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 Response to Amendment All previous rejections have been overcome by the amendment supported by the original disclosure. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. The previous restriction have been maintained and repeated. Claim Rejections - 35 USC § 112 Claim(s) 1-9, 11-12, and 14 (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 defines R5 can be an optionally substituted alkyl group. However, R5 is a divalent group and cannot be an alkyl group. Claims 2-9, 11-12, and 14 depend upon claim 1 and fail to rectify the issue in claim 1. See MPEP § 2173.05(d). For examination purpose, R5 is considered as an optionally substituted alkylene group. Response to Arguments The argument for allowance of amended claims has been fully considered but not persuasive. Applicant’s argument pertaining to the amendment has been rendered moot. 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 extension fee 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 date of this final action. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to SHANE FANG whose telephone number is (571)270-7378. The examiner can normally be reached on Mon-Thurs. 8am-6pm.
