Office Action

§101 §112
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 Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1 – 20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Each of the independent claims 1 and 15 recites components a), b), c) d) (i.e., a + b) or e) (i.e., a + c) which is ambiguous as it is unclear if the claims either a), b), c), d) or e) or if the claims require either d) or e) alone. For the sake of examination, the claims are interpreted as allowing any one of a), b), c) d) or e). Each of the independent claims 1 and 15 recites Hd hydrogen and Hc2 hydrogens which are ambiguous and undefined as the terms can be assigned myriads of arbitrary meanings as desired from person to person practicing the invention. For the sake of examination, the values are understood as representing H NMR characters and values. 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 are provisionally rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1 – 20 of copending Application No. 18/905,801. This is a provisional statutory double patenting rejection since the claims directed to the same invention have not in fact been patented.
