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 .
The previous prior art rejection under Ninomya et al (JPH10265591) maintained and therefore it is proper to make this rejection FINAL.
Claim Objections
Claim 63 objected to because of the following informalities:
The cancelled formulas of diamines and dianhydrides should be properly crossed out.
In claim 63 some diamines are represented in both forms: as crossed out and actually claimed . For instance 1.2 and 1.3 phenylene diamines presented in both statuses.
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.
Claims 3, 61, 63-67 and 69 are rejected under 35 U.S.C. 103 as being unpatentable over
Ninomya et al (JPH10265591), cited in the previous Office Action.
The rejection can be found in the NON-FINAL office action mailed 10/20/2025 and is herein incorporated by reference.
Response to Arguments
Applicant's arguments filed 2/10/2026 have been fully considered but they are not persuasive.
Applicant submits that Ninomya’s polyamideimide is used as a sizing agent for a thermoplastic resin, while present claims drawn to a prepreg.
However, the Reference and Applicant use the same monomers for reactive oligomer preparation. It is clear that desirable properties can be achieved by monomers ratio and molecular weight variation.
Examiner agrees with Applicant that Yokota et al (JP 2004331801) does not teach polyamideimide
As a result, rejection under 35 USC 103 over Yokota et al (JP 2004331801) is withdrawn.
