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 . Election/Restrictions Applicant's election with traverse of claims 1-8 and 10-12 in the reply filed on 11-28-25 is acknowledged. The traversal is on the ground(s) that the special technical feature is not taught by the prior art. This is found persuasive. The requirement is therefore withdrawn. 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. Claim 8 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. Claim 8 recites the limitation "the co-consolidation step" in lines 2-3 of the claim. There is insufficient antecedent basis for this limitation in the claim. Allowable Subject Matter Claims 1-7 and 9-12 are allowed. Claim 8 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. The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 1, the prior art does not teach the consolidated strand being interposed between the first consolidated preform and the second consolidated preform. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to XUE H LIU whose telephone number is (571)270-5522.
