Office Action

§DOUBLEPATENT
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 Amendment 1. This office action is responsive to communication(s) filed on 3/13/2026. 2. Claims 1 and 3-21 are presented for examination. 3. Claims under 35 U.S.C. § 112 and 103 are withdrawn. Response to Double Patenting Arguments 4. Applicant's arguments, ”Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 12,033,719. These rejections are traversed. It is respectfully requested that the double patenting rejection be held in abeyance.” The examiner disagreed because there is no arguments for a reason of these rejections traversed. However, the newly added limitations in claims 1, 10 and 16 are disclosed by a claim 12 of the reference ‘719. Applicants should provide the terminal disclaimers in order to overcome the rejection for obviousness-type double patenting over pending claims as rejected in the previous Office action including the newly added limitations. Response to Arguments 5. Applicants’ arguments have been fully considered but they are not persuasive. For the above reasons, it is believed that the rejections should be sustained. Feature of an invention not found in the claims can be given no patentable weight in distinguishing the claimed invention over the prior art. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. 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 mailing date of this final action. 6. When responding to the office action, Applicants are advised to provide the examiner with the line numbers and page numbers in the application and/or references cited to assist the examiner to locate the appropriate paragraphs. 7.
