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 . Foreign Priority This application is a continuation of U.S. Patent Application No. 18/404,179 filed on 01/04/2024 that claims priority to Korean Patent Application No. 10-2023-0084176 filed in the Korean Intellectual Property Office on 06/29/2023. On 08/05/2025, an electronic copy of this document was received by the USPTO, and thus on the office action summary sheet examiner has checked off the box “all” certified copies have been received at this time. Drawing Objection The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the following must be shown or the feature(s) canceled from the claim(s), while no new matter should be entered: Claims 1 and 18 each include first reference voltage generator including a first input terminal configured to receive the pixel drive voltage and a circuit drive voltage, however the figures do not depict a first of three input terminals that is configured to receive both the pixel drive voltage and a circuit drive voltage. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Specification Objection The specification is objected to because the title is not descriptive. See MPEP 606.01 – “Where the title is not descriptive of the invention claimed, the examiner should require the substitution of a new title that is clearly indicative of the invention to which the claims are directed”. Correction is needed. Examiner suggests by way of example the following title: “DISPLAY DEVICE CONFIGURED TO GENERATE A DATA SIGNAL BASED ON A MAXIMUM GAMMA VOLTAGE AND A MINIMUM GAMMA VOLTAGE, DISPLAY SYSTEM, AND DRIVING METHOD OF DISPLAY DEVICE”. 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 1-10 and 16 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. Claim 1 at line 16 includes “the ground voltage” that lacks antecedent basis. This grounds of rejection may be overcome, for example, by amending it to “a ground voltage”. Appropriate correction is required. This grounds of rejection applies to claims 2-10 that depend upon claim 1. Claim 2 at line 16 includes “the light” that lacks antecedent basis. This grounds of rejection may be overcome, for example, by amending it to “light”. Appropriate correction is required. Claim 5 at line 2 includes “the gate terminal of the second transistor” that lacks antecedent basis. This grounds of rejection may be overcome, for example, by amending it to “a gate terminal of the second transistor”. Appropriate correction is required. Claim 16 at line 2 includes “the pixel” that lacks antecedent basis. This grounds of rejection may be overcome, for example, by amending it to “a pixel”. Appropriate correction is required. Claim Rejections – 35 USC §102 7. The following is a quotation of the appropriate paragraphs of AIA 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 user, on sale or otherwise available to the public before the effective filing date of the claimed invention. Claims 11 and 13-17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Patent Pub. No. 2020/0211457 A1 to Kim et al. (“Kim”).
