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 .
The double patenting rejections are maintained:
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 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); 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 nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer.
Claims 85, 87-93, 95-97, 99-111 remain rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-46 of U.S. Patent No. 10765743.
Although the claims at issue are not identical, they are not patentably distinct from each other. Specifically, the methods covered in the conflicting claims cover those covered by the rejected claims. Alternatively, the difference between the conflicitng clais and the instant methods is that the conflicting claims do not recite the instant methods with particularity so as to amount to anticipation (See M.P.E.P. § 2131: "[t]he identical invention must be shown in as complete detail as is contained in the ... claim." Richardson v. Suzuki Motor Co., 868 F.2d 1226, 1236, 9 USPQ2d 1913, 1920 (Fed. Cir. 1989). The elements must be arranged as required by the claim, but this is not an ipsissimis verbis test, i.e., identity of terminology is not required. In re Bond, 910 F.2d 831, 15 USPQ2d 1566 (Fed. Cir. 1990).). However, the conflicting claims recite elements of the instant methods with sufficient guidance, particularity, and with a reasonable expectation of success, that the invention would be prima facie obvious to one of ordinary skill (the prior art reference teaches or suggests all the claim limitations with a reasonable expectation of success. See M.P.E.P. § 2143).
Claims 85, 87-93, 95-97, 99-111 remain rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-35 of U.S. Patent No. 10500276.
The conflicting claims may recite conjugates. However, the specification of these patents and applications discloses the utility of the recited xonjugates as covered by the instant methods of using the compounds, see Sun Pharmaceutical Industries, Ltd., v. Eli Lilly and Co. where the district court ruled that the claims of the ‘826 patent were invalid in light of the ‘614 patent which disclosed gemcitabine’s use in cancer treatment, but did not claim it. In making this ruling, the district court relied on the Federal Circuit’s earlier rulings on double patenting of compound claims, mainly Geneva Pharmaceuticals, Inc, v. GlaxoSmithKline PLC, 349 F. 3d 1373 (Fed. Cir. 2003), and Pfizer, Inc. v. Teva Pharmaceuticals USA, Inc., 518 F.3d 1353 (Fed. Cir. 2008). In both of these cases, the Federal Circuit 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. The cases also established that in determining the scope of compound claims for a double patenting rejection one must look to the specification to interpret the utility of the compound.
Claims 85, 87-93, 95-97, 99-111 remain rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-35 of U.S. Application No. 18175894.
The conflicting claims may recite conjugates. However, the specification of these patents and applications discloses the utility of the recited conjugates as covered by the instant methods of using the conjugates, see Sun Pharmaceutical Industries, Ltd., v. Eli Lilly and Co. where the district court ruled that the claims of the ‘826 patent were invalid in light of the ‘614 patent which disclosed gemcitabine’s use in cancer treatment, but did not claim it. In making this ruling, the district court relied on the Federal Circuit’s earlier rulings on double patenting of compound claims, mainly Geneva Pharmaceuticals, Inc, v. GlaxoSmithKline PLC, 349 F. 3d 1373 (Fed. Cir. 2003), and Pfizer, Inc. v. Teva Pharmaceuticals USA, Inc., 518 F.3d 1353 (Fed. Cir. 2008). In both of these cases, the Federal Circuit 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. The cases also established that in determining the scope of compound claims for a double patenting rejection one must look to the specification to interpret the utility of the compound.
Applicant argues that the presently amended claims are directed to methods of treating a distinct subpopulation of patients who have a cancer resistant to a tyrosine kinase inhibitor selected from erlotinib, afatinib, gefitinib, lapatinib, osimertinib, rociletinib, imatinib, sunitinib, crizotinib, midostaurin, and quizartinib, a MEK inhibitor, and/or a chemotherapeutic agent selected from paclitaxel, docetaxel, cisplatin, metformin, doxorubicin, etoposide, and carboplatin. The claimed methods targeting this distinct subpopulation of patients are not anticipated by nor obvious variants of the claims of the reference patents or application, which do not teach or suggest treating a patient population resistant to the recited inhibitors, much less provide the requisite motivation to target patients resistant to these specific inhibitors. Accordingly, Applicant respectfully requests that the rejection be withdrawn.
However, antibody-drug conjugates (ADCs) differ from the recited small molecule therapies primarily because they are targeted and specifically deliver potent cytotoxic payloads to cancer cells, reducing systemic toxicity. While small molecules act generally and freely circulate, ADCs use an antibody to target specific surface antigens, resulting in lower side effects and higher efficacy against specific tumors. In this manner, the those of ordinary skill would have expected that the ADC’s would be effective against cancers that are resistant to the recited small molecules because of this specificity and different mechanism of action. Therefore, using the recited ADCs to treat cancers resistant to the recited cancer therapies would have been prima facie obvious.
Also, the conflicting claims may recite conjugates whereas the rejected claims recite methods. However, the specification of these patents and applications disclose the utility of the recited compounds as covered by the instant methods of using the compounds, as discussed above.
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
