“III. LEVEL OF ORDINARY SKILL IN THE ART Petitioner contends a person of ordinary skill in the art (“POSITA”) would have a Ph.D. degree in biological, chemical or biochemical engineering, molecular biology, or biochemistry and at least two years of experience in the field of utilizing or assessing horseshoe crab zymogen proteins (lysate, purified native and/or recombinantly produced) for endotoxin detection and quantitation. More education could substitute for experience to a certain extent, and vice versa. Pet. 22 (citing Ex. 1003 ¶¶48–49). Patent Owner does not dispute Petitioner’s description of a POSITA in its Preliminary Response. Prelim. Resp. 10. 1 In addition to other changes to Title 35, the AIA introduced amendments to 35 U.S.C. § 102. Because Patent Owner concedes that the ’725 application “contains, or contained at any time, a claim to a claimed invention that has an effective filing date on or after March 16, 2013” (Ex. 1022), the AIA version of § 102 applies to the ’109 patent.

Petitioner did not. Pet. 23– 24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in which a POSA would have understood the prior art, or what a POSA would have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023. See Ariad, 598 F.3d at 1351 (“[T]he [written description] test requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” (emphasis added)).

“Nevertheless, we determine that the contrary evidence Petitioner has cited suffices to establish a reasonable likelihood of success at this preliminary stage of the proceeding. In this regard, we also note Dr. Jain’s testimony — currently unrebutted — that an ordinarily skilled artisan would have known, based on Tokunaga’s sequence comparisons of Factor C proteins, that “certain sequence differences between [Limulus polyphemus] and Tachypleus tridentatus were non-conservative (i.e., potentially giving rise to changes in function in terms of enzymatic activity of Factor C).” Ex. 1002 ¶ 94 (citing Ex. 1022, 157). We likewise note Dr. Jain’s testimony that such artisan would have recognized Tokunaga’s conclusion, regarding “immunological and biochemical properties” of Factor C proteins of the two different horseshoe crab species, to be “based on only gross biophysical-biochemical properties” that are not “granular enough” to predict functional properties such as residual activity in presence of specific ions.

See 37 C.F.R. § 42.64(b)(1) (“Any objection to evidence submitted during a preliminary proceeding must be filed within ten business days of the institution of the trial.”); also compare Fed. R. Evid. 801(c) (defining hearsay as a statement, not made at the current trial or hearing, “offer[ed] in evidence to prove the truth of the matter asserted”), with Fed. R. Evid. 801(d)(2) (excluding from hearsay statement offered against an opposing party where statement was made by “a person whom the party authorized to make a statement on the subject” or by a “party’s agent or employee on a matter within the scope of that relationship and while it existed”). Nevertheless, as discussed above, Petitioner has provided contrary evidence, including statements from Patent Owner’s patent application, suggesting that, “due to the various differences and diversity of biomolecules depending on the genus and species of the horseshoe crab,” it had not been possible “to accurately determine the full-length sequence structure, expression, and function of [Limulus] proteins and genes using conventional methods” more than 20 years after complete gene and amino sequences from two Tachypleus horseshoe crab species had been reported. Pet. 35 (citing, e.g., Ex. 1005 ¶¶ 12–17). Thus, even if we were to take the Frohman Declaration into account, we find that Petitioner has established a reasonable likelihood 28 of success that the ’767 application disclosures did not enable an ordinarily skilled artisan to make and use the invention of the challenged claim without undue experimentation. Furthermore, assuming that the disclosures in ’767 application would have enabled an ordinarily skilled artisan to express recombinant Limulus polyphemus Factor C protein in HEK293, we find Petitioner has established, sufficient for purposes of institution, that the disclosures do not enable an ordinarily skilled artisan to make such a protein exhibiting the “full scope” of the claimed residual activity, without undue experimentation. Patent Owner cites to disclosures in the ’767 application that (1) describe how to produce recombinant Factor C in HEK293 cells and measure residual activity, (2) suggest “Factor C expressed in mammalian cells can have low susceptibility to activity inhibition by ions,” and (3) provide examples where residual activity met the required minimum. Prelim. Resp. 26–27, 32–34. Nevertheless, whether an ordinarily skilled artisan would have been able to make, based on these disclosures and without undue experimentation, a recombinant Factor C protein having residual activity encompassed by claim 21 but higher — even significantly higher — than that achieved in the example, is a fact intensive issue that would benefit from further development during trial.15 See, e.g., In re” slip op. at 28

“On this preliminary record, we agree with Patent Owner that Petitioner’s asserted level of ordinary skill in the art is higher than warranted when Petitioner argues that a person of ordinary skill “further would have had specific experience with implementing and designing library preparation methods.” Pet. 21–22. However, we disagree with Patent Owner that a POSA only need to “have had experience with DNA sequencing methods” (Prelim. Resp. 8) because an artisan with experience with only pre-NGS sequencing methods would not qualify as a person of ordinary skill. Instead, for purposes of this Decision, we find a person of ordinary skill 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. The person of ordinary skill would have had experience with NGS sequencing methods and a working knowledge of how those methods functioned. This definition of a person of ordinary skill is consistent with the skill level reflected in the disclosures of the ’357 patent and prior art.

“May” expresses a possibility. The Specification reflects this interpretation of “may” when it states that “[i]n one embodiment, the organic material is not lyotropic. Thus, the organic material may not be a phospholipid.” Ex. 1001, 8:27–28 (emphasis added). One of ordinary skill would understand from this that the organic material “may not be” a phospholipid if the organic material is not lyotropic. It follows that if the organic material is lyotropic, then the organic material may be a phospholipid. Reading the statement “[t]he organic material may not be . . . a phospholipid” (id. at 8:59–63) in light of the earlier stated possibility that the organic material may be a phospholipid if the organic material is lyotropic, one of ordinary skill in the art would interpret “may not be” as excluding phospholipids under some conditions, not under all conditions. Taking the Specification’s discussion about phospholipids as exemplifying the permissive nature of the word “may,” we are unpersuaded that in stating that “[t]he organic material may not be [PMMA], a polyvinylidene difluoride-containing polymer, such as [PVDF] or PVDF- TrFE-CTFE, or a phospholipid, such as [DHPE]’” (Ex. 1001, 8:59–63), the specification “contains a clear and unmistakable disavowal of the compounds PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE” and “disclaims the listed compounds” from the “organic material” of the claims under all conditions, as Patent Owner argues. Prelim. Resp. 6–7. Moreover, the claims themselves limit the “organic material” only to the extent that it is “barocaloric cooling or heating agent” and can perform in the manner claimed. See Ex. 1001, claim 1, supra. As broadly worded, the claims do not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE per se from the group of organic materials employed by the claimed method. Adopting Patent Owner’s construction would impermissibly import a limitation (i.e., not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE) into the claims. For the reasons stated, at this stage of the proceeding, we agree with Petitioner’s broad construction of “organic material.” We do not adopt Patent Owner’s proposed construction whereby PMMA, PVDF, PVDF- TrFE-CTFE, and DHPE are excluded from the scope of the claim term “organic material.” The parties are invited to address this issue further during trial, if desired. slip op. at 11

Whether or not other patients were treated or enrolled in the study does not detract from this teaching.3 Accordingly, we are persuaded by Petitioner that, on this record, the MSI-H Study Record discloses each element of claim 1. In view of the above, we determine that Petitioner has sufficiently shown a reasonable likelihood of establishing that the MSI-H Study Record anticipates claim 1. Patent Owner at this stage does not offer any arguments addressing Petitioner’s substantive showing.” slip op. at 16

“not disclose the limitation of “in response to determining that the colorectal cancer is microsatellite instability high or DNA mismatch repair deficient, treating a human patient having colorectal cancer that is microsatellite instability high or DNA mismatch repair deficient with a therapeutically effective amount of pembrolizumab,” the record before us supports this limitation being rendered obvious by Pernot and the MSI-H Study Record. Specifically, because Pernot teaches that colorectal cancer patients are good candidates for immunotherapy, the evidence of the current record shows that one of ordinary skill in the art would have had a reason to use to PD-1 inhibitors to treat colorectal cancers. Ex. 1006, 3741; Ex. 1003 ¶ 136. Additionally, the focus in the MSI-H Study Record on a clinical study treating colorectal cancer patients who had been determined to be MSI-H with pembrolizumab indicates that it would have been obvious to test for this condition before treatment. The additional references discussed by Petitioner contribute further to a reasonable likelihood that Petitioner will prevail. For example, Libson reports the successful treatment of a colorectal cancer patient having MSI-H status with a PD-1 inhibitor (Ex. 1057, 463-64) and Champiat discusses evaluating the clinical activity of PD-1 agents in DNA mismatch repair, such as MSI+, colorectal cancer (Ex. 1032, e27817-5). Pet. 44 (citing Ex. 1003 ¶ 49). Thus, based on the current record, we determine that Petitioner presents a reasonable likelihood that the method of claim 1 would have been considered obvious by one of ordinary skill in the art. Accordingly, in view of the above, we are persuaded that there is a reasonable likelihood that Petitioner will prevail with respect to at least one claim challenged under Ground 2 in the Petition.” slip op. at 21

“22. Our research group eventually approached Merck. Merck agreed in early 2013 to supply its then-unapproved anti-PD-1 antibody, MK-3475 (pembrolizumab) for use in the study. It was, however, the research team at Hopkins who secured IRB approval, conducted, and paid for the study. On June 12, 2013, the solicitation for patients was first posted on clinicaltrials.gov (Exhibit D). In my mind, the four arms allowed us to try to get at an answer to a question to which we did not know the answer-specifically whether or not patients with MSI-high or MMR deficient tumors would exhibit an improved response when treated with MK-3475, compared with the more common MSS [microsatellite stable] or MMR proficient colon cancers. Thus, the trial covered all patients with colon cancer, MSI and MSS, but separated into two groups. 23. The preliminary results of this study demonstrated clinical responses at an unexpectedly high rate (>50% objective response rate) in the MSI-high (MMR deficient) arm but not in the MSS (MMR proficient) arm. (Ex. 1002, 270–271.) This affidavit, submitted during prosecution of the ’974 patent, supports the argument that an improved outcome of treating a patient with a tumor exhibiting an MSI-high or a MMR deficiency status with pembrolizumab compared to similarly treating a patient without an MSI-high or a MMR deficiency status, a recited in claim 1, is an inherent result. Patent Owner does not dispute this result in the Preliminary Response. See Prelim. Resp. 7 (“The ’974 Patent reports that mismatch repair-deficient colorectal cancers (i.e., MSI-H CRC) had an immune-related objective response rate and immune-related progression-free survival rate of 40% and 78%, respectively—a huge improvement compared to the 0% and 11% rates found in mismatch repair-proficient colorectal cancers (i.e., MSI negative CRC).”).” slip op. at 17

“Petitioner argues that Pernot teaches treating colorectal cancer and that, therefore, because the MSI-H Study Record is directed to a clinical study treating colorectal cancer in a patient whose cancers are MSI-H with pembrolizumab, which is an anti-PD-1 antibody, one of ordinary skill in the art knowing the teachings of the MSI-H Study Record would have considered the teachings of Pernot.
