Office Action

§101 §DP
DETAILED ACTION Remark An rce filed on 8/26/25 had been entered in the application. 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 1-11 are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1-16 of prior U.S. Patent No. 9,203,143. This is a statutory double patenting rejection. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to THO GIA PHAN whose telephone number is (571)272-1826. The examiner can normally be reached on M-F (8-430). If attempts to reach the examiner by telephone are unsuccessful, the examiner’s supervisor, Dimary Lopez can be reached on (571) 270-7893.
