    “In response, we conclude that the most natural reading of limitation [l] results from examination of the entire limitation: “locating encryption information that identifies encrypted portions of frames of video within the requested portions of the selected stream of protected video.” Ex. 1001, 27:54–57. The “within” most naturally connotes where the encrypted portions of frames of video occur, as opposed to determining where the encryption information may be located. Patent Owner’s interpretation is not wrong, i.e., the limitation could be read as Patent Owner suggests, leading to a narrower construction, but we are not persuaded that the construction of limitation [l] must be so limited, on the basis of the words themselves. We continue to reject Patent Owner’s interpretation that limitation [l] requires locating encryption information within the requested portions of the selected stream of protected video. See Inst. Dec. 27–30; 1st Final Dec. 8. Although it is apparent that encryption information can be found within the requested portions, we are not persuaded that the claim language or ’588 Patent implicitly or explicitly requires such a relationship. Likewise, although embodiments disclosed in the Specification of the ’588 Patent are consistent with Patent Owner’s more restrictive construction, the Specification also is consistent with the more grammatically correct construction as well. Thus, we construe limitation [l] as requiring that the encrypted portions of frames of video be within the requested portions of the selected stream of protected video, but we do not construe limitation [l] as requiring that the encryption information be within the requested portions of the selected stream of protected video.” slip op. at 15

Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28.

Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues.

    “We find unpersuasive Mr. Pollock’s testimony that we limit the level of ordinary skill to “refrigerated display cases” because defining the level of skill as an engineer with experience “working with refrigerated display cases” does not relate to the technology disclosed and claimed in the ’181 patent, which is controlling condensation and conserving energy. E.g., Ex. 1001, 2:17–21 (“The invention is proactive in preventing condensation temperature at frame and door surfaces is reached. Power is then cycled off at a set point above dew point to save energy.” (emphases added)). An electrical engineer with a bachelor’s degree and 2 years of experience focused on lighting systems for refrigerated display cases would have “experience working with refrigerated display cases,” and thus meet Patent Owner’s proposed level of skill. Such a person, however, would not be experienced in controlling condensation, dew point sensor positioning, and condensation algorithm design, which is the focus of the disclosed and claimed invention, and which Mr. Pollock states “materially affect performance, energy use, and reliability” in controlling condensation in a refrigerated display case. Ex. 2014 ¶ 11. We also note that Mr. Pollock’s qualifications are a “B.S. in Mechanical Engineering, cum laude, from Drexel University (1998), with focus on thermal and mechanical systems, thermodynamics, and HVAC&R (Heating, Ventilation, Air Conditioning & Refrigeration).” Ex. 2014 ¶ 3. Accordingly, based on the prior art, the sophistication of the disclosed technology in the ’181 patent, finding Mr. Pollock’s testimony on this issue too general, and crediting Dr. Henze’s testimony with substantial probative weight, we adopt Petitioner’s definition of the level of ordinary skill. We modify it to state that more academic training will offset less experience, and more experience will offset less academic training, as did Dr. Henze (Ex. 1003 ¶ 31).

We determine, based on the record before us, that Dr. Henze’s Declaration testimony meets these requirements. He provides, as required, the facts and data to support his testimony.

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Petitioner asserts that [t]he person of ordinary skill in the art (POSA) would have been an M.D. and/or Pharm. D who would have completed training in medical oncology, particularly in the field of gastrointestinal (GI) cancers, or a Ph.D. in clinical pharmacology, pharmaceutical sciences, pharmaceutics, and/or drug delivery, also particularly in the field of GI cancers, or their equivalents, along with at least 1-2 years of post-doctoral experience. Pet. 26 (citing Ex. 1002 ¶¶ 44–46). Patent Owner states that, for purposes of this proceeding, it does not dispute Petitioner’s proposed definition of a POSA. PO Resp. 8. Based on the entirety of the trial record, we adopt Petitioner’s proposed definition of a POSA’s skill level because it is consistent with the skill level reflected in the disclosures of the ’552 patent and prior art.

    “We decline to discount Dr. Oberstein’s opinion based on the alleged conflict of interest and bias. Dr. Oberstein testified that the consulting fees he receives from Patent Owner reflect a small fraction of his income. Ex. 1210, 402:21–403:9. We also agree with Patent Owner that an oncologist prescribing an FDA-approved regimen does not evince bias. See Sur-reply 23; see also Ex. 1206, 49 (showing NALIRIFOX is a category 1, NCCN-preferred first-line therapy for metastatic pancreatic cancer), 69 (explaining category 1 is based upon high-level evidence). Petitioner also contends that Dr. Oberstein “offers conclusory opinions,” “fails to properly apply the law, continues to look at each reference in isolation, refuses to acknowledge logical suggestions in the art, and imports new limitations into the claims.” Reply 3–4.

We, however, rejected the notion that the claims “would require some particular degree of clinical efficacy” because “the level of clinical efficacy is not a claim limitation.” Id.” slip op. at 12

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Not reached

    “The parties, however, disagree over whether each recited dose must be the starting dose. Petitioner argues that “claim 1 requires that the method of treatment is a first-line therapy, but does not require that the claimed doses be used as a starting dose.” Paper 51, 1. In contrast, Patent Owner argues that “[t]he specification describes that the recited dose of each drug is a ‘starting’ or ‘initial’ dose.” Paper 50, 2 (citing Ex. 1001, 13:38–45, 30:5–7). For purposes of this Decision, we do not need to resolve this dispute. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (stating that claim terms need only be construed to the extent necessary to resolve the controversy). As explained below, we agree with Petitioner that, even if claim 1 recites the starting dose for each drug, Petitioner has shown, by a preponderance of the evidence, that the prior art teaches each dose and a POSA would have had a reason to start with the recited doses. See infra Section II.G.3; Paper 51, 3 n.2. Because we find that the prior art teaches or suggests the claimed subject matter even under Patent Owner’s proposed narrower claim interpretation, we need not further construe the disputed claim language.” slip op. at 16

  • ExcludeMotion to exclude, deniedDenied

    “In this case, Patent Owner’s expert “Dr. Zhou signed the second declaration, stood behind its contents, and was available for cross-examination.” Paper 35, 4. Petitioner does not dispute this statement. Paper 39, 1. Petitioner does not identify any specific undue prejudice caused by Exhibit 2008. For example, Petitioner argues that “the failure to impress upon a witness that a statement is under oath goes to the heart of its reliability as evidence” and that “as the Board has recognized, hearsay is inherently unreliable” without specifying what statement in Exhibit 2008 lacks reliability. Paper 39, 4. Because Petitioner does not provide specific evidence of undue prejudice, we find Petitioner has suffered no such undue prejudice in this case. See Liquidia, 2021 WL 4860773 at *25. We therefore deny Petitioner’s Motion to Exclude on the basis of lack of authenticity. With regard to the assertion that Exhibit 2008 is hearsay, Petitioner objects to the exhibit because the testimony is based “on other informal and unpublished documents that are hearsay under FRE 802.” Paper 29, 1. Petitioner does not specify what such “informal and unpublished documents” are. See id. Federal Rule of Evidence 703 expressly states, “[a]n expert may base an opinion on fact or data in the case that the expert has been made aware of or personally observed.” The facts or data “need not be deny Petitioner’s Motion to Exclude on the basis of hearsay.” slip op. at 50

  • Disclosure Requirements (§112) › Written description (Ariad)Written description adequateNot shown unpatentable

    “Petitioner’s argument is unpersuasive. Paragraph 59 of the ’503 application describes formula 8-1 but does not support Petitioner’s argument that other unknown formulas may be included in the recited modified heavy chains. Ex. 2003 ¶ 59. Petitioner’s hypothesis that the recited heavy chains may (or may not) encompass unknown formulas is also inapposite to the written description inquiry before us — that is, whether the inventor was in possession of the subject matter recited in claims 14–16 based on the disclosure including formulas 8-1, 8-2, and 8-3. See PowerOasis, 522 F.3d at 1306.” slip op. at 14

  • Disclosure Requirements (§112) › Enablement (Wands, Amgen full scope)EnabledNot shown unpatentable

    “These arguments in the Sur-Reply are unpersuasive to show a lack of enablement first and foremost because the arguments do not specifically provide evidence showing that any purported experimentation is undue. See Sur-Reply 2–8 (asserting, but without providing evidence under any specific Wands factors, that the examples and guidance in the specification do not extend to the broad scope of all antibodies); see Wands, 858 F.2d at 737. We again emphasize that the analysis of undue experimentation does not necessarily require every Wands factor to be explicitly addressed but the analysis must be based on “weighing many factual considerations” depending on the nature of the invention and underlying art. Cephalon, Inc. v. Watson Pharms., Inc., 707 F.3d 1330, 1336 (Fed. Cir. 2013). The assertion that the claim scope is broad alone does not suffice to show a lack of enablement based on the record before us. Moreover, as we note supra, Petitioner’s claim scope argument is based on the false premise that the scope of claims 14–16 is as broad as the claim term “antibody” without taking into account all other claim elements. For example, Petitioner does not disagree with Patent Owner’s statement that “[t]he ’675 Patent’s specification discloses the structural modification site, the chemistry used to modify that residue, and working examples demonstrating the modification” (Reply 2), but asserts only that “[t]he disclosure of SSFI that only binds to IgG1 Fc domains (SEQ ID NO:1) is . . . . inconsistent with the expansive scope of the claims.” Sur-Reply 5. Petitioner’s argument that the claims encompass proteins that lack a lysine reside at a 248 position improperly excludes from the claim language the “lysine residue at 248 position . . . [as] determined by the EU numbering system” that claims 14–16 require. As Dr. Zhou testifies, “each proposed lysine residue at position 248 (EU numbering) is covalently modified with a specific attachment with a terminal bio-orthogonal click-chemistry functional group. The specification describes targeted transfer of a chemical functional group to lysine 248” and when claims 14–16 are considered in their entirety, which includes all claim elements, “[a] POSA would understand the claim itself to limit the modified antibodies to those with lysine at position 248.” Ex. 2004 ¶ 48; Ex. 2008 ¶ 47. We also note that Patent Owner states “a POSA would understand that the phrase ‘one or more modified heavy chain’ encompasses antibodies within typical DAR distributions (i.e., fractional numbers) rather than requiring a distinct process for producing antibodies bearing modified heavy chains in exact integers.” Reply 2–3. Moreover, Patent Owner states that PepTalk Presentation demonstrates that “a POSA would understand antibody conjugation products to exist as mixtures rather than discrete whole number species” because PepTalk Presentation “presents DAR values as non-integer measurements, i.e. DARs of 1.8 and 1.9 reflecting such distributions.” Id. at 3 (citing Ex. 1007, 28). According to Patent Owner, “preparations having an average DAR of approximately 1.8 (commonly referred to in practice as ‘DAR2’) may reflect typical reaction distributions in which some antibodies contain two modified heavy chains while others contain fewer.” Id. at 3 (citing Ex. 2008 ¶ 46). Petitioner does not rebut these statements. See Sur-Reply 2–8. Based on the foregoing, the evidence before us does not show any” slip op. at 27

Petitioner does not explain how filling in a gap between the isolator 100 and a substrate necessarily results in “each of the plurality of optical isolators [being] disposed substantially in parallel relative to each other,” as recited in claim 1. The cited portion in paragraph 43 references Figures 5 and 6, which depict Embodiment 1 of Wang and are reproduced below. Figures 5 and 6 of Wang depict isolators 100, base 311, and baffles 312. Although paragraph 44 of Wang states that “[t]he substrate includes a base 311, and baffles 312 and isolators 100 sequentially disposed on the base 311,” Petitioner does not sufficiently persuade us how Wang’s disclosure “sequentially disposed” isolators necessarily discloses that the isolators are “disposed substantially in parallel relative to each other” as recited in independent claim 1. Ex. 1006 ¶ 44. Although the cited portion in Figure 6 of Wang apparently shows a possibly parallel arrangement of Petitioner cites to Dr. Kirk’s Declaration, but Dr. Kirk does not opine on why cited portions of Wang necessarily disclose or depict the claimed “disposed substantially in parallel relative to each other” requirement. Ex. 1003 ¶¶ 73, 74; Ex. 1006 ¶¶ 41, 43, Figs. 6, 8, 10. At best, Dr. Kirk testifies that “a POSITA would have understood that Wang anticipates Claim 1.” Ex. 1003 ¶ 75.
