Office Action

§103
DETAILED ACTION This Office action is in response to Applicant’s amendment filed April 7, 2025. Applicant has amended claims 19, 27 and 28. Claim 34 has been cancelled. Currently, claims 19-33 and 35 remain pending in the application. The text of those sections of Title 35 U.S. Code not included in this action can be found in the prior Office action, Paper No. 20251209. The objection of the first line of the specification is withdrawn in view of applicant’s amendments and remarks. The objection of claim 28 is withdrawn in view of applicant’s amendments and remarks. The rejection of claims 27-29 and 34 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, is withdrawn in view of applicant’s amendments and remarks. The rejection of claims 19-33 and 35 under 35 U.S.C. 103 as being unpatentable over Glenn, Jr. et al, US 2012/0270029, is maintained for the reasons of record. The rejection of claims 19-33 and 35 on the ground of nonstatutory double patenting as being unpatentable over claims 1-14 of U.S. Patent No. 12,084,631 is maintained for the reasons of record. The provisional rejection of claims 19-33 and 35 on the ground of nonstatutory double patenting as being unpatentable over claims 1-13 and 15-17 of copending Application No. 17/368,893 is maintained for the reasons of record. Furthermore, the examiner notes that copending Application No. 17/368,893 has issued as U.S. Patent No. 12,522,788. Response to Arguments Applicant's arguments filed April 7, 2026 have been fully considered but they are not persuasive. Applicant argues that Glenn, Jr. et al, US 2012/0270029, does not teach or suggest in general a dissolvable solid article wherein each of the two or more flexible, dissolvable, porous sheets contain no more than 30% by weight of the sheet of an unalkoxylated C6-12 linear or branched alkyl sulfate, as required by applicant in newly amended claim 19. However, the examiner respectfully disagrees. Specifically, the examiner respectfully maintains that Glenn, Jr. et al, US 2012/0270029, clearly meets this limitation. Specifically, Example 1 in Table 1 of Glenn, Jr. et al contains 15.9109% by weight of sodium C11 AS, and Examples 11-14 contain 18.2-19.9% by weight of Ammonium Undecyl sulfate, per the requirements of the instant invention. The examiner notes that applicant has requested that the obviousness-type double patenting rejections over U.S. Patent No. 12,084,631 and U.S. Patent No. 12,522,788 be held in abeyance until an indication of allowable subject matter in the instant application is identified. Conclusion 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 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.
