Office Action

§102
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 . Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1, 9-11, 17, 21 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Yoo (20190157612). PNG media_image1.png 286 400 media_image1.png Greyscale Regarding claim 1, Yoo teaches an display apparatus comprising: a display panel (par. 7); and an encapsulation film (fig. 3: 1) on the display panel, the encapsulation film including: an adhesive layer (fig. 3: 13; par. 69); and an oxygen barrier layer (par. 57-86) on the adhesive layer, the oxygen barrier layer including: binder resin (par. 68), and oxygen collecting particles dispersed in the binder resin, the oxygen collecting particles including a first metal oxide that includes a crystal structure consisting of first metal sites and oxygen sites, wherein the crystal structure is in an oxygen deficiency state (par. 58-60). Regarding claim 9, Yoo teaches an display apparatus according to claim 1, wherein the oxygen barrier layer includes the oxygen collecting particles at a content of 0.5 to 50 wt % based on a total weight of the oxygen barrier layer (par. 65, 121). Regarding claim 10, Yoo teaches an display apparatus according to claim 1, wherein the oxygen barrier layer has a thickness of 5 to 50 μm (par. 67, 119). Regarding claim 11, Yoo teaches an display apparatus according to claim 10, wherein the oxygen barrier layer has a thickness of 5 to 20 μm (par. 67, 119). Regarding claim 17, Yoo teaches an display apparatus according to claim 1, wherein the encapsulation film further includes a moisture barrier layer disposed on the oxygen barrier layer, and the moisture barrier layer includes adhesive resin and absorbent dispersed in the adhesive resin (par. 20). Regarding claim 21, Yoo teaches a encapsulation film comprising: an adhesive layer (par. 7); and an oxygen barrier layer on the adhesive layer, the oxygen barrier layer including: binder resin (par. 68), and oxygen collecting particles dispersed in the binder resin, the oxygen collecting particles including a first metal oxide that includes a crystal structure consisting of first metal sites and oxygen sites, wherein the crystal structure is in an oxygen deficiency state (par. 58-60). Claims 1-8, 12-14, 21-26 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Kim (20220209185). PNG media_image2.png 429 576 media_image2.png Greyscale Regarding claim 1, Kim teaches a display apparatus comprising: a display panel (fig. 3: DA); and an encapsulation film (fig. 3: 140) on the display panel, the encapsulation film including: an adhesive layer (fig. 3: 141); and an oxygen barrier layer (fig; 3: 143 + 143a) on the adhesive layer, the oxygen barrier layer including: binder resin (fig. 3: 143; par. 74), and oxygen collecting particles dispersed in the binder resin, the oxygen collecting particles including a first metal oxide that includes a crystal structure consisting of first metal sites and oxygen sites, wherein the crystal structure is in an oxygen deficiency state (fig. 3: 143a; par. 76-78). Regarding claim 2, Kim teaches a display apparatus according to claim 1, wherein the first metal oxide is in a reduced state (par. 77-80).
