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 . Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1-7 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-4 of copending Application No. 19/015476 (reference application). Although the conflicting claims are not identical, they are not patentably distinct from each other because the subject matter claimed in the instant application is disclosed in the co-pending application and is covered by the co-pending application since the co-pending application and the instant application are claiming common subject matter. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. 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. Claim(s) 1-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yoda et al. (# US 2022/0073772). Yoda et al. discloses: 1. An inkjet ink (see Abstract) comprising: a colorant (pigment: [0058]-[0073]); a binder resin ([0080]-[0081]; [0126]-[0129]); water ([0144]); and an organic solvent S ([0088]-[0097]), wherein the amount of the water is in a range from 3.0% by mass to 10.0% by mass, relative to the total amount of the ink (see Examples), the organic solvent S includes an organic solvent A with a boiling point of 150° C. or higher and lower than 200° C., in an amount of 90.0% by mass or more, relative to the total amount of the organic solvent S ([0088]-[0095]), and the organic solvent A includes a water-soluble organic solvent B with a boiling point of 150° C. or higher and lower than 200° C., in an amount of 50.0% by mass or more, relative to the total amount of the organic solvent S ([0092]). 2. The inkjet ink according to claim 1, wherein the water-soluble organic solvent B includes a water-soluble organic solvent Bx having a boiling point of 150° C. or higher and lower than 200° C ([0092]). 3. The inkjet ink according to claim 2, wherein the amount of the water-soluble organic solvent Bx is 75.0% by mass or more, relative to the total amount of the water-soluble organic solvent B (see Examples). 4. The inkjet ink according to claim 1, wherein the binder resin includes a (meth)acrylic resin ([0126]-[0128]). 5. An inkjet ink (see Abstract) comprising: a colorant (pigment: [0058]-[0073]); a binder resin ([0080]-[0081]; [0126]-[0129]); water ([0144]); and an organic solvent S ([0088]-[0097]), wherein the amount of the water is in a range from 3.0% by mass to 10.0% by mass, relative to the total amount of the ink (see Examples), the organic solvent S includes an organic solvent A with a boiling point of 150° C. or higher and lower than 200° C., in an amount of 90.0% by mass or more, relative to the total amount of the organic solvent S ([0088]-[0095]), and assuming that the amount of the water, relative to the total amount of the ink, is W % by mass, that a viscosity a (mPa.Math.s) is a viscosity at 23° C. of a mixture Ma of the organic solvent S and water in which a mass ratio between the organic solvent S and the water (organic solvent S:water) is 99:1, and that a viscosity b (mPa.Math.s) is a viscosity at 23° C. of a mixture Mb of the organic solvent S and water in which a mass ratio between the organic solvent S and the water (organic solvent S:water) is 100-W:W; then a ratio a/b between the viscosity a and the viscosity b is 0.95 or less (see Examples). 6. The inkjet ink according to claim 5, wherein the organic solvent A includes an organic solvent Ax having a boiling point of 150° C. or higher and lower than 200° C ([0088]-[0095]). 7. The inkjet ink according to claim 5, wherein the binder resin includes a (meth)acrylic resin ([0126]-[0128]). The Examiner draws particular attention to the Applicant that "Yoda et al. does address a colorant, binder resin, solvents and water, it teaches a laundry list of possible colorant, binder resin, solvents and water. The format in which Yoda et al. presents its teaching does not change the fact that it teaches the claimed invention. It is not necessary for Yoda et al. to present its teaching in an example format citing it in a list is sufficient. Therefore, it would have been obvious to one of ordinary skill in the art, absent evidence to the contrary, to choose any of the colorant, binder resin, solvents and water from the list and any additives from the list, including those presently claimed, and thereby arrive at the claimed invention. However, "applicant must look to the whole reference for what it teaches. Applicant cannot merely rely on the examples and argue that the reference did not teach others." In re Courtright, 377 Given that the Yoda et al. reference discloses a range of boiling point that overlap with the presently claimed range, it would have been obvious to one of ordinary skill in the art at the time of the invention to utilize any of the taught ranges, including those presently claimed, to obtain a suitable composition. It is also noted that according to MPEP 2131.03 and MPEP 2144.05, it would have been obvious to one of ordinary skill in the art at the time the invention was made to select the portion of the prior art's range which is within the range of applicant's claims because it has been held to be obvious to select a value in a known range by optimization for the best results. As to optimization results, a patent will not be granted based upon the optimization of result effective variables when the optimization is obtained through routine experimentation unless there is a showing of unexpected results which properly rebuts the prima facie case of obviousness. See In re Boesch, 617 F.2d 272, 276,205 USPQ 215, 219 (CCPA 1980). See also In re Woodruff, 919 F.2d 1575, 1578, 16 USPQ2d 1934, 1936-37 (Fed. Cir. 1990). In addition, a prima facie case of obviousness exists because the claimed ranges "overlap or lie inside ranges disclose by the prior art", see In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976; In re Woodruff, 919 F.2d 1575, 16USPQ2d 1934 (Fed. Cir. 1990) Yoda et al. explicitly did not discloses: 2. The inkjet ink according to claim 1, wherein the water-soluble organic solvent B includes a water-soluble organic solvent Bx having a Hansen solubility parameter (an HSP value) of 25.0 MPa1/2 or less. 6. The inkjet ink according to claim 5, wherein the organic solvent A includes an organic solvent Ax having a Hansen solubility parameter (an HSP value) of 25.0 MPa1/2 or less. However, Yoda et al. discloses exactly same organic solvent and A and organic solvent B as applicant discloses in their own specification. The solubility parameter is property of the material, which constant to the material. Therefore, the solvent discloses by the Yoda et al. obviously have the water-soluble organic solvent B includes a water-soluble organic solvent Bx having a Hansen solubility parameter (an HSP value) of 25.0 MPa1/2 or less & the organic solvent A includes an organic solvent Ax having a Hansen solubility parameter (an HSP value) of 25.0 MPa1/2 or less. Claim(s) 8-11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yoda et al. (# US 2022/0073772) in view of Urano et al. (# US 2020/0276850). Yoda et al. discloses; 8. An inkjet ink set comprising the inkjet ink according to claim 1 (see Examples). 10. An inkjet ink set comprising the inkjet ink according to claim 5 (see Examples). Yoda et al. explicitly did not discloses: 8. An inkjet ink set comprising a pretreatment liquid including an aggregating agent, and water in an amount of more than 10.0% by mass, relative to the total amount of the pretreatment liquid. 9. The inkjet ink set according to claim 8, wherein the aggregating agent includes at least one selected from the group consisting of a polyvalent metal salt and a cationic water-soluble resin. 10. An inkjet ink set comprising a pretreatment liquid including an aggregating agent, and water in an amount of more than 10.0% by mass, relative to the total amount of the pretreatment liquid. 11. The inkjet ink set according to claim 10, wherein the aggregating agent includes at least one selected from the group consisting of a polyvalent metal salt and a cationic water-soluble resin. Urano et al. teaches the to have a high quality bleed free printed image, 8. An inkjet ink set comprising a pretreatment liquid including an aggregating agent, and water in an amount of more than 10.0% by mass, relative to the total amount of the pretreatment liquid ([0044]-[0051]; see Examples). 9. The inkjet ink set according to claim 8, wherein the aggregating agent includes at least one selected from the group consisting of a polyvalent metal salt ([0044]-[0048]) and a cationic water-soluble resin ([0049]-[0051]). 10. An inkjet ink set comprising a pretreatment liquid including an aggregating agent, and water in an amount of more than 10.0% by mass, relative to the total amount of the pretreatment liquid ([0044]-[0051]; see Examples). 11. The inkjet ink set according to claim 10, wherein the aggregating agent includes at least one selected from the group consisting of a polyvalent metal salt ([0044]-[0048]) and a cationic water-soluble resin ([0049]-[0051]). It would have been obvious to one of ordinary skill in the art before the effective filling date of the invention to incorporate the pretreatment liquid of Urano et al. to the ink composition and printing method of Yoda et al. in order to have the bleed free high quality printed image. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. (1) Tsuru et al.
