Office Action

§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 . 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, 9-10, 12-13 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. In claim 1, there is no antecedent basis for “the nonwoven fabric”. There is antecedent basis for “the biodegradable spunbond nonwoven fabric” as set forth in line 1 of claim 1, but not for “the nonwoven fabric”. With regard to the response to the ex parte Quayle action, Applicant’s response has been considered but it is not fully responsive. Specifically, with regard to paragraphs 0011 and 0033, while Applicant relies on an error in the translation, Applicant does not point to the original document and which word was mistranslated, since it is required that the translation be a literal translation. The rest of the amendments, including the one to paragraph 0012, do not constitute adding new matter to the specification. Since this action includes a new rejection, this action is not made final and prosecution has been re opened. Any inquiry concerning this communication or earlier communications from the examiner should be directed to ELIZABETH M IMANI whose telephone number is (571)272-1475. The examiner can normally be reached Monday-Wednesday 7AM-7:30; Thursday 10AM -2 PM.
