Allowable Subject Matter
Claims 4-12 and 21 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Response to Arguments
Applicant's arguments filed 10/14/2025 have been fully considered but they are not persuasive. Examiner respectfully disagrees with the applicant’s argument that “Claim 1 is amended by rewriting the dependent claim 15 in independent form including all the limitation of the base claim” (Page 2 of applicant’s remarks).
Claim 1 has not been amended by rewriting the dependent claim 15 in independent form including all the limitation of the base claim and any intervening claims. Applicant has deleted the claim limitations in lines 19-38 of claim 1. Furthermore, all of the claim limitations of intervening claim 13 which claim 15 depended on, are not incorporated into claim 1.
The cited prior art teaches applicant’s claimed invention as noted in the office action above.
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.
