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 .
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)(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(s) 1-8 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Mizuguchi et al (US 2024/0182644, effective filing date 3/30/2021).
The applied reference has a common inventor(s) with the instant application. Based upon the earlier effectively filed date of the reference, it constitutes prior art under 35 U.S.C. 102(a)(2). This rejection under 35 U.S.C. 102(a)(2) might be overcome by: (1) a showing under 37 CFR 1.130(a) that the subject matter disclosed in the reference was obtained directly or indirectly from the inventor or a joint inventor of this application and is thus not prior art in accordance with 35 U.S.C. 102(b)(2)(A); (2) a showing under 37 CFR 1.130(b) of a prior public disclosure under 35 U.S.C. 102(b)(2)(B) if the same invention is not being claimed; or (3) a statement pursuant to 35 U.S.C. 102(b)(2)(C) establishing that, not later than the effective filing date of the claimed invention, the subject matter disclosed in the reference and the claimed invention were either owned by the same person or subject to an obligation of assignment to the same person or subject to a joint research agreement.
Mizuguchi sets forth curable resin compositions and cured objects obtained therefrom. Said resin composition comprises 30 wt. % to 95 wt. % of (A) a maleimide resin obtained from a diamine (a-1) derived from a dimer acid, a tetracarboxylic acid dianhydride (a-2) and maleic anhydride represented by the general formula:

as defined in sections [0097]-[0111]; from 3 wt. % to 60 wt. % of (B) a maleimide resin represented by formula (1):

; from 0.1 parts by mass to 10 parts by mass of (D) a curing accelerator, wherein (A), (B) and (D) are compatible with one another—see abstract, [0018]-[0022];[0058]-[0059];[0113]-[0151]; [0227] and [0216]-[0232].
Said composition additionally comprises (C) a thermosetting resin selected from one or more from the group selected from a maleimide compound other than the component (A) and the component (B), a cyanate ester compound, a phenolic resin, an epoxy resin, an oxetane resin, a benzoxazine compound, a carbodiimide compound, and a compound containing an ethylenically unsaturated group— [0042]- [0047]. Said thermosetting resin (C) is blended in amounts from 1 to 10 times the total amount of the maleimide resins (A) and (B) in terms of weight ratios—see [0147]. Additionally, the composition comprises a photoinitiator, wherein Mizuguchi sets forth preferred photoinitiators have oxime structures—see [0232].
Regarding claim 1: Mizuguchi explicitly sets forth a composition comprising 46 parts of (A-1) a maleimide resin being the reaction product Priamine 1074 (a diamine derived from a dimer acid); methanesulfonic anhydride and 1,2,3,4-cyclohexane tetracarboxylic acid with maleic anhydride; 8 parts of (B-1) a maleimide resin represented by formula (10):

; 42 parts of thermosetting resin (C-2) which is the reaction product an epoxy carboxylate resin obtained by the reaction of an epoxy resin compound having the general formula:

and acrylic acid with the polybasic acid anhydride: 1,2,3,6-tetrahydrophthalic anhydride; 1 part by weight of curing agent (D-1): dicumyl peroxide; 0.5 parts by mass of photoinitiator: OXE-02 (an oxime compound); and 34 parts of an organic solvent—see example 4 in Table 4 on page 30; [0303]; [0320]-[0321]; and [0326]. It is deemed (A-1), in example 1, anticipates applicants claimed maleimide (I); the (B-1) and in example 1, anticipates applicants claimed reactive polycarboxylic resin (II).
Regarding claims 2-+3: the maleimide resin (A-1), in example 1, is the reaction product of Priamine 1074 (a diamine derived from a dimer acid) which anticipated (a-1) in claims 1-2; methanesulfonic anhydride and 1,2,3,4-cyclohexane tetracarboxylic acid which corresponds to (a-2) the polybasic acid anhydride having an alicyclic structure in claims 2-3 with maleic anhydride.
Regarding claim 4: Mizuguchi sets forth the maleimide resin (A) obtained from a diamine (a-1) derived from a dimer acid, a tetracarboxylic acid dianhydride (a-2) and maleic anhydride is represented by the general formula:

as defined in sections [0097]- [0111].
Regarding claim 5: The epoxy carboxylate resin is obtained by the reaction of an epoxy resin compound having the general formula:

and acrylic acid with the polybasic acid anhydride: 1,2,3,6-tetrahydrophthalic anhydride. The epoxy resin having the above structure corresponds to formula (2) when R6 is a C10 alicyclic skeleton, R7 is H and x is 2.5.
Regarding claim 6: The oxe-02 in example 4 is a photoinitiator having an oxime structure.
Regarding claim 7: It is deemed the cured product of the composition found in example 4 anticipates the cured product found in claim 7.
Regarding claim 8: Mizuguchi sets forth the curable compositions found in the examples, i.e., example 4 is coated onto an imide base substrate and coved with fluoroelastomer (Aflex) to obtain a multilayered material—see [0379]. Thus, claim 8 is anticipated by the reference.
