Office Action

§102 §112
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 . Election/Restrictions Claims 9-11 and 15 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 11/24/2025 is acknowledged. After further consideration, the applicant argument is persuasive that Species 1 (FIG. 8A) and Species 2 (FIG. 8B) are sectional views taken along lines IV- IV' and V-V'. respectively, of the structure illustrated in FIG. 6. These figures represent different cross-sectional views of a single embodiment rather than distinct or mutually exclusive species. Accordingly, the claimed subject matter of FIGS. 8A and 8B pertains to the same inventive concept and structure, and does not recite mutually exclusive characteristics as asserted in the Restriction Requirement. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-8, 12-14, and 16-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 1 and 17 recites “the pixel circuit” lacks antecedent basis. 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-4, 6, 8, 12-14, 16-18 and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lee et al. 20220077271.

Regarding claim 17, figs. 1, 7A-7B and 8A-9 of Lee discloses a display panel comprising: a substrate comprising a central area FDA/SDA(1,2,3,4) and a corner area (CDA/MDA) extending from a corner of the central area, wherein the corner area comprises a first corner area MDA adjacent to the central area and a second corner area CDA outside the first corner area; a pixel circuit (figs. 3A/6A) disposed in the central area and a display element connected to the pixel circuit; a voltage supply line (as labeled by examiner above - fig. 7A) which is disposed in the corner area and supplies a voltage to one electrode of the pixel circuit (fig. 7A of shows the voltage supply line as labeled by examiner is connected to WL2 and par [0174] discloses that the second wiring WL2 may transfer a scan signal or an emission control signal to at least one of the first side display area SDA1, the second side display area SDA2, and the front display area FDA, scan signal which is voltage is transfer to transistor which is part of the pixel circuit); PNG media_image4.png 527 701 media_image4.png Greyscale a driving circuit BL (connected to LWL2) which is disposed in the second corner area (CDA - fig. 9 above) and supplies an electrical signal to the pixel circuit PC; and an input line LWL2 which is disposed outside the voltage supply line in the corner area and transmits a signal to the driving circuit BL (see fig. 8 showing LWL2 is connected to BL). PNG media_image5.png 609 1268 media_image5.png Greyscale Regarding claim 2, figs. 7A/8A (as labeled by examiner above) of Lee disclose wherein the corner area comprises a first corner area adjacent to the central area and a second corner area outside the first corner area, wherein the voltage supply line is disposed in the first corner area, and the driving circuit is disposed in the second corner area. Regarding claim 3, fig. 9 of Lee discloses further comprising a thin-film encapsulation layer disposed on the display element, wherein the thin-film encapsulation layer comprises a first inorganic encapsulation layer, an organic encapsulation layer on the first inorganic encapsulation layer, and a second inorganic encapsulation layer on the organic encapsulation layer.
