Office Action

§112
DETAILED DESCRIPTION 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 . Summary of Response The 07/10/2025 response includes: (a) the specification is currently amended; (b) claims 1, 6, 11 and 16-17 are currently amended; (c) claims 2-5, 7-10, 12-15 and 19-20 are original; (d) claim 18 is canceled. Claims 1-17 and 19-20 are currently pending and an office action on the merits follows. Response to Arguments Applicant’s arguments filed 07/10/2025 with respect to the rejection of claims 1-17 and 19-20 under 35 U.S.C. 102(a)(2) and 35 U.S.C. 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new grounds of rejection of claims 1-16 is made below based on lack of written description and indefiniteness. Also, new objections to claims 1-16 are made below. Claims 17-20 are allowed. Claim Objections Claims 1-16 are objected to because of the following informalities: Claim 1 at lines 11 and 14 includes “the display area” that lacks antecedent basis. This objection may be overcome, for example, by amending line 11 to “a display area”. Appropriate correction is required. This objection applies to claims 2-5 that depends upon claim 1. Claim 1 at lines 11 and 15 includes “the first resolution” that lacks antecedent basis. This objection may be overcome, for example, by amending line 11 to “a first resolution”. Appropriate correction is required. This objection applies to claims 2-5 that depends upon claim 1. Claim 1 at lines 12 and 16-17 includes “the gate signal” that lacks antecedent basis. This objection may be overcome, for example, by amending line 12 to “a gate signal”. Appropriate correction is required. This objection applies to claims 2-5 that depends upon claim 1. Claim 1 at line 12 includes “the first area” that lacks antecedent basis. This objection may be overcome, for example, by amending it to “a first area”. Appropriate correction is required. This objection applies to claims 2-5 that depends upon claim 1. Claim 1 at line 15 includes “the second resolution” that lacks antecedent basis. This objection may be overcome, for example, by amending it to “a second resolution”. Appropriate correction is required. This objection applies to claims 2-5 that depends upon claim 1. Claim 1 at line 17 includes “the second area” that lacks antecedent basis. This objection may be overcome, for example, by amending it to “a second area”. Appropriate correction is required. This objection applies to claims 2-5 that depends upon claim 1. Claim 6 at lines 16 and 19 includes “the display area” that lacks antecedent basis. This objection may be overcome, for example, by amending line 16 to “a display area”. Appropriate correction is required. This objection applies to claims 7-16 that depends upon claim 6. Claim 6 at line 16 includes “the first resolution” that lacks antecedent basis. This objection may be overcome, for example, by amending line 16 to “a first resolution”. Appropriate correction is required. This objection applies to claims 7-16 that depends upon claim 6. Claim 6 at line 17 includes “the first area” that lacks antecedent basis. This objection may be overcome, for example, by amending it to “a first area”. Appropriate correction is required. This objection applies to claims 7-16 that depends upon claim 6. Claim 6 at line 20 includes “the second resolution” that lacks antecedent basis. This objection may be overcome, for example, by amending it to “a second resolution”. Appropriate correction is required. This objection applies to claims 7-16 that depends upon claim 6. Claim 6 at line 22 includes “the second area” that lacks antecedent basis. This objection may be overcome, for example, by amending it to “a second area”. Appropriate correction is required. This objection applies to claims 7-16 that depends upon claim 6. Claim 11 at line 3 includes “the respective ones of the pixel lines” that lacks antecedent basis. This objection may be overcome, for example, by amending it to “respective ones of the pixel lines”. Appropriate correction is required. This objection applies to claim 12 that depends upon claim 11. Claim Rejections – 35 USC §112 5. The following is a quotation of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. 6. Claims 1-16 are rejected under 35 U.S.C. 112(a), as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for pre-AIA the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 1 at lines 10 and 14 includes at lines 16-17 “the plurality of signal transmission parts sequentially supply the gate signal to the gate line arranged in the second area”, however the specification describes the signal transmission parts sequentially supplying gate signals (i.e., a plurality of signals and not a single gate signal)(see e.g., ¶00701). In other words, the same single signal is not output simultaneously and sequentially by plurality of signal transmission parts but instead respective different ones of signals are output by each of the signal transmission parts. This grounds of rejection applies to claims 2-5 that depend upon claim 1. Claim 6 at lines 21-22 include the same issue as claim 1. This grounds of rejection applies to claims 7-16 that depend upon claim 6. Thus, applicants have both failed to satisfy their obligation to the public of disclosing their technical knowledge upon which this claim is based and failed to demonstrate to demonstrate that they were in possession of the invention that is claimed. MPEP §2163. 7. 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. 8. Claims 1-16 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 lines 10 and 14 includes at lines 10-11 “the gate line in the display area”, however it is unclear whether applicant is referring to (i) “a first gate line” in claim 1 at line 5; (ii) “a second gate line” in claim 1 at line 8; or to (iii) another gate line different than the first and second gate lines. Appropriate correction is required. This grounds of rejection applies to claims 2-5 that depend upon claim 1. Claim 1 at line 12 includes “the gate line in the first area”, however it is unclear whether applicant is referring to (i) “a first gate line” in claim 1 at line 5; (ii) “a second gate line” in claim 1 at line 8; or to (iii) another gate line different than the first and second gate lines. Appropriate correction is required. This grounds of rejection applies to claims 2-5 that depend upon claim 1. Claim 1 at line 17 includes “the gate line in the second area”, however it is unclear whether applicant is referring to (i) “a first gate line” in claim 1 at line 5; (ii) “a second gate line” in claim 1 at line 8; or to (iii) another gate line different than the first and second gate lines. Appropriate correction is required. This grounds of rejection applies to claims 2-5 that depend upon claim 1. Claim 6 at lines 15-16 “the gate line in the display area”, however it is unclear whether applicant is referring to (i) “a first gate line” in claim 6 at lines 10-11 and 13; (ii) “a second gate line” in claim 6 at line 13; or to (iii) another gate line different than the first and second gate lines. Appropriate correction is required. This grounds of rejection applies to claims 7-16 that depend upon claim 6. Claim 6 at line 17 includes “the gate line arranged in the first area”, however it is unclear whether applicant is referring to (i) “a first gate line” in claim 6 at lines 10-11 and 13; (ii) “a second gate line” in claim 6 at line 13; or to (iii) another gate line different than the first and second gate lines. Appropriate correction is required. This grounds of rejection applies to claims 7-16 that depend upon claim 6. Claim 6 at line 22 includes “the gate line in the second area”, however it is unclear whether applicant is referring to (i) “a first gate line” in claim 6 at lines 10-11 and 13; (ii) “a second gate line” in claim 6 at line 13; or to (iii) another gate line different than the first and second gate lines. Appropriate correction is required. This grounds of rejection applies to claims 7-16 that depend upon claim 6. Allowed Claims 9. Claims 17-20 are allowed. Reasons for Allowance 10. The following is examiner’s statement of reasons for allowance: the claimed invention is directed to: PNG media_image1.png 200 400 media_image1.png Greyscale PNG media_image2.png 811 325 media_image2.png Greyscale Independent claim 17 identifies the distinct features: “the first pixel(FIGs. 2, 14: red pixel directly connected to gate line G3, SWC9) and the second pixel(FIGs. 2, 14: red pixel directly connected to gate line G9, SWC9) arranged with respect to one another in a second direction(FIG. 2: y-axis direction) that traverses the first direction(FIG. 2: x-axis direction)”, with all other limitations as claimed. The closest prior art, U.S. Patent Pub. No. 2024/0144887 A1 to Gohardehi et al. (“Gohardehi”), either singularly or in combination, fails to anticipate or render obvious the above underlined features associated with other features of this claim as explained in the 04/10/2025 office action. Other Relevant Prior Art 11. Other relevant prior art includes: U.S. Patent Pub. No. 2021/0398491 A1 to Kwak et al.
