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 .
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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 18JUN2026 has been entered.
Response to Arguments
Applicant’s arguments, see page 8, filed 28NOV2025, with respect to the rejection(s) of claim(s) 1 under 35 U.S.C. § 103 have been fully considered and are moot in view of new grounds of rejection prompted by Applicant’s amendment to claims. While the amended requirement of urine contacting a working end of the pressure transducer, this limitation is considered to be fulfilled through use of commonly known float switches which are used to indicate a liquid level. A new ground(s) of rejection is made in view of US 20100286559 A1 (Paz et al.) in view of US 7132041 B2 (Deng et al.), US 3809478 A (Talbot), US 20210311018 A1 (Harrington et al.), and US 20210170086 A1 (Kloffel et al.).
Claim Rejections - 35 USC § 103
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 (i.e., changing from AIA to pre-AIA ) 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.
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.
Claim(s) 1-3, 5, 7, 8, 10, 11, 15, 16, 21-26, 28, 29, 32, and 41 are rejected under 35 U.S.C. 103 as being unpatentable over US 20100286559 A1 (Paz et al.) in view of US 7132041 B2 (Deng et al.), US 3809478 A (Talbot), US 20210311018 A1 (Harrington et al.), and US 20210170086 A1 (Kloffel et al.).
Regarding claim 1, Paz teaches a system for performing urinalysis of a transurethral patient (Fig. 1A), comprising:
a tubing set (108) configured to receive urine from a urine drainage catheter (102) [0115], the tubing set including a chamber (1208) in fluid communication with a lumen of the tubing set (Fig. 12A) [0251];
a detector assembly (at least 110, 112, 114 and 116) operatively coupled with the tubing set (Fig. 1A), wherein the detector assembly comprises:
a light source (emitter) [0257, 0258] configured to project a coherent light beam through the urine sample within the chamber (1208), and
a light receiver (sensor) [0257, 0258] configured to:
collect light exiting the urine sample, and
provide electrical signals to the module in accordance with characteristics of the collected light, the electrodes [0259] necessarily outputting an electrical signal; and
a urinalysis module (150) coupled with the detector assembly, wherein the system is configured to perform urinalysis of a urine sample contained within the chamber [0115, 0251];
the electrical signals which include color signals defined by refracted light exiting the sample [0256], the output considered to correspond to a color composition of the urine sample [0128] (color detection and output of color sensors as described in [0256] being considered to provide an output corresponding to the measured color).
Paz further teaches the detector assembly (at least 110, 112, 114 and 116) comprises a urine sensor configured to provide an electrical signal (the electrodes being considered to provide an electrical signal) to the module (150) and measuring parameters such as flow [0216] or detecting a stoppage in flow [0221], but fails to teach indicating when the chamber is full of urine, vertical flow of urine within the chamber, or disposal of a pressure transducer at the top of the chamber.
