Office Action

§102 §103 §112
Response to Amendment 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 claims are interpreted as a detergent and method of using the same comprising hydroxyl compound a1-a8 in proportions; or tropolone and components a1-a9 and method of using the same with the additional water immiscible component or fragrance. 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 4, 8, 12 and 13 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 is withdraw. Claim Objections Claims 1, 2, 8, 12 and 13 objected to because of the following informalities: The aforementioned claims state “amounts from 0.001 to about 2,0 wt. percent” or “0.005 to 1,55 wt. percent” is withdrawn. 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. 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, 2-7 is/are rejected under 35 U.S.C. 102(a1) as being anticipated by Schmaus et al (2010/0196504) is withdrawn. Claim(s) 8, 12 and 13 is/are rejected under 35 U.S.C. 102(a1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Schmaus et al ((2010/0196504) is withdrawn. Claim(s) 1-8, 12-13, 20-21 is/are rejected under 35 U.S.C. 103 as being unpatentable over AU 2019434303. AU ‘303 discloses an antimicrobial mixture comprising or consisting of (a) at least one monocyclic sesquiterpene alcohol, (b) at least one active selected from the group consisting of 4-hydroxyacetophenone, sorbitan caprylate, cocamidopropyl PG-dimonium chloride phosphate, tetrasodium glutamate diacetate, glyceryl caprylate and glyceryl caprate, and optionally (c) at least one additional antimicrobial agent different from components (a) and (b) (abstract). AU ‘303 teaches alkanediol are included selected from the group consisting of 1,2-propandiol, 1,3-propandiol, 1,2-butandiol, 1,2-pentandiol, 1,2-hexandiol, 1,2-heptandiol, 1,2-octandiol, 1,2-nonandiol, 1,2-decandiol and their mixtures (0034). AU teaches that said composition may be used in detergent formulations and include surfactants such as betaines and alkylpolyglycosides (0042 and 0127). See claim were comprising a composition of A-C where component B is a glyceryl caprylate and A:B are in a ratio of 10:90 and 90:10; component C is an additional antimicrobial agent which may encompass a tropolone (claim 7) in an amount from 0-99% (claim 8) and additional 1,2 alkanediols having 5-12 carbons are employed (claim 5). AU ‘303 do not teach with sufficient specificity to anticipate the claims, but one skilled in the art would have been motivated to combine the known ingredients used in detergent compositions in their requisite proportions in light of the teachings of AU ‘303. In the absence of a showing to the contrary, one skilled would expect similar characteristics from optimizing the amounts and ratios as claimed to determine the optimum cleansing compositions. “The normal desire of scientists or artisans to improve upon what is already generally known provides the motivation to determine where in a disclosed set of percentage ranges is the optimum combination of percentages” Peterson, 315 F.3d at 1330, 65 USPQ2d at 1382; In re Hoeschele, 406 F.2d 1403, 160 USPQ 809 (CCPA 1969) Merck & Co. Inc. v. Biocraft Laboratories Inc., 874 F.2d 804, 10 USPQ2d 1843 (Fed. Cir.), cert. denied, 493 U.S. 975 (1989); In re Kulling, 897 F.2d 1147, 14 USPQ2d 1056 (Fed. Cir. 1990); and In re Geisler, 116 F.3d 1465, 43 USPQ2d 1362 (Fed. Cir. 1997).“[T]he discovery of a previously unappreciated property of a prior art composition, or of a scientific explanation for the prior art’s functioning, does not render the old composition patentably new to the discoverer.” Atlas Powder Co. v. Ireco Inc., 190 F.3d 1342, 1347, 51 USPQ2d 1943, 1947 (Fed. Cir. 1999). Thus, the claiming of a new use, new function or unknown property, which is inherently present in the prior art does not necessarily make the claim patentable. In re Best, 562 F.2d 1252, 1254, 195 USPQ 430, 433 (CCPA 1977). [W]hen a patent 'simply arranges old elements with each performing the same function it had known to perform' and yields no more than one would expect from such an arrangement, the combination is obvious. [KSR Int'l Co. v.Teleflex Inc., 550 U.S. at 418 (quoting Sakraida v. Ag Pro, Inc., 425 U.S. 273,282 (1976).] Applicant’s arguments with respect to claim(s) have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicants’ amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
