The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 102 3. 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. 4. 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. (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. 5. Claims 1-14 are rejected under 35 U.S.C. 102(a)(1) and rejected under 35 U.S.C. 102(a)(2) as being anticipated by (US 2019/0390061 A1) to Cheng et al. (hereinafter Cheng).

Cheng discloses at paragraph [0061] that a solvent is included. Cheng discloses at paragraph [0064] that a fiber is included. Cheng discloses each and every element of claims 1-14. Claim Rejections - 35 USC § 103 6. 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. 7. 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. 8. Claims 1-14 are rejected under 35 U.S.C. 103 as being unpatentable over (US 2019/0390061 A1) to Cheng et al. (hereinafter Cheng). Cheng is directed toward a crosslinked PPE composite. Cheng discloses at paragraph [0004] that a resin coating of 1.0 to 20.0 (100) parts by weight of a PPE resin with 1.0 (5) parts by weight of a crosslinkable monomer with a biphenyl group, which is adjusted to 100 parts resin reads Applicants range. Cheng discloses at paragraph [0006] that the crosslinkable monomer has the following formula: PNG media_image1.png 226 401 media_image1.png Greyscale Cheng discloses at paragraph [0010] that 0.001 to 0.05 by weight of a radical initiator. Cheng discloses at paragraph [0052] that Perbutyl-P is the initiator, which is a peroxide. Cheng discloses at paragraph [0063] that a filler is included. Cheng discloses at paragraph [0061] that a solvent is included. Cheng discloses at paragraph [0064] that a fiber is included. It would be obvious to one skilled in the art at the time of the filing of the disclosure of Cheng to select each and every element that forms a prime facie case of obviousness for claims 1-14.
