Office Action

§101
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 . Claim Objections Claims 13 – 20 are objected to because of the following informalities: Regarding claim 13, the claim recites the limitation “The method of claim 12” should have been “The non-transitory computer-readable medium of claim 12”. Regarding claim 14, the claim recites the limitation “The method of claim 12” should have been “The non-transitory computer-readable medium of claim 12”. Regarding claim 15, the claim recites the limitation “The method of claim 12” should have been “The non-transitory computer-readable medium of claim 12”. Regarding claim 16, the claim recites the limitation “The method of claim 12” should have been “The non-transitory computer-readable medium of claim 12”. Regarding claim 17, the claim recites the limitation “The method of claim 12” should have been “The non-transitory computer-readable medium of claim 12”. Regarding claim 18, the claim recites the limitation “The method of claim 12” should have been “The non-transitory computer-readable medium of claim 12”. Regarding claim 19, the claim recites the limitation “The method of claim 12” should have been “The non-transitory computer-readable medium of claim 12”. Regarding claim 20, the claim recites the limitation “The method of claim 12” should have been “The non-transitory computer-readable medium of claim 12”. Appropriate correction is required. Double Patenting A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957). A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. Claims 1 - 20 is/are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1 - 20 of prior U.S. Patent No. 12,323,203. This is a statutory double patenting rejection.
