Patentability shall not be negated by the manner in which the invention was made. 07-20-02-aia AIA 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. 07-21-aia AIA Claim s 23 and 33 are rejected under 35 U.S.C. 103 as being unpatentable over Kim in view of Liao et. al (US 11467633 B2) hereafter referred to as Liao . Regarding claim 23, Kim teaches the electronic device according to claim 22 wherein the synchronization assembly further (cross section shown in Fig 16, expanded view on Fig 8) comprises a third gear (gear disposed on 950 third shaft) and a fourth gear (gear disposed on 960 fourth shaft) the third gear and the fourth gear are engaged with each other(Fig 16), and the third gear and the fourth gear are located on a side of the second conjoined cam that is other that a side of the second conjoined cam that is closest to the elastic assembly (Fig 18, ¶185); and a fifth cam structure (982 second cam) is disposed at an end portion that is of the third gear (950 third shaft) and that faces the second conjoined cam (Fig 18), a sixth cam structure (984 fourth cam)is disposed at an end portion that is of the second gear (960 fourth shaft) and that faces the second conjoined cam (Fig 18), the second conjoined cam comprises a seventh cam structure (981 first cam) and an eighth cam structure (983 second cam), and under the action of the elastic force of the elastic assembly, the seventh cam structure abuts against the fifth cam structure, and the eighth cam structure abuts against the sixth cam structure (Fig 18, ¶185). Kim fails to teach the damping assembly further comprises a second conjoined cam, the elastic assembly is between the first conjoined cam and the second conjoined cam.

Kim and Liao are both in the industry of foldable display hinge support structures therefore it would have been obvious to a person having ordinary skill in the art to modify the single cam grouping of Kim to include the multiple cam groups separated by the spring structures of Liao in order to provide a damping “self-hovering” effect during folding and unfolding the hinge (Liao col 16 lines 16-24) Regarding claim 33, Kim teaches the hinge mechanism according to claim 32, wherein the synchronization assembly further (cross section shown in Fig 16, expanded view on Fig 8) comprises a third gear (gear disposed on 950 third shaft) and a fourth gear (gear disposed on 960 fourth shaft) the third gear and the fourth gear are engaged with each other(Fig 16), and the third gear and the fourth gear are located on a side of the second conjoined cam that is other that a side of the second conjoined cam that is closest to the elastic assembly (Fig 18, ¶185); and a fifth cam structure (982 second cam) is disposed at an end portion that is of the third gear (950 third shaft) and that faces the second conjoined cam (Fig 18), a sixth cam structure (984 fourth cam)is disposed at an end portion that is of the second gear (960 fourth shaft) and that faces the second conjoined cam (Fig 18), the second conjoined cam comprises a seventh cam structure (981 first cam) and an eighth cam structure (983 second cam), and under the action of the elastic force of the elastic assembly, the seventh cam structure abuts against the fifth cam structure, and the eighth cam structure abuts against the sixth cam structure (Fig 18, ¶185). Kim fails to teach the damping assembly further comprises a second conjoined cam, the elastic assembly is between the first conjoined cam and the second conjoined cam. However, Liao teaches the damping assembly further comprises a second conjoined cam (161b cam structure), the elastic assembly (combination of 173a abutment spring and 1174 retainer spring) is between the first conjoined cam and the second conjoined cam (Fig 10 and Fig 14). Kim and Liao are both in the industry of foldable display hinge support structures therefore it would have been obvious to a person having ordinary skill in the art to modify the single cam grouping of Kim to include the multiple cam groups separated by the spring structures of Liao in order to provide a damping “self-hovering” effect during folding and unfolding the hinge (Liao col 16 lines 16-24) Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Cho (US 20220317730 A1), Lee et. al (US 20220217859 A1), and Yun et. al (US 20220210937 A1) all teach a foldable display device with a hinge support structure including a cam and spring structure.
