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 . Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Election/Restrictions Applicant’s election without traverse of Group I drawn to a cosmetic composition in the reply filed on 15 December 2025 is acknowledged. Claims 17-20 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 15 December 2025. Applicant’s election without traverse of caprylyl/capryl glucoside as the species of nonionic surfactant; a mixture of heterocyclic coupling agents and m-aminophenol as the species of additional oxidation coupler; para-phenylenediamines as the species of oxidation base; mixtures of liquid hydrocarbons containing more than 16 carbon atoms, plant oils, and fatty alcohols as the species of fatty substance; steareth-20 as the species of additional nonionic surfactant; EDTA as the species of sequestrant agent; alkanolamines for the species of alkaline agent; and hydrogen peroxide for the species of chemical oxidizing agent in the reply filed on 15 December 2025 is acknowledged. Claim 12 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 15 December 2025. Claims 1-11 and 13-16 are examined on the merits herein. Claim Objections Claims 8, 10-11, and 13-15 objected to because of the following informalities: the term “further” should be recited immediately prior to the term “comprising”. 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 2-11, 13, and 15-16 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. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claims 2-11, 13, and 15-16 recite broad limitations, followed by the phrases “preferably”, “preferentially”, “more preferentially”, “better still”, “even better still”, and “such as” followed by narrower limitations. The claims are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. For examination purposes, the narrower language is interpreted as being merely exemplary of the remainder of the claim. Claim Rejections - 35 USC § 103 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-11, 13, and 15-16 are rejected under 35 U.S.C. 103 as being unpatentable over Nicou et al. (WO 2017/108840) in view of Agostino et al. (US 2013/0220358). Claim 1 is drawn to a cosmetic composition comprising: at least one oxidation coupler chosen from 6-hydroxybenzomorpholine, its addition salts, its solvates, and/or solvates of its salts; at least one oxidation coupler chosen from hydroxyethyl-3,4-methylenedioxyaniline, its addition salts, its solvates, and/or solvates of its salts; one or more nonionic surfactants of alkylpolyglycoside type (more specifically caprylyl/capryl glucoside (claim 6, Applicant’s elected species). Nicou et al. teach compositions for dying hair comprising oxidation couplers (Abstract) including formula 1 (pgs. 26-27) comprising: hydroxybenzomorpholine; -; and caprylyl/capryl glucoside, further teaching the use of 6-hydroxybenzomorpholine as the oxidation coupler (Pg. 5 lines 7-8). The composition of Nicou et al. differs from the instantly claimed composition in the following ways: the composition of Nicou et al. does not comprise hydroxyethyl-3,4,-methylenedioxyaniline. Yet, as to 1: Nicou et al. further teach that the composition can comprise additional couplers (Pg. 5 lines 1-6). Agostino et al. teach similar hair dying compositions (Abstract) comprising oxidation couplers (Par. [0031]) including 6-hydroxybenzomorpholine and hydroxyethyl-3,4-methylenedioxyaniline (Par. [0033]). And as discussed in MPEP 2144.06, “It is prima facie obvious to combine two compositions each of which is taught by the prior art to be useful for the same purpose, in order to form a third composition to be used for the very same purpose… [T]he idea of combining them flows logically from their having been individually taught in the prior art.” In re Kerkhoven, 626 F.2d 846, 850, 205 USPQ 1069, 1072 (CCPA 1980). In the instant case, as both 6-hydroxybenzomorpholine and hydroxyethyl-3,4-methylenedioxyaniline are known in the prior art as oxidation couplers suitable for use in hair dyes, it would have been prima facie obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified the composition of Nicou et al. to include hydroxyethyl-3,4-methylenedioxyaniline. It would have been obvious to combine the two oxidation couplers to yield a composition further capable of acting as an oxidation coupler in a hair dye, with a reasonable expectation of success. Based on all of the foregoing, claims 1 and 6 are rejected as prima facie obvious. Claim 2 is drawn to the composition of claim 1, wherein the 6-hydroxybenzomorpholine is present in a total content ranging from 0.001% to 20% by weight, relative to the weight of the composition. Claim 3 is drawn to the composition of claim 1, wherein the hydroxyethyl-3,4-methylenedioxyaniline is present in a total content ranging from 0.001% to 20% by weight, relative to the weight of the composition. Claim 4 is drawn to the composition of claim 1, wherein the total amount of 6-hydroxybenzomorpholine and hydroxyethyl-3,4-methylenedioxyaniline is present in a total content ranging from 0.001% to 20% by weight, relative to the weight of the composition. Nicou et al. further teach formula 1 comprising 0.006% 6-hydroxybenzomorpholine (pg. 26), overlapping with the instantly claimed range. Additionally, Nicou et al. teach the total amount of couplers ranging from 0.0001% to 20% by weight relative to the total weight of the composition (Pg. 5 lines 28-31), overlapping with the instantly claimed range and indicating that the amount of hydroxyethyl-3,4-methylenedioxyaniline would necessarily fall into the instantly claimed range. As such, claims 2-4 are rejected as prima facie obvious. Claim 5 is drawn to the composition of claim 1, further comprising one or more additional oxidation couplers, more specifically a mixture of heterocyclic coupling agents and m-aminophenol (Applicant’s elected species). Nicou et al. further teach formula 1 comprising additional oxidation couplers including m-aminophenol, resorcinol, 4-amino-m-cresol, and p-aminophenol (pg. 26). Nicou et al. do not teach the formula 1 comprising heterocyclic coupling agents. However, Nicou et al. further teach the use of oxidation couplers including hydroxyindole, 2-amino-3-hydroxypyridine, and 3-methyl-1-phenyl 5-pyrazolone (Pg. 5 lines 7-22), i.e., heterocyclic coupling agents. Therefore, it would have been prima facie obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified the composition of Nicou et al. to include a heterocyclic coupling agent. It would have been obvious to substitute one oxidation coupling agent suitable for use in a hair dye for another to obtain the predictable result of a hair dye composition, with a reasonable expectation of success. As such, claim 5 is rejected as prima facie obvious. Claim 7 is drawn to the composition of claim 1, wherein the total content of the alkylpolyglycoside ranges from 0.05% to 15% by weight, relative to the weight of the composition. Nicou et al. further teach formula 1 comprising 2.4% caprylyl/capryl glucoside (pg. 27), overlapping with the instantly claimed range. As such, claim 7 is rejected as prima facie obvious. Claim 8 is drawn to the composition of claim 1, further comprising an oxidation base, more specifically a para-phenyldiamine (Applicant’s elected species). Claim 9 is drawn to the composition of claim 8, wherein the oxidation base is present in an amount ranging from 0.001% to 20% by weight, relative to the weight of the composition. Nicou et al. further teach formula 1 comprising 0.6% 3-(2,5-diaminophenyl)-1-propanol (pg. 27), i.e., a para-phenyldiamine compound. Nicou et al. additionally teach 3-(2,5-diaminophenyl)-1-propanol as an oxidation base (Pg. 4 lines 17-20). As such, claims 8-9 are rejected as prima facie obvious. Claim 10 is drawn to the composition of claim 1, further comprising at least one fatty substance. Claim 11 is drawn to the composition of claim 1, comprising at least one liquid fatty substance, more specifically mixtures of liquid hydrocarbons containing more than 16 carbon atoms, plant oils, and fatty alcohols (Applicant’s elected species). Nicou et al. further teach formula 1 comprising mineral oil (pg. 27) i.e., a liquid fatty substance. Nicou et al. further teach liquid fatty substances including liquid hydrocarbons comprising more than 16 carbon atoms, plant oils, and liquid fatty alcohols (pg. 19 lines 21-25). As such, claims 10-11 are rejected as prima facie obvious. Claim 13 is drawn to the composition of claim 1, further comprising an additional surfactant, more specifically the nonionic surfactant steareth-20 (Applicant’s elected species). Nicou et al. further teach formula 1 comprising steareth-20 (Pg. 27). As such, claim 13 is rejected as prima facie obvious. Claim 14 is drawn to the composition of claim 1, further comprising one or more sequestrants, more specifically EDTA (Applicant’s elected species). Nicou et al. further teach formula 1 comprising EDTA (pg. 26). As such, claim 14 is rejected as prima facie obvious. Claim 15 is drawn to the composition of claim 1, further comprising at least one alkaline agent, more specifically an alkanolamine (Applicant’s elected species). Nicou et al. further teach formula 1 comprising ethanolamine (Pg. 26). As such, claim 15 is rejected as prima facie obvious. Claim 16 is drawn to the composition of claim 1, further comprising one or more chemical oxidizing agents, more specifically hydrogen peroxide (Applicant’s elected species). Nicou et al. further teach combining formula 1 with oxidizing formula Ox1, which comprises hydrogen peroxide (pg. 27). As such, claim 16 is rejected as prima facie obvious. 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.
