Office Action

§112
DETAILED ACTION For this Office action, Claims 1-11 and 14-37 are pending. Claims 28-37 are new; Claims 1-10 have been withdrawn from consideration due to a prior restriction requirement, and Claims 12 and 13 have been canceled. 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 . Response to Arguments Applicant’s arguments, see Applicant Arguments/Remarks Made in an Amendment, filed 22 January 2026, with respect to the rejections of claims 1-11 and 14-27 under 35 U.S.C. 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, new grounds of rejection are made for claims 20, 24, 25, 28-33 and 37 in view of 35 U.S.C. 112(b). Applicant’s amendments overcome the teachings of the cited prior art, and the grounds of rejection are hereby withdrawn (see the arguments/remarks for more detail on why the grounds of rejection have been withdrawn). However, further consideration has raised new grounds of rejection under 35 U.S.C. 112(b), which are detailed below. 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. 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 20, 24, 25, 28-33 and 37 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. Each of these claims recites limitations that are considered optional, in particular for an optional third addition point. These limitations are considered indefinite because the claims are unclear whether the optional language is required to read on the claims or not. These rejections would also apply to similar limitations found in the withdrawn claims, should they be rejoined in a future action. For purposes of this examination, the examiner will assume the optional limitations are required. Allowable Subject Matter Claims 11, 14-19, 21-23, 26-27 and 34-36 are considered allowable over the prior art. The amendments to the respective independent claims have made the claims allowable at this time. A more detailed reasons for allowance will be provided when the entire claim set is considered allowable. 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.
