DETAILED ACTION 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. Response to Amendment The Amendment filed 2/19/26 has been entered. Claim 17 has been canceled. Claim 16 has been amended. Claims 1-16, and 18-20 remain pending in the application. Election/Restrictions Applicant's election with traverse of Group I in the reply filed on 2/19/26 is acknowledged and the arguments are found persuasive. The restriction requirement as set forth in the Office action mailed on 8/19/25 is hereby withdrawn.

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. 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).

Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 19 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 19, the phrase "such as" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d).

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. Claims 7 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Ekanem (U.S. 2020/0208615), as applied to claims 1 and 16 above, in view of Meager (U.S. 2015/0052885). Re claim 7: Ekanem discloses the system (Fig. 12) of claim 1 (as described above), wherein the first and second volume displacers (9, 11, 13, 15) comprise Ekanem fails to disclose reciprocating pumping kind of mechanisms. Meager teaches reciprocating pumping kind of mechanisms (5, pump - Para 143)(Para 143 - “…pump 5 may correspond to…reciprocating pump…”). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modeled the pumping kind of mechanisms of Ekanem after that of Meager, thereby making the pumping kind of mechanism of Ekanem reciprocating pumping kind of mechanism in the way taught by Meager, for the advantage of being able to force a flow of fluid from a main fluid line toward an outlet fluid line (Meager; Para 143). Re claim 19: Ekanem discloses the system (Fig. 12) of claim 16 (as described above), wherein the first volume displacer (9, 11, 13, 15) comprises a Ekanem fails to disclose a reciprocating pumping mechanism. Meager teaches a reciprocating pumping mechanisms (5, pump - Para 143)(Para 143 - “…pump 5 may correspond to…reciprocating pump…”). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modeled the pumping mechanism of Ekanem after that of Meager, thereby making the pumping mechanism of Ekanem a reciprocating pumping mechanism in the way taught by Meager, for the advantage of being able to force a flow of fluid from a main fluid line toward an outlet fluid line (Meager; Para 143). Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Ekanem (U.S. 2020/0208615) in view of Vamvas (U.S. 2021/0285415). Re claim 9: Ekanem discloses the system (Fig. 12) of claim 1 (as described above), wherein the first and second pistons (Modified Fig. 12 above - E, L) comprise Ekanem fails to disclose spring-loaded landing pads. Vamvas teaches spring-loaded landing pads (772, 774 - stops - Para 109)(see Fig. 16b and Para 109 - “…These stops can be cushions or springs…”). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modeled the landing pads of Ekanem after those of Vamvas, thereby making the landing pads of Ekanem spring-loaded landing pads in the way taught by Vamvas, for the advantage of being able to absorb impact of stopping mass (Vamvas; Para 109).
