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.
Claims 6-9 are rejected under 35 U.S.C. 102 (a)(2) as anticipated by Ashraf et al. US 20240057004 A1 with priority of us-provisional-application US 63139476, hereinafter ‘ASHRAF’).
