Office Action

§101 §103 §DP
Response After RCE This Office action is in response to the RCE filed on 01/15/2026. Claims 1-20 are pending in the application. Claims 1-20 are rejected. Claims 1, 7, and 14 are currently amended. 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 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. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on January 15, 2026 has been entered. Response to Arguments The applicant's response filed January 15, 2026 has been fully considered and is respectfully found persuasive in part and unpersuasive in part. The following is at issue: [1] Prior art of record fails to teach newly admitted limitations [2] Amendments overcome double patenting rejection. [3] Prior art of record fails to teach previously presented Claim 1. Regarding [1], the examiner respectfully agrees and has applied new art that reads on the amendment. Regarding [2], the examiner respectfully disagrees because the newly admitted limitations have been previously claimed. The double patenting rejection stands. Regarding [3], the examiner respectfully disagrees because Sammoura teaches previously presented Claim 1 (see below). DETAILED ACTION Claim Rejections - 35 USC § 101 Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the "right to exclude" granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428,46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046,29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-11, 13, and 16-19 of U.S. Patent No. 11,224,895. Although the claims at issue are not identical, they are not patentably distinct from each other because claims 1-20 of 18/236879 are anticipated by claims 1-11, 13, and 16-19 of 11,224,895. Regarding claim 1, the current application (18/236879) is anticipated by claim 1 of 11,224,895.

Claim Rejections - 35 USC § 103 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 of this title, 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. Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Sammoura et al. (U.S. Publication No. 2017/0368574; hereinafter “Sammoura”) in view of Burbank et al. (U.S. Patent No. 6261241; hereinafter “Burbank”). Regarding claim 1, Sammoura teaches an ultrasound device comprising: an ultrasound transducer (Figs. 8-14; DEB pMUTs) comprising an annular ultrasound array (Figs. 8-14; Fig. 8; Fig. 11), wherein said annular ultrasound array (Figs. 8-14; Fig. 8; Fig. 11) comprises a plurality of concentric coplanar (Figs. 8-14; Fig. 8, 82-83) annular electrodes (Figs. 8-14; Fig. 8, 81-83) provided on a first surface (Figs. 8-14; Fig. 8, 81-83 sit on top surface) of a piezoelectric layer (Figs. 8-14; Fig. 8, active piezoelectric layer I/II), and wherein a ground plane electrode (Figs. 8-14; Fig. 8, 84; [0121]) is provided on a second surface (Figs. 8-14; Fig. 8, 84 sits on bottom surface) of said piezoelectric layer (Figs. 8-14; Fig. 8, active piezoelectric layer I/II); a peripheral support ring (Figs. 8-14; Fig. 8, ring of Si substrate and 86 delineating hole 85) surrounding (Fig. 8) at least a portion (Fig. 8) of said ultrasound transducer (Figs. 8-14; DEB pMUTs); and a flexible printed circuit board (Figs. 8-14; Fig. 11, B) comprising: an elongate flexible segment (Figs. 8-14; Fig. 8, Diaphragm; Fig. 11); and a distribution segment (Figs. 8-14; Fig. 11, segment in B connected to the transducers by the conductive paths); and a backing material (Figs. 8-14; Fig. 8, via; Fig. 11).

Burbank does not teach a distal portion that is bent away from a surface of the ultrasound transducer according to an angle of curvature. Burbank, however, does teach a distal portion (Fig. 3, 128) that is bent away (Fig. 3) from a surface (Fig. 3, surface of 102) of the ultrasound transducer (Fig. 3, 102) according to an angle of curvature (Fig. 3, angle of curvature of 128 in relation to surface of 102). It would have been obvious to one with ordinary skill in the art before the effective filing date of the claimed invention to have modified the device of Sammoura to include the distal portion of Burbank because it would enable a first tissue ablation element for electrosurgically separating tissue so as to create an incision thereby improving functionality (Burbank [Column 4, line 46-56]). Regarding claim 8, Sammoura as modified teaches the ultrasound device according to claim 7 further comprising wherein said elongate flexible segment (Figs. 8-14; Fig. 8, Diaphragm; Fig. 11) that is encapsulated (Fig. 8) within a backing material (Figs. 8-14; Fig. 8, via; Fig. 11).
