OFFICE ACTION:
DETAILED ACTION
Notice of Pre-AIA  or AIA  Status
This action is in response to the application filed 6 May 2024 which is a Continuation in Part of applications 17/951,397 and 17/872,094, now US Patents 12,172,761 and 11,999,494 respectively, filed 23 September 2022 and 25 July 2022 respectively. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA  as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer.
Claims 1-21 and 26 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 5-11 of U.S. Patent No. 11,999,494 and claims 1-10 of U.S. Patent No. 12,172,761.

APPLICANT REBUTTAL: REMARKS
The present application included claims 1-26. Claims 1, 7, 22, and 26 have been amended. Claim 2 was canceled without prejudice or disclaimer. New claim 27 has been added.1
Claims 1-21 and 26 were rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3 and 5-11 of U.S. Patent No. 11,999,494, and claims 1-10 of U.S. Patent No. 12,172,761 (the "reference patents"). The Applicant is concurrently filing terminal disclaimers with respect to the reference patents to render these rejections moot.
Claims 1 and 22-26 were rejected as being anticipated by U.S. 2017/0050737 ("Hartman").  Claims 1 and 3-11 were rejected as being anticipated by U.S. 3,679,025 ("Rummel"). Claims 1 and 12-21 were rejected as being anticipated by U.S. 3,866,734 ("Elkins").
In order to expedite prosecution toward allowance, claim 1 has been amended to recite the limitations of previously pending claim 2, which was objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form. See April 2, 2025 Office Action at page 2. Claims 22 and 26 have been similarly amended. Accordingly, claims 1, 22, 26, and any claims depending therefrom are in condition for allowance.
The claim amendments are not to be interpreted as an acknowledgement of the propriety of the claim rejections. Instead, as noted above, the claims have been amended to expedite prosecution toward allowance. The Applicant reserves the right to pursue the subject matter of the claims, as previously recited, in a continuation application.
In general, the Office Action makes various statements regarding the pending claims and the cited references that are now moot in light of the above. Thus, the Applicant will not address such statements at the present time. However, the Applicant expressly reserves the right to challenge such statements in the future should the need arise (e.g., if such statements should become relevant by appearing in a rejection of any current or future claim).
1 No fee is due with respect to new claim 27, as it replaces canceled claim 2.
The Applicant respectfully requests reconsideration of the claim rejections for at least the reasons discussed above. If the Examiner has any questions or the Applicant can be of any assistance, the Examiner is invited to contact the undersigned attorney.
