, 10, and 11 would have been unpatentable over the combination of Richardson, Zhao, and AAPA as well as over the combination of Yu, Paparrizos, and AAPA.

We also find that the portions of Pogge cited by Petitioner show that its “void 25 has an important function in relieving stresses caused by differences in the thermal coefficient of expansion (TCE) of the various materials in and around the feature” (Ex. 1005 ¶ 27) and that the portions of Edelstein cited by Petitioner show that, “[a]lthough it does not change the thermal expansion coefficient, the introduction of a void or voids reduces the effective modulus and Poisson ratio of the through-via, resulting in a compliant through-via that exerts much less stress and force on the surrounding structures” (Ex. 1006 ¶ 47). As discussed above, we find that Cooney’s void 25 is “entirely surrounded by” its conductive filler 24 that, in turn, is surrounded by liner 22 and substrate 10’. Ex. 1004, Fig. 6. We credit Petitioner’s relied-upon testimonial evidence that the presence of a void was known to reduce thermal stress in the surrounding substrate, because the citations to the record support it. Ex. 1002 ¶¶ 124–134; Ex. 1005 ¶¶ 1, 9, 25–28, Fig. 2D; that “a void can decrease thermal stress in the substrate”).

“And Patent Owner states that it “agree[s] with Petitioner’s construction” with respect to the MPF terms. PO Resp. 13. Although Patent Owner also contends that a “POSITA would understand the ‘means for transmitting’ to be a socket server transmitting through an event socket that implements the algorithms described in Figures 2, 3, 21A–21E and accompanying disclosures” (id.), Patent Owner’s proposed further construction is not disputed by Petitioner. See generally Pet. Reply. Furthermore, Petitioner’s proposed constructions of “socket” and “event socket” (Pet. 39) are not disputed by Patent Owner. PO Resp. 2, 13–14. In fact, by arguing that Spivey’s topic queues are neither “uniquely addressable” nor “communication endpoint[s],” Patent Owner appears to adopt Petitioner’s proposed construction of “socket” as a “uniquely addressable communication endpoint.” Id. at 2. As Patent Owner acknowledged during Oral Argument, “I don’t think there’s any dispute of what we mean by socket, a uniquely addressable communication endpoint.” Tr. 73:11–13.6 Thus, on this record, because there is no dispute between the parties regarding the terms “means for transmitting,” “event socket,” or “socket,” construction is not needed.

“d) Analysis Re Construing “Voice Call Signals” We conclude that it is unnecessary to define “voice call signal.” Patent Owner’s construction would read into the term additional limitations that are for the most part already set forth in the claims: “a switchable mobile communications device capable of . . . voice call communication” (claims 1, 13, 21, 32); “output . . . a voice call signal for transmission . . . over a wireless network” (claims 13, 21, 32); “wherein the mobile communication device is a selected one of a wireless mobile phone and a personal digital assistant equipped with communication capability” (claims 12, 20, 31, 39). Thus the claims require a mobile communications device that is capable of communicating a voice call signal, but do not restrict the voice call signal to only be communicated by a mobile communications device. Likewise, claims 13, 21, and 32 (but not claim 1) require the voice call signal to be transmitted over a wireless network, but do not restrict transmission to only a wireless network, and do not restrict the wireless network to “a network of a wireless network service provider,” as Patent Owner would require.” slip op. at 15

In the latter role, transmitted RFID transponder data appears to an RFID reader to have been transmitted from an ordinary RFID transponder.
