“The definition of a POSA that best incorporates both experience with drug-drug interaction and experience treating patients is Petitioner’s proposed multidisciplinary team. Patent Owner does not object to defining the POSA as part of a multidisciplinary team, so long as that team includes a person with experience treating Cushing’s syndrome, which, as discussed above, is appropriate.

“In addition, when considering the recited methods of treatment (or controlling hyperglycemia) in a patient in the context of the specification, we interpret the recited methods to require administration of drugs in a manner that is safe for a patient. The summary section in the specification of the ’214 patent, for example, states that: concomitant administration of a CYP3A inhibitor such as ketoconazole and a GRM such as mifepristone is believed to be safe for the subject, and to provide the therapeutic benefits of both drugs to the subject, and may allow the reduction in the amount of a GRM, or of a CYP3A inhibitor, administered to the subject; such reduction may reduce the risk of toxic effects of the CYP3A inhibitor concomitantly administered with the GRM. Ex. 1001, 3:50–58 (emphasis added); see id. at 4:4–21.

“Our regulations require the Petition to identify “[h]ow the challenged claim is to be construed” and “[h]ow the construed claim is unpatentable.” 37 C.F.R. § 42.104(b)(3),(4). A reply is not an opportunity to start anew, to fill in gaps or to remedy omissions in a petition. See SAS Inst., Inc. v. Iancu, 138 S.

Even if we were to consider Petitioner’s new argument regarding claim construction, we would not find it persuasive because Petitioner’s obviousness rationale incorporates an expectation of safety.

“reconsider the issue of our construction of “bleach powder.” The parties agree that the specification of the ’954 patent does not contain an express definition of “bleach powder,” so we are required to give the term its “ordinary and customary meaning, as would be understood by one of ordinary skill in the art in the context of the entire disclosure.” Translogic, 504 F.3d at 1257; see Pet. 27–28 (arguing that, “[a]bsent any . . . clear intent, the BRI must be consistent with the interpretation that those skilled in the art would reach,” then offering no particular construction of “bleach powder”); Prelim. Resp. 29–30 (“A person of ordinary skill in the art would have understood that bleach powder combines persulfates with alkalinizing compounds . . . in a fine dry particulate form.” (citing only sources outside the ’954 patent)). In arguments that we may consider, the parties draw our attention to six sources of evidence about the ordinary understanding in the art of “bleach powder.” Req. 2–5 (citing Ex. 1039, 48:9–49:9); Prelim. Resp. 29– 30 (citing Ex. 1002, 15:45–65; Ex. 1011, 17; Ex. 2005, 6; Ex. 2007, 3; Ex. 2012 ¶¶ 34–36). There is evidence that supports Patent Owner’s view that the ordinary meaning of “bleach powder” is a powder that contains an alkalizing agent in addition to persulfates, as opposed to merely a persulfate powder. A textbook called “Hair Preparations” by Thomas Clausen and others states that, at least in paste bleaches, “a bleach powder” is used that “consists of a peroxodisulfate, an alkalinizing agent,” and other ingredients. Ex. 1011, 17. In the context of cream and gel bleaches, this reference teaches that “[p]eroxosulfate . . . can be added as a bleaching powder” but is silent about whether the “bleaching powder” contains any additional ingredients. Id. In a book chapter on “Hair Coloring” by Keith C. Brown, a “bleach booster” powder is discussed that “is usually a mixture of ammonium and potassium persulfates” and that has “metasilicates mixed in with the persulfates” to provide “[a]lkaline pH.” Ex. 2005, 6. Against this evidence is the testimony of Dr. Borish that “powder lighteners” or “bleach powders” include “persulfate salts.” Ex. 1039, 48:9–49:9. But Dr. Borish does not state affirmatively that the persulfate salt is all that is required for a powder to be a bleach powder, only that a persulfate salt is a necessary component of a bleach powder. Id. Accordingly, his testimony does not outweigh the evidence that, to a person of ordinary skill in the art, a bleach powder contains both a persulfate salt and an alkalizing agent. We are not persuaded, therefore, that we abused our discretion by construing “bleach powder” to require both of those components.” slip op. at 6

“support patentability.” Id. Paragraph 109 of Dr. Thirman’s Declaration is nearly identical to the above passage from the Petition. Following the summary of those prior art teachings, Dr. Thirman asserts “[t]hus, the alleged unexpected properties would have been expected” (Ex. 1002 ¶ 110), but provides no further evidentiary support for the proposition that the results obtained by treating relapsed and/or refractory MCL with lenalidomide would have been expected. Again, during prosecution, the Examiner maintained that the combined prior art (Zeldis, Damaj, Wilson, and Kaufmann) would have given one of ordinary skill in the art a reason to use lenalidomide to treat patients with relapsed and/or refractory mantle cell lymphoma, but concluded that the evidence of obviousness was outweighed by Applicant’s evidence of unexpected results—namely, a 28% overall response rate in patients with relapsed and/or refractory mantle cell lymphoma. Although Drach—given its particular focus on treating mantle cell lymphoma—is stronger evidence than Damaj, Wilson, and Kaufmann that one of ordinary skill in the art would have had a reason to treat MCL patients with lenalidomide, Drach is no more informative as to expected results than the references the Examiner relied on in making out a prima facie case of obviousness, i.e., Damaj, Wilson, and Kaufmann. Essentially, Petitioner and Dr. Thirman disagree with the Examiner’s conclusion that, on balance, the subject matter of the challenged claims would not have been obvious, in light of the level of response in patients 25 with relapsed and/or refractory MCL (as described in Dr. Zhang’s Declaration and the underlying Goy reference), despite one of ordinary skill in the art having had a reason to administer lenalidomide to treat MCL.” slip op. at 25

In addition to the ’859 publication, Petitioner relies on Blau and Simell for the teaching to collect blood from UCD patients after a fast in order to measure plasma ammonia levels. Ex. 1006 at 273 (Table 11.9); Ex. 1005 at 1118; see Pet. 25–26 (citing Ex. 1002 ¶¶ 58, 59); see also id. 1002 ¶ 46, n.2 (citing Ex. 1015 at S11). Anticipating Patent Owner’s argument that Blau relates to diagnosis not treatment of UCDs, Petitioner also cites to Exhibits 1010 and 1015 as evidence that it was generally recommended to measure plasma ammonia after a fast. See Pet. 16, n.2. Exhibit 1010 is a “Lab Update” about measurement in ammonia in blood, and Exhibit 1015 is a publication entitled “Measurement of ammonia in blood.” Both state that most methods recommend collecting a sample from patients who have fasted for at least 6 hours. See Ex. 1010, 4; Ex. 1015, 1. From this evidence, we agree with Petitioner that those of skill in the art would have known that measuring fasting serum ammonia levels, as taught in at least Simell and Blau, was known to be useful with the methods taught in the ’859 publication. In regard to Ground 2, which challenges claim 3 and the claims that depend on it, Petitioner cites Brusilow ’84 for its teaching of measuring a patient’s fasting plasma ammonia level when he or she is admitted, presumably to a hospital, and, in response to elevated levels, treating with the nitrogen scavenging drugs sodium benzoate and phenylacetate.

“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.

“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

“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

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.

“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.

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

“We are not persuaded by Patent Owner’s argument.

We are persuaded by the weight of the evidence that it was understood by a person of ordinary skill in the art that rubber stoppers generally have issues with friction during manufacturing, which is commonly cured by adding silicone oil to the stoppers. See, e.g., Ex. 1004, S4 (“Machinability is greatly improved through the use of lubricated packaging components. Siliconization of rubber products reduces the friction present between the rubber closure and with silicone oil, [which] reduces considerably the inherent tackiness in many rubber formulations.
