Office Action

§102 §103
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 . DETAILED ACTION Claims 1-20 are pending. Note that, the amendment filed November 21, 2025, has been entered. Applicant's election with traverse of Group I, claims 1-17 and 20, in the reply filed on November 21, 2025, is acknowledged. The traversal is on the ground(s) that because Claims 1 and 18, the only independent claims in Groups I and II, respectively, both recite a composition containing a water-soluble polymer, a polysaccharide absorbent, water, a salt of the composition comprising the monocyclic triamine, and manganese(II) acetate. Additionally, Applicant states that there is no belief of a serious burden to search the claims as presented due to similarity or the nature of the application. This is not found persuasive because the invention of Group I, which is drawn to an uncoated or coated composition, is materially different and patentably distinct from the invention of Group II, wherein each Group would require a separate search due to their separate classification thereby placing an undue burden on the Examiner. The requirement is still deemed proper and is therefore made FINAL. Claims 18 and 19 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on November 21, 2025. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Claim Objections Claims 1-17 and 20 are objected to because of the following informalities: With respect to instant claim 1, line 3, it is suggested that Applicant delete “classes” and insert “group consisting”. With respect to instant claim 2, line 14, it is suggested that Applicant delete “and” and insert “or”. With respect to instant claim 2, line 17, it is suggested that Applicant delete “and” and insert “or”. With respect to instant claim 2, line 18, it is suggested that Applicant delete “and” and insert “or”. With respect to instant claim 2, line 20, it is suggested that Applicant delete “and” and insert “or”. With respect to instant claim 4, line 2, it is suggested that Applicant delete “and” and insert “or”. With respect to instant claim 8, line 3, it is suggested that Applicant delete “natural gum,” and insert “and natural gum”. With respect to instant claim 10, line 2, it is suggested that Applicant delete “or” and insert “and”. Note that, instant claims 3, 5-7, 9, 11-17, and 20 have also been objected to due to their dependency on claim 1. Appropriate correction is required. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 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. Claims 1-17 and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by WO2022/112177. With respect to independent, instant claim 1, ‘177 teaches a granule, that comprises a coating agent, a polysaccharide absorbent, 0.02-25 wt-% Mn(II) oxalate, and 0.1-25 wt-% of a salt which is the same as recited by the instant claims. See page 4. Examples of preferred compounds L used in the salt are 1 ,4, 7-triazacyclononanes, 1,4, 7-triaza­cyclododecanes, 1,4,8-triazacyclododecanes, 1,4,7-trimethyl-1,4,7-triazacyclo­nonanes and 1,4,7-trimethyl-1,4,7-triazacyclododecanes. See page 14. However, it may not be necessary to include a coating material, which is essential to prevent undesired degradation of the Mn(II) oxalate according to the first aspect of the invention, but which is not necessarily present in the granules according the second aspect of the invention. See page 16, lines 10-25. The coating agent, present in the granules of the first aspect of the invention and optionally present in the granules of the second aspect of the invention, comprises a water -soluble polymer, preferably polyvinyl alcohol or derivatives of polyvinyl alcohol. The coating material used in the granules of this invention may form a coating enveloping one or more of ingredients of the granules and/or may form a coating enveloping the granules. Preferably the granules of the invention are covered with a protective layer or coating. In another preferred embodiment the Mn(II) oxalate is covered with a coating. See page 18, lines 1-10. The granules according to the invention contain at least one polysaccharide absorbent which is present in amounts between 2 and 95 wt-%, preferably between 5 and 60 wt-% and most preferred between 10 and 50 wt-%, wherein the percentages refer to the total amount of the granule. See page 19, lines 25-35. Most suitable as processing additive is a starch, which is a polymer of glucose in which the glucopyranose units are bonded by a-linkages. Suitable sources of starch are potato starch, maize starch, rice starch, wheat starch and partially pregellatinised starches from the aforementioned list. Alternatively, the processing additive may be a modified starch, such as dextrin, a gum or alginate. Most suitably, the processing additive is maize starch, potato starch or rice starch. Also particularly suitable are cellulosic materials, such as cellulose fibers, methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, or carboxy-modified celluloses, such as carboxylmethyl cellulose (CMC). Most suitable is cellulose, in particularly microcrystalline cellulose (e.g. Heweten 101 ). See pages 20 and 21. The water-soluble polymer that may be included in the granules encompassing the monoprotonated, diprotonated or triprotonated cyclic triamine ligand salt according to the first or second aspect of the invention, includes poly(vinylpyrrolidones), polyalkylene glycols, functionalised poly(vinylalcohol)s and polyacrylates. The water-soluble polymer may be present in the coating and/or in the bulk of the granule. Examples of preferred polyvinyl alcohols or of modified polyvinyl alcohols are given above when disclosing preferred embodiments of the coating. These preferred (modified) polyvinyl alcohols can also be used in the bulk of the granule. In an embodiment, the granules comprise between 0.1 and 20 wt-% of the water-soluble polymer. See page 21, lines 15-30. In one embodiment the granule according to the invention contains at least one of the additional ingredients selected from the group consisting of a water­soluble polymer; a filler; a salt; and a bleach activator; and wherein these ingredients are present in the following amounts: 0-20 wt-% of a water-soluble polymer 0-85 wt-% of a filler; 0-85 wt-% of an inorganic salt; 0-90 wt-% of a bleach activator; wherein the percentages refer to the total amount of the granule. Additional manganese salts that may be use include Mn(ll)(acetate)2 , Mn(lll)(acetate)3, etc. See page 30, lines 1-25. The granules may be added to bleach compositions which may be used for automatic dishwashing. See pages 32-35. Specifically, ‘177 teaches a granule containing 2.43% by weight of Mn(II)di-(acetate), 2.43% by weight of a salt of formula [H2L](HSO4)2, 14.55% by weight of corn starch, 77.6% TAED, 3% by weight of polyvinyl alcohol which may be used as a coating. This granule is used in a automatic dishwashing composition containing sodium percarbonate, etc. See pages 43-45. ‘177 discloses the claimed invention with sufficient specificity to constitute anticipation. Accordingly, the teachings of ‘177 anticipate the material limitations of independent, instant claim 1 and the respective dependent claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Remaining references cited but not relied upon are considered to be cumulative to or less pertinent than those relied upon or discussed above. Applicant is reminded that any evidence to be presented in accordance with 37 CFR 1.131 or 1.132 should be submitted before final rejection in order to be considered timely.
