Regarding Claim 17, Pichon discloses the optical system assembly according to claim 1, wherein at least one of the plurality of lens slots is configured with a thickness same as that of a thickness of a corresponding lens, amongst the at least two of lenses to avoid any rattling or loose fitting of the at least one lens within the corresponding lens slot (Figure 1, the thicknesses of the lens must match that of the slot). Regarding Claim 18, Pichon discloses the optical system assembly according to claim 1, wherein the at least one spacer spring has at least partly a cylindrical shape and/or has at least one groove, at least one step and/or at least one cut out, running at least partly along an outer surface of the at least one spacer spring (Figure 1 discloses a plurality of grooves/steps/cut outs in the spacer spring 25). Regarding Claim 19, Pichon discloses the optical system assembly according to claim 18, wherein the groove, the step and /or the cut-out is/are formed in a wall comprising the outer surface of the at least one spacer spring, wherein the wall extends in a direction parallel to a longitudinal axis extending from the first opening to the second opening and/or the groove and/or the step is with respect to the longitudinal axis inwardly extending from the wall or is with respect to the longitudinal axis radially outwardly extending from the wall (Figure 1, spacer spring 25).

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 28 is rejected under 35 U.S.C. 103 as being unpatentable over Pichon in view of Masuzawa et al (US Publication No.: US 2019/0101718 A1, “Masuzawa”). Regarding Claim 28, Pichon discloses the optical system assembly according to claim 1. Pichon fails to disclose that the optical system assembly is configured to be used with the camera device of a vehicle. However, Masuzawa discloses a similar optical assembly where the optical system assembly is configured to be used with the camera device of a vehicle (Masuzawa, Paragraph 0050). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the assembly as disclosed by Pichon to be included in a vehicle as disclosed by Masuzawa. One would have been motivated to do so for the purpose of allowing users to observe their environments outside the vehicle (Masuzawa, Paragraph 0050).
