    “In the Petition, Petitioners assert that no terms of the challenged claims require construction. Pet. 22. However, Petitioners note that a person of skill in the art would have understood that “rituximab,” recited in claim 1, is “a CD20 antibody that binds to the CD20 antigen on human B lymphocytes.” Pet. 22–23. Indeed, claims 5 and 9 recite “an antibody that binds to the CD20 antigen on human B lymphocytes” and explain that “the CD20 antibody is rituximab.” Id. at 23. In the Institution Decision, we agreed with Petitioners that no claim terms required construction for purposes of that decision. Dec. 5 (citing See Vivid Techs., Inc. v. Am.

  • Skill levelSkill level board ownOther

    “The proposed definitions asserted by Petitioners and Patent Owner suggest that the level of skill in the art is considerably high. Petitioners’ definition is more limiting than Patent Owner’s definition in that it requires, for example, the person of ordinary skill in the art to have more years of experience in treating RA patients and an understanding of “all of the available and proposed methods of treating RA and other auto-immune disorders … and how they work to treat such disorders.” Pet. 24. Based on the record as a whole, we determine that a person of ordinary skill in the art is not so limited. The invention and the cited references are directed to standard and proposed methods of treating RA and not all “other auto-immune disorders.” In terms of years of experience, we recognize rheumatology as a specialized area of medicine, wherein acquiring at least three years of experience would be sufficiently significant. Accordingly, we find that the record as a whole supports defining the level of ordinary skill in the art as: a practicing rheumatologist with a medical degree (M.D. or equivalent) and: (i) at least three years of experience treating RA patients; (ii) an understanding of the immunology and the pathophysiology of RA; and (iii) an understanding of the available and proposed methods of treating RA, including relevant clinical trials for such treatment. We also note that the applied prior art 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 9

    “under 35 U.S.C. § 102(b). Even assuming that Exhibit 1056 authenticates Exhibit 1055 and establishes that the reference was online on January 23, 1998, our determination whether Exhibit 1055 was publicly accessible prior to the critical date requires further inquiry. That is, we must determine whether Petitioners made a satisfactory showing that the reference was “disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art exercising reasonable diligence, can locate it.” SRI Int'l, Inc., 511 F.3d at 1194. For example, the Federal Circuit has explained “evidence that a query of a search engine before the critical date, using any combination of search words, would have led to the [reference] appearing in the search results” is probative of public accessibility. Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1350 (Fed. Cir. 2016). In this regard, Petitioners assert only that “Genentech’s website was organized such that the label could be easily located. Therefore the label was broadly disseminated and publicly accessible before May 1998 to anyone with a browser and an Internet connection.” Pet. 18 n.2. That assertion is not further explained or accompanied by citation to any evidence supporting Petitioners’ contention about Genentech’s website. Nor have Petitioners offered evidence indicating that persons interested and ordinarily skilled in treating rheumatoid arthritis would have identified and visited Genentech’s website before the critical date, and in doing so, would have searched for rituximab drug information, a product newly manufactured and indicated for the treatment of non-Hodgkin’s lymphoma.

This assertion is inadequate to supply the claim limitations not asserted to be taught or suggested by the combined prior art.

    “We agree with Patent Owner (PO Resp. 38) that, given Kohn 1991’s teaching that “stringent steric and electronic requirements exist for maximal anticonvulsant activity in this class of compounds” (Ex. 1012, 2447), the expected substantial change to the conformation of the overall molecule is significant evidence that an ordinary artisan would not have been motivated to replace the methoxyamino group of compound 3l, the most potent compound taught in Kohn 1991, with a methoxymethyl group. In sum, we acknowledge Dr. Wang’s testimony, discussed above, that due to a methoxyamino group’s potential synthetic and stability issues, and uncommonness in commercial pharmaceuticals, an ordinary artisan may have had a reason to replace such a group with a more common and acceptable moiety, such as a methoxymethyl group, in chemical compounds generally. Nonetheless, as also discussed above, the evidence advanced by Patent Owner shows that, as to the specific FAA compounds of Kohn 1991, an ordinary artisan would have understood that compound 3l’s methoxyamino moiety was considered a basic C(α)-amino substituent that conferred significant activity to the compound, and replacement of that moiety with other substituents would have led to a reduction in activity. As also discussed above, Kohn 1991 teaches that “stringent steric and electronic requirements exist for maximal anticonvulsant activity in this class of compounds” (Ex. 1012, 2447), whereas an ordinary artisan would have understood that substituting a methoxymethyl group for the methoxyamino group of Kohn 1991’s compound 3l would result in a compound with a significantly different conformation and biological activity. Thus, assessing Petitioner’s evidence of a more general motivation for substituting a methoxymethyl group for the methoxyamino group of compound 3l, against Patent Owner’s evidence specifically suggesting that an ordinary artisan would not have viewed the posited substitution as being desirable, we find that the weight of the evidence significantly favors Patent Owner’s position. Overall, the evidence before us indicates that an ordinary artisan lacked motivation, as well as a reasonable expectation of success, for making the specific substitution to Kohn 1991’s compound 3l, required to arrive at lacosamide. That is, we agree with Patent Owner that Petitioner has not shown sufficiently that the prior art of record would have suggested making the specific modification to compound 3l required to yield lacosamide.” slip op. at 23

Patent Owner’s witness on this issue, Dr. Bazil,20 testifies as follows: For many of my patients, lacosamide is a very important option, and it certainly fills a need in those patients who require a drug with the unique combination of properties as lacosamide possesses. Thus, lacosamide exhibits its biggest advantages in refractory patients. I have had numerous patients who were able to successfully control their seizures with lacosamide, but who had failed to do so previously with other antiseizure drugs. As director of Columbia’s Epilepsy Center, I have also heard many success stories from other neurologists about patients whose seizures were not controlled by other AEDs but were controlled when they switched to lacosamide.

Ex. 1002, ¶ 13 [Wang Decl.]. The POSA would also include a person having a Bachelor’s or Master’s degree (organic chemistry or medicinal chemistry) if such a person had more years of experience in medicinal chemistry and the development of potential drug candidates. Id. With experience in drug development, the POSA would have an appreciation of the diseases and ailments a particular drug candidate is intended to treat, but would not necessarily be a medical doctor or clinician. The POSA would know how to evaluate the physical and biological properties of chemical compounds and would be able to conduct, or otherwise have access to resources that could conduct, in vitro and in vivo evaluations of biological and toxicity properties of chemical compounds. Id. Pet. 12. Patent Owner does not controvert Petitioner’s characterization of the relevant art, or the level of ordinary skill in that art, nor does Patent Owner advance a specific assertion of its own as to the level of ordinary skill. See, generally, PO Resp. Accordingly, when evaluating the parties’ contentions regarding the scope and content of the prior art, and the differences between the prior art and the challenged claims, we take into consideration Petitioner’s assertions regarding the level of ordinary skill. We also consider that the cited references provide evidence as to the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 11

    “However, as noted above, Petitioners sought in their Reply to supplement the original obviousness rationale over Sallmann and Ogawa in the Petition by advancing new evidence supporting “further motivation” for including tyloxapol in bromfenac formulations. See, e.g., Reply 8–9. Accordingly, Patent Owner persuades us that the evidence allegedly supporting Petitioners’ assertions of “further motivation” is impermissibly raised for the first time in the Reply. See 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in the corresponding opposition or patent owner response.”); see also Intelligent Bio-Systems, Inc. v. Illumina Cambridge Ltd., 821 F.3d at 1369–70 (Board did not err or abuse its discretion in declining to consider new contentions and evidence in Reply advanced to supplement unpatentability rationale presented in Petition).
