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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 11/13/2025 has been entered.
Response to Amendment
The amendment of claims 1, 3 are supported by the specification.
Any rejections and/or objections made in the previous Office action and not repeated below are hereby withdrawn.
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Claim Rejections - 35 USC § 103
Claims 1-3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hosoda et al (WO2019163913) in view of Tomihashi et al (JP2003053261).
In setting forth this rejection a machine translation of JP2003053261 has been relied upon and all citations to paragraph numbers in the discussion below are with respect to the machine translation.
Hosoda teaches a powder coating composition comprising 95vol% of a fluororesin powder X and 5 vol% of a resin powder Y [0266-0284, example 10]. The fluororesin powder X is NAH/TFE/PPVE copolymer with D50 of 22.08um and s specific gravity of 2.13. The resin powder Y-2 has a D50 of 20um and a specific gravity of 1.3. Therefore the average particle size of the resin powder falls within the claimed range. Hosoda further teaches the composition can include a heat stabilizer [0072].
Hosoda does not teach the content nor the type of the heat stabilizer.
However, Tomihashi teaches a heat stabilizer for fluororesin can be an aromatic amine compound such as N,N'-di-2-naphthyl-p-phenylenediamine in an amount of 0.001-5wt% based on the weight of the fluororesin [0051, examples]. Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to utilize an aromatic amine compound heat stabilizer for the composition of Hosoda because it is recognized in the art a suitable heat stabilizer for fluororesin.
