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
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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) 1-12 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CN 112300742 A to Kang et al. (hereinafter Kang), as evidenced by Adeka, “Low-chlorine epoxy resins,” https://www.adeka.co.jp/en/chemical/products/functional/pro143c.html, accessed 07/23/2026. (hereinafter Adeka).
Regarding claims 1-12, Kang teaches an epoxy resin adhesive material comprising component A and component B (See abstract), wherein component A contains 100 parts of a bisphenol A epoxy resin (E51), 13.9 parts of a side-chain epoxy resin (Adeka EP 4000), having the formula

, wherein n2 and n3 are integers and n2+n3 ≥ 2 (See Example 3, page 2 and 5), and 5.2 parts of a cashew phenol glycidyl ether diluent (See example 3, page 5), the cashew phenol glycidyl ether diluent having the formula

, wherein n4 is in the range of 0-3 (page 3). The above Adeka EP 4000 meets the epoxy compound, the above cashew phenol glycidyl ether meets the claimed cardanol-type epoxy compound, and the amounts correlates to a component A/B ratio of 72.8/27.2, which meets claims 1-3, 7-8. Kang further teaches component A is mixed with component B containing amines and cashew phenol, and a curing accelerator of 2,4,6-tri(dimethylaminomethyl)phenol (DMP-30), (See example 3, page 5), which meets the claimed amine curing agent. The components are mixed together and cured (See examples, page 4-7). The above Adeka EP 4000 also is known in the art to be a low chlorine epoxy resin that has a total chlorine amount of 0.01-.3% (i.e. 100-3000 ppm) as evidenced by Adeka.
