Office Action

§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 . Claim Rejections - 35 USC § 112 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 1, 2, 8, 12, 13, and 31-35 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 1, applicants have failed to specify the bases for the weight precent ranges, added by amendment. It is unclear if the weight percent ranges are based on the weight of the article or polyurethane-based resin or some other entity. Secondly, with respect to claim 1, it ius unclear how to interpret the claimed weight percent ranges of the hard segment content and the soft segment content, because the total of the hard segment content and soft segment content does not sum to 100%; as accepted by convention a total of 100% is expected. Thirdly, with respect to claim 1, the claimed percent range for the polyglycol renders the claims indefinite, because the claimed endpoints are identical and therefore the language fails to recite a meaningful range limitation. 4. The severity of the indefiniteness issues precludes further meaningful analysis of the prior art. Furthermore, in view of these issues, applicants’ remarks are not commensurate in scope with the claims. 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.
