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 . Specification The abstract of the disclosure is objected to because of the use of the legalese language “comprises”. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). 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 8-12 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. Regarding claim 8, the limitation “claims 1” make the claim indefinite. It is not clear to the Examiner whether the limitation should read “claim 1” or “any one of claims 1- (fill in the number)”. Therefore, it is not clear to the Examiner what are the metes and bounds of the claim. Due to their dependency, claims 9-12 are necessarily included in this rejection. Allowable Subject Matter Claims 1-7 are allowed. The following is an examiner’s statement of reasons for allowance: Regarding independent claim 1, the prior art of record neither shows nor suggest a color semi-transparent partially erasable electronic writing film with code points, characterized by, comprising: a first conductive layer, an intermediate layer and a second conductive layer which are stacked in sequence, wherein the intermediate layer is a liquid crystal layer containing a code-point carbon element capsule array, which is obtained by free filling of a cholesteric liquid crystal composition between the first conductive layer and the second conductive layer, followed by UV curing and integral forming; and the cholesteric liquid crystal composition comprises the following raw materials in percent by mass: 75% to 85% of a nematic cholesteric liquid crystal, 1% to 10% of a code- point carbon element capsule, 4% to 15% of a UV adhesive and 0.1% to 0.3% of an isolation space powder; and the first conductive layer and the second conductive layer are transparent conductive electrode film layers made of an indium tin oxide (ITO) or a conductive polymer. Due to their dependency, claims 2-7 are necessarily allowable. Claims 8-12 would be allowable if rewritten 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 and to include all of the limitations of the base claim and any intervening claims. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Contact Information Any inquiry concerning this communication or earlier communications from the examiner should be directed to JOSEPH L WILLIAMS whose telephone number is (571)272-2465.
