      “with regard to claim 17. Nonetheless, we are not persuaded by Petitioner’s contentions. Rather, we find that the ’239 patent contains a sufficient written description of an oral dosage form containing “at least 10% zoledronic acid.” The specification describes a full panoply of zoledronic acid concentrations. Liquid compositions may contain “about 10% (w/v) to about 15% (w/v), about 15% (w/v) to about 20% (w/v), about 20% (w/v) to about 30% (w/v), about 30% (w/v) to about 40% (w/v), or about 40% (w/v) to about 50% (w/v) of zoledronic acid.” Ex. 1003, 10:25–28. Solid dosage forms may contain “at least about 10% (w/w), at least about 20% (w/w) . . .” up to “at least about 80% [w/w]” zoledronic acid. Id. at 10:30–32. Solid dosage forms also are described as containing zoledronic acid in ranges beginning from “about 10% (w/w) to about 30% (w/w), about 10% (w/w) to about 20% (w/w) . . .” all the way up to a range of “about 80% (w/w) to about 90% (w/w).” Id. at 10:32–39. The breadth of zoledronic acid concentration ranges disclosed is more comprehensive than, and therefore distinguishable from, the more limited concentration ranges disclosed in Wertheim (claimed range of “at least 35%” not supported by disclosure of 25% to 60% range disclosed in priority application). In short, we determine that a person of ordinary skill in the art – a medical doctor with experience treating CRPS – would have recognized that the “inventor invented what is claimed” and did not overreach in claiming “at least 10% zoledronic acid” in an orally administered dosage form for treating CRPS. See University of Rochester, 358 F.3d at 928 (Fed. Cir. 2004).” slip op. at 21

      “Unocal or Wertheim where the specification clearly allowed persons of ordinary skill in the art to recognize the claimed invention despite the absence of literal support. In Unocal, the original disclosure explicitly described the effects of altering the variables, explicitly described the claimed endpoints as preferred, or explicitly recited them in an original claim. Moreover, persuasive expert testimony was offered to support the finding that the specification reasonably conveyed to one skilled in the relevant art that the inventor possessed the later claimed invention. Unocal, 208 F.3d at 993, 998–99. In Wertheim, the CCPA held that the specification supported the claimed range of 35–60% where the specification described the range of 25–60% along with specific embodiments of 36% and 50%. 541 F.2d at 264–65. In this case, the ’239 patent specification does not clearly allow persons of ordinary skill in the art to recognize the “about 80 mg” endpoint as part of invention described in the ’239 patent. There is no disclosure of “about 80 mg” as a preferred endpoint, no disclosure of a specific embodiment including a dose of 80 mg, nor any other description suggesting the importance or criticality of the “about 80 mg” endpoint.” slip op. at 16

      “Dr. Baughman describes the ordinarily skilled artisan physician as an M.D. with at least three years of experience treating RA patients, including with one or more anti-TNFα biologic agents. Ex. 1006 ¶ 15; see Pet. 26; Ex. 1007 ¶ 12 (Dr. O’Dell agreeing with Dr. Baughman’s definition of the skilled physician). Dr. Baughman describes the ordinarily skilled artisan pharmacokineticist as having a Ph.D. in pharmacokinetics or a related field, and at least three years of experience with the pharmacokinetics and pharmacodynamics of biologic agents, either in industry or academia. Ex. 1006 ¶ 15; see Pet. 26–27. Patent Owner’s experts Dr. Gibofsky and Dr. Vinks apply Petitioner’s and Dr. Baughman’s description of the ordinary artisan. Ex. 2065 ¶¶ 53–54; Ex. 2069 ¶¶ 101–103.

      “Owner asserts that “[a]s of June 2001, a treating physician who satisfied the definition of a POSA[4] would have understood the claims to require meaningful therapeutic efficacy.” Resp. at 61 (citing Ex. 2065 ¶¶ 20, 92– 93). As support, Patent Owner points to the ’987 patent specification’s disclosure that “administration of D2E7 produces a meaningful improvement in a variety of clinical outcome measures” such as ACR20, ACR50, and SJC.5 Id. at 62. Patent Owner also contends that the specification of the ’987 patent provides “clinically meaningful outcome parameters” for the treatment of RA. Id. (citing Ex. 2065, ¶¶ 92–93). Patent Owner, therefore, again asserts that we should construe the phrase to mean that the treatment has “meaningful therapeutic efficiency.” We again decline to interpret the claim in this manner. Such a construction would add much uncertainty to the 4 We understand POSA to be used as shorthand for a Person of Ordinary Skill in the Art. 5 ACR is shorthand for the American College of Rheumatology improvement criteria. SJC stands for swollen joint count. Ex. 1001, 28:23;30:22. claim.

      “Petitioner does not carry its burden to show that a person of ordinary skill in the art would have been so motivated. As explained above, in the Petition Petitioner asserts that the ordinary artisan would have doubled van de Putte’s 20 mg dose to 40 mg and weekly dosing interval to biweekly based on the single PK parameter of half-life. In support of that assertion, Dr. Baughman testifies that “half-lives are routinely used to develop the appropriate dosing frequency.” Ex. 1006 ¶ 66. Dr. Baughman’s testimony in that regard may be valid, but the record in this case does not include sufficient persuasive evidence from which we can make that determination. That is, neither Petitioner nor Dr. Baughman directs us to a monoclonal antibody drug with a dosing interval that corresponds to its particular half-life, or to other evidence supporting the assertion that skilled artisans routinely use half-lives to develop a dosing schedule. Accordingly, Dr. Baughman’s testimony on those issues is entitled to little or no weight. 37 C.F.R. § 42.65(a).” slip op. at 20

    • Obviousness (§103) › Motivation to combine / reasonable expectation of success › Teaching awayTeaching away not foundDecided for petitioner

      “We see the evidence somewhat differently. A reference teaches away from the claimed invention if it criticizes, discredits, or would have RA, the 40 mg subcutaneous dose also is insufficient, given the lower bioavailability of a drug after subcutaneous administration. Tr. 46:16–21. We address that contention below in discussing Patent Owner’s argument that Kempeni, and the prior art as a whole, teach away from the 0.5 mg/kg dose. See infra §§ II.C.3.b.(2)(ii)–(2)(iii). discouraged a person of ordinary skill in the art from “following the path set out in the reference,” or if a person of ordinary skill “would [have been] led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994); see In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). The mere disclosure of alternative designs, however, does not teach away. In re Mouttet, 686 F.3d 1322, 1333–34 (Fed. Cir. 2012). Kempeni discloses several clinical studies that utilized different dosing protocols. DE003 was one of those clinical studies. In the DE003 study, patients received 0.5 to 10 mg/kg of D2E7 intravenously “every two weeks” until DAS (Disease Activity Score) responses could be rated as “good.” Ex. 1003, 2 (emphasis added). Thus, far from criticizing, discrediting, or discouraging the person of ordinary skill from pursuing a biweekly regimen, as explained above, Kempeni expressly discloses such dosing frequency.11 We agree with Patent Owner that, for some portion of the treatment period, patients were treated only on flare up. Resp. 49; Ex. 1003, 2. That disclosure, however, does not negate Kempeni’s teaching of biweekly dosing. Nor does it fairly teach away from biweekly dosing. We also agree that some patients were “updosed” for “inadequate clinical response.” Resp. 50; Ex. 1003, 2–3. 11 Additional prior art references support the finding regarding Kempeni’s disclosure. For example, one reference describes the DE003 study as a clinical trial in which “D2E7 was given in doses of 0.5–10 mg/kg [intravenously] over 3–5 minutes every two weeks over a time period of now 1½ years.” Ex. 2114, 4. We find that such disclosure represents, at most, an alternative dosing schedule to the biweekly dosing Kempeni discloses, with patient variability accommodated. In any event, we find that persons of ordinary skill were not led in a direction divergent from that taken by Patent Owner. To the contrary, evidence in the record demonstrates that skilled artisans conducted studies dosing D2E7 subcutaneously in fixed doses, and on a biweekly schedule. Ex. 1004, 1 (disclosing that D2E7 was administered subcutaneously in fixed doses of 20, 40, and 80 mg); Ex. 1005, 3 (describing the DE010 study, in which patients initially were treated with 1 mg/kg D2E7 intravenously, 1 mg/kg D2E7 subcutaneously, or placebo, but thereafter received subcutaneous injections of 1 mg/kg D2E7 biweekly in the open label portion of the study).” slip op. at 24

      “invention if it recites essential structure or steps, or if it is ‘necessary to give life, meaning, and vitality’ to the claim.” Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quoting Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305 (Fed. Cir. 1999)). On the other hand, “a preamble is not limiting ‘where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.’” Id. (quoting Rowe v. Dror, 112 F.3d 473, 478 (Fed. Cir. 1997)). Here, the steps of the method, dosage amount, timing, route of administration, and active component are all specified in the body of the claim. The phrase “reducing the signs and symptoms of rheumatoid arthritis,” therefore, merely recites an intended use. See Boehringer Ingelheim Vetmedica, Inc. v. Schering-Plough Corp., 320 F.3d 1339, 1345 (Fed. Cir. 2003) (statements of intended use typically do not limit the scope of a claim because they “usually do no more than define a context in which the invention operates”). Stated another way, the claims do not expressly recite any particular level of efficacy, meaningful or otherwise. Rather, the claims require administering the antibody in a particular dosage amount, by a particular route, at a particular interval—to a patient with moderately to severely active rheumatoid arthritis.” slip op. at 8

      “Patent Owner does not challenge Petitioner’s showing that the prior art discloses each element of claims 1–4. See generally PO Resp. Based on the full trial record, we determine that van de Putte and Kempeni collectively disclose each limitation of the challenged claims. That is, we agree with Petitioner that van de Putte discloses all of the elements of claims 1–4, with the exceptions of biweekly dosing, and administering the antibody in combination with methotrexate. As explained above, van de Putte discloses a study in which RA patients received weekly doses of 20, 40, or 80 mg of D2E7, or placebo, via subcutaneous self-administration over the course of three months. Ex. 1004, 1. D2E7, therefore, was administered in a pharmaceutically acceptable composition, in unit dosage form. Id. Further, D2E7 is a known recombinant human anti-TNFα antibody having the six CDRs and heavy chain constant region required by claims 1–4, and the amino acid sequences for the variable light and variable heavy chain regions required by claims 2 and 4. Ex. 1001, 3:40–42 (explaining that D2E7 is “described in U.S. Pat. No. 6,090,382, incorporated in its entirety herein by reference”); see Ex. 1008, 2:59–67. Petitioner also shows, by a preponderance of the evidence, that Kempeni accounts for the differences between van de Putte and the recited biweekly dosing frequency required by all of the challenged claims, as well as administering the antibody with methotrexate. Specifically, Kempeni describes a study in which patients received D2E7 via intravenous injection every two weeks for at least 6 months (i.e., 24 weeks), and also teaches that “D2E7 is safe and effective . . . in combination with methotrexate when administered by single and multiple intravenous and subcutaneous injections.” Ex. 1003, 2, 3.” slip op. at 15

      “As we explained in the Institution Decision, claims 1 and 5 do not recite any particular level of efficacy. Rather, they require administering the antibody for a time sufficient to treat RA. Inst. Dec. 9. Consistent with the claims, the specification uses the word “treat” in its customary and ordinary way. For example, the specification describes administering the antibody for therapeutic purposes to alleviate the symptoms and/or progression of the disorder. Ex. 1001, 24:25–60. The portions of the specification on which Patent Owner relies do not persuade us otherwise. The specification explains that the data in Figures 1B and 2–4 “indicate that subcutaneous, biweekly D2E7 treatment combined with methotrexate was significantly better than placebo in reducing the signs and symptoms of RA,” and that all of the doses “were statistically significantly more effective than placebo.” Ex. 1001, 30:25–30.

      “In the absence of analysis of these subsequent references, we conclude that Par has not established that the prior art cited in its challenge adequately represents the state of the art at the time of the invention. Moreover, we note that Horizon points out that Shiple, relied on by Par for its teaching that normal subjects and UCD patients fed PAA experience suppressed urea production (Pet. 17 (citing Ex. 1017, 620, 623; Ex. 1002 ¶ 4), additionally discloses that about 95% of a 10 g dose of phenylacetic acid was excreted as phenylacetyl glutamine in a 24-hour urine sample. Corr. PO Resp. 32 (citing Ex. 1017, 623, Table II). Consequently, we determine that Par has not established by a preponderance of the evidence that one of ordinary skill in the art would have had a reason to calculate the dose of PBA or HPN-100 for a UCD patient based on a mean conversion rate of about 60% (even if we accept that about 60% encompasses a mean conversion rate of 53–67%, as Par argues), given the apparent correspondence between Brusilow ’91’s observation of an 80% to 90% conversion rate, and the similar stated observations in Exhibits 2027 and 2025 (95% and 80–100 %, 29 respectively)—not to mention Shiple’s disclosure of a 95% conversion rate for a 10 g dose of PAA. Again, Petitioner bears the burden of proving unpatentability of the challenged claims in an inter partes review, and that burden never shifts to Patent Owner.

As for the parties’ diametrically opposed views on whether Dr. Brusilow preselected all three doses administered to the patient, or adjusted the dose in Period III to account for the 90% conversion observed in Period II (see Ex. 1012, Table 1), we find we need not resolve the controversy, because, even if we accept that the dose in Period III was adjusted based on the results in Period II, it would not change our ultimate disposition of the case.” slip op. at 27

Moreover, we note that Horizon points out that Shiple, relied on by Par for its teaching that normal subjects and UCD patients fed PAA experience suppressed urea production (Pet. 17 (citing Ex. 1017, 620, 623; Ex. 1002 ¶ 4), additionally discloses that about 95% of a 10 g dose of phenylacetic acid was excreted as phenylacetyl glutamine in a 24-hour urine sample. Corr. PO Resp. 32 (citing Ex. 1017, 623, Table II). Consequently, we determine that Par has not established by a preponderance of the evidence that one of ordinary skill in the art would have had a reason to calculate the dose of PBA or HPN-100 for a UCD patient based on a mean conversion rate of about 60% (even if we accept that about 60% encompasses a mean conversion rate of 53–67%, as Par argues), given the apparent correspondence between Brusilow ’91’s observation of an 80% to 90% conversion rate, and the similar stated observations in Exhibits 2027 and 2025 (95% and 80–100 %, 29 respectively)—not to mention Shiple’s disclosure of a 95% conversion rate for a 10 g dose of PAA. Again, Petitioner bears the burden of proving unpatentability of the challenged claims in an inter partes review, and that burden never shifts to Patent Owner. Obviousness is resolved based on underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) objective evidence of nonobviousness, i.e., secondary considerations. See Graham v. John Deere Co., 383 U.S. 1, 17– 18 (1966). It is not enough to address only those teachings that support the challenge, when there is evidence of record on its face at odds with the underlying premise of the challenge. See e.g., Corr. PO Resp. 5, 15, 22, 32, 49 (discussing Exs. 2025, 2027, 1017).” slip op. at 29

      “Horizon contends that Par’s definition “does not require . . . any experience treating patients with urea cycle disorders or other nitrogen retention disorders,” but “simply requires ‘specialized training in the diagnosis or treatment of inherited metabolic disorders, such as UCD and other nitrogen retention disorders.’” Id. Horizon contends because “the challenged claims specifically relate to methods of treating UCD patients,” one of ordinary skill in the art should have experience treating UCD patients. Id. Horizon’s point is well taken—that is, we agree that one of ordinary skill in the art should have experience treating, as well as diagnosing, UCD patients. In any case, our ultimate disposition of this case would not change under either Par’s or Horizon’s definition.” slip op. at 9

Dr. Sondheimer testifies that he has been involved in several research studies involving the treatment of urea cycle defects and has co-authored several publications about the use of ammonia-scavenging medications.

      “encompassing a range of mean conversion between 53–67%.” Pet. 10–12. Horizon did not address this issue in its Preliminary Response, and we determined it was not necessary to construe the term for purposes of institution. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (“[C]laim terms need only be construed ‘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)). In its Corrected Patent Owner Response, Horizon contends that “the claim term ‘about 60%’ has its plain and ordinary meaning and would be understood by a [person of ordinary skill in the art] to encompass 67%” (Corr. PO Resp. 27), but nothing in the claims, specification or prosecution history of the ’012 patent supports Par’s “assertion that ‘about 60%’ should be construed to encompass 53%” (id.). Nevertheless, we again determine that it is not necessary to expressly construe the term for purposes of this decision. To the extent Par relies on the term as “encompassing a range of mean conversion between 53–67%,” however, we reject its proposed construction.” slip op. at 11

      “In each instance, the specification of the ’192 patent uses the term “inertia” in the context of a window cover system that maintains the window cover at a desired position. We determine that the construction of “inertia” offered by Petitioner is consistent with the use of the word in the specification, and would be understood by one of ordinary skill in the art to mean: “a property of matter whereby it remains at rest or continues in uniform motion unless acted upon by some outside force.” Pet. 15. Moreover, as inertia is itself an attribute, or property, of matter, we determine that the word “inherent” does not contribute any additional meaning to the term, or change the way it would be understood by one of ordinary skill in the art.” slip op. at 12

      “of Tachikawa’s spring drive for maintaining the position of the cover at different roll-up or roll-down positions.” Pet. Reply 3. In other words, Tachikawa’s spring drive, operating as a constituent element of the window covering system, functions to maintain the window cover at a desired position unless the system is acted on by some outside force. This finding is supported by substantial evidence. Specifically, as noted in the Petition, Tachikawa’s spring 17 constantly generates a torque in the opposite direction and identical to the torque on an operating shaft due to the load of the blinds acting upon the operating shaft, “which has the effect that the force for manipulating the operating shaft in order to perform roll-up and roll-down of the blinds can be a small constant force regardless of the position of the blinds” (Pet. 29; Ex. 1002, 209). Tachikawa teaches that this also has the effect that “the blinds do not fall spontaneously due to the weight of the blinds if roll-up is stopped mid-way, but are rather stopped at that position by the spring torque.” Ex. 1002, 209. We credit the testimony of Petitioner’s witness, Mr. Carlson, that “there are three factors that cause the blinds to ‘stop at the midway position’ (i.e. maintain the position of the cover): 1) the spring torque described above, 2) the inherent inertia necessarily present in all mechanical systems, and 3) the friction that is also inherently present in mechanical systems.” Ex. 1017 ¶ 35.” slip op. at 22

      “conclude that Petitioner has failed to prove by a preponderance of the evidence that the window cover system of claim 26 would have been obvious over Tachikawa and Todd. Petitioner points to elements of both references, maps them to elements of claim 26, and argues that it would have been obvious to modify Tachikawa’s window cover system with a plurality of spring drives “depending on the weight and size of a window cover.” Pet. 31–36. Even if we consider this latter argument to be an adequate reason for combining the elements of the references, Petitioner does not explain how one of ordinary skill in the art would go about combining the elements, or what modifications one of ordinary skill in the art necessarily would have made in order to combine the elements. Nor does Petitioner—in the Petition—point to evidence establishing that modifying Tachikawa to have a plurality of spring drives would have been routine for one of ordinary skill in the art. What is missing from the Petition is explicit, “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d at 988; KSR, 550 U.S. at 418.” slip op. at 24

      “Patent Owner submitted during prosecution of a related application. Tr. 7:4– 17, 24:6–11. Nevertheless, we agree with Patent Owner that § 42.61(b) “does not obviate the requirement of an affidavit attesting to the accuracy of a foreign document under § 42.63(b).” Paper 45 (Reply to Petitioner’s Opposition to the Motion to Exclude Evidence), 2. Considering the totality of the circumstances, we concluded, as discussed during the oral hearing, that it would be appropriate, in this instance, to waive our rules to the extent we would allow Petitioner, within five days from the date of the oral argument, “to submit an affidavit attesting to the accuracy of the translation that was previously submitted” (Tr. 8:2–3), with the proviso that the affidavit “meet the requirement[s] of our rules,” specifically “[42 C.F.R. §§] 42.63, 42.2, and also 1.68” (id. at 8:2–5).
