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. 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. Claim(s) 4, 5, 12, 13 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pang et al. (hereinafter Pang) (US20220085318) in view of Campagna et al.

It would’ve been obvious to one of ordinary skill in the art, before the effective filing date of the invention to incorporate the cover glass of Campagna into the display device of Pang. One having ordinary skill on the art would have been motivated to do this to protect the display panel. Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pang et al. (hereinafter Pang) (US20220085318) in view of Park et al. (hereinafter Park) (US20160227678). Regarding claim 9, Pang discloses the display device of claim 1, wherein the second substrate (400) includes a plate-shaped circuit board body (Figure 4). Pang discloses, in at least paragraph 0077, discloses the second circuit board (400) comprises a timing controller and a connector, terminal for (420); however, Pang does not expressly disclose [wherein] the second substrate further includes a plurality of elements and a connector disposed on the circuit board body, and wherein the plurality of elements and the connector are disposed on a rear surface of the circuit board body. Park discloses a substrate including a plurality of elements and a connector (556) disposed on the circuit board body (Paragraph 0080 – Since the control PCB includes various driving circuits, such as a timing controller, disposed thereon…), and wherein the plurality of elements and the connector are disposed on a rear surface of the circuit board body. It would’ve been obvious to one of ordinary skill in the art, before the effective filing date of the invention to incorporate the board configuration of Park into the display device of Pang. One having ordinary skill on the art would have been motivated to do this create a more efficient use of the surface area of the second substrate. Allowable Subject Matter Claims 3, 6-8, 10, 11, 14, 15, 17 and 18 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
