Office Action

§102
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 . 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. Response to Amendment The Amendment filed 12/30/2025 has been entered. Claims 6-8 remain pending in the application. Claim Objections Claim 6 is objected to because of the following informalities: Claim 6 recites the limitations of "sealing the two pieces of glass are and fixing with glass adhesive". It is suggested that the word “are” be deleted to the recite “sealing the two pieces of glass and fixing with glass adhesive”. Appropriate correction is required. 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)(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) 6-8 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Qu (CN118164692A - see machine translation attached). Regarding claim 1, Qu discloses all the limitations of instant claim 1 as instantly recited (see claims 1-3 of Qu). Regarding claims 2-5, Qu discloses all the limitations of the instant claims 2-5 as instantly recited (see claims 4-5 of Qu). Response to Arguments Applicant's arguments filed 12/30/2025 have been fully considered but they are not persuasive. Applicant argues that the combination of claims 2-3 into claim 1 (now instant claim 6) renders claim 1 distinguishable from the prior art reference. The examiner disagrees. The combining of the limitations of claims 2-3 into claim (now instant claim 6) is disclosed by claims 1-3 of Qu. Conclusion 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.
