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 . Allowable Subject Matter Claims 1-5, and 8-15 are allowed. The following is an examiner’s statement of reasons for allowance: Claims are allowed based on applicant’s arguments submitted 5/5/2026. In particular, see page 8, paragraph 2. 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.” Claim 7 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. Specifically, if the claim were amended to depend from claim 1, which has incorporated the previous limitations of claim 6, rather than to depend from claim 6 which has been cancelled. Claim Rejections - 35 USC § 112 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claim 7 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 7 depends from claim 6; however claim 6 has been cancelled, so it is unclear what additional limitations claim 7 includes based on its dependency. For purposes of examination, it is assumed to depend from claim 1 which has been amended to include the previous limitations of claim 6. Examiner attempted to contact the applicant’s attorney in order to propose an examiner’s amendment changing the claim’s dependency so that claim 7 depends from claim 1. Applicant’s attorney is invited to contact the examiner at the number below to request an examiner’s amendment to remedy the rejection of claim 7 under 35 USC 112. Conclusion 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.
