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 .
This communication is in response to request filed on 06/19/2026.
In the application claims 1, 3, 5-11, 13, and 15-20 are pending. Claims 2, 4, 12, and 14 have been canceled.
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.
Claims 1, 3, 5-11, 13, and 15-20 are 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.
Claims 1 and 11 recite, “calculating a volume of fluid in the pumping chamber when the chamber is not full or empty…” There seems to be improper antecedent basis for the claimed “the chamber” in line 18. Applicant is requested to maintain the antecedent basis.
Claims 3, 5-10, 13, and 15-20 are rejected by the virtue of their dependency.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
McGill, David W. et al. (US 2019/0099534 A1) “a disposable fluid handling cassette, such as that useable with an APD cycler device or other infusion apparatus, includes a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for fluid that includes a channel.” See ¶ 0021, “a method for determining a volume of fluid moved by a pump includes measuring a first pressure for a pump control chamber when the pump control chamber is isolated from a reference chamber. The pump control chamber may have a volume that varies at least in part based on movement of a portion of the pump, such as a pump membrane or diaphragm. A second pressure may be measured for the reference chamber when the reference chamber is isolated from the pump control chamber.” See ¶ 0066, and “determine a volume of fluid moved by the pump,” See ¶ 0069, 0074, 0079, 0081.
