    • BurdenDecided for petitioner

      “Patent Owner, however, has not identified any language in the Petition that explicitly incorporates by reference Dr. Sundaresan’s testimony. See generally PO Resp.; PO Sur-Reply. Nevertheless, to the extent that the Petition purportedly incorporates by reference Dr. Sundaresan’s testimony, we do not find such incorporation sufficiently extensive to merit disregarding the testimony. Typically, an incorporation by reference is deemed improper in instances in which large portions of a declaration are incorporated—particularly where the incorporation serves to circumvent a word-count limit. See, e.g., Cisco Systems, Inc. v. C-Cation Techs., LLC, IPR2014-00454, Paper 12 at 10 (PTAB Aug. 29, 2014) (informative). In this case, however, Dr. Sundaresan’s testimony describing the level of ordinary skill in the art is short. Ex. 1003 ¶ 8. The amount of testimony is not extensive and, thus, its purported incorporation into the Petition presents little or no imposition on Patent Owner or the Board.” slip op. at 12

      “In reply, Petitioner argues that “under any reasonable read of the Sundaresan Declaration, Dr. Sundaresan implied agreement with the POSITA definition based on its inclusion in a signed declaration.” Pet. Reply 15. We agree with Petitioner. Although Dr. Sundaresan does not state explicitly that the proposed definition of the ordinary skill in the art is his opinion, we are persuaded that the manner in which the definition is set forth in his declaration indicates that he agrees with the definition. Patent Owner attempts to make much of Dr. Sundaresan’s statement that he had been informed of the qualifications of a person of ordinary skill in the art. See PO Resp. 41–43. Dr. Sundaresan’s testimony, however, set forth this understanding of the requisite level of skill in the art (Ex. 1003 9 Dr. Sundaresan has a doctoral degree in electrical and computer engineering and has extensive experience in wireless communications. Ex. 1003 ¶¶ 75–78. Dr. Sundaresan also has experience with navigation and geolocation systems such as development of wireless tracking systems, as evidenced by his experience in companies such as NavigateIO Inc. Id. at ¶¶ 77–78. Patent Owner does not argue that Dr. Sundaresan fails to meet requirements for the level of qualifications of one of ordinary skill in the art under its proposed qualifications, which we adopt here. See generally PO Resp.; PO Sur-reply. Based on a review of his qualifications, we determine that Dr. Sundaresan qualifies as a person of ordinary skill at the time of the invention. ¶ 8). In his supplemental declaration, Dr. Sundaresan testifies: I agreed with this POSITA definition when preparing the Declaration, and I continue to hold the opinion that the POSITA definition is both correct and appropriate based on the disclosures of the ’358 patent and the prior art analyzed in the Declaration. Ex. 1055 ¶ 17. Dr. Sundaresan further testifies that “[i]f I did not agree with the POSITA definition, then it would not have been included [] in paragraph 8 of the Declaration.” Id. ¶ 18. Dr. Sundaresan’s inclusion of the definition of the level of ordinary skill in his original declaration indicates that he agrees with the definition, as confirmed by his cited subsequent testimony. We note that, even with Patent Owner’s arguments, the record is clear that Patent Owner was on notice of Petitioner’s proposed definition of the level of ordinary skill at the time of the Petition. Pet. 6; cf. Corephotonics, Ltd. v. Apple Inc., 84 F.4th 990, 1006 (Fed.

Patent Owner specifically argues that 11 Patent Owner also argues that Petitioner does not establish that Haddad138 anticipates claim 2. Prelim. Resp. 5–7. We do not address the anticipation challenge at this time. “Petitioner does not offer any showing on any motivation to modify Figure 9 of Haddad138 to change the configuration from a FSI to BSI architecture.” Id. at 8. On this record, Patent Owner’s argument does not undermine Petitioner’s persuasive showing. As Petitioner argues (Pet. 29), Haddad138 teaches that its “present disclosure” (which would include the Figure 9 disclosure) can be adapted for a front side illumination (FSI) or back side illumination (BSI) configuration. Ex. 1012 ¶ 48. The express teaching of Haddad138 provides motivation to modify Figure 9 of Haddad138. Patent Owner also argues that Petitioner “offers no showing that a POSITA would be able to modify the embodiment of Figure 9 to be back side illuminated with a reasonable expectation of success.” Prelim. Resp. 9. Patent Owner’s argument again does not undermine Petitioner’s persuasive showing. Petitioner cites Haddad138 expressly teaching a FSI or BSI configuration. Pet. 29 (citing Ex. 1012 ¶ 48).

Here, however, as Patent Owner observes (Prelim. Resp. 10), 8 Patent Owner does not present arguments or evidence of secondary considerations in its Preliminary Response. Therefore, secondary considerations do not constitute part of our analysis herein. Petitioner has provided no assessment as to the level of ordinary skill to be considered in evaluating the grounds of obviousness that are advanced by Petitioner.

      “We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard.

      “Although Petitioner puts forth constructions for terms in the claims of the ’795 patent, Patent Owner argues that we need not expressly construe any terms to resolve the controversy between the parties. (See Pet. 14–19; see PO Resp. 12.) Except as indicated below, we agree that express construction of the claim terms is not required because the parties do not materially dispute the meanings of the terms. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Limitation (c) of claim 1 recites “syrup formulation” once and then “syrup” by itself twice. The parties agree that two recitations of “syrup” by itself mean and are synonymous with “syrup formulation.” (See Tr. 15:16– 19 (counsel for Petitioner: “[T]he term, syrup, by itself, means the formulation. And for that reason, we--it’s our position that it’s the syrup formulation that has the specific viscosity requirements as well as the other features that we discussed.”); 31:17–20 (counsel for Patent Owner: “But those wherein clauses, what it’s referring to, the syrup formulation and the syrup -- it was all to a complete to a final formulation, right, it’s not just the agave syrup. Everybody here recognizes and understands that from that perspective.”).) Thus, the parties agree that the “viscosity of less than 1500 centipoise at about 22 degrees” limits the final “pharmaceutical syrup formulation for oral administration,” not the “agave syrup” limitation in limitation (b) of claim 1.” slip op. at 7

      “Patent Owner argues further that Dr. Crowley testifies that, “[g]enerally, suspensions having a viscosity in the range of 20 to 150 cP are considered readily pourable,” but that this range is well below the viscosity range of 200–900 cP taught in WO133 and the preferred viscosity range of 1000–3000 cP taught in the ’4666 patent. (See PO Resp. 45 (quoting Ex. 1003 ¶ 59).) Dr. Crowley testifies that “increasing the viscosity of a suspension formulation has been shown to impair the dissolution characteristics of immediate release acetaminophen” and that, “[w]ith respect to suspensions for oral administration, having a higher viscosity is generally not desirable.” (Ex. 1003 ¶ 59.) According to Patent Owner, this is a “teaching away” because Petitioner’s own expert testimony demonstrates a motivation not to combine the acetaminophen formulation of FR458- Example 1 with the 1000-3000 cP range of the ’4666 patent and the 200-900 cP range of WO133 since by his own admission doing so would yield bad results (i.e., impairing the dissolution characteristics of the acetaminophen) and generally undesirable higher viscosity. (PO Resp. 46 (citing Berkland Decl., Ex. 2009 ¶ 148).) Dr. Crowley’s cited testimony, however, is about general characteristics of suspensions for oral administration, whereas the WO133 refers specifically to sweetened analgesic formulations. (See Ex. 1006, 8:1– 3 (“The viscosity of the acetaminophen composition generally ranges from about 200–900 centipoise, preferably from about 300–700 centipoise.”); see Pet. Reply 8–9.) As Petitioner notes, Dr. Crowley also testifies that the viscosity of 29 commercially available, pediatric liquid oral antibiotic formulations were measured and determined to range from 20 to 1,780 cP” and that “[t]he viscosity of Children’s Tylenol has been reported to be less than 1,000 centipoise at shear rates between 0.05 and 0.2 reciprocal seconds.” (Ex. 1005 ¶ 58.) Thus, we are not persuaded that Dr. Crowley’s testimony contradicts the teachings regarding viscosity of analgesic formulations in the cited prior art.” slip op. at 23

    • Expert testimonyPatent owner expert creditedDecided for patent owner

      “In particular, we agree with Patent Owner that “[n]ot only does Cantor not teach contacting a ‘tissue sample’ with beads, but Cantor comes nowhere close to suggesting that its beads could be contacted with a tissue sample to identify spatial location.” Prelim. Resp. 50. Here, we are persuaded by the testimony of Dr. Cantor, sole inventor of Cantor (Ex. 2002 ¶ 29), that Cantor’s nucleic acid samples are made in bulk from the extraction of nucleic acids from biological material and mixed together “to create the sample nucleic acid prior to mixing that with the solid phase nucleic acids to capture molecule(s) from the sample nucleic acid.” Id. at ¶ 17. More specifically, “nucleic acids are extracted from the different types of cells within a tissue sample without preserving their spatial distribution.” Id. at ¶ 19. Thus, these types of “bulk-analysis techniques provide no information about spatial location of biological molecules in tissue samples.” Id. at ¶ 17. While we recognize that Cantor discloses “providing the beads according to an (X,Y) array” (Pet. 39, citing to Dr. Puglisi, Ex. 1100 ¶¶ 65– 66), this disclosure makes no mention of using this array to map where the nucleic acids of Cantor came from relative to the original sample, let alone when that original sample is a tissue. See e.g. Ex. 1031, 17. The only mentions of “tissue” made in Cantor are in reference to where the sample may be obtained, for example, “[t]he biological sample can be in any form, including without limitation a solid material such as a tissue.” Id. at 6. Cantor provides no teaching, however, regarding how to use a tissue sample with the probes and methods described in Cantor to identify where the target nucleic acids of Cantor were spatially located within the tissue sample itself. Incidental to the parties’ dispute is whether Petitioner’s reliance on and characterization of Cantor’s use of the terms “sample” and “nucleic acid sample” as equivalent in meaning to “tissue sample” recited in the challenged claims is persuasive. Pet. 21 (citing Ex. 1031, 6). Here, we note that Cantor discloses that “[s]ample nucleic acid may be derived from one or more samples or sources.” Ex. 1031, 5; Ex. 2002 ¶¶ 35, 149. Cantor refers to “sample” as the thing that contains the sample nucleic acid. Ex. 1031, 5. For example, Cantor discloses that “[a] sample may be collected from an organism.” Ex. 1031, 6; Ex. 2002 ¶ 42. When a “sample” comes from a living (or formerly living) source, Cantor refers to that sample as a “biological sample,” which can “be in any form, including without limitation a solid material such as a tissue, cells, a cell pellet, a cell extract, or a biopsy, or a biological fluid . . . .” Id. Those samples, however, are further processed in bulk to obtain the nucleic acid sample. For example, Cantor discloses that the “sample nucleic acid may be a result of nucleic acid purification or isolation and/or amplification of nucleic acid molecules from the sample.” Ex. 1031, 7; see also id. at 54 (The “sample nucleic acid” is derived from a sample or source “by any means commonly known in the art, including but not limited to cell lysis procedures using chemical, physical or electrolytic lysis methods.”); Ex. 2002 ¶ 39. In view of the above, we are not persuaded by Petitioner’s attempts to characterize Cantor’s “nucleic acid sample” as synonymous to “tissue sample” recited in the challenged claims. Rather, we agree with Dr. Cantor that “[a] tissue is simply the source of the sample nucleic acid used in [Cantor’s] methods”—it is not the sample nucleic acid itself. Ex. 2002 ¶¶ 36, 150. Petitioner does not direct us to any persuasive evidence to the contrary.” slip op. at 21

Here, Fintiv factors one and five are neutral, factors two and three favor discretionary denial, factor four strongly weighs against discretionary denial, and favor six weighs against discretionary denial. The integrity of the system will benefit from institution because of the strong merits the Petition presents (factor six), and the ITC Investigation will not resolve these merits (factor four). This outweighs any potential inefficiency as indicated by factors two and three.

      “After considering the record as a whole, we determine that Petitioner has adequately demonstrated that the Office erred in a manner material to the patentability of challenged claims. As we explain in Section III(G), infra, Petitioner’s challenges to the ’227 patent appear strong based on the current record, and Patent Owner’s present arguments to the contrary are weak. Given the strength of Petitioner’s challenges on the present record, this is not a situation where we would say that “reasonable minds can disagree regarding the purported treatment of the art,” and we therefore determine that the Examiner erred by not considering the art in substantially the combination Petitioner proposes. Where Patent Owner states that “evidence that the Examiner did not consider these references in combination” is lacking (PO Sur-Reply 5), we disagree. If the Examiner considered these references in combination, the Examiner would have, given the apparent strength of Petitioner’s position on the merits on this record, issued a rejection. The lack of a rejection based on the combination proposed in the Petition provides some evidence that the Examiner did not consider these references in combination (because the lack of such a rejection raises the likelihood that the Examiner did not make such a consideration). 3. Conclusion Because Petitioner adequately made a showing of material error, we decline to exercise discretion not to institute inter partes review under 35 U.S.C. § 325(d).
