“inter partes review may not be instituted “unless . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Under § 314, the Board may not institute review on fewer than all claims challenged in the petition. SAS Inst., Inc. v. Iancu, 584 U.S. 357, 371 (2018). If the Board institutes a review, it will institute “on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a). Upon consideration of the Petition, the Preliminary Response, and the evidence of record, for the reasons set forth below, we conclude the Petition demonstrates a reasonable likelihood that Petitioner would prevail in showing the unpatentability of at least one challenged claim in the ’679 patent.

“In an inter partes review, the burden of persuasion is on the petitioner to prove ‘unpatentability by a preponderance of the evidence,’ 35 U.S.C. § 316(e), and that burden never shifts to the patentee.” In re Magnum Oil Tools Int’l Ltd., 829 F.3d 1364, 1375 (Fed.

A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious to a person of ordinary skill in the art at the time the invention was made. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007) (quoting 35 U.S.C. § 103(a)). Obviousness is resolved based on underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness, i.e., secondary considerations. Graham v. John Deere Co., 383 U.S. 1, 17– 18 (1966). A party who petitions the Board for a determination of obviousness must show that “a skilled artisan would have been motivated to invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” Procter & Gamble Co. v.

Patent Owner also contends, however, that the Petition relies on a “novel claim construction” of limitations [1.4.1] and [1.5.1]—“second [third] hardware processor with a plurality of processing cores”—to support Petitioner’s obviousness argument. Id. at 11–12.8 Patent Owner challenges the Petition’s reliance on “single core processors on different chips,” such as the Power3 single-core processors of the Symmetric Multi- Processor (“SMP”) configuration disclosed in the RS6000 reference, as a disclosure of limitations [1.4.1] and [1.5.1]. Id. Patent Owner contends that such single-core processors on different chips do not satisfy limitations [1.4.1] and [1.5.1] because the ’034 patent “claims only multicore processors.” Prelim. Resp. 5 (citing Ex. 1001, 7:15–27). Petitioner responds in part as follows: To the extent PO is implicitly arguing that RS6000’s “four, eight, twelve, or sixteen 375 MHz 630FP 64-bit processors” do not teach the recited “cores,” Patent Owner’s argument excludes embodiments described in the ’034 patent’s specification. The ’034 patent describes “[p]rocessor cores [as] generally independent microprocessors.” Ex.1001, 5:14–15. Patent Owner’s attempt to exclude RS6000 from the scope of the claims 8 Pursuant to the Board’s Order on Related Matter Updates (Paper 14), the parties filed the September 26, 2025 Claim Construction Order entered in the co-pending District Court litigation in this proceeding. Ex. 1085. The District Court Claim Construction Order did not construe the claim phrase “hardware processor with a plurality of processing cores.” Id. patent where the processor has independent microprocessors. Patent Owner’s attempt to distinguish RS6000’s Symmetric MultiProcessor as a “configuration” (Paper 8, 24) also fails because a “Symmetric MultiProcessor configuration” is no different than the ’034 patent’s description of a configuration of independent microprocessors. Id. Paper 9, 30.9 It is apparent there is a dispute over the plain meaning of Limitations [1.4.1] and [1.5.1], “a second [third] hardware processor with a plurality of processing cores,” recited in the independent claims.10 The parties are ordered to propose and support a particularized plain meaning or other construction of Limitations [1.4.1], [1.5.1], and [30.1.2] in their briefs. The parties are ordered to analyze the relevant claim language and cite to the specification and prosecution history in support of their claim construction, where applicable, with particular attention to the description of a hardware processor with a plurality of processing cores in the ’034 patent.

“(1) Analogous Art Our reviewing court has stated that “[t]wo separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor's endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) (citations and internal quotes omitted). While these two criteria are helpful in many instances, we must not lose sight of the key question at hand: what is “prior art” as that term is used in 35 U.S.C. § 103(a)? References that are “too remote to be treated as ‘prior art’” are excluded from the obviousness analysis. In re Sovish, 769 F.2d 738, 741, 226 (Fed. Cir. 1985). The non-analogous art test provides helpful insight on the underlying question of what is “prior art” within the meaning of the statute; we should not, however, be blind to the reality of the circumstances of the case before us. In re Wood, 599 F.2d 1032, 1036 (CCPA (1979). Nor should we adhere to rigid and mandatory formulas that overly limit the inquiry. KSR Int’l Co., 550 U.S. at 419.” slip op. at 22

“Summary Based upon the record as presently developed, we conclude that Petitioner has met its burden of showing a reasonable likelihood of showing at trial that at least claim 1 of the ’370 patent is obvious over the cited prior art. Because we determine that Petitioner has demonstrated a reasonable likelihood of success at trial in showing that at least one claim is unpatentable on at least one of the stated Grounds, we institute inter partes review of all challenged claims of the ’370 patent, based on all of the remaining grounds identified in the Petition.

“appears to be generally consistent with the level of skill presented in the cited prior art. See generally, e.g., Exs. 1005–1008; see also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself may reflect an appropriate level of skill in the art). However, at this point we reject the portion of Petitioner’s proposed definition that includes having “access to other individuals with that knowledge and experience,” as not reflecting the individual level of skill of a given skilled artisan. See, e.g., Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986) (holding that “[t]he person of ordinary skill is a hypothetical person who is presumed to be aware of all the pertinent prior art. The actual inventor’s skill is not determinative”) (emphasis added, footnotes omitted). Consequently, and for the purposes of this Decision, we adopt Petitioner’s proposed definition as defining a person of ordinary skill in the art as a person who would have had “a Ph.D. in immunology, molecular biology, cellular biology, or a similar field, or an M.D. with similar experience, and would further have had at least five years of experience with antibodies and antibody engineering.”” slip op. at 6

“We find, based upon the present record and for the purposes of this Decision, that Petitioner has sufficiently established that a person of ordinary skill in the art would have been motivated to combine the teachings of Wei and Liu to determine the activity and suitability of Liu’s humanized anti- EGFR antibodies in an ADC. We acknowledge that Liu is silent regarding the pH selectivity or tissue preference of its binding affinity, but Patent Owner points to no prior art reference that would have informed a skilled artisan upon this point or that would have discouraged a person of ordinary skill in the art from combining the references. See fn.7, supra. And, even if a skilled artisan might have recognized that Liu’s humanized cetuximab might have been potentially problematic if it failed to show pH-selective activity like Wei’s Y104D, the mere fact that some disadvantage may come with an advantage when combining prior art does not foreclose their combination under § 103. Medichem, S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). In the instance of Liu’s humanized anti-EGFR antibody, a person of ordinary skill in the art would have recognized that its advantages (enhanced activity against tumor cells compared to chimeric cetuximab, thus requiring smaller dosages) could balance or outweigh its possible disadvantages (e.g., possible activity against non-tumor cells). Furthermore, it is in the nature of scientific research to continue to try new substitutions in drug therapy, even if a promising candidate has been discovered. As the Supreme Court stated in KSR: When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under § 103. 550 U.S. at 421.” slip op. at 39

“We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012).

We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

“Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38
