DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. 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 (s) 1 -6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park et al. (US 2018/0088392 A1) (“Park”), in view of Lee et al. (US 2018/0134007 A1) (“Lee”) and Park et al. (US 2019/0143638 A1) (“Park 2”). With respect to claim 1, Park discloses a screen cover configured to cover a flexible display ( abstr ., 0006, 0007), the screen cover comprising a buffer layer – element 13 – comprising a first side – implied - configured to be positioned away from the flexible display and a second side configured to be positioned close to the flexible display ( 0056, Figs. 3 and 7) , wherein the buffer layer is configured to absorb stress of impact from a secondary object through elastic deformation – implied in par. [0056]-[0059], a second film layer – element 11 - covering the second side of the buffer layer and a second adhesive layer – element 14 – bonding the second film layer to the second side of the buffer layer (0048, 0060, Figs. 3 and 7). Park is silent with respect to the first film layer and a first adhesive layer bonding the first film layer to the first side of the buffer layer. Lee discloses a screen cover for a flexible display device ( abstr .), the screen cover including a first film layer – element 120 attached to a second side of a buffer layer – element 130 (0011, 0046, Fig. 1), the configuration of the buffer layer between two film layers providing for improved impact resistance of the cover (0009, 0011, 0044, 0045). It would have been obvious to one of ordinary skill in the art prior to the effective filing date of the claimed invention to provide the screen cover of Park with a first film layer as disclosed in Lee for improved impact resistance. Lee is silent with respect to the first adhesive layer as recited in the claim, however, since Park discloses an adhesive layer bo n ding the second film layer to the second side of the buffer layer, it would have been obvious to one of ordinary skill in the art to include a first adhesive layer bonding the first film layer to the first side of the buffer layer of Park. Regarding a first modulus of the first film layer being greater than a third modulus of the buffer layer and a second modulus of the second film layer being greater than the third modulus , Park discloses a modulus of the buffer layer of 7-30 MPa ( abstr ., 0008), while Lee discloses modulus of the film layer of no less than 1.5 GPa (0016) . Park 2 discloses a screen cover for a flexible display ( abstr ., 0005, 0006), wherein a film layer – the first base member - has a modulus greater than the buffer layer (0007, 0017-0019, 0101), the cover having improved impact resistance to an external impact (0005). It would have been obvious to one of ordinary skill in the art prior to the effective filing date of the claimed invention to form the screen cover of Park and Lee wherein a first modulus of the first film layer is greater than a third modulus of the buffer layer and a second modulus of the second film layer is greater than the third modulus, as such configuration is known in the art of screen covers for flexible displays as it improves impact resistance to an external impact. Regarding claim 2, Park, Lee and Park 2 teach the cover of claim 1. Park discloses the thickness of the second film layer of about 10 µm to about 150 µm (0050). The range of thickness overlaps the range recited in claim 2; overlapping ranges have been held to establish prima facie obviousness (MPEP 2144.05). As to claim 3, Park, Lee and Park 2 teach the cover of claim 1. Park discloses the thickness of the second film layer of about 10 µm to about 150 µm (0050). The range of thickness overlaps the range recited in claim ; overlapping ranges have been held to establish prima facie obviousness (MPEP 2144.05). With respect to claim 4, Park, Lee and Park 2 teach the cover of claim 1. Lee discloses modulus of the film layer of equal or greater than 1 GPa (0016), thus, it would be obvious to one of ordinary skill in the art to form the second modulus in the cover according to the references as disclosed in Lee, as such modulus of films is known in the art of screen covers for flexible displays. Regarding claim 5, Park, Lee and Park 2, teach the cover of claim 1. Park discloses the second film layer – element 11 - comprises colorless polyimide or polyester (0048, 0049). As to claim 6, Park, Lee and Park 2 teach the cover of claim 1. Lee discloses the first and second film layers made of the same material (0047).
