Office Action

§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 . Response to Amendment The Amendments filed 6/19/25 and 9/3/25 are not entered. The Amendment filed 11/4/25 has been entered. Response to Arguments Applicant’s arguments with respect to the amended claims filed 6/19/25 have been considered as follows. 35 USC 102/103 Rejections of the claims: Applicant’s arguments are moot in view of the new ground rejections. To the extent it may apply, Applicant appears to argue scaling of an optical lens assembly is not obvious for one of ordinary skill in the art. Examiner respectfully disagrees and points out, the optical lens assemblies in the prior arts cited in the office action dated 4/4/25 are in the domain of geometric optics. And it is well-known in the art the image and the aberrations will scale proportionally according to the scaling factor of the optical lens assembly. Further it is well-known scaling up an optical lens assembly will have better diffraction effects but take more space, and scaling down the optical lens assembly will have worse diffraction effects but take less space. One of ordinary skill in the art will have motivation to scaling down the assembly for the purposes of having smaller image size which has advantage of compact size. For the obviousness to choose an IR band-pass filter as the filter, it does not involve any remarkable change in ray tracing process and will have little effects if any on the image quality. Therefore Examiner maintains some rejections, which have been modified as necessary due to the amendments to the claims. 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 of this title, 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) 1,3-4,6,8-14,16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Bone (US 20180372996, of record).
