    “The facts of the case at hand provide a stark contrast. As we have found above, while the prior art recognized rapamycin as a promising immunosuppressant, it was only one among many possible lead compounds. Furthermore, the prior art shows that chemists were pursuing a number of avenues to increase solubility, including making derivatives but also other approaches such as formulation techniques or prodrugs. And most tellingly, in contrast to Bristol-Myers Squibb where the experts agreed on the type and location of the potential substituents, here the experts diverge significantly. As discussed above, we credit the testimony of Novartis’ experts over Par’s, and find that the options of substituent and substituent position would not have been as narrow as those proposed by Par. In sum, we find that the person of ordinary skill in the art at the time the invention was made would have been faced with a large number of decision points along the lead compound analysis proposed by Par. The number of potential compounds encompassed by this decision tree is unclear, but would be far larger than the three compounds Dr. Jorgensen discusses. Only by making the “right” choice at each step would the skilled artisan arrive at everolimus, the compound of claim 10 and the basis of Par’s obviousness challenge. In light of these facts, we cannot conclude that the options faced would have been—in the words of the Federal Circuit—finite, small, or easily traversed. We, therefore, cannot conclude that the compound of claim 10, and by extension, the compounds of claims 1–3, would have been obvious to one of skill in the art as of October 1992.” slip op. at 35

    “Par contends, supported by the testimony of Dr. Jorgensen, that a person of ordinary skill in the art at the time of the invention would generally have a Ph.D. in organic chemistry or medicinal chemistry or physical chemistry or a related field, or a Masters or Bachelor degree in chemistry or a related field and at least three years’ experience in drug discovery and design. Pet. 16 (citing Ex. 1003 ¶ 45). Novartis’ experts, with insubstantial exceptions, agree with Dr. Jorgensen’s recitation. Ex. 2092 ¶ 22 (Klibanov); Ex. 2093 ¶¶ 47–48 (Roush).

    “Based on our review of the entirety of the record, we cannot conclude, as Par contends, that the C40 hydroxyl group would be the obvious, optimal, or preferred location for substitutions to rapamycin. Dr. Jorgensen’s testimony to that effect is premised on his assertion that a person of ordinary skill in the art would have first narrowed the group of possible substitution positions to the C10, C28, or C40, because those are the hydroxyl groups of rapamycin. Ex. 1003 ¶ 142 (“person of ordinary skill in the art would have focused on hydroxyl groups on rapamycin as initial targets for modification.”). This statement, however, is based only on Dr. Jorgensen’s statement that the reactions of hydroxyl groups are “among the most fundamental and elementary reactions taught in beginning organic chemistry courses.” Id. Dr. Jorgensen provides no objective, documentary evidence that would indicate that starting with hydroxyl groups was an accepted rule followed by medicinal chemists in the field. To the contrary, Dr. Roush testifies that Dr. Jorgensen’s focus on rapamycin’s hydroxyl groups is inconsistent with the prior art as a whole, and provides multiple citations to the documentary evidence in the record supporting his testimony. Ex. 2093 ¶¶ 197, 206–216 (citing prior art modifications at the C9, C26, C27, C28, and C32 positions). For example, Ondeyka14 discloses demethylation of the methoxy group at rapamycin’s C29 position, while Caulfield15 discloses oxime substitutions at C32.16 We have weighed the testimony of Drs. Jorgensen and Roush on this point, and find Dr. Roush’s to be the more credible. While we agree with Par that a person of ordinary skill in the art would have considered rapamycin’s C40 position as a candidate for substitution, that site must be evaluated as one potential substitution site among many that were being modified in the field at the time of the invention.” slip op. at 24

    “obviousness challenge. In light of these facts, we cannot conclude that the options faced would have been—in the words of the Federal Circuit—finite, small, or easily traversed. We, therefore, cannot conclude that the compound of claim 10, and by extension, the compounds of claims 1–3, would have been obvious to one of skill in the art as of October 1992. With respect to the second ground of unpatentability, pertaining to the method of treatment claims 8 and 9, Par’s obviousness arguments are premised on the conclusion that everolimus would have been obvious. See Pet. 48–51 (“claims 8 and 9 would have been obvious to a person of ordinary skill in the art in view of the art that makes the 40-O-2- hydroxyethyl-rapamycin derivative obvious”). As we conclude that everolimus has not been shown to be obvious, we reach the same conclusion as to the methods of claims 8 and 9. The addition of Hughes to the ground of unpatentability does not provide any of the teachings we found lacking from the art asserted in the first ground of unpatentability. As we have concluded that Par’s articulated lead compound analysis is insufficient to establish the obviousness of any of the challenged claims, we need not reach, and do not evaluate, the objective indicia of obviousness submitted by Novartis.

Rather, the success was finding a compound that had the requisite bioavailability to treat HIV and minimize the development of drug-resistance mutations in patients.6 The evidence of record does not support a finding that a person of ordinary skill in the art would have had a reasonable expectation of success in developing fosamprenavir, a protease inhibitor prodrug having the same or improved bioavailability as its parent drug.” slip op. at 16

    “On this record, and under our standard for final decisions in inter partes reviews, we are unpersuaded by Petitioner’s argument. Regardless of whether prodrugs generally were known in the art, or were part of an ordinarily skilled artisan’s arsenal at the time of the invention, Petitioner has not established that such an ordinarily skilled artisan would have embarked on a prodrug approach to modify 5-HMT. As we have discussed above, Petitioner has not established that bioavailability of 5-HMT was a problem and, therefore, Petitioner cannot reasonably establish that one of ordinary skill in the art would have turned to prodrug development to solve an undefined problem. As Patent Owner points out, and as we agree, “prodrug development requires monitoring the toxicity, bioavailability, receptor affinity, pharmacokinetics, and pharmacodynamics of not only one, but two, compounds – the prodrug and the desired active compound – making the development process even more complex, time consuming, and expensive.” PO Resp. 30 (citing Ex. 2022 ¶¶ 41–49; Ex. 2021 ¶¶ 82–85).

    “Petitioner’s arguments in the Reply and at oral hearing appear to be, at best, a variation on a nominal position taken in footnote 4 of the Petition which provides: “Because the patent to the 5-HMT compound was available as of November 1997 . . . a person of skill in the art in 1998 would have been motivated to research and investigate a different compound.” Pet. 45 n.4 (citing Ex. 1003 ¶ 136). Footnote 4, however, was part of Petitioner’s Ground II argument that Johansson and its divisional application make it “more predictable that the prodrug of 5-HMT in a fumarate salt would be successfully achieved.” Id. But in the Reply, and at oral hearing, Petitioner leverages this footnote into a new argument that the oral administration of 5-HMT would have been discouraged by the existence of a prior patent disclosing the compound. Reply 9–10; Tr. 28:13–29. Such a shift in position “is foreclosed by the statute, [Federal Circuit] precedent, and Board guidelines.” Wasica Fin. GmbH v. Cont’l Auto. Sys., Inc., 853 F.3d 1272, 1286–87 (Fed. Cir. 2017). Additionally, we are not made aware of any authority supporting Petitioner’s argument that one of ordinary skill in the art would not have pursued oral administration of 5-HMT due to the existence of a patent on the 5-HMT compound. See also Tr. 65:23–29 (Patent Owner’s assertion that there was “no case law suggesting that persons of ordinary skill are focused on patents in deciding which steps to make”). Considering the untimely development of Petitioner’s position, the absence of factual underpinnings,19 and the lack of legal precedent, we are unpersuaded that we need to give considerable weight to Petitioner’s argument regarding the prior patent. 19 Paragraph 136 of Dr. Patterson’s Declaration, relied on to support footnote 4 of the Petition, consists of the bald assertion that “[b]ecause the 5-HMT compound would have been covered by this patent and its U.S. counterpart, a skilled drug designer and developer would recognize the need to make some changes to avoid the patent.” Ex. 1003 ¶ 136. We accord little to no weight to Dr. Patterson’s conclusory statement. See 37 C.F.R. §42.65(a).” slip op. at 23

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “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.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundReasonable expectation not foundNot shown unpatentable

    “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.
