      “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. (quoting Intel, 21 F.4th at 800 (emphasis original)).” slip op. at 13

      “We agree with Patent Owner that the term “lots” does not require construction because on the current record, there is no controversy over the meaning of the term, and neither Petitioner nor Patent Owner identify any way that claim construction may impact our decision. We also agree with Patent Owner that the ’771 patent provides definitions that guide the understanding of the term “lots” including: The term “test lot” or “reportable lot” as used herein to refer to an assemblage of one or more specimens of a medium or process (e.g. assemblage of specimens of air, water, solids or of products of a production process, etc.), where such assemblage can be sampled by taking portions of the one or more specimens thereof, and where the one or more specimens of the assemblage are operationally linked in a manner (e.g., proximity, time, process step, etc.) whereby information derived about sampled portions is operationally applicable to all specimens of the assemblage, and thus to the test lot. In particular instances, portions are synonymous with specimens. Ex. 1003, 5:43‒54. The ’771 patent similarly provides definitions for “product portion,” “test lot sample,” and “composite lot-unit” that provide significant guidance and clarity as to the meaning of these terms.

      “III. CONCLUSION After considering the evidence and arguments presented in the Petition, we determine that Petitioner has demonstrated a reasonable likelihood of success in proving that at least one challenged claim of the ’143 Patent is unpatentable. In particular, because Petitioner has demonstrated a reasonable likelihood that at least one claim is rendered obvious by the asserted combinations of ICMSF, Hughes, and Price, we institute inter partes review on all grounds set forth in the Petition. At this stage of the proceeding, the Board has not made a final determination as to the patentability of any challenged claim or the construction of any claim term. Thus, our view with regard to any conclusion reached in the foregoing could change upon consideration of Patent Owner’s merits response and completion of the record.” slip op. at 54

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

      “validation” as used herein with respect to production lots refers to determining that a particular sample tests negative using the detection assay. Where a modular composite sample tests negative, all single-unit production lot samples comprising the composite sample are validated along with the respective single-unit production lots, which are thus cleared for release. Where a modular composite sample tests positive, individual single unit production lots may nonetheless yet be validated if particular respective single-unit production lot samples test negative. Ex.1002, 7:15–24 (emphasis added). The above text expressly equates “validation” to a determination that “a particular sample tests negative.” The initial definitional sentence makes no mention of “cleared for release” as necessary for “validation.” The subsequent sentence refers to “cleared for release” in the more limited situation where a particular composite sample “tests negative all single-unit production lot samples,” and, even then, the “cleared for release” language indicates a separate step that may happen after the samples are “validated.” slip op. at 21

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “On the current record, we are not persuaded that Petitioner has insufficiently articulated a motivation to combine or modify the asserted references. With respect to Ground 1, for example, Petitioner contends that one of ordinary skill in the art would have been motivated to modify ICMSF based on Gombas under the teaching-suggestion-motivation test so portions of the enriched, retained samples are further tested after a positive test of a composite sample by the same protocol, with a reasonable expectation of success for efficient validation. See § XII-A-1-h supra; Dickson ¶¶ 417-19. Pet. 53–54. Petitioner further argues that ordinarily skilled artisan would have sought to improve[] ICMSF with the similar methods of Gombas to yield efficient validation, which is a predictable result. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). In this combination, a POSA would have simply substituted steps of ICMSF, as described above, with those of Gombas so portions of the enrichment cultures are retained and are further tested after a positive test of a composite sample by the same protocol for predictably efficient validation. MPEP § 2143(I)(B); Dickson ¶ 420. Id. at 53. As such, the Petition provides specific reasons to combine ICMSF and Gombas that are consistent with the flexible test recited in KSR, including the benefit of efficient validation of the test and that the combination is a simple substitution of steps. As KSR notes, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 US at 417. Here, Petitioner has made its reasons to combine explicit. See Pet. 53–” slip op. at 47

A party who petitions the Board for a determination of obviousness must show that “a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” Procter & Gamble Co. v.
