    “Petitioner may well be correct that preferring a non-anticholinergic does not necessarily exclude administering “another oral and/or topical therapy for reduction of sweating,” as required by challenged claim 4. Petitioner, however, does not point to any credible evidence or otherwise explain why an ordinary artisan would have chosen another therapy to reduce sweating to be administered in combination with glycopyrrolate. Without some articulated reasoning with rational underpinning as to why an ordinary artisan would have added a second therapeutic for reducing sweating to the transdermal patch of Bodor, which uses the anticholinergic to eliminate the formation of an aqueous layer between the delivery system and the skin to enhance the penetration of the transdermal drug being delivered, Petitioner has not met its burden of demonstrating that claim 4 20 would have been obvious over the combination of Bobrove and Bodor.

    “Bobrove specifically teaches applying a “roll on” glycopyrrolate solution. Ex. 1008, 6:26–27, 6:36–37. It, however, also generally teaches that glycopyrrolate is administered topically. Id. at 4:1. Thus, one of ordinary skill in the art would have had a reason to look for other means to apply glycopyrrolate. As Dr. Guy testifies, “[t]here are a limited number of ways to topically deliver a drug to a patient’s skin.” Ex. 1003 ¶ 16. In addition, Bobrove suggests to avoid the eyes, nose, and mouth during the topical administration. Ex. 1008, 5:37–39. Given these considerations, Bodor provides an effective alternative: a cotton cloth to absorb the drug and rub it on the skin.

Thus, we conclude Petitioner has shown, by a preponderance of the evidence, that an ordinary artisan would have had a reason to combine the teachings of Bobrove and Bodor.

Thus, we credit Dr. Staples’s testimony regarding the use of trial-and-error optimization because it appears that this was a known approach for formulating proteins. We do not agree that because the approach was known, it was necessarily expected to be successful. Petitioner cites to the statement in Carpenter that the authors were “quite confident” the generalized high throughput formulation procedure they describe “can be coupled successfully with high throughput screening strategies of protein drugs and facilitate drug development within the inherent time and resource constraints of the pharmaceutical industry.” Ex. 1004, 195. We note that, although in isolation Carpenter’s proclamation of being “quite confident” appears to demonstrate a reasonable expectation of success, when considered in context it refers to a general trend in the industry, not to the ability to formulate specific proteins. The full statement does not indicate that there was confidence that any particular drug could be successfully formulated as a liquid. Thus, this evidence is not persuasive.” slip op. at 7

    “parties, we determine, on balance, that Petitioner has not established sufficiently that an ordinary artisan would have had a reasonable expectation of success in formulating CTLA4Ig as a stable liquid formulation as recited in the challenged claims. Specifically, in the challenge to Patent Owner’s claims, Petitioner relies on Carpenter to show that an ordinarily skilled artisan would have known how to prepare a stable liquid formulation of CTLA4Ig for subcutaneous administration. Pet. 33–40. The statements in Carpenter are the most significant evidence of whether there would have been an expectation of success in achieving the claimed formulation. But Carpenter expressly states that “[i]t [could] be assumed that most proteins will not exhibit sufficient stability in aqueous solution to allow a liquid formulation to be developed.” Ex. 1004, 188; PO Resp. 16. Carpenter also states that although a stable liquid formulation is desirable, “for most proteins maintaining physical and chemical stabilities in aqueous solution for an extended period of time is extremely difficult.” Ex. 1004, 184. These statements indicate that there would not have been a reasonable expectation of success in achieving the claimed formulations. Dr. Staples’s testimony about routine trial-and-error optimization does not overcome these statements. Petitioner’s citation to Paborji (Ex. 1016) does not persuade us otherwise. Even though Paborji states that CTLA4Ig in phosphate buffer is “relatively stable,” without testimony to explain how this would be interpreted by a skilled artisan, the strong doubt about success expressed in Carpenter is not overcome.” slip op. at 13

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.

  • BurdenFwd all claims patentableNot shown unpatentable

    “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. 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

  • ExcludeMotion to exclude, deniedDenied

    “Petitioners argue that Patent Owner’s Exhibits 2022 and 2024 should be excluded because they are not prior art to the ’215 patent. Paper 25, 1–2. Even considering Exhibits 2022 and 2024, we are still persuaded that a preponderance of the evidence shows claims of the ’215 are unpatentable. Accordingly, Petitioners’ motion is dismissed as moot. Petitioners also argue that Patent Owner relies on attorney argument to rebut Petitioners’ challenges, effectively providing impermissible expert evidence, which Petitioners seek to exclude. (Paper 25, 2–6.) We dismiss Petitioners’ argument because attorney argument is not evidence. See Meitzner v. Mindick, 549 F.2d 775, 782 (CCPA 1977) (“Argument of counsel cannot take the place of evidence lacking in the record.”). Therefore, Petitioners’ argument is improperly presented in a motion to exclude evidence. Nevertheless, the issue of evidentiary support for Patent Owner’s arguments is addressed above. Patent Owner argues that evidence relied upon by Petitioners should be excluded. Paper 33. Specifically, Patent Owner seeks to exclude certain portions of Dr. Sondheimer’s cross-examination testimony and Exhibits 1031–1033. Patent Owner acknowledges that “[i]n its Reply (Paper 28), Petitioner has not attempted to rely upon the portions of Dr. Sondheimer’s deposition transcript or the documents Patent Owner seeks to exclude.” Paper 33, 2–3. We dismiss Patent Owner’s motion as being moot. Because Patent Owner cannot point to where Petitioners rely on the testimonial evidence, having apparently not relied on it, we have no basis on which to determine whether the evidence is inadmissible and no basis on which to exclude it. Furthermore, because Exhibits 1031–1033 have not been made of record in this proceeding (see Paper 33, 1), they cannot be excluded.” slip op. at 23

  • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languagePlain and ordinary meaningDecided for petitioner

    “We look to the language of the claim itself and to language in the specification to determine the scope of a claim. To limit a claim beyond what its plain language appears to convey, the patentee “may demonstrate an intent to deviate from the ordinary and accustomed meaning of a claim term by including in the specification expressions of manifest exclusion or restriction, representing a clear disavowal of claim scope.” In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1365 (Fed. Cir. 2004) The plain language of independent claims 1–3 recites only the steps of “measuring,” “comparing,” and “administering.” The claims do not include a “targeting” step or steps such as repeated measuring, comparing, and administering, until the fasting blood ammonia level is less than half the upper limit of normal. See Pet. Reply 5–6. Although Patent Owner cites to evidence of the background of the invention, we have not been directed to evidence within the specification of the ’215 patent that clearly limits the claimed methods from being applied at any blood ammonia level greater than half the upper limit of normal. In addition, Patent Owner does not direct us to testimony or other evidence indicating that those skilled in the art would have considered the language of the claims to require “targeting” a certain blood ammonia level or to specify administering drug dosages only when the blood ammonia level is at about that targeted level. On the contrary, the plain terms of the claims contain no such limitations and are broad enough to embrace the administration of drug at higher blood ammonia levels. Accordingly, we conclude that the correct interpretation of Patent Owner’s claims is a method of measuring a fasting blood ammonia level, comparing this level to the upper limit of normal, and administering drug when the level is any level greater than half the upper limit of normal for blood ammonia level.” slip op. at 14

    “method of providing pharmaceutically acceptable nitric oxide gas requires providing information to the medical provider to safely administer the nitric oxide gas,” thus “confirm[ing] that the ‘providing . . . information’ step is functionally related to the steps in the claimed method.” PO Resp. 31–33. As an initial matter, whether the claims should be interpreted as requiring such a functional relationship is a legal conclusion. See PO Resp. 13. Patent Owner’s conclusion regarding functional relationship between claim terms is based, at least in part, on an overly-limited reading of “pharmaceutically acceptable nitric oxide gas,” as discussed above. See PO Resp. 27. Further, we do not read the transcript testimony relied on by Patent Owner as clearly admitting a functional relationship between the steps of “providing pharmaceutically acceptable nitric oxide gas” and the information of (ii). See PO Resp. 31–32 (citing Ex. 2022, 78:15–80:4, 81:11–22, 111:2–17)). To the contrary, Dr. Beghetti appears to have testified that the claim elements are not directly related. Ex. 2022, 86:10– 25. Although Patent Owner points to In re Distefano, 808 F.3d at 848, as evidence that a “printed matter analysis includes ‘factual findings’” (PO Sur Reply 4, n.6), which inform the ultimate legal conclusion, we do not find the evidence as a whole compelling.” slip op. at 19

  • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner

    “The Applicant amended the preamble of the rejected independent claims to recite “[a] method of providing pharmaceutically acceptable nitric oxide gas,” as presently set forth in claims 1 and 7. Id. at 746–747. Subsequent to the amendment, the Examiner withdrew the objection. Id. at 765; see id. at 733 (“If all the priority issues are resolved then it appears that the primary reference in the 103 rejection will no longer be prior art.” (italics omitted)). On pages 19 and 20 of its Response, Patent Owner argues that the preamble is, therefore, limiting in light of Catalina Mktg. International, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002), which holds that “clear reliance on the preamble during prosecution to distinguish the claimed invention from the prior art transforms the preamble into a claim limitation because such reliance indicates the use of the preamble to define, in part, the claimed invention.” Although the prosecution history shows that amendment of the preamble only indirectly distinguished the claims over the prior art by establishing an earlier priority date, we conclude that both the Applicant and the Examiner treated the preamble as a claim limitation. Accordingly, we agree with Patent Owner that the preamble language “pharmaceutically acceptable nitric oxide gas” is limiting.” slip op. at 11
