Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 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. Claim(s) 7 and 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Silva in view of Montazeri, (USNO.2017/0094823). As for claim 7 and 15, Silva discloses all limitations, but differs from the claimed invention because he does not explicitly disclose at least one cutout comprises at least one semicircular cutout and cutout of the stacking adaptor is a semicircular cutout Montazeri discloses and showsin Figs. 5 and 16 at least one cutout (via magnets) comprises at least one semicircular cutout and cutout of the stacking adaptor is a semicircular cutout (par.[0073]) Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention was made to have modified the teachings of Silva by using at least one cutout comprises at least one semicircular cutout and cutout of the stacking adaptor is a semicircular cutout for advantages such as providing a secure support to the housing (par.[0077]), as taught by Montazeri.
