    “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

    “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. See supra III.B.4 and IV.B. Further, we are not persuaded that Lee’s transmitting by broadcast is” slip op. at 26

    “Independent claims 1 and 19 recite a guide RNA or crRNA molecule having “gRNA functionality comprising associating with a Cas protein and targeting the gRNA:Cas protein complex to the target sequence.” Ex. 1001, 257:42–44, 259:5–7. This claim language makes clear that the recited “gRNA functionality” requires a molecule that can: (1) associate with a Cas protein, and (2) target that complex to a target sequence in a polynucleotide. To the extent Petitioner suggests that a gRNA “need only bind to the Cas protein” to have “gRNA functionality,” we disagree because the claims additionally recite the above-quoted targeting functionality. See Reply 16 (emphasis added). At the same time, we agree with Petitioner that “a gRNA need not cleave the target DNA” to have the claimed “gRNA functionality.” Reply 16. The Specification defines “gRNA functionality” as “one or more functions of naturally occurring guide RNA, such as associating with a Cas protein, or a function performed by the guide RNA in association with a Cas protein” and lists various gRNA functions, e.g., “associating,” “targeting,” “binding,” “nicking,” and “cleaving,” that may be present “in certain embodiments” of the invention. Ex. 1001, 6:56–7:1. However, as noted above, the claims recite “gRNA functionality comprising” only the associating and targeting functions. Thus, while a molecule may have additional functions such as cleaving a target polynucleotide, it need only exhibit the recited “associating” and “targeting” functions to have the “gRNA functionality” in claims 1 and 19. Our determination that “gRNA functionality” requires the recited “associating” and “targeting” functions, but not additional, unrecited functions such as cleaving, is also consistent with the parties’ position that the claim language has its plain and ordinary meaning. See Pet. 17; Resp. 24. The parties do not dispute the construction of any other terms, nor do we discern that any further claim construction is necessary to resolve the issues in this proceeding. See Nidec Motor Corp. v. Zhongshan Broad OceanMotor Co., 868 F.3d 1013, 1017 (Fed.

    “Second, even if those sequences were truncated, the record does not support Patent Owner’s argument that a POSA would doubt that they have gRNA functionality. Patent Owner’s argument is premised on Dr. Marshall’s testimony that these sequences “are truncated to a point that would render them nonfunctional.” Ex. 2025 ¶ 200. But the references he cites do not support that position. See Ex. 2025 ¶ 202 (citing Ex. 1033 (“Fu”); Ex. 2044 (“Cencic”); and Ex. 2045 (“Mali”)). To the contrary, Fu evidences that “truncated gRNAs, with shorter regions of target complementarity <20 nucleotides in length” are functional and that truncation to 17 nt is beneficial. Ex. 1033, Abstr.; see also id. at 283 (“[W]e found that [truncated] gRNAs with 17 or 18 nucleotides of complementarity generally function efficiently at the intended target site and have improved specificities.”). Cencic and Mali likewise do not suggest that a 17 nt VT domain would lack gRNA functionality. See Ex. 2025 ¶ 202 (citing Cencic as showing “truncated gRNA tests showed that a guide sequence of only 16 nucleotides” abolished cleavage activity); Ex. 2045, Supp. Fig. 10 (“1-3 bp 5’ [gRNA] 11 Patent Owner asserts that Dr. Furneaux “adopted the definition of ‘truncated gRNAs’ as those with ‘regions of target complementarity <20 nucleotides in length” in paragraph 79 of his opening declaration. Sur-reply 8 n. 1. We disagree. The testimony in paragraph 79 refers to the particular results in Fu. See Ex. 1003 ¶ 78 (citing Ex. 1033). We see nothing there that suggests Dr. Furneaux agrees with Patent Owner’s position that any gRNA with a VT region of less than 20 nt is truncated. truncations are indeed well tolerated, but larger deletions lead to loss of activity”). Accordingly, we credit Dr. Furneaux’s testimony (see, e.g., Ex. 1003 ¶ 78, Ex. 1059 ¶¶ 73–75) over the competing testimony offered by Dr. Marshall on these points.” slip op. at 24

    “Dr. Martin also provides consistent testimony on this issue. Snap IPR, Ex. 2003 ¶¶ 81–82. Put simply, the Specification’s disclosure is that the set of rules for multiple content packages includes an expected response, and actions are then performed based on whether an expected response is or is not provided. Moreover, as Dr. Almeroth testifies, neither the claims nor the Specification use the term “unexpected response”—rather the Specification only identifies an “expected response.” Snap IPR, Ex. 1022 ¶ 42. Accordingly, the disclosures in Table 1 and the Specification support Dr. Almeroth’s testimony that a person of ordinary skill would have understood that “the claimed ‘determin[e/ing]’ limitation requires what it plainly recites: ‘determin[e/ing] whether the received response matches the expected response[]’. . . .

Twitter PO Resp. 32. Patent Owner argues that “Twitter points back to its limitation 12.1 PALLAS evidence for the purported ‘content piece’” and also does not mention Yau for limitation 12.5 and 12.6 and “only conclusorily states that ‘PALLAS in view of Yau renders obvious triggering an exercise/test/quiz.’” Id. Patent Owner’s arguments overlook Twitter’s assertion, with Dr. Turnbull’s supporting testimony, that a person of ordinary skill in the art would have understood that Yau’s formal assessments are “tests with answers for comparing against learner’s responses to assess knowledge/performance/skill (contrasting with ‘un-assessed’ exercises whose responses are unchecked).” Twitter Pet. 43; Twitter IPR, Ex. 1003 ¶ 154.

Patent Owner also asserts that in the PALLAS-Yau combination, Twitter does not explain how a person of ordinary skill in the art would have combined the prior art in the manner Petitioner alleges. Twitter PO Resp. 42. Patent Owner argues that “PALLAS says nothing about forcing quizzes, tests, or exercises on its users without the users asking for such exercises,” and a person of skill would understand that the combined system still requires that a student select a learning activity and that PALLAS’s system should be unobtrusive because learners “may have small time slots to engage in learning.” Id.

Id. at 42–43 (citing Twitter IPR, Ex. 2013 ¶ 144). Patent Owner argues that because a learner may not have time to complete a test, a person of ordinary skill in the art would not be motivated to change PALLAS to trigger exercises/tests/quizzes based on location or time.

  • ScopeMotion to amend, grantedGranted

    “2. Enlarging Scope of Claims Patent Owner asserts that it proposes narrowing limitations in direct response to the grounds of unpatentability involved in this proceeding. See, e.g., Snap Mot. 3–4. Facebook argues Patent Owner is “improperly attempting to enlarge the scope of the original claims.” Facebook Pet. Opp. 1. Facebook asserts, “[i]f ‘an expected response’ means one or more expected responses, therefore, determining whether the received response ‘matches the expected response’ means that the received response must match [all of] the one or more previously-recited expected responses in the content package.” Id. at 3 (emphasis omitted). Facebook then argues “the term ‘predefined response’ is broader than ‘expected response,’” because “an ‘expected response’ does not include any conceivable or possible response; it is a response that is expected.” Id. at 4–5 (emphasis omitted). Twitter argues that “‘predefined response’ is broader than ‘expected response’ because a ‘predefined response’ can include any possible response as long as that response has been somehow defined in advance.” Twitter Pet. Opp. 2. We consider the amendments in view of the claim as a whole. Although the term “one predefined response” may be broader than “an expected response,” we also consider the amended portion “wherein the received response is expected if the received response matches one or more of the at least one predefined response,” and “the received response is unexpected if the received response does not match any of the at least one predefined response.” Unless the response had been predefined within the content package, any “received response” could not be considered “expected” under the claims, and the additional clause requires a match of the response with the predefined response to be deemed “expected.” This equates to an equivalent scope to the original claim. This is consistent with Dr. Martin’s testimony, which we credit, that he is not aware of a situation where the substitute but not original claims are infringed because “[t]he substitute claims would only be satisfied when a ‘predefined response’ in the substitute claims is an ‘expected response’ in the original claims.” Facebook IPR, Ex. 2023 ¶ 59.” slip op. at 136

    “none of the combinations in the Petition were previously presented. Further, there is no overlap between the arguments made during examination and the representations of the prior art in this proceeding. Therefore, with respect to Chen and Cook, the same or substantially the same art or arguments were not previously presented. Further, even if Chen is cumulative to Heer as alleged by Patent Owner, Petitioner demonstrates that the Examiner materially erred for the reasons explained below. As the parties indicate, the Examiner stated as reasons for allowance for the “independent claims,” that “the prior art of record does not teach: combining the multi-modal information for content portions associated and the proximal information for content portions associated with the user path to form a user profile having a unified representation.” See Pet. 85; Prelim. Resp. 26; Ex. 1002, 123. Patent Owner now argues that the primary difference between Heer (or Chen, if, as Patent Owner alleges, it is “cumulative” to Heer) and independent claims 1 and 10 is that the claims require using proximal information in the user profile. See Prelim. Resp. 26. But as discussed above (§ I.E.5), Patent Owner also admits that the asserted prior art at least separately teaches using proximal information and multi-modal information. See Prelim. Resp. 36–37 (arguing that “each” of the prior art references relied upon by Petitioner “relates to using either multi-modal information or proximal information, but not both”). Nevertheless, nothing in the prosecution history, including the Examiner’s reasons for allowance or citation and limited discussion of Heer with respect to dependent claims (Ex. 1002, 78–79, 123), shows that the Examiner was aware that Heer (even if it is cumulative to Chen) taught everything in the independent claims except for combining proximal information as part of the user profile. Also, the prosecution history does not show that Patent Owner informed the Examiner, or that the Examiner was aware, of Patent Owner’s current admission that the prior art “relates to using either multi-modal information or proximal information, but not both.” See Prelim. Resp. 36–37. Petitioner shows that the Examiner did not apply Heer as the primary basis for rejecting independent claims 1 and 10, which Petitioner essentially does here with respect to Chen. See Pet. 84 (arguing that “Heer was relied on, but only for dependent claims 9 and 18”) citing Ex. 1002, 78–79); see Advanced Bionics, Paper 6 at 10–11 & n.10 (reasoning that Becton Dickinson factor c, “the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection,” is a material error factor). And Petitioner sufficiently shows that “Chen and Cooke were not previously presented” during prosecution. Pet. 84. As summarized above, Petitioner sufficiently shows that Chen, with Chi and other secondary references, suggests combining multi-modal information with proximal information such as surrounding text associated with links and images wherein Chen specifically teaches flexibly employing all manner of such multi-modal information to aid in assigning users to clusters. See supra § II.E.; Ex. 1004 ¶¶ 16, 18, 22; Advanced Bionics, Paper 6 at 9–11 & n.10 (reasoning that Becton Dickinson factor f, “additional evidence and facts presented in the petition warrant reconsideration of the prior art or arguments,” and Becton Dickinson factor e, the extent the Petition shows error, are a material error factors).” slip op. at 36

And though Patent Owner attempts to distinguish Queen 1990 as describing “a consensus framework from many human antibodies,’ not all as in the ’213 patent,’” it presents no argument as to why we should interpret the claim in this manner. 11 Kabat et al., Sequences of Proteins of Immunological Interest: Tabulation and Analysis of Amino Acid and Nucleic Acid Sequences of Precursors, V- Regions, C-Regions, J-Chain, T-Cell Receptor for Antigen, T-Cell Surface Antigens β2-Microglobulin, Major Histocompatibility Antigens, Thy-1 Complement, C-Reactive Protein, Thymopoietin, Post-Gamma Globulin, and α2-Macroblobulin, 41–175 (4th Ed. 1987). Ex. 1052. See PO Resp. 47. Moreover, in a parallel proceeding involving the same patent, Patent Owner did not dispute that the reference to “all sequences” in the patent, “refer[s] to all known sequences and there’s no dispute . . . that was really synonymous with Kabat 1987.” See IPR2017-01374 Paper 82, Tr. 15:4–16:4; see Ex. 1202 ¶ 157; Ex. 2105 ¶¶ 24–25; Ex. 2107 ¶¶ 18–19; Ex. 1198, 56:20–61:24; Ex. 1199, 27:14–28:13, 29:25–36:2, 57:1–58:6, 115:7–17, 165:17–169:9. Indeed, in a similar parallel proceeding, counsel for Patent Owner acknowledged that the term “all human immunoglobulins” refers to “all reasonably available[,] all known at the time of the invention.” IPR2017-01373, Paper 83, 47:21–48:5. Accordingly, we adopt the parties’ proposed construction, with a clarifying modification, specifically, “a human variable domain which comprises the most frequently occurring amino acid residues at each location in all human immunoglobulins of any particular subclass or subunit structure, as set forth in Kabat 1987.”” slip op. at 13

    “lacks immunogenicity compared to a non-human parent antibody upon repeated administration to a human patient.” In our institution decision, we determined that this claim language “refer[s] to a humanized antibody having reduced immunogenicity in a human patient as compared to its non-humanized parent antibody.” Dec. 10–12. Neither party disputes this interpretation. See PO Resp. 19; Pet. Reply 5–6. Consistent with claim 63’s express comparison between the immunogenicity of the claimed humanized antibody and that of its non-human parent, the Specification states that one object of the invention is to “to provide methods for the preparation of antibodies which are less antigenic in humans than non-human antibodies but have desired antigen binding and other characteristics and activities.” Ex. 1001, 4:24–28. The Specification similarly states that embodiments within the scope of the claims have “low immunogenicity,” or are designed to “minimize the potential immunogenicity of the resulting humanized antibody in the clinic.” Id. at 52:54–58, 61:56–61. Moreover, with reference to claim 63 in particular, Patent Owner points to the ’272 application as “explain[ing] that the purpose of humanizing antibodies using its consensus sequence approach is to reduce immunogenicity versus the non-human parent antibody.

In light of the above, we do not alter our prior determination that “[a] humanized antibody which lacks immunogenicity compared to a non-human parent antibody upon repeated administration to a human patient,” refers to a humanized antibody having reduced immunogenicity in a human patient as compared to its non-humanized parent antibody.” slip op. at 14

    “recites “in the absence of an anthracycline derivative.” In the Petition and the Preliminary Response, neither party proposed a construction for that term. Patent Owner, however, argues that “[e]ven if a person of ordinary skill would have chosen to combine an anti-ErbB2 antibody and a taxoid, there is no reason an ordinarily skilled artisan would have avoided anthracyclines as part of that treatment.” Prelim. Resp. 52 (emphasis added). In our Decision denying institution, we agreed with Patent Owner, stating that evidence of the record is “insufficient to suggest that an ordinary artisan would have avoided anthracyclines while pursuing the combination therapy with anti-ErbB2 antibody and a taxoid in a treatment regimen for humans.” Dec. 10 (emphasis added). In its Request for Rehearing, Petitioner contends that we erred in interpreting the limitation “in the absence of an anthracycline derivative” as requiring “avoidance” of an anthracycline derivative. Reh’g Req. 6. According to Petitioner, this term “is a negative limitation that is satisfied by anti-ErbB2 antibody–paclitaxel combinations that do not include an [anthracycline] derivative.” Id. at 5. After reconsidering the current record, we find Petitioner’s argument persuasive. In particular, because Baselga ’94 suggests a therapeutic composition consisting of an anti-ErbB2 antibody and paclitaxel, and does not suggest that doxorubicin must necessarily be included as part of the same treatment regimen, we are persuaded that the reference satisfies the limitation “in the absence of an anthracycline derivative.” Cf. Upsher-Smith Labs., Inc. v. Pamlab, L.L.C., 412 F.3d 1319, 1322 (Fed. Cir. 2005) (concluding the prior art anticipates a claim requiring a composition “essentially free of antioxidants,” because the prior art teaches “optional inclusion” of antioxidants, “despite no express teaching to exclude the antioxidants”).” slip op. at 17

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundInstituted

    “Petitioner, however, points to other evidence to show that prior art teaches an ordinary artisan to combine an anti-ErbB2 antibody with a taxoid. Specifically, Petitioner refers to Baselga ʼ94 for teaching that, in mouse xenografts, “individual treatment with either anti-HER2 4D5 or paclitaxel alone resulted in 35% growth inhibition whereas the combination ‘resulted in a major antitumor activity with 93% inhibition of growth’ without increasing toxicity.” Id. at 45 (citing Ex. 1005 at 4). Similarly, Baselga ’96, citing Baselga ’94, teaches that “[i]n preclinical studies, both in vitro and in xenografts, rhuMAb HER2 markedly potentiated the antitumor effects of several chemotherapeutic agents, including … paclitaxel without increasing their toxicity.” Id. at 44 (quoting Ex. 1004, 15). Based on these teachings, we are persuaded that an ordinary artisan would have had a reason to treat HER2-positive breast cancer patients with a combination of rhuMAb HER2 and a taxoid.” slip op. at 12

    “Patent Owner argues that Exhibit 2029, which states that “breast cancers that overexpress p185 [i.e., HER2] will not respond well to Taxol,” teaches away from the claimed combination therapy. Prelim. Resp. 51 (citing Ex. 2029,5 1362). We are not persuaded on this record. In an obviousness inquiry, we must analyze the prior art as a whole, and not individually. See In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (explaining that the question is “whether there is something in the prior art as a whole to suggest the desirability, and thus the obviousness, of making the combination”). Other evidence of record shows paclitaxel had been approved for treating breast cancer (see, e.g., Ex. 1025, 10), demonstrates synergy of paclitaxel and an anti-ErbB2 antibody in human breast cancer xenografts (see, e.g., Ex. 1005, 4; Ex. 1004, 15), and suggests clinical trials of the combination therapy (see, e.g., Ex. 1005, 4; Ex. 1004, 15). Weighing all evidence of record, we are not persuaded that prior art as a whole teaches away from combining paclitaxel and an anti-ErbB2 antibody in treating HER2-positive cancers.” slip op. at 14

    “art. For the purpose of this decision, we accept Petitioner’s undisputed contention that: [a] person of ordinary skill in the art would have a Ph.D. in chemistry, medicinal chemistry, pharmacology, or a related field, and at least one year of industrial exposure to drug discovery, drug design, and synthesis. In lieu of an advanced degree, the individual may have additional years of industry experience, including, for example, in drug discovery, drug synthesis, and structure-activity work. Pet. 6 (citing Ex. 1003 ¶ 23); see Resp. 6. Based on our review of the ’650 patent, the types of problems and solutions described in the ’650 patent and cited prior art, we adopt Petitioner’s definition of a person of ordinary skill in the art at the time of the claimed invention. We note that the applied prior art also reflects the appropriate level of skill at the time of the claimed invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 7

    “the broadest reasonable construction in light of the specification of the patent in which they appear. See Cuozzo Speed Techs., LLC v. Lee, 136 S.Ct. 2131, 2144–46 (2016) (upholding the use of the broadest reasonable interpretation standard); 37 C.F.R. § 42.100(b). Under that standard, and absent any special definitions, we give claim terms their ordinary and customary meaning, as would be understood by one of ordinary skill in the art at the time of the invention. See In re Translogic Tech., Inc., 504 F.3d 1249, 1257 (Fed. Cir. 2007). Only those terms which are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999). Petitioner submits that the “claims in the ʼ650 patent are presumed to take on their ordinary and customary meaning based on the broadest reasonable interpretation of the claim language.” Pet. 6. Patent Owner “does not dispute Petitioner’s position that no claim terms require construction, which the Board also accepted for purposes of institution.” Resp. 7 (citing Pet. 6; Inst. Dec. 7). In our Institution Decision, we determined that “no claim term requires express construction.” Inst. Dec. 7. After reviewing the entire record developed during trial, we affirm our determination from the Institution Decision that no claim term requires express construction to resolve the parties’ dispute.” slip op. at 8

  • Expert testimonyPetitioner expert discountedPatent owner expert creditedDecided for patent owner

    “Following our weighing of the experts’ testimony, we find that Dr. Roush’s testimony better addresses the issue at hand and we credit that testimony over Dr. Patterson’s testimony. Dr. Patterson opines generally that the “presence of two hydroxyl groups around the left most aromatic ring . . . would have created a product likely to have decreased oral bioavailability compared to tolterodine because of its hydrophilicity and thus lower than acceptable lipophilicity” (Ex. 1003 ¶ 112), and that it “would [have been] a matter of routine experimentation” to confirm that 5-HMT could have significantly less bioavailability than its parent, tolterodine” (Ex. 1003 ¶ 115). Dr. Patterson, however, did not perform any experiments to confirm 5-HMT’s oral bioavailability, and cites to no further evidence to support his opinions. See Ex. 2022 ¶ 92; compare Brynne (Ex. 1011) discussed supra § II.D.1. Dr. Roush, on the other hand, conducts an analysis of the compound under the “Rule of 5” to determine that “5-HMT does not meet a single factor, much less two, of the rule” thus teaching the skilled artisan “away from concluding that 5-HMT had an oral absorption problem.” Resp. 28–29 (citing Ex. 2022 ¶¶ 56–58, 87, 92). At oral hearing, Patent Owner restated that the analysis under the Rule of 5 indicates that 5-HMT was “not even close to being a problem . . . for all four of these properties, 5-HMT says there’s no red flags; there’s no problem,” and that “Dr. Patterson admitted in his deposition, 5-HMT does not violate the Rule of Five.” Tr. 67:35–68:3; 68:17–21; see Ex. 2020, 180:14–181:14. Regarding Petitioner’s reliance on the statement in Brynne that “[t]olterodine is tenfold more lipophilic than 5-HM[T], and consequently tolterodine penetrates membranes more rapidly,” Patent Owner does not appear to dispute the substance of that statement. Although such a statement illustrates a relative relationship between the lipophilicity of 5-HMT and tolterodine, it does not demonstrate that the lipophilicity of 5-HMT would have presented an absorption problem that would have led one of ordinary skill in the art to modify 5-HMT. Even if 5-HMT were considered by one of ordinary skill in the art to be less lipophilic than tolterodine, and thereby less rapidly absorbed, the record lacks sufficient evidence regarding the actual properties of 5-HMT for us to conclude that 5-HMT’s lipophilicity would have presented a bioavailability problem.21 For these reasons, Petitioner’s assertion that 5-HMT “may have bioavailability concerns” that would have prompted one of ordinary skill in the art to modify 5-HMT is unpersuasive.

    “On the complete record before us, we are unpersuaded that Petitioner carries its burden of demonstrating that 5-HMT has a bioavailability problem that would have motivated one of ordinary skill in the art to modify its structure. Regarding the lipophilicity profile of 5-HMT, Petitioner does not provide, or attempt to provide, any actual (as opposed to relative) data concerning the bioavailability of 5-HMT. Cf. supra § II.D.2 (Brynne comparing lipophilicity of tolterodine to lipophilicity of 5-HMT). Although data is not required, and although we do not find that absence of data alone to be fatal to Petitioner’s position on this issue, the absence of any data concerning the actual bioavailability of 5-HMT leaves Petitioner’s argument solely supported by expert testimony. We now turn to the contradictory statements of the parties’ experts. Following our weighing of the experts’ testimony, we find that Dr. Roush’s testimony better addresses the issue at hand and we credit that testimony over Dr. Patterson’s testimony. Dr. Patterson opines generally that the “presence of two hydroxyl groups around the left most aromatic ring . . . would have created a product likely to have decreased oral bioavailability compared to tolterodine because of its hydrophilicity and thus lower than acceptable lipophilicity” (Ex. 1003 ¶ 112), and that it “would [have been] a matter of routine experimentation” to confirm that 5-HMT could have significantly less bioavailability than its parent, tolterodine” (Ex. 1003 ¶ 115). Dr. Patterson, however, did not perform any experiments to confirm 5-HMT’s oral bioavailability, and cites to no further evidence to support his opinions.
