Office Action

§102
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 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. Claims 1-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Sato et al. (U.S. 12,410,332) Sato et al. discloses the following claimed subject matter: Re-claims 1-13, an aqueous inkjet ink comprising an aqueous vehicle, a pigment dispersion, a polymeric binder, and an additive (col.2, lines 9-18; col.9, line 40+); wherein said pigment dispersion comprising a self- dispersing pigment or a pigment dispersed by a polyurethane dispersant polymer (see col.4, lines 49-61; Resin Emulsion, col.8) or an acrylic dispersant polymer with alkaline neutralized carboxyl functional group , said polymeric binder (see Alkali-Soluble Resin, cols.3-4) is a polyurethane polymer or an acrylic polymer (Resin Emulsion, col.8), and said additive comprising a surface modified silanized colloidal silica particle, and is present at less than 3 wt%, based on the total weight of the ink (claim 1); and wherein the average particle size of said silica particle is smaller than 30 nm. (Levasil CC151, CC301; table 3; examples 21-26) Re-claim 2, wherein said surface modified silanized colloidal silica particle is the reaction product of a colloidal silica particle with an epoxy silane. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 3, wherein said pigment dispersion comprising a pigment dispersed by a polyurethane dispersant polymer with alkaline neutralized carboxyl functional group. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 4, wherein said polymeric binder is a polyurethane polymer. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 5, wherein said polymeric binder is an acrylic polymer. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 6, wherein said pigment dispersion comprising a pigment dispersed by an acrylic dispersant polymer with alkaline neutralized carboxyl functional group. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 7, wherein said polymeric binder is a polyurethane polymer. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 8, wherein said polymeric binder is an acrylic polymer. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 9, wherein said pigment dispersion comprising a self-dispersing pigment. (col.9, line 40+) Re-claim 10, wherein said polymeric binder is a polyurethane polymer. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 11, wherein said polymeric binder is an acrylic polymer. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Re-claim 12, wherein said ink does not comprise any free, surface un-modified, colloidal silica particles. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26; Colloidal Silica, col.7) Re-claim 13, wherein said polyurethane dispersant polymer and acrylic dispersant polymer are different from said polymeric binder. (see col.4, lines 49-61; Resin Emulsion, col.8. See also Alkali-Soluble Resin, cols.3-4; table 3; examples 21-26) Allowable Subject Matter Claims 14-18 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Pertinent Prior art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. WO 2022/176228 A1 to Sato et al.
