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 Applicant’s arguments, see pages 5-8, filed 05/28/2026, with respect to the rejection(s) of claim(s)1, 3-10 under 35 U.S.C.103 respectively have been fully are not persuasive. Argument: PNG media_image1.png 182 654 media_image1.png Greyscale Kitaji teaches the sensor (241) positioned on a surface of the printed circuit board (24) facing the stator (321) and is separated from the rotor only by air as shown in figures 2 and 4. In summary, the Examiner has taken the broadest and most reasonable interpretation of the claim limitations as written, in light of the specification. Although the specification may contain recitations of intended use, alternative points of view and subjective interpretative differences between the prior art of record and the present invention as premeditated, it is the claims themselves that are given patentable weight only inasmuch as they are constructed. Because the claimed invention has been painted with the broad stroke of petitioning for limitations that encompasses more than is asserted in the Applicant’s claims, the prior art of record continues to fully discloses the Applicant’s inventions as claimed. 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) 1-2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Bohm (DE102014220201) in view of Kitaji et al. (US PG Pub 2015/0381017).
