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 . Applicant’s arguments, filed 03/18/2026, have been fully considered. Rejections and/or objections not reiterated from previous office actions are hereby withdrawn. The following rejections and/or objections are either reiterated or newly applied. They constitute the complete set presently being applied to the instant application. Claim Status Claims 1-8, 10, and 12-15 are pending. Claim 15 is withdrawn. 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. Claims 1-8, 10, and 12-14, stand rejected under 35 U.S.C. 103 as being unpatentable over Bulbarello et al (WO 2019206984 A1, hereinafter “Bulbarello,” cited on IDS dated 07/19/2023), in view of MacDonald et al (US 20080311265 A1, hereinafter “MacDonald”). Bulbarello discloses a powderous composition comprising up to 70 wt% of at least one carotenoid and/or one carotenoid derivative, 5-30 wt% of at least one D-glycose oligomer (GO1) having a DE of <18, 5-30 wt% of at least one D-glycose oligomer (GO2) having a DE of >18, and 5-70 wt% of at least one polysaccharide (pg 1 ln 24-32). The at least one carotenoid and/or carotenoid derivative are alpha- or beta-carotene, 8'-apo-beta-carotenal, 8'-apо-beta-carotenoic acid esters such as the ethyl ester, cantaxanthin, astaxanthin, astaxanthin esters, lycopene, lutein, zeaxanthin or crocetin and their derivatives (pg 1 ln 7-9). The formulation comprises 0.1-70 wt% of the at least one carotenoid and/or carotenoid derivative (pg 2 ln 17-18). GO1 has a DE of preferably less than 15 (pg 3 ln 27-30). GO2 has a DE of preferably more than 20 (pg 4 ln 12-14). GO1 and GO2 can be used in the same amounts (1:1 mixture) (pg 4 ln 26-27). Preferably the polysaccharide is a modified starch, preferably the modified polysaccharide is starch sodium octenyl succinate (pg 4 ln 32, pg 5 ln 16). GO1 is preferably maltodextrin; GO2 is preferably maltodextrin (abs, pg 1 ln 24-32). Good flowability is desired for solid powderous formulations (pg 1 ln 11-13). Bulbarello does not specifically teach wherein the powderous composition further comprises at least 1 wt% of at least one water-soluble dietary fiber. MacDonald teaches powdered beverage compositions where it was known to include a water-soluble fiber to improve the flowability and cold-water solubility of the powdered compositions (abs, ¶ 6). The soluble fiber includes inulin, wheat dextrins, fructo-oligosaccharides, beta glycan and the like, etc., and mixtures thereof (¶ 15). The preferred soluble fiber is inulin (¶ 15). In embodiments, the soluble fiber is use in an amount of about 2-10 grams (¶¶ 5, 12). Regarding claim 1, Bulbarello discloses a powderous composition comprising up to 70wt% of at least one carotenoid and/or one carotenoid derivative, 5-30 wt% of at least one D-glycose oligomer (GO1) having a DE of <18, 5-30 wt% of at least one D-glycose oligomer (GO2) having a DE of >18, and 5-70 wt% of at least one polysaccharide. Regarding the water-soluble dietary fiber of claims 1 and 10, where Bulbarello discloses powder formulations where good flowability is desired, it would have been obvious to further include a water-soluble fiber known to improve the flowability and water solubility of powdered compositions, such as wheat dextrins, fructo-oligosaccharides, beta glycan, or the preferred inulin, as taught by MacDonald. Regarding the amount of dietary fiber of claim 1, it would have been obvious to include known amounts of water-soluble fiber that were known to be suitable for powdered compositions, such as from about 11 wt%, calculated the weight in grams of each component in paragraph [00012] of MacDonald. In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. See MPEP 2144.05(I). Further, it would have been well within the relative skills of the skilled artisan to routinely adjust the amount of water-soluble fiber in order to achieve optimal powder flowability properties. Generally, differences in concentration or temperature will not support the patentability of subject matter encompassed by the prior art unless there is evidence indicating such concentration or temperature is critical. Where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. See MPEP 2144(II)(A). Regarding claim 2, it would have been obvious to include at least one carotenoid and/or one carotenoid derivative selected from the group consisting of alpha- or beta-carotene, 8'-apo-beta-carotenal, 8'-apо-beta-carotenoic acid esters such as the ethyl ester, cantaxanthin, astaxanthin, astaxanthin esters, lycopene, lutein, zeaxanthin or crocetin and their derivatives, as taught by Bulbarello. Regarding claim 3, it would have been obvious to include 0.1-70 wt% of the at least one carotenoid and/or one carotenoid derivative, as taught by Bulbarello. Regarding claim 4, it would have been obvious to include GO1 with a DE of less than 15, which is taught to be preferable by Bulbarello. Regarding claim 5, it would have been obvious to include GO2 with a DE of more than 20, which is taught to be preferable by Bulbarello. Regarding claim 6, it would have been obvious to formulate the powderous composition with a GO1 to GO2 mixing ratio of 1:1, as taught by Bulbarello. Regarding claims 7 and 8, it would have been obvious to select from starch sodium octenyl succinate as the modified polysaccharide, as taught by Bulbarello. Regarding claim 12, it would have been obvious to select maltodextrin as the GO1 having a DE of <18, as taught by Bulbarello. Regarding claim 13, it would have been obvious to select maltodextrin as the GO2 having a DE of >18, as taught by Bulbarello. Regarding claim 14, it would have been obvious to select an ethyl ester of 8’-apo-beta-carotenoic acid as the at least one carotenoid and/or one carotenoid derivative, as taught by Bulbarello. Response to Arguments First, Applicants assert Bulbarello does not direct the skilled artisan to a solution as to how flowability could further be improved, and MacDonald seems to present a solution to a problem that Bulbarello does not raise. Applicants assert MacDonald provides protein containing powderous beverage compositions that have improved flowability due to the use of inulin as a water-soluble dietary fiber. Applicants assert the skilled artisan would not have a reasonable expectation of success that any flowability problem associated with the Bulbarello compositions could be solved by following the teachings of MacDonald, where Bulbarello teaches fat-soluble carotenoids and MacDonald teaches protein beverage compositions as different stabilizing systems/compounds that are required to make the compounds water-soluble. Second, Applicants assert MacDonald requires anticaking and flow agents in addition to the soluble fiber in the compositions, which Applicants assert MacDonald acknowledges are needed to further improve flowability. Thus, Applicants assert MacDonald does not unambiguously disclose that inulin or any other soluble fiber would serve to improve flowability alone in the protein compositions of MacDonald, let alone the fat-soluble compositions disclosed by Bulbarello. First, respectfully, this argument is not persuasive. Bulbarello teaches it is desirable to formulate powderous compositions that have good flowability, as would also be recognized by the skilled artisan, such as for ease of processing, handling, etc. When formulating a powderous composition where good flow is desirable, the skilled artisan would then turn to MacDonald, teaching powderous compositions with good flow, where it is explicitly taught that “the incorporation of the soluble fiber improves the flowability… the preferred soluble fiber is inulin…” (see ¶ 15 of MacDonald). While MacDonald may be directed to compositions comprising proteins, the broader teaching is that soluble fibers, including inulin, were known to improve the flowability of powderous compositions that can be used for the same purpose. Obviousness requires only a reasonable expectation of success, not absolute expectation of success; at least some degree of predictability is all that is required. The prior art can be modified or combined to reject claims as prima facie obvious as long as there is a reasonable expectation of success. See MPEP 2143.02. Following these teachings, the skilled artisan would have motivation to further include soluble fiber, including inulin, to the compositions of Bulbarello, with the reasonable expectation that their inclusion would improve the flowability of other powderous compositions that can be used for the same purpose. Second, respectfully, this argument is not persuasive. Applicants assert MacDonald requires anticaking and flow agents in addition to the soluble fiber in the compositions, however, anticaking agents and flow agents appear to be taught as optional components, where the anticaking and flow agents can be included in the compositions in an amount of 0 grams (see claim 9 of MacDonald). As discussed above, MacDonald explicitly teaches that soluble fibers, including inulin, are responsible for the improved flowability of the powderous compositions. Purely arguendo, even if anticaking and flow agents were required, the instant claims use the open language “comprising,” which does not exclude additional unrecited elements. Double Patenting - Withdrawn The nonstatutory double patenting rejections over the claims of copending application nos. 18/262,078 and 18/261,590 have been obviated by the filing and acceptance of a terminal disclaimer. Accordingly, the nonstatutory double patenting rejections are withdrawn. 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.
