Office Action

§101 §102 §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 . 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 1-7 and 9 is/are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1-3, 8-11, and 12, respectively, of prior U.S. Patent No. 12,036,568. This is a statutory double patenting rejection. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 8 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Apffel et al. (20160172178). Regarding claim 8, Apffel discloses a system for measuring a volume of fluid dispensed by a fluid dispenser, the system comprising: a capture probe (100) for receiving and capturing a dispensed volume of fluid from the fluid dispenser, the dispensed volume of fluid including a calibration standard (analytes; par. 0042); an ionization source (442) for ionizing the captured volume of fluid; and, a mass spectrometer (par. 0088) for measuring a mass of the calibrant contained in the ionized volume of fluid. Allowable Subject Matter Claims 10-11 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
