Office Action

§102 §112
Detailed Office Action Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Indefiniteness Rejection 2. 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. 3. Claims 2, 3, 5, 6, 15, 16, 18, 19 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. Firstly with respect to claim 2, the compounds, “2-metylimidazole” and “2-ethyl-4-metylimidazole”, as presented are incorrect in view of the incorrect spelling of “methyl”. Secondly, with respect to claim 5, the language, “the electron acceptor moiety”, lacks antecedent basis. Prior Art Rejections 4. 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. 4. Claims 2, 3, 15, and 16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Zhang et al. (Facile construction of one-component intrinsic flame- retardant epoxy resin system with fast curing ability using imidazole-blocked bismaleimide). Zhang et al. disclose a latent curing agent for epoxy resin comprising a bismaleimide and 2-methylimidazole or 2-ethyl-4-methylimidazole. See abstract. Given the imide and imidazole structures, applicants’ claimed characteristics of claims 2 and 3 are inherently met. Conclusion 5. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. 6.
