“E. Credibility of Dr. Doolittle Patent Owner argues that we should give no weight to Dr. Doolittle’s testimony because, “[o]n cross examination, Prof. Doolittle repeatedly contradicted himself, dodged questions, and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions.” PO Resp. 25. Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. 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. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. 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. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions. Ex. 2025, 22:10–23:15, 25:9–26:14, 30:14–22, 40:3-9, 58:12–59:1, 60:18–61:13, 65:1–10, 83:15–84:16, 92:15–95:20, 96:18–99:9, 102:22–106:16, 135:3–136:22. An answer is not “non-responsive” simply because it does not conform to the conclusion you want or undermines the logic underlying your questioning. Dr. Doolittle explained his answers and addressed the issues Patent Owner asked about. Accordingly, we decline Patent Owner’s invitation to give Dr. Doolittle’s testimony no weight.

- Skill levelOther
“B. Level of Ordinary Skill in the Art We consider the asserted ground of unpatentability in view of the understanding of a person of ordinary skill in the art (“POSITA” or “POSA”). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d Relying on the declaration testimony of its expert, Dr. Doolittle, Petitioner contends that an ordinarily skilled artisan for the ’678 patent “would have had an undergraduate degree (i.e., B.S., B.S.E. or the equivalent) in electrical engineering, materials science, physics, or a similar discipline” and “would also have one to two years of experience in the field of LED packaging design.” Pet. 5–6. Petitioner additionally contends that “[m]ore education could substitute for experience, and vice versa.” Id. Petitioner further contends that “[t]his person would have been capable of understanding and applying the teachings of the ’678 patent and the prior-art references discussed herein,” and “[m]oreover, the prior art reflects the level of skill at the time of the claimed invention.” Id. (citing Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); Ex. 1102 ¶¶ 38–42). Patent Owner states that “solely for the purposes of this proceeding, Patent Owner and its technical expert employ the same level of skill in the art as Petitioners.” PO Resp. 24–25.

“To determine how a person skill in the art would determine if a shrink label is “recyclable” as recited in the independent claims, we look to how the Specification of the ’422 Patent describes or defines recyclable shrink labels. For example, the ’422 Patent states that PET shrink films are generally considered recyclable if no inks are retained on the film after a caustic wash cycle typically used in PET reclaiming processes. Ex. 1001, 6:61–65. The ’422 Patent further states that labels are fully recyclable if the polymers used are clear, preferably clear PET, and the labels include inks that can be washed off in a “typical PET recycling wash (caustic wash).” Id. at 11:44– 49; see also id. at 11:49–54 (describing embodiments in which the labels are free or substantially free of inks that cannot be washed off in a caustic wash or where the labels are free or substantially free of color plastics that cannot be recycled). The ’422 Patent further discusses “industry standards” for determining whether various embodiments of shrink labels are recyclable. See, e.g., id. at 11:29–53. For example, the Specification states that the “Association for Plastic Recyclers (APR) Critical Guidance Protocol for Clear PET Articles with Labels and Closures (PET-CG-02)” (Ex. 1005) can certify that a film is fully recyclable with a container or bottle. Id. at 11:34– 38. Additionally, the Specification states that labels “are recyclable according to the Evaluation of the Near Infrared (NIR) Sorting Potential of a Whole Plastic Article (SORT-B-01)” (Ex. 1010) and/or the “Evaluation of Sorting Potential for Plastic Articles Utilizing Metal, Metalized, or Metallic Printed Components (SORT-B-03)” (Ex. 1011). Ex. 1001, 11:39–44. The ’422 Patent further states that embodiments of the labels “are fully recyclable. For example, the labels may include inks that can be washed off in a typical PET recycling wash (caustic wash) and the polymers” are preferably clear PET. Id. at 11:44–48. The ’422 Patent thus provides various descriptions or standards to determine the recyclability of shrink labels. For the purposes of addressing the anticipation and obviousness grounds, we determine that any of these standards can be used to determine if a shrink label is “recyclable.” We note that our construction is preliminary and is based on the present record. We invite the parties to further the address the construction of “wherein the recyclable shrink label is recyclable with a PET container” during trial.” slip op. at 12

“Both parties rely on expert testimony for their respective positions relating to the number of years of experience needed to attain ordinary skill, but neither expert cites supporting evidence for their testimony. See Ex. 1002 ¶ 33; Ex. 2002 ¶ 15. Our decision is the same regardless of whether the length of experience is two years or three. We find Patent Owner’s proposed “wireless communications” is more consistent with the ’958 patent than Petitioner’s proposed “telecommunication,” which encompasses a variety of technologies including, e.g., landline and wireless telephones, cable, and satellite. See Ex. 1001, 1:11–62 (describing the invention in terms of wireless communications). Accordingly, we adopt a modified version of Petitioner’s proffered level of ordinary skill in the art, substituting “wireless communications” for “telecommunication.” Neither party, moreover, indicates the overall result would change based on a different definition.” slip op. at 18
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

“(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17. In its Sur-reply, Petitioner contends that limitation 7h’s requirement of transmitting the group identifier was previously “set out in Patent Owner’s prior papers,” but does not refer to any specific papers or exhibits. Pet. Surreply 11–12. We decline to search for and piece together Petitioner’s arguments and evidence to develop a persuasive theory of unpatentability. See 37 C.F.R. section 42.6(a)(3). Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag.

“priority benefit of the ’720 provisional application (at top center). See Ex. 1001, code (60) (listing “provisional application No. 5,995,873, filed on Oct. 2, 2006”). However, simply to claim the priority benefit of an earlier application is not necessarily to receive it. See In re NTP, Inc., 654 F.3d 1268, 1276 (Fed. Cir. 2011) (holding that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority.… Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120.”). As the diagram shows (and as we have verified), the ’529 application was a continuation-in-part of the preceding ’329 application. See Ex. 1001, code (63). However, the ’529 application was abandoned on February 10, 2016 (See Ex. 1052), and the succeeding application, U.S. Patent Application Ser. No. 15,474,875 (the “’875 application”) which is listed in the ’943 patent as being a continuation-in-part of the ’529 application, was not filed until March 30, 2017. See Ex. 1001, code (63) (stating that “said application No. 15/474,875 is a continuation-in-part of application No. 12/508,529”). Put simply, the ’875 application was not filed until over a year after the ’529 application was abandoned. As 35 U.S.C. § 120 states, in relevant part: An application for patent for an invention disclosed in the manner provided by section 112(a) (other than the requirement to disclose the best mode) in an application previously filed in the United States, or as provided by section 363 or 385, which names an inventor or joint inventor in the previously filed application shall have the same effect, as to such invention, as though filed on the date of the prior application, if filed before the patenting or abandonment of or termination of proceedings on the first application or on an application similarly entitled to the benefit of the filing date of the first application and if it contains or is amended to contain a specific reference to the earlier filed application. (emphasis added). In other words, if there is a “break in the chain” of priority caused by the abandonment or termination of an application claiming priority prior to filing of a subsequent application, the subsequent application loses the priority benefit of the abandoned or terminated application, as well as the priority benefit of all applications that antedate that abandoned or terminated application. Such is the case presently before us. Based on the current record, we are persuaded that the abandonment of the ’529 application prior to filing of the continuation-in-part ’875 application broke the priority chain leading to the ’720 provisional application, and the ’943 patent cannot, therefore, claim the priority benefit of the ’720 provisional application’s October 2, 2006 filing date. Consequently, the earliest date of which the ’943 patent could possibly claim the priority benefit is that of U.S. Patent Provisional Application Ser. No. 61/403,680 (the “’680 provisional application”) (located at the top of the left branch of the “family tree” depicted above), which has a filing date of September 20, 2010. See Ex. 1001, code (60). Burnett (i.e., the ’329 application) was filed on October 2, 2007 and thus antedates the ’680 provisional application. Consequently, Patent Owner’s argument fails based on the current record, and Burnett is prior art to the ’943 patent.” slip op. at 55

“For these reasons, we do not find persuasive the testimony of Patent Owner’s expert, Dr. Dobs, that: By describing adjustments of dosing protocols to achieve an A4 reduction from baseline, and describing this use of tildacerfont as just one embodiment of the claimed use of the entire well-known, well-characterized, and discrete class, the specification reasonably conveyed to a POSA that the invention extended to the particularly claimed use of the entire recited class. Ex. 2014 ¶ 82. On the contrary, far from being a “well-known, well-characterized, and discrete class” the prior art teaches a heterogeneous assembly of different classes of small molecule CRF1 receptor antagonists (Type I, Type II, and “atypical”) displaying a very considerable variety of structures, both in terms of the core pharmacophore (e.g., monocyclic, bicyclic, tricyclic, phenolic, cyclohexyl amide, etc.) as well as in the various side groups. Moreover, the challenged claims recite only “a CRF1 receptor antagonist or a pharmaceutically acceptable salt thereof,” the scope of which also encompasses the much larger (and, according to Williams) much more effective large-molecule (peptide) CRF1 receptor antagonists, about which the Specification is entirely silent. See Ex. 1029, Abstr., 1065. Furthermore, despite Dr. Dobs’ testimony that “[t]he [prior art] references explain the typical CRF1 antagonist consists of a core nitrogen heterocycle with an aryl substituent adjacent to the core nitrogen atom and a branched alkyl group attached at the opposite end of the core,” Dr. Dobs also acknowledged that the “atypical CRF1 receptors depicted in Figures 11 and 12 of Williams had different structures, and lacked the nitrogen heterocyclic core.” Ex. 1042, 127:9–14, 130:13–131:16; see also Ex. 2014 ¶ 83.
