“Paper 34, 1 (requesting “Director Review of the Director’s August 22, 2025 Decision Referring the Petition to the Board (‘Referral Decision’)”). Patent Owner argued that institution of IPR2025-00687 and IPR2025-00688 “should be discretionarily denied.” Id. at 5. Petitioner opposed. Paper 37. The Director granted review and found that “granting institution of two petitions that each challenge the same claims of the ’370 patent and ’218 patent 2” was an “abuse[] of discretion.” Paper 40, 1. The Director remanded the cases “to the Board panel to determine which of the two petitions challenging each of the ’370 and ’218 patents to institute.” Id. at 3. Pursuant to the Director’s instruction that we choose only one of the two petitions challenging the ’370 patent to institute, and for the reasons set forth below, we choose to institute review of the ’370 patent in this Petition, and not in IPR2025-00688.” slip op. at 3

“appear to be that Patent Owner specifies that the POSA’s knowledge and experience may include optical sensors and that the POSA may have a degree emphasizing software. We do not deem these differences material, particularly because the optical sensors and technologies at issue are those used in physiological monitoring technologies and both parties agree that the POSA would have a working knowledge of physiological monitoring technologies. Ex. 1003 ¶ 24; PO Resp. 11. We find the additional specificity of Patent Owner’s definition to be helpful. In addition, Patent Owner’s definition appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’507 patent. Accordingly, we adopt Patent Owner’s proposed definition of the person of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Our inability to find a teaching of averaging in Mendelson is consistent with the testimony of Drs. Kenny and Duckworth. Dr. Kenny testifies that “there is simply no disclosure in Mendelson itself of any summing or averaging of collected signals.” Ex. 1083 ¶ 23. And in his deposition, Dr. Duckworth was unable to identify any express disclosure of averaging in Mendelson. See Ex. 1087, 103:9–114:11 (confirming that certain aspects of his declaration testimony relating to averaging of signals are not discussed in Mendelson).

And while Brown does teach a desire to form “substantially pure” compounds, Brown focuses on “at least about 90 wt.%” of the compound, then lists specifically “about 90, about 91, about 92, about 93, about 94, about 95, about 96, about 97, about 98, about 99 and about 100% wt. %.” Ex. 1003 ¶ 97.

That is not, however, the standard for inherency. It must be the necessary result, not a possible expected result. The Federal Circuit in Par explained that: Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient. If, however, the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be regarded as sufficient.” slip op. at 28

As such, Patent Owner cannot show non-obviousness “by attacking references individually.” In re Keller, 642 F.2d 413, 426 (CCPA 1981). Patent Owner argues that “because Parameswaran used pyrosequencing on the surface of beads in a Roche 454 sequencer, it does not disclose the formation of clusters.” Prelim. Resp. 21 (citing Pet. 31). Petitioner, however, relies on Gloor for teaching “amplifying said nucleic acid templates on a surface of a flow cell thereby to form clusters.” Pet. 31–32. Patent Owner does not challenge this reliance. See generally Prelim. Resp. Patent Owner contends that Petitioner “equat[es] the claimed chimeric sequences with ‘mismatched’ or ‘misassigned’ sequences containing an ‘unexpected’ pair of forward and reverse barcode motifs identified in Parameswaran.” Prelim. Resp. 18–19. But, according to Patent Owner, “Petitioner does not point to any disclosure in Parameswaran identifying these “mismatched” motifs as chimeric sequences—as opposed to mere sequencing or sample handling error—nor does Petitioner cite any disclosure in Parameswaran regarding such sequences resulting from cross-over events.” Id. at 19. We find Patent Owner’s characterization of Petitioner’s argument inaccurate. As we understand it, Petitioner does not “equat[e]” the claimed chimeric sequences with “mismatched” sequences in Parameswaran. Instead, as Patent Owner acknowledges, “Petitioner argues that ‘sequences with mismatched barcode motifs’ in Parameswaran ‘include chimeric sequences resulting from cross-over events.’” Id. (quoting Pet. 32) (emphasis added).” slip op. at 14

“On the current record, there is no controversy over the meaning of any of the claim terms and neither party identifies a claim construction that would impact our analysis. We therefore find that, at this stage of the proceeding, there are no terms that need claim construction. See, e.g., Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (“[C]laim terms need only be construed ‘to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

“VIII. LEVEL OF ORDINARY SKILL IN THE ART Petitioner asserts (without opposition): A person of ordinary skill in the art (“POSA”) at the time of invention would have a working knowledge of microbiology and would have been involved in developing testing methodologies for analysis of samples such as food products (“validation methodologies”). The POSA would most likely have an advanced degree in microbiology, food science, or animal science and at least two years of work experience but may alternatively have a bachelor’s degree in those areas and at least four years of experience with validation methodologies. The POSA would have been familiar with relevant scientific literature and industry regulations, directives, and guidelines relating to validation methodologies.” slip op. at 8
- Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Instituted
“Determining whether claims are anticipated involves a two-step analysis. The first step involves construction of the claims of the patent at issue. Claim construction is a question of law reviewed de novo.” In re Aoyama, 656 F.3d 1293, 1296 (Fed.Cir.2011). “The second step [of an anticipation analysis] involves comparing the claims to the prior art. Anticipation is a question of fact reviewed for substantial evidence.” In re Aoyama, 656 F.3d at 1296. “A prior art reference anticipates a patent claim under 35 U.S.C. § 102(b) if it discloses every claim limitation.” In re Montgomery, 677 F.3d 1375, 1379 (Fed. Cir. 2012). A reference may anticipate inherently if a claim limitation that is not expressly disclosed “is necessarily present, or inherent, in the single anticipating reference.” Verizon Servs. Corp. v. Cox Fibernet Va., Inc., 602 F.3d 1325, 1337 (Fed. Cir. 2010). slip op. at 9
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundInstituted
“The motivation-to-combine analysis is a flexible one. “[A]ny need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements in the manner claimed,” [but the] “analysis ‘need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.’” Intel Corp. v. PACT XXP Schweiz AG, 61 F.4th 1373, 1379–80 (Fed. Cir. 2023) (quoting KSR, 550 U.S. at 418, 420 (emphasis added)). “[I]f there’s a known technique to address a known problem using ‘prior art elements according to their established functions,’ then there is a motivation to combine,” because KSR explains that “if a technique has been used to improve one device [or method], and a person of ordinary skill in the art would recognize that it would improve similar devices [or methods] in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” Id. at 1380 (quoting KSR, 550 U.S. at 417; and Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 797 (Fed. Cir. 2021)). If addressing a known problem, the prior art combination need not be “the best option, only . . . a suitable option.” Id.

“with the computer program 110.” Ex. 1005, 3:54–55. Thomas describes that (1) the “collected data is then stored in the database 130,” (2) the collected “data is stored in a data structure, generally referred to as a user’s profile,” and (3) the collected “data is logically linked to an event, or situation, that initiated the user’s input.” Id. at 3:56–61. Thomas describes creating or establishing a user profile by simulator 120 recording “the user’s decision/input” and storing “the user’s input in the field or sub-profile associated with the particular situation and/or event.” Id. at 4:67–5:5, Fig. 6. Patent Owner does not dispute Petitioner’s showing for element [1.3]. Also, contrary to Patent Owner’s arguments, we must consider what Thomas discloses rather than whether Thomas uses the exact claim term “instruction sets.” Cf. Gleave, 560 F.3d at 1334 (a reference does not have to satisfy an ipsis verbis test to disclose a claimed element). For these reasons, we are not persuaded by Patent Owner’s argument that Thomas does not “mention instruction sets” or “anything related to an instruction set.” PO Resp. 36–37; PO Sur-reply 17.” slip op. at 42
