Office Action

§102 §103 §112
DETAILED ACTION 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 In response to a Restriction Requirement filed on 10/22/2025, the Applicant elected without traverse Group I (claims 1-16 and 20) and withdrew claims 17-19 of the non-elected Group II in a reply filed on 12/22/2025. Currently, claims 1-16 and 20 are examined as below. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement Acknowledgment is made of applicant's Information Disclosure Statements (IDS) filed on 05/26/2023 and 06/13/2025. The IDS have been considered. 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. The following title is suggested: (Marked-Up Version) Display Panel and Display Device With Reduced Reflectivity (Clean Version) Display Panel and Display Device With Reduced Reflectivity 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 5 and 14 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 5 is indefinite, because: (1) The limitation “a first end surface” in line 2 renders the claim indefinite. It is unclear whether such first end surface is a first end surface of the display panel or of the connection terminal. The limitation will be interpreted as a first end surface of the connection terminal. (2) The limitation “a second end surface” in lines 3-4 renders the claim indefinite. It is unclear whether such second end surface is a second end surface of the display panel or of the connection terminal. The limitation will be interpreted as a second end surface of the connection terminal. Claim 14 is indefinite, because the limitation “the same light-emitting color” in line 3 is not mentioned before. There is insufficient 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 1-5, 7, 10, 13-16 and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2021/0408104 A1 to Lee et al. (“Lee”).

Claim Rejections - 35 USC § 103 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 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, 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 6, 8-9 and 11-12 are rejected under 35 U.S.C. 103 as being unpatentable and obvious over Lee. Regarding claim 6, Lee does not explicitly disclose an aperture diameter of the second opening is equal to an outer diameter of the connection terminal. However, it would have been obvious to form the aperture diameter of the second opening and the outer diameter of the connection terminal within the claimed range, since it has been held by the Federal circuit that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. (In Gardner v. TEC Systems, Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984)). Regarding claim 8, Lee in Annotated Figs. 5A and 12A further teaches the pixel unit PXU1, PXU2 comprises a first-color light-emitting element LD/LDr (¶ 241-¶ 242, light emitting element LD includes first color light emitting element LDr) and a second-color light-emitting element LD/LDg (¶ 241-¶ 242, light emitting element LD includes second color light emitting element LDg), a first gap (Annotated Figs. 5A & 12A) is formed between the first-color light-emitting element LDr and a wall surface of the seconding opening OP2 where the first-color light-emitting element LDr is located, a second gap (Annotated Figs. 5A & 12A) is formed between the second-color light-emitting element LDg and a wall surface of the seconding opening OP2 where the second-color light-emitting element LDg is located. Lee does not explicitly disclose the first gap is greater than the second gap. However, it would have been obvious to form the first gap and the second gap within the claimed range, since it has been held by the Federal circuit that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. (In Gardner v. TEC Systems, Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984)). Regarding claim 9, Lee does not explicitly disclose a ratio of a thickness of the connection terminal to the thickness of the second shielding structure in the first direction is greater than 1. However, it would have been obvious to form the ratio within the claimed range, since it has been held by the Federal circuit that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. (In Gardner v. TEC Systems, Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984)). Regarding claim 11, Lee in Annotated Figs. 5A and 12A further teaches the pixel unit comprises a first-color light-emitting element LDr (¶ 241-¶ 242, first color light emitting element LDr), a second-color light-emitting element LDg (¶ 241-¶ 242, second color light emitting element LDg) and a third-color light-emitting element LDb (¶ 241-¶ 242, third color light emitting element LDb); in the first direction, a portion of the first shielding structure BNK2 located between the first-color light-emitting element LDr and the second-color light-emitting element LDg has a first height (Annotated Fig. 12A), and a portion of the first shielding structure BNK2 located between the second-color light-emitting element LDg and the third-color light-emitting element LDb has a second height (Annotated Fig. 12A). Lee does not explicitly disclose the first height is greater than the second height. However, it would have been obvious to form the first height and the second height within the claimed range, since it has been held by the Federal circuit that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. (In Gardner v. TEC Systems, Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984)). Regarding claim 12, Lee in Figs. 5A and 12A further teaches the display panel PNL has a first region PXU1 (Fig. 12A & ¶ 272, first pixel unit PXU1) and a second region PXU2 (Fig. 12A & ¶ 272, second pixel unit PXU2), and the pixel unit PXU1, PXU2 comprises a first-color light-emitting element LDr (¶ 241-¶ 242, first color light emitting element LDr) and a second-color light-emitting element LDg (¶ 241-¶ 242, second color light emitting element LDg); in the first region PXU1, the first shielding structure BNK2 between at least one first-color light-emitting element LDr and an adjacent second-color light-emitting element LDg has a third height in the first direction (Fig. 12A); in the second region PXU2, the first shielding structure BNK2 between at least one first-color light-emitting element LDr (Fig. 12A) and an adjacent second-color light-emitting element LDg (Fig. 12A) has a fourth height in the first direction (Fig. 12A). Lee does not explicitly disclose the third height is greater than the fourth height. However, it would have been obvious to form the third height and the fourth height within the claimed range, since it has been held by the Federal circuit that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. (In Gardner v. TEC Systems, Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984)).
