Office Action

§112
CTNF 18/579,147 CTNF 85809 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 08-25 AIA Applicant's election with traverse of Group I, claims 1-7 and 16-19 in the reply filed on 04/17/2026 is acknowledged. The traversal is on the ground(s) that the international PCT application did not dispute the unity of the invention . This is not found persuasive because examination under US practice is independent from that of the international authority. That is, there is nothing that requires that the USPTO must defer to the International Searching Authority. Further, it is noted that MPEP 1850 II states that lack of unity of invention may be directly evident "a priori," that is, before considering the claims in relation to any prior art, or may only become apparent "a posteriori," that is, after taking the prior art into consideration. As set forth in paragraph 4 of the previous Office Action mailed 03/24/2026, the Examiner has shown that the present invention does not make a contribution over the prior art, i.e. has shown there is a lack of unity "a posteriori" and therefore, the restriction requirement is proper . The requirement is still deemed proper and is therefore made FINAL. 08-05 AIA Claim s 8, 15 and 20 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention , there being no allowable generic or linking claim.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 04/17/2026 . Claim Objections 07-29-01 AIA Claim 19 is objected to because of the following informalities: Claim 19 recites “a primer coating”. It is suggested the claim is amended to recite “the primer coating” . Appropriate correction is required. Claim 19 recites “a substrate”. It is suggested the claim is amended to recite “the substrate”. Appropriate correction is required. Claim Rejections - 35 USC § 112 07-30-02 AIA 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. 07-34-01 Claims 1-7 and 16-19 are 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. Claim 1 recites the phrase “namely” line 7 which is confusing given that it is not clear whether the at least two kinds of pigments being different from one another are required to be the at least one organic black or inorganic black pigment and at least one inorganic white pigment. That is, the at least one organic black or inorganic black pigment and at least one inorganic white pigment are not positively recited. Claims 2-7 and 16-19 all depend from claim 1 and thus, are also rendered indefinite. Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Richter et al. (US2011/0070455) teaches a coating comprising coating composition B comprising at least one black pigment with low NIR absorption and at least one further pigment (paragraph [0051]), wherein the further pigment may be white, colored or other black pigments that differ from the black pigment with low NIR absorption (paragraph [0056]), and wherein the coating exhibits a brightness L* of at most 10 (paragraph [0051]). The coating further comprises one or more binders, one or more crosslinkers, and one or more paste resins or polymeric pigment wetting or dispersion aids (paragraph [0050]), which may correspond to at least one constituent P-A. The coating is also a solvent- or waterborne coating (paragraph [0064]). However, Richter et al. fails to teach pigment P=C1 in an amount as presently claimed .
