“A POSA at the time of the alleged invention would have at least an advanced degree (e.g., a Master’s or Ph.D.) in biochemistry, process chemistry, protein chemistry, chemical engineering, molecular and structural biology, biochemical engineering, or similar disciplines; several years of post-graduate training or related experience (including industry experience) in one or more of these areas; and two or more years of experience in the production of bispecific antibodies.

At this point, we accept and use Petitioner’s proposed, and unopposed, definition of the ordinarily skilled artisan. It appears that Petitioner’s proposed definition comports with the level of skill in the art reflected in the prior art of record and the ’286 patent, itself. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“the prior art itself [may] reflect[] an appropriate level” as evidence of the ordinary level of skill in the art) (quoting Litton Indus.

“The ’286 patent uses the term “heavy chain” or “heavy chains” repeatedly; however, we find no express definition of the term. See generally Ex. 1001. Rather, the ’286 patent uses the term “heavy chain” in relation to antibody structure in a way that suggests the term is standard and well known in the art. See, e.g., id. at 3:19–59 (Background). The parties’ briefing on the technology reinforces this fact. See Pet. 5–14 (“The basic structure of natural IgG comprises four protein chains—two identical heavy chains (shown in red) and two identical light chains (shown in blue)—which are arranged in a Y-shaped configuration: . . . (EX1013, 112-13; EX1002, ¶¶23-30.)”); Prelim. Resp. 3–4 (“Natural or wild type Igs have a particular structure made of two identical light (L) chains and two identical heavy (H) chains. See EX2008 at ¶ 23. Each Ig heavy chain consists of three constant domains (CH1, CH2, and CH3) and one variable domain (VH), which is also isotypes, or a functional derivative and/or fragment of these. In a preferred embodiment, Ig-like molecules are produced that are antibodies of the IgG isotype because IgG antibodies e.g. have a longer half life as compared to antibodies of other isotypes. Ex. 1001, 11:9–21. As noted above (see supra Section I.C), IgG antibodies’ heavy chains have three constant domains, but IgE and IgM have four. Thus, Patent Owner’s argument that heavy chain means one variable and three constant domains, and two differently-binding Fab arms, ignores embodiments of the invention. consistent with the definition of heavy chain in the ’286 Patent. See EX2008 at ¶ 24; EX1001 at 11:58–66.”). This is also how the ’286 patent generally uses the term. See Ex. 1001, 11:58–12:1. But, the Specification does not limit its embodiments to only IgG antibodies because it also describes that the invention may be “IgG1, IgG2, IgG3, IgG4, IgA, IgE, and IgM” type antibodies, and fragments. Ex. 1001, 11:9–21; see also supra n.10 (quoting the ’286 patent’s definition of antibody). Other embodiments would not necessarily have the heavy chains as argued by Patent Owner. There is no evidence of record that the ’286 patent’s claims or the Specification generally use or limit the term “heavy chains” (or “heavy chain”) in any way deviating from its ordinary and customary meaning in the art. Therefore, at this stage of the proceeding, we decline to expressly interpret this claim language. 2. Summary on Claim Construction At this stage of the proceeding, we expressly construe no claim terms and give each claim term the ordinary and customary meaning it would have had to the person of ordinary skill in the art as of the invention date. See Nidec Motor Corp., 868 F.3d at 1017. If either party intends to further argue claim construction at trial, they should do so in a clearly designated section of their briefing so as to expressly identify such arguments. See, e.g., 37 C.F.R. § 42.104(b)(3) (content of petition); see also Board’s Consolidated Trial Practice Guide (CTPG) at 46, 48–45 (Nov. 2019).12 Claim construction arguments should not be relegated to patentability arguments on the facts.” slip op. at 16

“In brief summary, these limitations require one CH3 heavy chain to have a positive amino acid substituted in place of a neutral one, the other CH3 heavy chain to have a negative amino acid substituted in place of a neutral one, and that when the heavy chains are expressed by culturing the host cell these positive and negative amino acids interact and the antibody produced is a heterodimeric antibody. Petitioner asserts that Lazar expressly teaches engineering two CH3 domains so that, when expressed, they interact and form a heterodimeric CH3 interface by making neutral-to-positive and neutral-to-negative amino acid substitutions at known interacting residues on each CH3 domain, e.g., S364E (changing neutral serine to negative glutamic acid at residue 364) on one CH3 domain, and L368K (changing neutral leucine to positive lysine at residue 368) on the other CH3 domain; or T366D (swapping neutral threonine for negative aspartic acid at residue 366) on one CH3 domain and L351K (swapping neutral leucine for positive lysine at residue 351) on the other CH3 domain; that these residues were known in the art to be respective interfacing contact residues; that these modifications favor Fc heterodimerization; and that they result in a heterodimeric antibody (proof-of-concept shown by synthesizing and screening).

“Patent Owner further argues Nakazawa teaches away from Petitioner’s asserted modification in which Glaug’s lower non-perforated layer is added to Nakazawa’s diffusion sheet. Prelim. Resp. 42. Specifically, Patent Owner argues Nakazawa teaches that its embodiment in which the second absorbent material is wrapped in a hydrophilic sheet has the advantage of preventing leakage of super absorbent polymer (“SAP”) from the second absorbent material without impeding permeation of excretory fluid through the hydrophilic sheet. Id. at 43 (citing Ex. 1008 ¶ 85, Fig. 15). Patent Owner further relies on Petitioner’s argument that Nakazawa’s hydrophilic layer is analogous to the lower non-perforated layer in Glaug. Id. (citing Pet. 93–94). Therefore, Patent Owner argues, Nakazawa teaches that Glaug’s fluid acquisition system would impede permeation of fluid rather than promote it. Id. Patent Owner’s teaching away argument is unavailing based on the current record. Patent Owner improperly relies on Petitioner’s contention in its anticipation challenge based on Nakazawa, and characterizes it as an argument about Glaug. As further discussed in Section II.G below, Petitioner’s anticipation challenge is based on analogizing Nakazawa’s hydrophilic sheet to a core wrap feature identified in Patent Owner’s infringement contention in parallel district court litigation. See Pet. 92–93. Contrary to Patent Owner’s argument, Petitioner’s obviousness contention does not argue Nakazawa’s hydrophilic layer is analogous to Glaug’s nonperforated fibrous layer. Because Patent Owner is not properly characterizing Petitioner’s obviousness contention, Patent Owner’s teaching away argument is not persuasive.” slip op. at 24

Less work experience may be compensated by a higher level of education, such as a master’s degree. Pet. 6 (citing Ex. 1003 ¶¶ 28–30). In its Preliminary Response, ParkerVision does not address TI’s assessment of the level of skill in the art. See Prelim. Resp. At this stage of the proceeding, we adopt TI’s uncontested assessment of the level of skill in the art because it is consistent with the ’342 patent and the asserted prior art.” slip op. at 13

“Under 35 U.S.C. § 324(a), a post-grant review may be instituted only if “the information presented in the petition . . . demonstrate[s] that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” Post-grant review is available for patents that issue from applications that at one point contained at least one claim with an effective filing date on or after March 16, 2013. See Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), §§ 3(n)(1), 6(f)(2)(A). After considering the briefing and the evidence of record, for the reasons set forth below, we determine that Petitioner has shown that the ’947 patent is eligible for post-grant review, and has shown it is more likely than not that at least one challenged claim of the ’947 patent is unpatentable under § 324(a). Accordingly, we institute a post-grant review of the challenged claims of the ’947 patent.” slip op. at 2

“Petitioner contends that a person of ordinary skill in the art “would have a B.S. degree in Electrical Engineering, Physics, Chemistry, or an equivalent field, and at least 2-3 years of academic or industry experience in engineering related to optical sorting systems.” Pet. 17 (citing Ex. 1009 ¶ 21). Patent Owner did not file a Preliminary Response to the Petition and, therefore, at this point, does not contest Petitioner’s definition for one of ordinary skill in the art. Petitioner’s proposed definition appears to be consistent with the disclosure of the ’947 patent, and we adopt it for purposes of this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that the prior art itself may “reflect[] an appropriate level” of ordinary skill in the art) (quoting Litton Indus. Prods., Inc. v. Solid State Sys.

“Having considered the record, we determine that no express claim construction is necessary for any claim terms for the purposes of rendering a decision to institute trial. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (holding that only claim terms in controversy need to be construed, and only to the extent necessary to resolve the controversy (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). At this stage, we find it unnecessary to resolve whether “electronic control unit” and “processing module” should be construed as mean plus function limitations under § 112(f), because it is possible to address the obviousness grounds presented whether or not these limitations are so construed, and even if the claims were indefinite in the manner Petitioner contends. See Intel Corp. v. Qualcomm Inc., 21 F.4th 801, 813 (Fed. Cir. 2021) (noting indefiniteness of a means-plus-function limitation does not always render it impossible to adjudicate a prior-art challenge).

Thus, we find that Petitioner has shown that it is more likely than not that claim 1 would have been unpatentable as obvious over ElMasry.” slip op. at 20

“partes review, “the Director may take into account whether, and reject the petition or request because, the same or substantially the same prior art or arguments previously were presented to the Office.” Our § 325(d) analysis employs a two-prong framework: (1) whether the arguments presented in the petition are the same or substantially the same as those previously presented to the Office; and (2) if so, whether the petitioner has demonstrated a material error by the Office in its prior consideration of those arguments.

Osseo Imaging, Inc., IPR2020-00659, Paper 10 at 19 (PTAB June 10, 2020)), Patent Owner essentially asks us to resolve multiple factual issues related to its contract dispute with Linq3 to justify denial of institution.

In particular, this proceeding challenges claims of a different patent than the patents at issue in PGR2020-00084 and IPR2023- 01235. Challenging claims of different patents significantly distinguishes the facts here from those in General Plastic, and we decline Patent Owner’s invitation to extend General Plastic in this regard.
