Office Action

§101 §103
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 . Drawings The drawings are objected to because figure 1 boxes 3,1, 4 need to be labelled descriptively with text , Fig 2 boxes 8,9,1 need to be labelled descriptively with text . Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-20 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claims recite routine data gathering such as determine , supply, generate , compensating . There is nothing else being done to the motor . The judicial exception is not integrated into a practical application. Additional elements that are not abstract , digital to analog converter , processor and memory are generic and are not adding significantly more than abstract idea. Additional elements do not integrate abstract idea into practical application because it does not impose any meaningful limits on practicing abstract idea. Claim Rejections - 35 USC § 103 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. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 16 is rejected under 35 U.S.C. 103 as being unpatentable over 2002/033686 cited by Applicant in view of JP2011030352 . 2002/033686 discloses motor control unit (2) for controlling operation of motor ( 5) having stator and rotor, motor control unit comprising at least one processor and memory device , the at least pone processor being configured to determine a type of motor , see abstract and paragraph 20 . 2002/033686 lacks disclosing first gain for compensating stator resistance and second gain for compensating stator inductance of motor . JP2011030352 discloses resistance gain and inductance gain , see fig 2 #33,#34. It would have been obvious to one of ordinary skill in the art before the effective filing date of claimed invention to combine motor control of 2002/033686 with first and second gain of JP2011030352 for improved control. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. WO2018069865 discloses flux estimator and second gain .
