Office Action

§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. Specification The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. 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 1-7 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 recites the limitation "the etching mask" in line 13 of the claim. There is insufficient antecedent basis for this limitation in the claim. Due to their dependency, claims 2-7 are necessarily included in this rejection. Allowable Subject Matter Claims 1-7 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The following is a statement of reasons for the indication of allowable subject matter: Regarding independent claim 1, the prior art of record neither shows nor suggest a method of fabricating a display device, comprising: preparing a substrate including an emission area and a subarea; forming a first alignment line and a second alignment line which are disposed in the emission area and the subarea and are spaced apart from each other; arranging light-emitting elements between the first alignment line and the second alignment line in the emission area; forming a first insulating layer on the light-emitting elements to expose end portions of each of the light-emitting elements; forming a contact electrode material layer on the first insulating layer; using chemical mechanical polishing (CMP) to expose part of the contact electrode material layer; and forming a first contact electrode and a second contact electrode by removing the part of the contact electrode material layer using the etching mask, wherein the part of the contact electrode material layer exposed by the etching mask is disposed on a top surface of the first insulating layer, the first contact electrode and the second contact electrode are spaced apart from each other, and the first insulating layer is disposed between the first contact electrode and the second contact electrode. Due to their dependency, claims 2-7 would also be allowable. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 12,477,882 teaches the state of the art of a method of manufacturing a display device.
