    “Principles of Law A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which that subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). “The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” Id. at 416. “If a person of ordinary skill can implement a predictable variation, § 103 likely bars its patentability.” Id. at 417. We are, nevertheless, cautioned not to “rel[y] on hindsight reasoning to piece together elements to arrive at the claimed invention.” In re NTP, Inc. 654 F.3d 1279, 1299 (Fed. Cir. 2011) (“Care must be taken to avoid hindsight reconstruction by using the patent in suit as a guide through the maze of prior art references, combining the right references in the right way so as to achieve the result of the claims in suit.” (internal quotations and citations omitted)). Thus, a finding of obviousness, “cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” KSR, 550 U.S. at 418 (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Accordingly, a party petitioning the Board for a determination of obviousness must show that “a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” Procter & Gamble Co. v.

Noting that the two compounds had 1) complementary effects in delaying cell cycle progression; and 2) synergistic cytotoxic and antitumor effects, Akinaga expressly suggests the combination of UCN-01 and DNA-damaging agents for cancer chemotherapy. Id. Seynaeve establishes that UCN-01 inhibits multiple tyrosine kinases in human breast cancer cells coincident with promoting cell cycle arrest. Dec. 28–29, 34–35; Ex. 1014. Accordingly, “Seynaeve proposes a link between UCN-01’s inhibitory effects on tyrosine kinases and its inhibitory effects on the cell cycle.” Dec. 29.8 Akinaga further suggests combining a chemotherapeutic DNA damaging agent with UCN-01 because the two compounds cause delays in different stages of the cell cycle and result in synergistic cytotoxic and antitumor effects, whereas Seynaeve examines the effects of UCN-01 on the cell cycle of human carcinoma cells and shows that UCN-01 is a tyrosine kinase inhibitor.

We instead credited the testimony of Petitioner’s expert, Dr. Eastman that “[b]ecause v-Src and c-Src have similar structures, compounds that inhibit the tyrosine kinase activity of v-Src generally inhibit c-Src as well. Thus, a person of ordinary skill would have understood that an inhibitor of v-Src would also inhibit the c-Src protein present in A431 cells and other human tumors.” Id. at 33 (quoting Ex. 1002 ¶ 202).

    “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.

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).

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).

Resp. 48 (citing Pet. 24; Ex. 1014 ¶¶ 45, 52; Ex. 1008, 707, Fig. 8; Ex. 2002 ¶¶ 92, 160–61). Accordingly, we agree with Patent Owner that this new testimony does not address the question of in vivo bioavailability, which requires an oil-based fulvestrant formulation. Id. (citing Ex. 1011, 28; Ex. 2162, 28; Ex. 2001 ¶¶ 176, 185, 234–43); see also Ex. 1046, 729 (Examiner finding that “the unexpected solubility and the bioavailability of using the specific solvent mixture as recited have been demonstrated”). Patent Owner asserts that Petitioner attempts to rewrite the plain disclosure of McLeskey, by raising opinion testimony directed to what the McLeskey authors may have “hoped” to achieve. Prelim. Resp. 17 (citing Pet. 54). We agree. As Patent Owner argues, the testimony of Dr. El-Ashry “reverses McLeskey’s conclusion of ‘treatment failure’ . . . and instead claims it was a ‘successful treatment.’” Id. at 3. We accord little weight to the testimony of Dr. El-Ashry, which was executed nearly two decades after McLeskey was published, because it runs counter to the statement of McLeskey within its four corners—“treatment failure,” which was reported at or near the time of the experiments.” slip op. at 28

    “Principles of Law A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which that subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). “The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” Id. at 416. “If a person of ordinary skill can implement a predictable variation, § 103 likely bars its patentability.” Id. at 417. We are, nevertheless, cautioned not to “rel[y] on hindsight reasoning to piece together elements to arrive at the claimed invention.” In re NTP, Inc. 654 F.3d 1279, 1299 (Fed. Cir. 2011) (“Care must be taken to avoid hindsight reconstruction by using the patent in suit as a guide through the maze of prior art references, combining the right references in the right way so as to achieve the result of the claims in suit.” (internal quotations and citations omitted)). Thus, a finding of obviousness “cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” KSR, 550 U.S. at 418 (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Accordingly, a party petitioning the Board for a determination of obviousness must show that “a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” Procter & Gamble Co. v. Teva Pharm. USA, Inc., 566 F.3d 989, 994 (Fed. Cir. 2009) (quoting Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1361 (Fed. Cir. 2007)). D.” slip op. at 21

  • PTAB / AIA Trials › Discretionary denial › General Plastic (serial petitions)Denied

    “Patent Owner requests that we exercise our discretion to deny the Petition on the basis that it uses a previous Board decision “as a ‘roadmap’ to address challenges that were advanced, unsuccessfully,” in the Mylan IPR. Prelim. Resp. 5 (quotation omitted). The Mylan IPR, however, involved a different petitioner (Mylan) and, to some extent, a different record. Based on the particular facts of this case, we decline to issue a discretionary denial and, instead, consider the Petition on its merits. Nevertheless, we approach this case cognizant that, in the Mylan IPR, we denied institution of inter partes review of all of the claims challenged here. We recognize, moreover, that our prior Mylan Decision addressed essentially the same factual inquiry centered on substantially the same asserted prior art references. We accept, therefore, Petitioner’s view that the nub of this dispute is whether “[f]our differences” set forth in the Petition overcome the shortcomings we previously identified in the Mylan Decision. Pet. 9–11; see Ex. 1011, 19–30 (Mylan Decision, including our prior analysis of essentially the same issues raised in the instant Petition).” slip op. at 23

  • Prior constructionPrior construction adoptedDecided for petitioner

    “interpreted according to their broadest reasonable construction in light of the specification of the patent in which they appear. 37 C.F.R. § 42.100(b); Cuozzo Speed Techs., LLC v. Lee, 136 S. Ct. 2131, 2144–46 (2016) (upholding the use of the broadest reasonable interpretation standard). Under that standard, we presume that a claim term carries its “ordinary and customary meaning,” which “is the meaning the term would have to a person of ordinary skill in the art in question” at the time of the invention. In re Translogic Tech., Inc., 504 F.3d 1249, 1257 (Fed. Cir. 2007). Only terms that are in controversy need be construed, and only to the extent necessary to resolve the controversy. Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999). In the Mylan IPR, we determined the meaning of several claim terms of the ’680 Patent. See Ex. 1011, 15–18. The parties contend that the terms of the ’680 Patent claims should be interpreted in accord with our prior construction. See Pet. 17–18; Prelim. Resp. 19. For the reasons set forth in the Mylan Decision, we agree. See Ex. 1011, 16–18. C.” slip op. at 21

  • Skill levelOther

    “Person of Ordinary Skill in the Art. The parties propose similar, albeit non-identical, definitions of one of ordinary skill in the art, both of which are consistent with the high level of ordinary skill demonstrated by the prior art asserted in the Petition. See Pet. 16–17; Prelim. Resp. 18–19. Discerning no present conflict between the parties’ proposals, we rely on the level of ordinary skill in the art of developing and treating hormonal-dependent diseases of the breast as demonstrated by the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 20

    “As discussed above, Grobelny teaches that the inclusion of a solubilizing group to a protease inhibitor compound having low water solubility for the purposes of improving water solubility and bioavailability of those compounds. Ex. 1022, 74:1116. In this regard, Grobelny provides general guidance for using a solubilizing agent phosphate ester salt to solve the solubility problem of amprenavir. However, the success of discovering fosamprenavir was not discovering a compound with improved solubility. 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
