ADAMS, ERIC B. GRIMES, and JOHN E. SCHNEIDER, Administrative Patent Judges. SCHNEIDER, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134(a) involving claims to pharmaceutical composition for treating AIDS which have been rejected as obvious and for non-statutory obviousness-type double patenting. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. STATEMENT OF THE CASE Human immunodeficiency virus (HIV) is the agent for causing acquired immunodeficiency syndrome (AIDS). Spec. 1. “The spread of HIV has caused and continues to cause serious health problems throughout 1 Appellant identifies the Real Party in Interest as Janssen Sciences Ireland UC. Appeal Br. 1. Appeal 2017-002082 Application 12/517,665 the world. Consequently, the search for effective pharmaceutical agents to treat HIV infection is of vital importance.” Id. “One class of anti-HIV pharmaceutical agents comprises the non-nucleoside reverse transcriptase inhibitors (NNRTIs).” Id. One problem with at least some NNRTIs is that they are poorly soluble in water and have low bioavailability. Id. The Specification describes a pharmaceutical composition containing an NNRTI which an improved solubility in water and improved bioavailability. Spec. 3. Claims 1, 4, 7, 11, 12, and 14 are on appeal. Claims 1 and 11 are the independent claims and read as follow: 1. A pharmaceutical composition for immediate release comprising a solid dispersion consisting of a compound of formula (I): Bx A < ; J- . Nl! ' A A'\V A XA" X,. -X*' HN, HBf \V X said compound having a degree of crystallinity of about 10% or less, in a water soluble polymer selected from the group consisting of hydroxypropylmethyl cellulose, polyvinyl pyrrolidone, copolyvidone, and vitamin E TGPS; and wherein the weight : weight ratio of the polymer to compound being in the range from 3:1 to 1:1. 2 Appeal 2017-002082 Application 12/517,665 11.

Appellant does not provide separate arguments for claim 7. Further, although claims 11, 12, and 14 have been rejected over Raoof combined with Siepmann, Winston, or Scholler further in view of Reier, Appellant has not offered any specific arguments with respect to these claims, but has addressed these claims along with claim 1. Appeal Br. 5. We interpret Appellant’s argument to be that Reier fails to make up for Appellant’s alleged deficiency in the combination of Raoof with Siepmann, Winston, or Scholler. Therefore, we find that claims 7, 11, 12, and 14 stand or fall with claim 1. The Examiner finds that Raoof teaches Compound I (TMC125-HBr). Final Act. 2. The Examiner finds that Siepmann, Winston and Scholler all teach the addition of HPMC to compound I to improve solubility. Final Act. 3—6. The Examiner concludes that it would have been obvious to one skilled in the art to combine the teachings of Raoof with Siepmann, Winston, or Scholler to produce the claimed invention. Id. 8 Lamoureux et al., US 8,722,696 B2, issued May 13, 2014 (“Lamoureux”). 5 Appeal 2017-002082 Application 12/517,665 Appellant contends that the references do not teach or suggest that TMC125-HBr has a crystallinity of less than 10%. Appeal Br. 6—7. Appellant argues that the references do not teach or suggest the recited weight ratios for TMC125-HBr and HPMC. Id. at 7—8. Appellant also argues that none of the references teach the preparation of a solid dispersion for immediate release. Id. at 8. Principles of Law [T]he examiner bears the initial burden, on review of the prior art or on any other ground, of presenting a prima facie case of unpatentability. If that burden is met, the burden of coming forward with evidence or argument shifts to the applicant. After evidence or argument is submitted by the applicant in response, patentability is determined on the totality of the record, by a preponderance of evidence with due consideration to persuasiveness of argument. In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992). A proper § 103(a) analysis requires “a searching comparison of the claimed invention—including all its limitations—with the teaching of the prior art.” In re Ochiai, 71 F.3d 1565, 1572 (Fed. Cir. 1995). Where ... the claimed and prior art products are identical or substantially identical ... the PTO can require an applicant to prove that the prior art products do not necessarily or inherently possess the characteristics of his claimed product. . . . [The] fairness [of the burden-shifting] is evidenced by the PTO’s inability to manufacture products or to obtain and compare prior art products. In re Best, 562 F.2d 1252, 1255 (CCPA 1977). “[T]he discovery of an optimum value of a variable in a known process is normally obvious.” Exceptions to this rule include (1) the results of optimizing a variable were unexpectedly good and (2) the parameter 6 Appeal 2017-002082 Application 12/517,665 optimized was not recognized in the prior art as one that would affect the results. In re Antonie, 559 F.2d 618, 620 (CCPA 1977). Analysis We adopt the Examiner’s findings of fact, reasoning on scope and content of the prior art, and conclusions set out in the Final Office Action and Answer regarding this rejection. We find the Examiner has established that the claims would have been obvious in view of Raoof combined with Siepmann, Winston, or Scholler. Appellant has not produced evidence showing, or persuasively argued, that the Examiner’s determinations on obviousness are incorrect. Only those arguments made by Appellant in the Briefs have been considered in this Decision. Arguments not presented in the Briefs are waived. See 37 C.F.R. § 41.37(c)(l)(iv) (2015). We have identified claim 1 as representative; therefore, all claims fall with claim 1. We address Appellant’s arguments below. Appellant contends that none of the references teach or suggest that the compound of formula I has a degree of crystallinity of less than 10%. Appeal Br. 6—7. We are unpersuaded. The present Specification teaches that it was known in the art that the degree of crystallinity is inversely proportional to the bioavailability of poorly water soluble pharmaceutical compositions. Spec. 2. Thus, one skilled in the art would have been motivated to use an active agent that is low in crystallinity or amorphous to enhance bioavailability. Moreover, the references teach the same compounds and adjuvants as those found in the claims. Final Act. 2—6. Since the compositions in the references are the same as what is instantly claimed, the burden shifts to Appellant to demonstrate that the prior art 7 Appeal 2017-002082 Application 12/517,665 products do not inherently possess a low crystallinity. Best, 562 F.2d at 1255. Appellant argues that the references do not teach or suggest the claimed weight ratios for the active ingredient and polymer. Appeal Br. 7. Appellant contends that the references do not set forth the general conditions from which one skilled in the art would be expected to derive the optimal conditions. Id. Appellant’s argument is not persuasive. We agree with the Examiner that the references suggest a general condition of a ratio of 1:1 and that it would have been a matter of routine manipulation of parameters to discover the optimum ratios. Ans. 21—22. Appellant has offered no evidence to show that the claimed ratios produced unexpected results or that the ratio of polymer and active ingredient would not be looked to in order to optimize the effectiveness of the composition. Antonie, 559 F.2d at 620. Appellant argues that none of the references teach or suggest a solid dispersion for immediate release. Appeal Br. 8. We are unpersuaded. Scholler specifically teaches a tablet of TMC125 with HPMC. Scholler 1. Siepmann teaches that the surface area of HPMC tablets can be varied to control the release rate. Siepmann 143. We agree with the Examiner that it would have been obvious to one skilled in the art to produce a solid composition containing TMC125 and HPMC and to adjust the surface area of HPMC tablets to produce a composition which yields immediate release of the active agent. Ans. 21—22. 8 Appeal 2017-002082 Application 12/517,665 Conclusion of Law We conclude that claim 1 would have been obvious over Raoof combined with Siepmann, Winston, or Scholler. Claims 7, 11, 12, and 14 have not been argued separately and, therefore, fall with claim 1. 37 C.F.R. § 41.37(c)(l)(iv). Claim 4 Appellant contends that the references do not teach or suggest that one skilled in the art would have selected HPMC 2910 5mPa as the specific HPMC to use in the claimed composition. Appeal Br. 9. Appellant contends that Gilis is limited to teaching which azoles should be used with HPMC 2910 5mPa. Id. We are not persuaded. Gilis teaches that HPMC 2910 5mPa is a commercially available form of HPMC suitable for use in drug compositions containing a lipophilic active agent. Gilis 38-40. Appellant’s Specification acknowledges that TMC125 was a known compound and has low water-solubility (Spec. 1); i.e., it is lipophilic rather than hydrophilic. Gilis also teaches that the addition of HPMC aids in the bioavailability of the lipophilic active ingredient and teaches a weight ratio of drug to polymer of from 1:1 to 1:5. Gilis 40-42. We agree with the Examiner that it would have been obvious to one skilled in the art to use HPMC 2910 5mPa as the polymer in the claimed composition. Ans. 22—23. Conclusion of Law We conclude that a preponderance of evidence supports the Examiner’s conclusion that claim 4 would have been obvious over Raoof combined with Siepmann, Winston, or Scholler further combined with Gilis. 9 Appeal 2017-002082 Application 12/517,665 OBVIOUSNESS-TYPE DOUBLE PATENTING Issue The issue with respect to this rejection is whether a preponderance of the evidence supports the Examiner’s conclusion that claims 1, 4, 7, 11, 12, and 14 are not patentably distinct from claims 1—5 of Lamoureux. The Examiner finds that Lamoureux claims a pharmaceutical composition comprising the same compound as formula I in the instant claims with a surface active agent and a hydrophilic polymer. Final Act. 17. The Examiner finds that the present claims call for the same active ingredient with a hydrophilic polymer such as HPMC. Id. The Examiner concludes that the composition recited in the present claims is not patently distinct from the composition claimed in Lamoureux. Final Act. 17. Appellant contends that the present claims are patently distinct from those of Lamoureux in that Lamoureux does not teach or suggest that the active agent has a degree of crystallinity of less than 10% or the weight ratio recited in the instant claims. Appeal Br. 9—10. Principles of Law The primary inquiry in double patenting cases is therefore whether the claims in the latter [sic, later] patent are more than a “slight variant” from the claims in the earlier patent. . . . Nonetheless, nonstatutory double patenting is sometimes referred to as “obviousness-type” double patenting . . . and “prevents the extension of the term of the original patent via the patenting of an obvious variation.” . . . Eli Lilly & Co. v. Teva Pharms. USA, Inc., 619 F.3d 1329, 1341—42 (Fed. Cir. 2010) (internal citations omitted). 10 Appeal 2017-002082 Application 12/517,665 Analysis We agree with the Examiner that the instant claims represent nothing more than an obvious variant of the claims of Lamoureux. Lamoureux claims the same active agent combined with a hydrophilic polymer such as HPMC. Lamoureux claims 1 and 3. While Lamoureux does not claim a specific range of polymer to active agent weight ratio, nor do the claims specify the percent crystallinity of the active agent, as discussed above, those parameters would have been obvious based on the knowledge of a person of ordinary skill in the art. Thus, the present claims are nothing more than an obvious variant of those in Lamoureux. Conclusion of Law We conclude that a preponderance of the evidence supports the Examiner’s conclusion that the pending claims are not patentably distinct from those of Lamoureux. SUMMARY We affirm the rejections under 35 U.S.C. § 103(a). We affirm the rejection for obviousness-type double patenting. TIME PERIOD LOR RESPONSE No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
