Office Action

§103 §DOUBLEPATENT
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Priority The instant application is a continuation of US Application 18/098,798 (filed January 19, 2023, now issued as US Patent 12,138,273), which is a continuation of US Application 16/989,304 (filed August 10, 2020, now issued as US Patent 11,559,534), which is a continuation of US Application 16/808,912 (filed March 4, 2020, now issued as US Patent 10,792,292), which is which claims the benefit of an effective US filing date under 35 USC 119(e) from US provisional applications 62/849,259 and 62/814,568, filed May 17, 2019 and March 6, 2019, respectively. Information Disclosure Statement The information disclosure statement dated October 18, 2024 was in compliance with the provisions of 37 CFR 1.97 and 1.98. Accordingly, the IDS document was considered and a signed copy of the 1449 form is attached. Status of Claims Currently, claims 3-25 are pending in the instant application and under consideration herein. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). An obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but an examined application claim is not patentably distinct from the reference claim(s) because the examined claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985). Claims 3-25 are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over Claims 1-34 of US Patent 12,138,273; Claims 1-23 and US Patent 11,559,534; Claims 1-28 of US Patent 10,792,292; and Claims 1-21 of US Patent 11,957,696. Claims 3-25 are provisionally rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over Claims 1-2, 5, 7, 9, 12, 20, 27, 31, 45, 59 and 54-55 of copending US Application 17/635,106; Claims 1-3, 20-21 and 25-37 of copending US Application 19/331,393; Claims 1, 4, 13, 15, 17-18, 22, 24, 29, 31, 33, 38-39, 42-43, 50, 55, 76, 82-83 and 89 of copending US Application 18/689,500; and Claims 98-117 of copending US Application 18/842,725. The conflicting claims are drawn to methods of treating prostate cancer comprising administering abiraterone decanoate. Dependent claims recite, for example, intramuscular injection, the required dosing schedule of once a week to once every three months, and the required dosage of about 50 mg to about 2000 mg of active ingredient. Certain claims of the copending and patent claims recite pharmaceutical compositions, crystalline forms, or emulsions of abiraterone decanoate. With respect to the conflicting claims which are directed to a different statutory class of invention (compositions or compounds rather than methods of use), the Federal Circuit, in Sun v. Lilly, recounts its own decisions in Geneva and Pfizer, In both cases, we found claims of a later patent invalid for obviousness-type double patenting where an earlier patent claimed a compound, disclosing its utility in the specification, and a later patent claimed a method of using the compound for a use described in the specification of the earlier patent. Sun Pharmaceutical Industries Ltd. v. Eli Lilly and Co., 95 USPQ2d 1797 at 1800 (Fed. Cir. 2010). In reaffirming its holding in Geneva and Pfizer, the Court finds that a "claim to a method of using a composition is not patentably distinct from an earlier claim to the identical composition in a patent disclosing the identical use.” (Id. at 1801, quoting Pfizer, 518 F.3d at 1363; Geneva, 349 F.3d at 1385-86. The Court reasserts this notion by stating, [i]t would shock one's sense of justice if an inventor could receive a patent upon a composition of matter, setting out at length in the specification the useful purposes of such composition, . . .and then prevent the public from making any beneficial use of such product by securing patents upon each of the uses to which it may be adapted. Pfizer, 518 F.3d at 1363 n.8 (emphases added); Geneva, 349 F.3d at 1386 (quoting In re Byck, 48 F.2d 665, 666 [9 USPQ 205] (CCPA 1931)). Sun Pharmaceutical Industries Ltd. v. Eli Lilly and Co., 95 USPQ2d 1797 at 1802 (Fed. Cir. 2010). Section 804 IIb of the M.P.E.P. states ...those portions of the specification which provide support for the reference claims may also be examined and considered when addressing the issue of whether a claim in the application defines an obvious variation of an invention claimed in the reference patent or application (as distinguished from an obvious variation of the subject matter disclosed in the reference patent or application). In re Vogel, 422 F.2d 438, 441-42, 164 USPQ 619, 622 (CCPA 1970). The court in Vogel recognized "that it is most difficult, if not meaningless, to try to say what is or is not an obvious variation of a claim," but that one can judge whether or not the invention claimed in an application is an obvious variation of an embodiment disclosed in the patent or application which provides support for the claim. According to the court, one must first "determine how much of the patent disclosure pertains to the invention claimed in the patent" because only "[t]his portion of the specification supports the patent claims and may be considered." The court pointed out that "this use of the disclosure is not in contravention of the cases forbidding its use as prior art, nor is it applying the patent as a reference under 35 U.S.C. 103, since only the disclosure of the invention claimed in the patent may be examined." In AbbVie Inc. v. Kennedy Institute of Rheumatology Trust, 764 F.3d 1366, 112 USPQ2d 1001 (Fed. Cir. 2014), the court explained that it is also proper to look at the disclosed utility in the reference disclosure to determine the overall question of obviousness in a nonstatutory double patenting context. See Pfizer, Inc. v. Teva Pharm. USA, Inc., 518 F.3d 1353, 86 USPQ2d 1001 (Fed. Cir. 2008); Geneva Pharmaceuticals Inc. v. GlaxoSmithKline PLC, 349 F3d 1373, 1385-86, 68 USPQ2d 1865, 1875 (Fed. Cir. 2003). In the instant case, the specification of each conflicting patent or patent application identifies the compound abiraterone decanoate as being useful as a CYP17A1 inhibitor for the treatment of prostate cancer. Since the conflicting patent and applications disclose a utility for the compounds claimed therein which is identical to the methods recited in the instant claims, the conflicting claims anticipate the instantly claimed invention.
