DETAILED ACTION
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Election/Restrictions
Applicant’s election with traverse of Group 1, Claims 1-4, 7, 9-12, 13-16, 19, 23-24, species of the only polymers are polymeric colorant and the acid functional polymer and of the acid functional polymer, filed on 5/21/2026 is acknowledged.
In response to applicant's argument regarding the unity of invention, it is noted that 1) common technical feature is not a necessary a special technical feature; 2) there is no subject matter common to all claims.
In response to applicant's argument the identified ink species are not patentably distinct and do not require separate examination, this is not found persuasive because the issue as to the meaning and intent regarding “independent and distinct” as used in 35 U.S.C 121 and 37 CFR 1.41, which is for national applications, but it is not used for PCT national stage (371) applications. For PCT national stage applications, restriction is based upon unity of invention; restriction of a national stage application does not take into account whether or not the inventions are independent or distinct, and does not take into account burden on the examiner.
In response to applicant's argument that acid polymer and its salt are functionally equivalent and share the same polymer backbone. If applicant admits they are the same and one can read on the other, then the species election requirement would be withdrawn.
Therefore, the restriction requirement based on the lack of unity analysis is still deemed proper and is made final. Accordingly, claims 9-12, 14-16, 19, 23-24, 29-32, 40 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention and species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 5/21/2026.
Specification
Applicant is reminded of the proper language and format for an abstract of the disclosure.
The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words. It is important that the abstract not exceed 150 words in length since the space provided for the abstract on the computer tape used by the printer is limited. The form and legal phraseology often used in patent claims, such as "means" and "said," should be avoided. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details.
The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, "The disclosure concerns," "The disclosure defined by this invention," "The disclosure describes," etc.
The abstract of the disclosure is objected to because it contains less than 50 words. Correction is required. See MPEP § 608.01(b).
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 1-4, 7 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 pre-AIA the applicant regards as the invention.
Claim 1 recites “solution soluble polymeric colorant”, what does “solution soluble” mean? For purposes of expediting prosecution, any polymeric colorant would meet the limitation.
Claim 2 recites “one or more acid functional polymers… salts thereof”. Salts of acid functional polymers are no longer acid functional polymers. Clarification is required.
The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph:
Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
Claims 2, 4 rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends.
Claim 2 broadens the scope of claim 1.
Claim 4 does not further limit claim 3.
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.
Claim(s) 2-4, 7 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by over Nagai et al (US 5,879,439).
Nagai teaches an ink composition comprising a polymeric dye, a styrene-acrylic acid polymer dispersant, a surfactant, water and organic solvents (example 1-3). The nonionic surfactant polyoxyethylene alkylphenyl ether is an oligomer instead of a polymer.
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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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.
Claim 1-4, 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Nagai et al (US 5,879,439).
Nagai teaches an ink composition comprising a polymeric dye, a dispersant such as styrene-maleic acid resin, a surfactant, water and an organic solvent (abstract, 15:10). The polymeric dye are those listed in table 1. The nonionic surfactant polyoxyethylene alkylphenyl ether is an oligomer instead of a polymer.
