Office Action

§103 §112 §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 . Claim Interpretation The examiner makes of record that the instant claims contain two claims numbered as “claim 2”. Per Rule 1.126, the second occurrence of claim 2 will be renumbered as “claim 3”, and claims 3-20 will be renumbered as “claims 4-21”. Accordingly, claims 1-21 are pending. Applicant’s next response should reflect the renumbering of instant claims 1-21. Claim Objections Claims 2, 9-12, 14 and 21 are objected to because of the following informalities: In instant claim 2, the limitation “Number of isocyanate groups (NCO groups)” should be amended to recite “Number of NCO groups (isocyanate groups)” for consistency purposes with the equation. In instant claim 9, the term “is” should be inserted after “beta-aromatic isocyanate” for grammatical purposes. Claim 10 is included in this objection for being dependent upon claim 9. In instant claim 11, a space should be inserted before “polymeric” for grammatical purposes. In instant claim 12, the comma after chitosan should be removed for grammatical purposes. In instant claim 14, the second comma after “75:25” should be deleted for grammatical purposes. In instant claim 21, the term “further” should be inserted after “wherein the composition” for consistency purposes. Appropriate correction is required. Claim Rejections - 35 USC § 112 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. Claims 2-21 are 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. Claims 2-21 recite the limitation "The composition" in line 1 of each claim. There is insufficient antecedent basis for this limitation in the claim. Specifically, claims 2-21 should be amended to recite “The laundry treatment composition” to provide proper antecedent basis. Appropriate correction and/or clarification is required. Claim 2 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, for containing the limitation “excluding any solvent or other substances that may be mixed with the isocyanate”. This limitation renders the claim vague and indefinite, since the molecular weight of the isocyanate compound is based only on the elements present in the isocyanate compound. Accordingly, the limitation “excluding any solvent or other substances that may be mixed with the isocyanate” should be deleted. Appropriate correction and/or clarification is required. Claim 17 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, for being an improper multiple dependent claim. Appropriate correction and/or clarification is required. Claims 18-20 recite the limitation "wherein the treatment composition" in line 1 of each claim. There is insufficient antecedent basis for this limitation in the claim. Specifically, claims 18-20 should be amended to recite “wherein the laundry treatment composition” to provide proper antecedent basis. Appropriate correction and/or clarification is required. Claim 20 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, for containing the limitation “or a water-soluble non-woven” in line 3. This limitation renders the claim vague and indefinite, since it is unclear what is meant by a unitized dose being a “a water-soluble non-woven”. It appears that this limitation should be amended to recite “a water-soluble non-woven article”. Appropriate correction and/or clarification is required. Claim 21 recites the limitation "wherein the composition" in line 1. There is insufficient antecedent basis for this limitation in the claim. Specifically, claim 21 should be amended to recite “wherein the laundry treatment composition” to provide proper antecedent basis. Appropriate correction and/or clarification is required. Claim 21 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 applicant regards as the invention. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. In the present case, claim 21 recites the broad recitation “less than about 20%”, followed by the narrow recitation of “or even less than about 15%”. See MPEP 2173.05(c). Appropriate correction and/or clarification is required. Claim 21 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 applicant regards as the invention. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. In the present case, claim 21 recites the broad recitation “between about 15% and about 70%”, followed by the narrow recitation of “or even between about 20% and about 65%”. See MPEP 2173.05(c). Appropriate correction and/or clarification is required. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1-21 are rejected under 35 U.S.C. 103 as being unpatentable over Fernandez-Prieto et al, US 2023/0062702. Fernandez-Prieto et al, US 2023/0062702, discloses a fabric care composition comprising delivery particles that include a core/shell that is a polymeric material made by the reaction of a polyisocyanate and chitosan, wherein the core contains a fragrance (see abstract and paragraphs 10 and 55). It is further taught by Fernandez-Prieto et al that the polyisocyanate contains an aromatic moiety that contains at least two isocyanate groups, wherein suitable polyisocyanates include mixtures of toluene diisocyanate (i.e., an alpha-aromatic isocyanate) and a trimethylol propane-adduct of xylylene diisocyanate (i.e., a beta-aromatic isocyanate; see paragraphs 65-70), that the chitosan makes up 21-95% by weight of the shell (see paragraph 64), that the weight ratio of chitosan to isocyanate in the oil phase is 21:79 to 90:10 (see paragraph 64), that the fragrance is a perfume raw material having a log P of 2.5-4 (see paragraph 83), that the delivery particles have a median particle size of 1-100 microns (see paragraph 52), that the ratio of the core to the shell is up to 99:1 (see paragraph 53), that the fabric care composition further contains 0.1-70% by weight of a surfactant, such as anionic surfactants (see paragraphs 111-118), that the delivery particles are spray-dried (see paragraph 138), and that the fabric care composition is a liquid, gel or is in a unit dose form (see paragraphs 15 and 113), per the requirements of the instant invention. Specifically, note Examples 1-4 and Tables 1-3. Although Fernandez-Prieto et al generally discloses a fabric care composition containing a delivery particle shell comprising the reaction product of chitosan and a mixture of toluene diisocyanate (i.e., an alpha-aromatic isocyanate) and a trimethylol propane-adduct of xylylene diisocyanate (i.e., a beta-aromatic isocyanate), the reference does not require such fabric care compositions containing this delivery particle shell with sufficient specificity to constitute anticipation. It would have been obvious to a person of ordinary skill in the art at the time of the invention to have formulated a fabric care composition, as taught by Fernandez-Prieto et al, which contained a delivery particle shell comprising the reaction product of chitosan and a mixture of toluene diisocyanate and a trimethylol propane-adduct of xylylene diisocyanate, because such fabric care compositions fall within the scope of those taught by Fernandez-Prieto et al. Therefore, one of ordinary skill in the art would have had a reasonable expectation of success, because such a fabric care composition containing a delivery particle shell comprising the reaction product of chitosan and a mixture of toluene diisocyanate and a trimethylol propane-adduct of xylylene diisocyanate is expressly suggested by the Fernandez-Prieto et al disclosure and therefore is an obvious formulation. 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 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-18 of U.S. Patent No. 12,624,312. Although the claims at issue are not identical, they are not patentably distinct from each other because U.S. Patent No. 12,624,312 claims a similar liquid fabric care composition comprising a quaternary ammonium ester material, a surfactant, and a delivery particle comprising a fragrance core and a shell comprising the reaction product of chitosan and a mixture of toluene diisocyanate and a trimethylol propane-adduct of xylylene diisocyanate (see claims 1-18 of U.S. Patent No. 12,624,312), as required in the instant claims. Therefore, instant claims 1-21 are an obvious formulation in view of claims 1-18 of U.S. Patent No. 12,624,312. Claims 1-21 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-6 and 8-22 of copending Application No. 17/819,205 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because copending Application No. 17/819,205 claims a similar article of manufacture containing a delivery particle comprising a benefit agent core and a shell comprising the reaction product of chitosan and a mixture of toluene diisocyanate and a trimethylol propane-adduct of xylylene diisocyanate, and adjunct ingredients (see claims 1-6 and 8-22 of copending Application No. 17/819,205), as required in the instant claims. Therefore, instant claims 1-21 are an obvious formulation in view of claims 1-6 and 8-22 of copending Application No. 17/819,205. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-21 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of copending Application No. 18/978,202 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because copending Application No. 18/978,202 claims a similar composition comprising 25-99% by weight of a water-soluble carrier, a delivery particle comprising a perfume core and a shell comprising the reaction product of chitosan and a mixture of at least one alpha-aromatic isocyanate, such as toluene diisocyanate, and at least one beta-aromatic isocyanate, such as a trimethylol propane-adduct of xylylene diisocyanate, and adjunct ingredients (see claims 1-20 of copending Application No. 18/978,202), as required in the instant claims. Therefore, instant claims 1-21 are an obvious formulation in view of claims 1-20 of copending Application No. 18/978,202. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-21 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-17 of copending Application No. 18/969,361 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because copending Application No. 18/969,361 claims a similar water-soluble unit dose article comprising water, a non-encapsulated perfume, a delivery particle comprising a perfume core and a shell comprising the reaction product of chitosan and a mixture of at least one alpha-aromatic isocyanate, such as toluene diisocyanate, and at least one beta-aromatic isocyanate, such as a trimethylol propane-adduct of xylylene diisocyanate, and adjunct ingredients (see claims 1-17 of copending Application No. 18/969,361), as required in the instant claims. Therefore, instant claims 1-21 are an obvious formulation in view of claims 1-17 of copending Application No. 18/969,361. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-21 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-27 of copending Application No. 19/596,377 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because copending Application No. 19/596,377 claims a similar composition comprising a delivery particle comprising a perfume core and a shell comprising the reaction product of chitosan and a mixture of at least one alpha-aromatic isocyanate, such as toluene diisocyanate, and at least one beta-aromatic isocyanate, such as a trimethylol propane-adduct of xylylene diisocyanate, and adjunct ingredients (see claims 1-27 of copending Application No. 19/596,377), as required in the instant claims. Therefore, instant claims 1-21 are an obvious formulation in view of claims 1-27 of copending Application No. 19/596,377. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
