Office Action

§102 §112
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 . 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. Claim Rejections - 35 USC § 112 Claim 1 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. [0095] of the instant application recites the following: Optionally, referring to FIG. 4, in the embodiments of the present disclosure, the orthographic projection of the first light-shielding layer 10 on the base substrate 00 covers the orthographic projection of the active layer 40 on the base substrate 00. In this way, a better light-shielding effect can be further ensured. However, figure 4 and [0095] of the specification fails to enable a skilled artisan how to make and/or use “an orthographic projection of the first light-shielding layer on the base substrate covers an orthographic projection of the active layer on the base substrate” (emphasis added) as set forth in the penultimate line through ultimate line of claim 1. Claim 11 is 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. Specifically, line 3 of claim 11 “a third via hole” and “a fourth via hole” should be a first and second via hole respectively since there is no prior recitation of a first and second via hole. Also see lines 8 and 11 of claim 11.
