Office Action

§112
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 . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the in regards to claim 3, “wherein the air cavity has a shape that is impacted by the first layer” (no figure shows a combination of two surface acoustic wave devices stacked on top of each other and wherein a first layer, which belong to the bottom/first acoustic wave device has a shape that impact an air cavity that is located above the top/second acoustic wave device) must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claim 3 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. In regards to claim 3, there is no support in the specification or drawings for the recited “wherein the air cavity has a shape that is impacted by the first layer” (the specification and figures do not teach/support having a combination of two surface acoustic wave devices stacked on top of each other, and wherein a first layer, which belong to the bottom/first acoustic wave device has a shape that impact an air cavity that is located above the top/second acoustic wave device), therefore the examiner has determined that such recitation is new matter. Allowable Subject Matter Claims 1, 2 and 4-20 are allowed. The following is a statement of reasons for the indication of allowable subject matter: Claims 11-20 are allowed for the reasons stated in the office action mailed on 5/29/2026. In regards to claim 1, the most relevant prior art reference is Hangzhou Sappland Microelectronics Tech Co LTD (CN109217841 A1, Reference of Record) as discussed in the office action mailed on 5/29/2026. However, the prior art does not teach: in regards to amended claim 1, a second surface acoustic wave device above the first layer, the second surface acoustic wave device including a second piezoelectric layer with a second interdigital transducer electrode that generate a second surface acoustic wave; a second layer above the second surface acoustic wave device, and wherein the bulk acoustic wave resonator is above the second layer. Therefore, the applicants’ claimed invention has been determined to be novel and non-obvious. By virtue of dependency from claim 1, claims 3-10 have also been determined to be novel and non-obvious. Response to Arguments Applicant’s arguments, see pages 6-8, filed on 8/27/2026, with respect to the rejections of record have been fully considered and are persuasive. Therefore, the rejections of record have been withdrawn. However, upon further consideration, a new ground of rejection has been made for claim 3 under 35 USC 112(b) which was necessitated by amendment. 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.
