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 (i.e., changing from AIA to pre-AIA ) 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. 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. 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. Claims 4 and 5 are rejected under 35 U.S.C. 103 as being unpatentable over Abraham (WO 2021/123850 A2) in view of McKinnon et al. (USP No. 6,227,668), hereinafter “McKinnon”. Regarding claim 4, Abraham discloses the claimed invention, but does not specify configured to successively reduce or increase the saturation of successively displayed items or to reduce or increase the saturation of the one or more items with time. In the same field of endeavor, McKinnon discloses configured to successively reduce or increase the saturation of successively displayed items or to reduce or increase the saturation of the one or more items with time (Col. 5, Lines 4-37). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the testing system of Abraham with configured to successively reduce or increase the saturation of successively displayed items or to reduce or increase the saturation of the one or more items with time of McKinnon for the purpose of providing a visual testing system having greater sensitivity for the early detection of eye disorders (Col. 1, Lines 14-16, Col. 2, Lines 51-54). Regarding claim 5, Abraham and McKinnon teach the testing system of claim 4, McKinnon further discloses configured to switch or alternate between increasing and decreasing the saturation of successively displayed items or to switch or alternate between increasing and decreasing the saturation of the one or more items with time (Col. 5, Lines 4-37).It would have been obvious to one of ordinary skill to provide the testing system of Abraham with the teachings of McKinnon for at least the same reasons as those set forth above with respect to claim 4. Claims 12 and 14-17 are rejected under 35 U.S.C. 103 as being unpatentable over Abraham (WO 2021/123850 A2) in view of Abou Shousha et al. (USP No. 11,659,988), hereinafter “Abou Shousha”. Regarding claim 12, Abraham discloses the claimed invention, but does not specify wherein the visual display system comprises a headset display.
