Office Action

§103
DETAILED ACTION This communication is in response to the Applicant filing on 4.10.26. Claims 11-22 are pending and have been examined. 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 . Response to Arguments and Amendments The Applicant has made amendments to the independent claims 11,21 which will be examined below. Previous specification objection respect to title is withdrawn in light of title amendment. With respect to 35 U.S.C 102 and 103 rejections, the Applicant provides arguments to which the Examiner will respond accordingly: Applicant Argument 1: Amended claims 11 and 21 of the instant application require two or more arms integrally formed with or onto the body. In contrast, Domyo teaches a single metal clip (arm) 74 that is not integrally formed with the sensor support (case) 51. Rather Domyo explicitly describes a separate part (arm) 74 that can be subsequently mounted, forming a force-fit connection to the bearing shield 13. Examiner Response 1: Applicant has amended claim 11,21 with new limitations “said arms being integrally formed” which will be prosecuted in below sections. Applicant Argument 2: Furthermore, Domyo does not indicate a desire to space the body 51 away from the bearing shield 13. Rather, the clamp 74 in Domyo is intended to press the sensor support (case) 51 against the bearing shield 13. In other words, the clamp 74 presses the sensor support 51 against the bearing shield 13. Therefore, a spacing by the clamp 74 is neither possible nor intended. Examiner Response 2: Examiner respectfully disagrees . Fig 8 of Domyo discloses a gap between 51 sensor body and 13 bearing shield with contact being made through pointed leg part 61 which is similar to closest Applicant embodiment Fig 12 that Examiner could find wherein contact is being made through 90 between bearing shield 44 and sensor support 66,82. Claim Rejections - 35 USC § 103 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 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. 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. Claims 11,14-15,17-18,21 are rejected under 35 U.S.C. 103 as being unpatentable in view of Domyo (WO2015098056A1 English translation) and Kodera (WO2016103619A1 English translation). Regarding Claim 11, Domyo discloses (Figs 1,8) an electric motor (10) of an ancillary unit (10), the electric motor comprising: a bearing shield (13); a sensor (41,43); and a sensor support (51) made of a plastics material (Page 5, Line 33) and having a body (51) disposed perpendicularly (Fig 1) to a rotor axis (AA), on said body said sensor is held (Page 5, Line 34-35), said sensor support further having at least two arms (Fig 26,74) peripherally attached to said body, said arms at least in part run parallel (Fig 1) to the rotor axis (AA) and are fastened (75) to said bearing shield (13), and said arms (74) configured to space apart (Sp similar to Applicant embodiment Fig 12) said body (majority of 51) as 51 contacts 13 through 61) from said bearing shield but Domyo does not explicitly disclose usage in a motor vehicle and said arms being integrally formed with said body. Domyo further discloses usage in a motor vehicle [Page 3, Line 39 discloses “starter motor” and Line 28 “internal combustion engine” which are well known in the art for usage in motor vehicle]. Kodera discloses (Fig 8) integrally formed (Page 9, Lines 35-37) arm (54) with body (51) (to duplicate another integrally molded arm is well known in the art). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have formed electric motor of Domyo with usage in motor vehicle as is well known in the art in order to function as a starter motor and integrally formed arm as taught by Kodera in order to simplify reduce part count, simplify design and assembly.
