Office Action

§101
DETAILED ACTION The present application is being examined under the pre-AIA first to invent provisions. 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 1-12 is/are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1-12 of prior U.S. Patent No. 12076626 B2. This is a statutory double patenting rejection. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Kim US 20110300963 A1 – Which shows a golf club head with adjustable head speed and a coil spring. Yashiki US 20120172142 A1 – Which teaches a golf club with a weight on the shaft end.
