Office Action

§102 §103 §DP
DETAILED ACTION 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 Remarks, filed 4/01/2026, with respect to the amended claims for the 112 rejections have been fully considered and are persuasive. The 112 rejection of claim 9 has been withdrawn. Applicant's arguments filed 4/1/2026 have been fully considered but they are not persuasive. Applicant argues that Steeg does not teach a cationic polyacrylamide but instead teaches a cationic polyamine based polymer and cited [0036-0037]. Applicant argues that Steeg teaches only cationic polymers that in some form or another are polyamine based. The Examiner respectfully disagrees. Steeg teaches a cationic second component of the invention. In [0036] Steeg teaches that “the second component of the present invention is a cationic polyamine-based polymer. Polyamines and related polymerics are frequently used in paper production, often to improve the dry strength of paper.” Steeg teaches that polyamines and related polymerics are usable. The cited [0037] even goes as far as explicitly stated that the cationic copolymers are “acrylamide copolymers produced from the reaction of acrylamide and ethylenically unsaturated cationic monomers”. The Rejection cites in [0038]: “Cationic polymers useful in the present invention include polymers produced by co-polymerization of cationic monomers with acrylamide. Typical cationic monomers used in this co-polymerization include, but are not limited to, the aminoalkylacrylate esters and their quaternary ammonium salts”, which provides the exact same steps as the instant claim. The claim is anticipated if all of the claimed limitations are directly taught by the reference. Steeg teaches all of the claimed steps in [0038]. The fact that Steeg teaches polyamines and polyamides does not teach away from the use of polyamides. Even if the copolymer was a polyamine that included a copolymer of an acrylamide monomer reacted with a cationic monomer of the claim, then it would still read on the open ended claim. Additional monomers can be present without a teaching away from the direct teaching of “Cationic polymers useful in the present invention include polymers produced by co-polymerization of cationic monomers with acrylamide. Typical cationic monomers used in this co-polymerization include, but are not limited to, the aminoalkylacrylate esters and their quaternary ammonium salts”. The rejections stand in view of the claims as currently written. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. The rejections provided on 2/05/2026 are maintained. Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. The rejections provided on 2/05/2026 are maintained. 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 1-12 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over the claims of copending Application No. 19/023807 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the claims are practically identical. The ‘807 application requires all of the same materials and steps of the instant application and also includes two additional cationic monomers that can be part of the second monomer in addition to the same claimed ones in the instant application. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. 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.
