“On the current record, the evidence shows it is more likely than not that the claims of the ’035 patent fail to satisfy the written description requirement because they “recite a description of the problem to be solved while claiming all solutions to it and . . . cover any compound later actually invented and determined to fall within the claim’s functional boundaries— leaving it to the pharmaceutical industry to complete an unfinished invention.” Ariad, 598 F.3d at 1353. Accordingly, on the current record, we find that Petitioner has demonstrated that it is more likely than not that the ’035 patent does not comply with the written description requirement. Similarly, the current record does not appear to provide evidence of possession of the full scope of the claims of the ’035 patent in the ’731 application or any of the subsequent divisional or continuation applications leading to the ’035 patent that claim priority to the ’731 application (which appear to all have similar specifications) for the reasons given above.10 Therefore, the ’035 patent might not receive the benefit of priority to the earlier filed applications, and based on this preliminary determination, is eligible for post-grant review” slip op. at 30

“1 requires a causal relationship wherein the patient must be tested for MSI-H and, if he or she is determined to be MSI-H or dMMR, then the patient is treated with 10 mg/kg of pembrolizumab every 14 days. We further agree that this relationship is different than the use of the term “after” in claims 7, 20, and 27, wherein patients must be treated with a different cancer therapy, and wherein the cancer must have later progressed for the treatment to be within the scope of these claims. (Ex. 1001, 25:66–7, 26:44–46, 26:63–64.) In claim 1, a biological sample from the patient must be tested to determine if the cancer is MSI-H and, if so, the patient is treated with a therapeutically effective amount of pembrolizumab.

“raised by this overlap, but given the circumstances, it does not effectively mitigate them. First, the disputed issues for Petitioner’s ODP defense are the same or substantially similar to those for the obviousness grounds in the Petition, but the Sotera stipulation does not prevent Petitioner from litigating those issues before both the district court (as part of its ODP defense) and here in the event an IPR is instituted.19 Second, the MDL proceeding 19 ODP or nonstatutory double patenting is, as the name implies, not premised on any statute.

“What is missing from Petitioner’s stated motivation for modifying the array of Cantor is a reason why a POSA would seek to correlate the identification sequence with a location on the array at all. Prelim. Resp. 72. Indeed, the location of a bead on the substrate is not pertinent to the analysis disclosed in Cantor. Ex. 2002 ¶ 172; see also id. at ¶ 31 (Cantor “does not relate to the [spatial] analysis of tissue samples . . . .”). “[O]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015). Here, Cantor fails to teach or suggest capture probes distributed randomly on a substrate comprising a nucleic acid sequence that identifies a unique location on the substrate as required by the challenged claims, and Petitioner fails to adequately articulate why a person of ordinary skill in the art would have modified Cantor to make the recited capture probes. In view of the above, we find that, on this record, Petitioner has failed to establish that Cantor teaches or suggests each element of the challenged claims. Accordingly, we determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on its challenge that any of claims 1, 3, 6, 10, 11, 16, 18, 21, 24–26, and 30 would have been obvious over Cantor.” slip op. at 20

“What is missing from Petitioner’s stated motivation for modifying the array of Cantor is a reason why a POSA would seek to correlate the identification sequence with a location on the array at all. Prelim. Resp. 72. Indeed, the location of a bead on the substrate is not pertinent to the analysis disclosed in Cantor. Ex. 2002 ¶ 172; see also id. at ¶ 31 (Cantor “does not relate to the [spatial] analysis of tissue samples . . . .”). “[O]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” Belden Inc. v.

Pet. 52–60. Having considered the parties’ positions and evidence of record, however, we agree with Patent Owner’s written description analysis, summarized above, and find (1) that the ’124 Provisional provides adequate written description support for each of the challenged claim elements; (2) that the ’138 patent’s priority chain is intact; and (3) that the ’138 patent is therefore entitled to the priority date of April 5, 2010.

Petitioner adopts the following definition of a person of ordinarily skill in the art (hereafter, sometimes “POSITA”) of the ’967 patent proposed by Patent Owner in the Avery Dennison litigation: [A]t least a bachelor’s degree in electrical engineering, computer science, or computer engineering, or a related discipline, and at least five years of experience which would consist of, A, designing, developing, evaluating and/or using RFID or other AIDC [automatic identification and data capture] technologies in inventory management, unique object identification, and/or security; or B, studying and conducting research related to RFID technologies and using RFID and other AIDC technologies in inventory management, unique object identification, and/or security. Pet. 6 (citing Ex. 1030, 707:3–13). Patent Owner does not offer a definition of an ordinarily skilled artisan of the ’967 patent at this time. See generally Prelim. Resp. Based on the information presented, we find that the asserted prior art itself is sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself can reflect the appropriate level of ordinary skill in the art). To the extent a more precise definition is required, we apply Petitioner’s unopposed proposed definition for purposes of determining whether to institute review because it is consistent with the disclosures of the asserted prior art references and the problems addressed in the ’967 patent.” slip op. at 17

“Petitioner proposes the following claim constructions: “an allocated block of serial numbers” as “a pre-authorized range of binary serial numbers” and “uniquely corresponding” as the “term’s plain and ordinary meaning, consistent with the articulation of the plain and ordinary meaning” in the Avery Dennison litigation. Pet. 8–12. As to the remaining claim terms, Petitioner applies the district court’s constructions in the Avery Dennison litigation. Id. at 12 (citing Ex. 1028). Patent Owner applies the following constructions that were entered during in the Avery Dennison litigation: “object class information space” as “data field within the memory of the RFID integrated circuit chip for information identifying the class of an object, such as a company prefix, item reference code, partition value, and/or filter value,” “unique serial number space” as “data field within the memory of the RFID integrated circuit for information identifying a unique serial number,” “being assigned a limited number of most significant bits” as “includes a limited, predefined sequence at the leading end,” “remaining bits of lesser significance” as “the remaining lower order bits at the trailing end,” “is encoded with one serial number instance” as “has stored within it one serial number instance,” “an allocated block of serial numbers” as “a pre-authorized range of serial numbers,” and “uniquely corresponding” as its plain and ordinary meaning. Prelim. Resp. 32. For purposes of resolving whether to institute trial, we adopt and apply the interpretations stated in the district court’s claim construction order and applied by the Federal Circuit on appeal, Ex. 1028.11 See 55 F.4th 900, 908–909, 912–913 (Fed.

“IBM200 and Kuhno would have made it obvious for a POSITA to commission RFID tags with unique serial numbers partitioned into MSBs and bits of lesser significance. See Pet. 34–39; Ex. 1005 ¶¶ 167–176. However, on this record, Petitioner has not sufficiently shown that the POSITA, having read IBM200 and Kuhno, would have been led to create a serial number space in which the limited number of “most significant bits” uniquely corresponds to those bits assigned to an allocated block of serial numbers, as recited in limitation [f].” slip op. at 25
