“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

“We disagree with Weber’s position, at least on the current record. Instead, we find that Provisur presents sufficient evidence that Young anticipates all elements of independent claims 1 and 14, including the disputed limitation requiring “automatic determination of the thickness of the fat cover.” In particular, Young’s imaging system 190 includes multiple cameras, including top plan camera 196, end view camera 197, and fat line camera 198, as well as controller 172 and real-time image processor 194. Ex. 1004, 17:34–59, 18:46–56, Figs. 2, 13. As described by Young, top plan camera 196 is primarily used to obtain “physical dimensions and characteristics” of the meat product, end view camera 197 is primarily used to determine the “height” of meat product and “to create a clear delineation along the top edge of the end” of the meat product, whereas fat line camera 198 is primarily used to determine the fat/lean separation line of the meat product. See id. at 17:59–18:39. Those disclosures by Young clearly contemplate determining specific dimensions of the meat product, and not simply identifying the fat/lean separation line, as Weber suggests. See Prelim. Resp. 19. To determine the “thickness” of the fat cover, Young’s imaging system has image processing routine 240, which “generates a fat/lean separation line and an edge line . . . representing the outer surface of the pork side proximate the fat/lean line” and uses those lines to calculate “the height, width, and length of the [meat product].” Ex. 1004, 23:12–25, 24:10–22. As part of routine 240, controller 172 uses that information to set the cutting profile of knife assembly 100 “so that the assembly follows a fixed distance from the separation line to provide the optimum fat cover for the loin.” Id. at 18:35–39 (emphasis added). Notably, according to Young, the “fixed distance” represents the “desired” thickness of fat that remains on the meat, after cutting, and “sufficiently keeps the loin from drying out, but doesn’t make the loin look too fat.” Id. at 20:60–66; see also id. at 10:39–42 (“Through control of the knife blade along several axes, assembly 100 preferably produces an optimum separation between loin and belly, with a desired fat covering left on the loin.” (emphasis added)). Young’s disclosure that image processing routine 240 determines a “fixed distance” from the loin/fat separation line at which to cut the meat product undoubtedly corresponds to the claimed “determination of the thickness of the fat cover . . . in a contactless manner.” See Ex. 1003 ¶¶ 104–112. Indeed, Young discloses specific dimensions for the desired optimum fat cover to remain on the meat—“a fixed distance (preferably 0.1 inch) from the fat/lean separation line 6.” Ex. 1004, 20:55–63.” slip op. at 8

RulingsInstitution decision- PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)InstitutedDecided for petitioner
“The Board has set forth certain factors (“the Fintiv factors”) that may be considered in determining whether to exercise its discretion to deny institution based on the advanced stage of a parallel proceeding: 1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits. Fintiv, IPR2020-00019, Paper 11, at 5–6. On June 21, 2022, the Director of the Office issued a Memorandum to clarify how the Board should apply certain Fintiv factors when determining whether to exercise its discretion to deny institution under § 314(a).4 The 4 Memorandum Re: Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (June 21, 2022), available at https://www.uspto.gov/sites/default/files/documents/ interim_proc_discretionary_denials_aia_parallel_district_court_litigation_memo_2 0220621_.pdf. (“Memo”). Memorandum explains that the Board should decline to exercise its discretion to deny institution where: (1) a petition presents compelling evidence of unpatentability; (2) a request for denial under Fintiv is based on a parallel ITC proceeding; or (3) a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition. Memo 2–3. Moreover, when analyzing Fintiv’s second factor, the Board will consider the published median time to trial in the district court in which the parallel litigation resides. Id. at 3. B. Analysis of the Relevant Fintiv Factors As explained further below, we find the Petition presents compelling evidence of unpatentability with respect to the challenges over the EMA reference, which precludes us from exercising our discretion to deny institution under Fintiv. Memo 4–5. Although that factor alone is sufficient to end our analysis, we further note that several other factors support declining to exercise our discretion, as well.” slip op. at 7

“Petitioner asserts: An ordinary artisan as of October 24, 2001 would have been a person having a Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Computer Engineering, or Computer Science, or an equivalent degree with at least two years of experience in electronic user interface systems and vehicle sensor systems or related technologies. Additional education may substitute for lesser work experience and vice-versa. (Ex.1003, ¶19.) Pet. 3 (citing Andrews Declaration). Patent Owner does not address the definition of the person of ordinary skill in the art, either to contest Petitioner’s proposal or to offer a different definition. See generally Prelim. Resp. For the purposes of this Institution Decision, we accept Petitioner’s unopposed, proposed definition of the person of ordinary skill in the art (or ordinarily skilled artisan), which appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’709 patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“one of ordinary skill in the art, and therefore no claim construction is necessary at this time.” Pet. 5. Patent Owner argues that Petitioner appears to provide some interpretation of the claims in its challenges and states that Petitioner’s assertion that the claims carry their plain and ordinary meaning is “flawed,” but does not expressly assert that any claim language requires express construction by the Board. See Prelim. Resp. 9–10, and generally. At this stage of the proceeding, we do not find it necessary to construe any claim language. The language of the claims appears to be readily understandable on its face. If any claim language is in dispute at trial, we encourage the parties to further develop the record thereon.

“For purposes of this Decision, we generally accept Petitioner’s proposed definition of the person of ordinary skill in the art (or ordinarily skilled artisan), which appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosures of the ’548 patent; however, we also agree with Patent Owner that such a definition should be flexible enough to include a person with a lesser academic degree and having experience working in the field, such as an engineer with clinical experience in ophthalmic surgery, as well as a medical doctor, such as an ophthalmic surgeon with experience working with medical optics and lasers. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (noting that the appropriate level of ordinary skill in the art may be reflected in “the prior art itself”) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). Such an expanded definition of the person of ordinary skill in the art, including aspects of both parties’ definitions, is appropriate based on our review of the record, which demonstrates individuals having a broad array of scientific degrees that collaborate as a team. We note, however, that our decision to institute trial in this proceeding would not change were we to adopt Patent Owner’s proposed definition.” slip op. at 8

“and evidence supporting such grounds,” including “the prior art relied upon and evidence that it qualifies as such.” Hulu, Paper 29 at 13 (citing 35 U.S.C. § 312(a)). The Petition identifies the grounds for institution and the evidence supporting such grounds, and presents evidence that Weikert qualifies as prior art under 35 U.S.C. § 102(b). Pet. 5–6, 28–29. For example, Petitioner and Dr. Lubatschowski assert that CATARACT AND REFRACTIVE SURGERY “is a quarterly review series comprising chapters written by well-known specialists,” and that Weikert was included in the 2005 edition of CATARACT AND REFRACTIVE SURGERY as Chapter 14: Refractive Keratotomy: Does it Have a Future Role in Refractive Surgery? Ex. 1001 ¶ 73. Although minimal, given the type of document involved, and in the absence of any reason to question Petitioner’s and Dr. Lubatschowski’s assertions, Petitioner’s evidence is sufficient to present a reasonable likelihood that Weikert is prior art to the ’548 patent under 35 U.S.C. § 102(b).” slip op. at 11
