Office Action

§103
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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicants’ submission filed on 5/6/2026 has been entered. Response to Arguments All of Applicant’s argument filed 5/6/2026 have been fully considered. In view of the amendments to claim 1, the 103 rejection below has been modified below. Applicant argues that Example 3 showed superior effects as compared to Example 4 and comparative example 6. Applicant notes that the claims as amended are commensurate in scope with ingredients € and (G) as shown in tables 3-1 to 3-3. This is not persuasive as data is not commensurate in scope, as 1 single data point was provided and a single concentration point and a single pH (which determines how much tromethamine is present in the composition) is not sufficient to establish a trend in the data such that all species claims would have the stated effect. Applicant has not provided any evidence that the differences shown were statistically significant. Applicant has not provided any error bars, suggesting a single experiment which does not rise to the level of statistical significance and it’s unclear of the studies are reproducible. Applicant’s remarks regarding the oils of table 3-1 and 3-3 are not persuasive as the data shows these oils, for example phytostearyl/behenyl/octydodecyl lauroyl glutamate and stearoxy dimethicone, provide improved feel in use, however, these oils are known skin conditioning agents (see US 2019/0240134 [0021] and US2008/0159974, claim 7), as such as improved skin feel is expected. Regarding table 3-2, Applicant arguments are not persuasive as the examples do not comprise tromethamine as required by the instant claims, thus all examples in table 3-2 do not have a nexus to the claimed invention. Applicant argues that regarding the concentration ranges of adenosine phosphate and the other components, these ranges can be reasonably inferred from the working examples 1-16. These compounds and amounts used in the examples would be considered by a skilled artisan to be representative of the claimed compounds and amounts. The Examiner would also like to note that tables 3-1 to 3-2 focus on other effects (i.e. not odor or discoloration) and while Ex. 1-16 comprise the claimed compounds in various amounts, these examples do not demonstrate that the data of Ex. 3 is commensurate in scope with the claims as examples 1-16 do not test the effects (i.e. odor and discoloration), thus it’s unclear if these other embodiments show the same effects obtained in ex. 3. Modified/Maintained 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 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. Claim(s) 1-2, 5-6, 10, 12 and 14-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wakamatsu (US 2011/0112045), JP2014070063 and Harripersad (US 2008/0159974), as evidenced by Okubo (US 2012/0295989) and Okano (US 2008/0014231). Wakamatsu discloses an O/W emulsion comprising components (A) to (F) (Abs) for the production of a skin cosmetic (Wakamatsu – claims 9-10). The emulsions preferably have a viscosity ranging from 20,000 to 30,000 cps (equivalent to 20,000 to 30,000 mPas), this overlaps with the viscosity as recited by instant claims 1, 6 and 10 [0059]. Examples 1-8 of Wakamatsu disclose O/W emulsion with viscosities ranging from 15000-33000 comprising adenosine monophosphate, oils such as liquid paraffin, glycerin, acrylic acid-alkyl methacrylate copolymer, pH adjuster, purified water, etc. Regarding instant claims 1, 6 and 10, Ingredient (A): Wakamatsu teaches component (A) is an adenosine phosphate ester, preferred examples include adenosine monophosphate monosodium, adenosine monophosphate disodium, adenosine triphosphate monosodium, adenosine triphosphate disodium, adenosine triphosphate trisodium, and cyclic adenosine 3′,5′-monophosphate [0020]. This component is preferably used in amounts ranging from 0.5 to 7 wt. % [0022]. Regarding instant claims 1-2, 6 and 10, Ingredient (B): Wakamatsu teaches component (C) to be an acrylic acid-alkyl methacrylate copolymers which is preferably used in amounts ranging from 0.05-0.7wt%. [0027]. A preferred copolymers include Pemulen TR-1 and TR-2, selected from a finite number of options. As evidenced by Okubo, these polymers are acrylic acid/C10-30 alkyl acrylate crosspolymers having a molecular weight of 1,500,00 and 1,000,000 respectively (Table 1). Regarding instant claims 1, 6, 10 and 14, Ingredient (E): Wakamatsu teaches component (H) to be an oil and teaches that the oil used in not particularly limited. Suitable oils include jojoba oil, petrolatum, and silicone oils such as modified silicones which are modified by polyoxyethylene or polyoxypropylene [0040], The use of any of these oils is prima facie obvious and expected to yield no more than expected from such an arrangement. One or more oils are taught to be used in amounts of 5-40wt% [0041]. Regarding claim 15: Wakamatsu teaches the inclusion of Component (E), polyhydric alcohol(s), these are added to improve the expression of the emulsification property of the polyglycerin fatty acid ester, etc. A preferred polyhydric alcohol is glycerin, as evidenced by Okano, glycerin is a water-soluble humectant [0061]. Regarding instant claims 1 and 6: Ingredient (F): Wakamatsu teaches ingredient (G) to be water [0038]. Regarding instant claims 1, 5-6 and 10, Ingredient (D): Wakamatsu teaches that the composition is for external use and generally has a pH from mildly acidic to neutral, however, to reduce skin irritation and ensure a pigmentation prevention effect, the pH preferably ranges from 5.5-7. To adjust the pH of the composition, a pH adjuster may be added to the composition. Examples of pH adjusting agents include arginine, selected from a finite number of options. All of the working examples of Wakamatsu include a pH adjusting agent, thus the addition of a pH adjusting agent as taught is prima facia obvious. However, Wakamatsu does not teach ingredient (D), the pH adjuster, to be tromethamine. JP’063 teaches a skin external agent comprising water, oils, etc. and pH adjusting agents. JP’063 teaches that from the standpoint of good applicability to skin preferred pH adjusting agents are arginine and tromethamine (selected from a finite number of options) [0008, 0027 and 0026]. It would have been prima facie obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Wakamatsu with those of JP’063. One of skill in the art would have recognized arginine and tromethamine to be art recognized equivalent pH adjusting agents suitable for use in skin cosmetics. It would have been prima facie obvious to substitute arginine in the composition of Wakamatsu with tromethamine with a reasonable expectation of success. One of skill in the art would have a reasonable expectation of success because the simple substitution of one known element for another would have yielded predictable results to one of ordinary skill in the art at the time of the invention. As recognized by MPEP §2144.06, it is prima facie obvious to substitute art-recognized equivalents, and an express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). Regarding claim 12: The prior art makes obvious to use tromethamine as the sole pH adjuster as mixtures are not required by Wakamatsu, this reads on the composition not comprising a pH adjuster which is an inorganic alkali compound. However, Wakamatsu does not teach the oil component to further comprise an ingredient (G), such as stearoxy dimethicone, a silicone wax. Harripersad teaches cosmetic compositions for application to the skin (Abs). Harripersad teaches that skin conditioning agents such as stearoxy dimethicone, silica silylate and jojoba oil can be used (Harripersad – claim 6-7), and these are exemplified to be used in amounts of 0.01-50% (Harripersad – claim 19). It would have been prima facie obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of the above references with those of Harripersad. One of skill in the art would have been motivated to add 0.01-50% of a skin conditioning agent such as stearoxy dimethicone, selected from a finite number of options, to improve the skin conditioning properties of the composition of Wakamatsu. One of skill in the art would have a reasonable expectation of success as Wakamatsu teaches oils such as jojoba oil, which is a skin conditioning agent can be effect used. As discussed above, Wakamatsu makes obvious to use of ingredient (E) in amounts 5-40wt% [0041] and Harripersad makes obvious adding 0.01-50% of stearyl dimethicone (ingredient (G)), this provides amounts of ingredient (E) and ingredient (G) that overlap with the claimed ranges.
