§103
CTFR 18/306,752 CTFR 96924 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Response to Arguments 07-37 AIA Applicant's arguments filed 05/13/2026 have been fully considered but they are not persuasive. The applicant argues on page 7, “ Szela discloses that the number of reference control signals depends on ambient temperature T, but not that charging and discharging of the of the measuring or reference capacitor is controlled based on the ambient temperature T.” The examiner respectfully disagrees. Szela discloses electric charges collected on the measuring capacitor during its charging, electric charges collected on the reference capacitor during its charging with a pulse control signal (include the ambient temperature), power-supply voltage to the control unit that is a source of the current for charging the measuring and reference capacitors, the control-system preset voltage to which the measuring capacitor should discharge itself during counting of the reference control signals and the ambient temperature of said measuring capacitor and said reference capacitor , said signal being sent from said control system as necessary for charging of said measuring capacitor (paragraph [0008]). The above-cited paragraph shows that the capacitor is charged and discharged according to the control signal sent by the control unit, which also includes the parameters like the ambient temperature around the capacitor. The applicant arguments are not persuasive; thus, THIS ACTION IS MADE FINAL . Claim Rejections - 35 USC § 103 07-06 AIA 15-10-15 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 07-20-aia AIA The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains.
