Response to Amendment This office action is responsive to the amendment filed on 5/1/2026. As directed by the amendment: claim(s) 1, 6, 11, and 15-16 have been amended. Thus, claims 1-20 are presently pending in this application. Response to Arguments Applicant's arguments filed 5/1/2026 have been fully considered but they are not fully persuasive. Regarding applicant’s argument regarding the independent claims on page 6-8: Applicant argues that the prior art relied upon in the preceding office action does not teach the following limitations of the presently amended claims: "wherein the ultrasonic waves are generated by an ultrasonic head positioned adjacent to an outer surface of tubing that acts as a channel for fluid to flow from the dialysis machine to the device, wherein the ultrasonic head and tubing are configured such that the ultrasonic waves travel through the fluid along the tubing to the circuitry." See examiner's rejection as necessitated by the amendment, below, which details the newly relied upon prior art which is relied upon for anticipating/teaching the aforementioned presently amended claimed subject matter. Regarding applicant’s argument regarding dependent claims on page 9: Applicant argues that their preceding arguments render the independent claims allowable, and consequently likewise the dependent claims are allowable. See examiner's rejection as necessitated by the amendment, below, detailing the prior art which discloses/teaches the limitations of the dependent claims. 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, 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim 1-4, 6-8, 11-14, and 16-18 are rejected under 35 U.S.C. 103 as being unpatentable over US 20100106028 A1, henceforth written as Penner, in view of US 20170141601 A1, henceforth written as Halliburton.
