Office Action

§112
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 4/28/2026 has been entered. Claim Term Meaning As stated previously, in the claims of the instant invention “between” is given its plain meaning and is understood to mean numbers greater than the low number and lower than the high number {i.e. A is between 1 and 10 = 1<A<10}. Claims have been examined in accordance with this claim term meaning. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1, 2, 13 and 14 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Applicants’ originally filed supporting disclosure lacks support for the now claimed values and ranges of values associate with “m” and “n” as currently expressed by claims 1,2, 13 and 14. Particularly, applicants’ originally filed supporting disclosure expresses “m” and “n” as percentages and is not supportive of the now claimed expression of “m” and “n” as unitless integers without the required accompanying expression that they are percentages (i.e.“ % ”). This is a new matter rejection. Additionally, claim 2 as now amended lacks support in the originally filed supporting disclosure in that support for “p” being integers as claimed and expressed as percentages of “m” as opposed to “n+m” is not evident in that which was originally provided at time of filing the instant application. This, too, is a new matter rejection. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 2 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 2 is confusing as to intent because it can not be definitively be determined what “p” values are intended to be allowed by applicants’ claim in that the claim recites that “p is an integer” but also recites that “p” may be “16.7%” which is not an integer. Accordingly, it can not be determined if applicants intend to limit the claims to integers or inclusion of non-integers as well. Appropriate correction is required. 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, 2, 13, 14 and 35-46 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 13, 14 and 34 of copending Application No. 19/483,712 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because they differ in make-up and overlap of material make-ups in a manner which would have been obvious to one having ordinary skill in the art before the effective date of the invention in order to arrive at the products of applicants’ claims with the expectation of success in the absence of a showing of new or unexpected results. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: Notwithstanding the above rejection under the heading “Double Patenting”, regarding claims 35-46, the prior art, including Chemtob(3,567,369) taken alone or in combination with Mattiasson et al.(2011/0117596) or other prior art, is insufficient in its teaching or fair suggestion of microporous polymeric adsorbent materials as defined by these claims that include the additionally recited polymerizable monomers set forth by this claim. Notwithstanding the above rejections under the heading “Double Patenting” and “35USC112”, regarding claims 1, 2, 13 and 14, as the claims currently stand, the prior art, including Chemtob(3,567,369) taken alone or in combination with Mattiasson et al.(2011/0117596) or other prior art, is insufficient in its teaching or fair suggestion of microporous polymeric adsorbent materials as defined by these claims that are in the form of or manufactured as a cryogel and have pores of the diameter as required by these claims. The holdings regarding allowable subject matter possessed by claims may need to be revisited upon any amendments being made to resolve rejections above under 35USC112 and/or Double Patenting. Response to Arguments Applicants’ arguments on reply have been considered. However, they are unpersuasive in light of the new grounds of rejection that are set forth above. Previous rejections under 35USC112 and 35USC102 are withdrawn in light of applicants’ amendments to the claims.
