Office Action

§102
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 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) 46 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Cao et al (IEEE 3/20). The Cao et al reference teaches a two-dimensional stack, note entire reference. The grown layers can be graphene and boron nitride, note page 3. A water-soluble transfer stack comprising multilayer two-dimensional (2D) material, a transfer layer comprising a water-soluble polymer film, note page 2. Response to Applicants’ Arguments Applicant's arguments filed June 25, 2026 have been fully considered but they are not persuasive. The rejections over claims 26 to 45 have been overcome with the above response. However, newly submitted claim 46 stands rejected over new art. Applicant’s arguments with respect to claim(s) 46 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. Any inquiry concerning this communication or earlier communications from the examiner should be directed to ROBERT M KUNEMUND whose telephone number is (571)272-1464.
