Office Action

§102 §103 §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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55, which papers have been placed of record in the file. Information Disclosure Statement The information disclosure statement (IDS) submitted on 10/18/2023 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Drawings The drawings were received on 10/18/2023. These drawings are considered acceptable by Examiner. 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. Claim(s) 1 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 pre-AIA the applicant regards as the invention. Claim 1 recites the limitation "the pixel electrodes" in line 4. There is insufficient antecedent basis for this limitation in the claim. For purposes of expediting prosecution, Applicant is advised that, when comparing the claim with the Prior Art, the Examiner is assuming, based on the originally filed description and drawings, that Examiner will interpret the initial introduction of the pixel electrode, of line 3, in its plural form. Claim(s) 2-11 are rejected at least for their dependency on Claim 1. America Invents Act 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 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. Claim Rejections - 35 USC § 102 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. 1.

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 of this title, 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. 2. Claim(s) 3, 14 are rejected under 35 U.S.C. 103 as being obvious over Yao et al., in view of Haas et al., (U.S. Pub. No. 2022/0102684 A1). Regarding Claim(s) 3, 14, Yao et al., teaches the invention set forth above (see rejection in the corresponding claim(s) above). Yao et al., is silent regarding/lacks a -. In the same field of endeavor, Haas et al., teaches a display device with an intermediate layer that further includes an organic functional layer (62) and a charge generation layer (66) in order to optimize and increase the luminance without sacrificing the operating lifespan (¶ [0005]). Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to add the additional layers to the intermediate layer, as disclosed by Haas et al., in the display of Yao et al., in order to optimize and increase the luminance without sacrificing the operating lifespan (¶ [0005]). 3. Claim(s) 9, 19 are rejected under 35 U.S.C. 103 as being obvious over Yao et al., in view of Byun et al., (U.S. Pub. No. 2021/0066419 A1). Regarding Claim(s) 9, 19, Yao et al., teaches the invention set forth above (see rejection in the corresponding claim(s) above). Yao et al., is silent regarding a spacer. In the same field of endeavor, Byun et al., teaches a display device wherein a spacer (115-1, first spacer, ¶ [0163]; see at least Figs. 4, 8) disposed on the pixel-defining layer (109 or 113), wherein the groove (indentation created to accommodate 20 or alternatively grooves in 113) is not located in the pixel-defining layer (109 or 113) where the spacer (115-1) is disposed in order to protect the display area from external moisture or impurities (¶ [0004]). Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to add the spacer, as disclosed by Byun et al., in the display of Yao et al., in order to protect the display area from external moisture or impurities (¶ [0004]). Furthermore, one of ordinary skill in the art would have been led to using a spacer as a matter of choice. Applicant(s) has not disclosed that the materials is for a particular unobvious purpose, produce an unexpected or significant result, or are otherwise critical and it appears prima facie that the process would possess utility using another configuration (In re Dailey, 357 F.2d 669, 149 USPQ 47 (CCPA 1966)). The phrase “wherein the groove is not located in the pixel-defining layer” does not recite a positive limitation and instead attempts to claim the disclosed invention by excluding what the applicants did not disclose or invent, rather than distinctly and particularly pointing out what the applicants did disclose or invent. Essentially this claim language fails to provide any structural element or concrete component. Examiner's Note The Examiner cites particular figures, paragraphs, columns and line numbers in the reference(s), as applied to the claims above. Although the particular citations are representative teachings and are applied to specific limitations within the claims, other passages, internally cited references, and figures may also apply. In preparing a response, it is respectfully requested that the Applicant fully consider the references, in their entirety, as potentially disclosing or teaching all or part of the claimed invention, as well as fully consider the context of the passage as taught by the reference(s) or as disclosed by the Examiner.
