Office Action

§101 §DP
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 Status This Office action is in response to the Divisional filed 4/23/2025. Claims 1-6 are currently pending. 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 1-6 are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1-6 of prior U.S. Patent No. 11,498,738. This is a statutory double patenting rejection. Note that although this application was filed as a Divisional, there was no restriction requirement in the parent application. Claim Objections Claims 2-6 are objected to because of the following informalities: the preamble of each claim reads “The liner of” when it should read “The overpack assembly of.” Appropriate correction is required. Claim 2 is objected to because of the following informality: the claim reads “the liner seam and each side seam are a weld seam” when it should read “the liner seam and each side seam is a weld seam.” Appropriate correction is required. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to THOMAS M WITTENSCHLAEGER whose telephone number is (571)272-7012.
