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 . DETAILED ACTION All the references cited in the International Search Report have been considered. None is anticipatory or meet the amended claims. The most pertinent of these references have been applied below. Election/Restrictions The applicant has elected Group I (claims 1-9) with traverse. The examiner withdraws the previous election of species requirement of Group I. This restriction is made FINAL. See previous action for the reasons of applying restriction. 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. Claim(s) 1-9 (is)are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Claim 1 fails to define Ac, which may have multiple meanings as an abbreviation of chemical groups known to one of ordinary skill in the art. Claims 2-9 depend upon claim 1 and fail to rectify the issue in claim 1. See MPEP § 2173.05(d). Allowable Subject Matter The following is an examiner's statement of reasons for allowance: Claim(s) 1-9 is(are) allowable over the closest prior art in proviso the above 112b issue is resolved: KOBILKA et al. (US 10035877) listed on IDS and ISR. Koblika discloses: PNG media_image1.png 214 353 media_image1.png Greyscale . Koblika fails to teach the claimed monomer of claim 1. Therefore, claims 1-9 is(are) provisionally allowable. 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”. The examiner urges cancelling non-elected polymer claims to facilitate the allowance. It is duly notified those polymers may be met by prior arts not listed on record.
