Under 35 U.S.C. § 314(a), we may not authorize an inter partes review unless the information in the petition and the preliminary response “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Upon consideration of the Petition, the Preliminary Response, the Reply, the Sur-reply, and the evidence of record, for the reasons given below we determine the information presented in the Petition demonstrates there is a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one challenged claim of the ’925 patent.” slip op. at 2

Petitioner further asserts that the ordinarily skilled artisan “would have been knowledgeable about audio signal processing techniques, such as gain normalization and dynamic range compression, and software engineering.” Id. At this stage, Patent Owner does not specifically address the level of skill of the ordinary artisan. See generally Prelim. Resp. For purposes of this Decision, we adopt Petitioner’s definition of the level of ordinary skill in the art. On the present record, we are satisfied that this definition comports with the level of skill necessary to understand and implement the teachings of the ’925 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that the prior art itself can reflect appropriate level of ordinary skill in art).” slip op. at 12

      “Patent Owner incorrectly interprets the issued ’925 patent claim terms under BRI. Prelim. Resp. 2. Accordingly, at this stage of the proceeding, we decline to consider Patent Owner’s proposed constructions for claim 1 under the legally incorrect broadest reasonable interpretation standard, which is only applicable during prosecution before a patent examiner. As emphasized above, in interpreting the claims of the ’925 patent, we “us[e] the same claim construction standard that would be used to construe the claim[s] in a civil action under 35 U.S.C. [§] 282(b).” See 37 C.F.R. § 42.100(b) (2023). We further emphasize that we construe claim terms only as relevant to the parties’ contentions and only to the extent necessary to resolve the issues in dispute. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999); Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017). Based on our review of the current record, we determine that no express construction of any term is necessary to resolve this case for purposes of institution. We leave it to the parties to further develop during under the proper Phillips standard applied to IPR proceedings. See Phillips, 415 F.3d at 1313.” slip op. at 14

      “Li teaches away from Petitioner’s proposed modifications to add a plug at each end of connecting component 113. See Prelim. Resp. 39, 41. A “reference does not teach away” if “it merely expresses a general preference for an alternative invention but does not ‘criticize, discredit, or otherwise discourage’ investigation into the invention claimed.” DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009) (quoting In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004)). Li expresses a general preference for connecting first housing 111 and second housing 112 to the two ends of first elastic metal wire 1131 in connecting component 113 by injection molding. Ex. 1004 ¶¶ 29, 35, dependent claims 2 and 7. For example, Li explains that “[o]ptionally, the first housing 111 and the second housing 112 are fixedly connected to both ends of the first elastic metal wire 1131 by injection molding.” Id. ¶ 29. Li does not “criticize, discredit, or otherwise discourage” using a plug to connect a housing to connecting component 113. See, e.g., id. ¶¶ 29, 35. Instead, Li discloses using plugs to mechanically connect components, i.e., to connect rear hook assembly 12 to “the first housings 111 of the two ear hook assemblies 11.” Ex. 1004 ¶ 58, Figs. 2, 9; see Ex. 1003 ¶¶ 57, 117, 122. Li similarly discloses using mechanical connectors comprising a clamping portion that engages with a locking portion to connect components, e.g., to “fix the first housing 111 and the third housing 114 together” and “fix the second housing 112 and the fourth housing 115 together.” Ex. 1004 ¶¶ 44–45. Li identifies these mechanical connectors as alternatives to adhesive bonding and “fasteners such as screws.” Id. ¶ 44; see id. ¶ 59 (identifying plugs as alternatives to “screw fixation”). Hence, we determine Li discloses a variety of ways to connect components in a bone conduction earphone but does not appear to “criticize, discredit, or otherwise discourage” any of those ways. See, e.g., Ex. 1004 ¶¶ 29, 35, 44–45, 58–59, Figs. 2, 9; see Ex. 1003 ¶¶ 57, 117, 121.” slip op. at 45

Cir. 2025) (Obviousness “does not require that a particular combination must be the preferred, or the most desirable, combination described in the prior art in order to provide motivation for the current invention.”); see also KSR, 550 U.S. at 420 (“[T]he problem motivating the patentee may be only one of many addressed by the patent’s subject matter.”). The relevant question is not whether the proposed combination is the most desirable combination available. Rather, it is “whether there is something in the prior art as a whole to suggest the desirability, and thus the obviousness, of the claimed invention.” Honeywell, 124 F.4th at 1355 (citations omitted). Here, Petitioner has identified reasons why it would have been desirable to modify the system of Brooks to include the texted URL link of SARLOC: the caller would not need any special technical skills or equipment; existing smartphone functionality would be capable of collecting the location information; and SARLOC simply represents a specific example of a general concept taught in Brooks, that of exchanging location information through text messages.

Mot. 1, 4. Petitioner represents that “joinder will not negatively impact the Apple IPR trial schedule” and “expressly consents to the existing trial schedule.” Id. at 10; see also id. at 7 (“Proceeding with a consolidated inter partes review would avoid potential inconsistency, promote efficient review of the same claims for the same patent under the same grounds, and would result in a final written decision without delay.”). Petitioner also represents that as “long as Apple remains in the joined IPR, Nintendo remains in a limited ‘silent understudy’ role that does not actively participate in the IPR.” Id. at 8. The record supports Petitioner. In addition, the final written decision in the Apple IPR is due to issue on or before October 15, 2025, with the Oral Hearing complete and no further briefing due. See IPR 2024-00807, Paper 15 (Oral Hearing Transcript); Paper 18, 2–3. Therefore, as Petitioner argues, joinder by Petitioner will have little or no impact on the trial schedule in the Apple IPR.

Ex. 1017, 2421. Thus, contrary to Patent Owner’s assertion, the Examiner did not find Jones 2005 “discloses each limitation of claim 1 of the ’108 patent.” See Prelim. Resp. 39. In other words, the Examiner did not make “the same arguments with respect [to] Jones 2005 publication during the prosecution of the ’340 application.” Id.

      “it “never discloses increasing the percentage of the sequence of interest as compared to any other component of the sample.” Prelim. Resp. 25. But contrary to this assertion, Meyer specifically discloses that a single copy of the broken chain T-primer was found in “16% of the total” raw reads, “slightly more than the expectation (~10%).” Ex. 1006, 9. If the expected 3' end fragments are 10% of the total reads, the combined 5' end fragments and internal fragments would be 90%. By employing the broken chain T-primer, Meyer increased the percentage of the 3' end fragments to 16% of the total reads, which means the combined 5' end fragments and internal fragments would be decreased to 84%. In other words, Meyer discloses increasing the percentage of the 3' end fragments, which contains the broken chain T-primer sequence, as compared to the 5' end fragments and internal fragments. Patent Owner does not explain persuasively why, under such circumstances, enrichment is not met. Patent Owner emphasizes that Meyer “is directed toward improving the error rate of sequencing reads.” Prelim. Resp. 26 (citing Ex. 2021 ¶¶ 124–130); see also id. at 28 (“The ‘homopolymer problem’ that Meyer was trying to fix is an issue caused by the 454 sequencer.”). We agree with Patent Owner on this issue.

      “We do not see a material difference in the parties’ proposed levels of education and work experience. Indeed, although Petitioner asserts that a POSA “would have a PhD or equivalent training,” it allows more work experience to compensate for less education. Pet. 23 (stating that a POSA could have “commensurately less education and more work experience”). We, nevertheless, adopt Patent Owner’s proposal in this aspect because it specifies the years of experience needed. Patent Owner also disputes Petitioner’s proposal that a POSA would have had experience with “implementing and designing library preparation methods 454 and Illumina, the leading NGS platforms in 2012.” Id. at 15 (quoting Pet. 23, emphasis added by Patent Owner removed). According to Patent Owner, “[t]his level of skill inappropriately requires the POSA to be an inventor of library preparation methods.” Id. On this record, we agree with Patent Owner that “experience with implementing and designing library preparation methods 454 and Illumina” is above ordinary skill. We, however, find insufficient Patent Owner’s proposal that “the POSA would have had experience with DNA sequencing methods.” Id. at 15–16 (citing Ex. 2021 ¶¶ 65–68). The challenged claims relate to sequencing methods using a next-generation sequencing (“NGS”) platform. See Ex. 1002, 35:49–51 (claim 1 reciting “sequencing the amplified products comprising the enriched nucleic acid sequence of interest on a massively parallel sequencing platform”). As Patent Owner recognizes, [c]ompared to traditional, Pre-NGS sequencing methods, NGS sequencing utilized a new design that no longer relied upon disassembling and then piecing together a single original template DNA strand. Instead, NGS sequencing now allowed sequenced in the same reaction. With NGS, a user could perform massively parallel sequencing, allowing for elements of the genome to be sequenced in a fast, scalable manner. Prelim. Resp. 4. As such, we disagree with Patent Owner that a POSA only need to “have had experience with DNA sequencing methods” (id. at 15–16) because an artisan with experience with only pre-NGS sequencing methods would not qualify as a POSA. Instead, for purposes of this Decision, we find a POSA would have had a Ph.D. in the field of chemistry, molecular biology, or biochemistry. Alternatively, a POSA would have had a B.S. or M.S. degree with three to five years of experience working in any of those fields. Additionally, the POSA would have had experience with NGS sequencing methods and a working knowledge of how those methods functioned. This definition of a POSA is consistent with the skill level reflected in the disclosures of the ’108 patent and prior art. We further note that neither aspect of the dispute over the skill level affects our decision to institute review.” slip op. at 11

To the extent express construction of “enrich” is necessary, we adopt the plain and ordinary meaning of the term.
