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. Claims 1-4 and 7-9 are rejected under 35 U.S.C. 103 as being unpatentable over Nakamura (JP 7-236696). In regards to claim 1, Nakamura teaches a three-way urology catheter stopcock (Figures 1-4B) comprising: a stopcock body (15) having a first end (20) and a second end (the bottom of the stopcock main body in which bottom lid 25 is fitted) and defining a longitudinally extending fluid flow passage extending from the second end in a direction of the first end (Figure 3B), the body having three connector mounting openings in a wall of the body (Figure 3B), wherein the second end defines an uninterrupted, planar surface (Figure 3B) an on/off selector (1) movably mounted within the fluid flow passage of the body (Figure 1), the on/off selector including a longitudinally extending, cylindrical selector body (2) having a first portion (7), a second portion (labeled in Figure 2B below), an open end (9), a closed end (Figure 2B), and three fluid flow openings (10) in a wall of the selector body (Figures 2A, 2B), the first portion having a first diameter, the entire second portion having a second diameter, the first diameter being greater than the second diameter, the second portion extending from the first portion to the three fluid flow openings (Figures 2A, 2B) wherein the closed end includes one of a plurality of fluid flow indicator members and fluid flow indicia (4/5/6) two first connectors (16/18) a second connector (17) PNG media_image1.png 288 456 media_image1.png Greyscale Nakamura does not teach the two first connectors “mounted in opposing connector mounting openings of the three connector mounting openings of the stopcock body” and the second connector “mounted in a connector mounting opening of the three connector mounting openings that is between the opposing connector mounting openings in which the two first connectors are mounted”, as Nakamura instead teaches the two first connectors integral to the stopcock body adjacent opposing connector mounting openings of the three connector mounting openings of the stopcock body (Figure 3B) and the second connector integral to the stopcock body adjacent a connector mounting opening of the three connector mounting openings that is between the opposing connector mounting openings the two first connectors are adjacent to (Figure 3A). But it would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the two first connectors and the second connector, of the stopcock of Nakamura, to be mounted in opposing connector mounting openings of the three connector mounting openings of the stopcock body and mounted in a connector mounting opening of the three connector mounting openings that is between the opposing connector mounting openings in which the two first connectors are mounted, respectively, as an obvious matter of design choice, as either the two first connectors and the second connector being integral to the stopcock body, or the two first connectors and the second connector being mounted in the connector mounting openings of the stopcock body, thus being separable components, will allow for the same end result of allowing fluid flow through the stopcock. And the two first connectors and the second connector being mounted in the connector mounting openings of the stopcock body, thus being separable components, additionally will allow for replacement of damaged components and continued use of undamaged components. In regards to claim 2, in the modified stopcock of Nakamura, Nakamura teaches wherein the stopcock body is cylindrical (Figure 3A). In regards to claim 3, in the modified stopcock of Nakamura, Nakamura teaches wherein the two first connectors define a catheter port and a drainage bag port (Figures 1, 3A, 3B). In regards to claim 4, in the modified stopcock of Nakamura, Nakamura teaches wherein the two first connectors are barbed fittings configured for push-on connection to a flexible tube (Figures 1, 3A, 3B).

In regards to claim 5, in the modified stopcock of Nakamura, Nakamura teaches wherein the second connector is a needle-free fitting (17) (Figure 3A); however, Nakamura is silent about whether the needle-free fitting is normally closed with a male Luer thread. Matsumoto et al teaches a three-way urology catheter stopcock (Figures 1-14B) wherein a second connector is a normally closed needle-free fitting (22/38) with a male Luer thread (74). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the needle-free fitting, of the modified stopcock of Nakamura, with a male Luer thread, as taught by Matsumoto et al, as such will allow for connection of a syringe with a luer lock connector to the needle-free fitting (paragraph [0071]) to make it possible for drug solution filled inside the syringe to be coinjected through the stopcock (paragraph [0072]) for treatment of the patient. However, Matsumoto et al is silent about why the needle-free connector is normally closed. Chen teaches a three-way urology catheter assembly (Figure 1) wherein a second connector is a normally closed needle-free fitting (6/7). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the needle-free fitting, of the modified stopcock of Nakamura and Matsumoto et al, to be normally closed, as taught by Chen, as such will allow for continuously puncturing infusing without leaking, and especially can be used in the clinical treatment to the patient who needs to perform repeated rinsing and injection (Abstract). In regards to claim 6, in the modified stopcock of Nakamura, Matsumoto et al, and Chen, Nakamura is silent about wherein the second connector is configured for connection to a corresponding female Luer fitting on a medication dispensing device. Matsumoto et al teaches wherein the second connector is configured for connection to a corresponding female Luer fitting (104/108) on a medication dispensing device (Figures 14A, 14B)(paragraph [0071]). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the second connector, of the modified stopcock of Nakamura, Matsumoto et al, and Chen, to be configured for connection to a corresponding female Luer fitting on a medication dispensing device, as taught by Matsumoto et al, as such will allow for connection of a syringe with a luer lock connector to the needle-free fitting (paragraph [0071]) to make it possible for drug solution filled inside the syringe to be coinjected through the stopcock (paragraph [0072]) for treatment of the patient. Claims 10-14 and 17-19 are rejected under 35 U.S.C. 103 as being unpatentable over Nakamura, and further in view of JP 59-140977.

Response to Arguments Applicant's arguments filed July 20, 2026, have been fully considered but they are not persuasive: In regards to claim 1, Applicant argued: Nakamura fails to teach or suggest a second end in which a longitudinally extending fluid flow passage extends, where the second end defines an uninterrupted, planar surface. Instead, Nakamura describes a top of a cylindrical part surface having recesses 21, 22, 23 formed therein. (See Nakamura, paragraph [0007]; Fig. 3A.) (Remarks, page 6). Examiner disagrees. Nakamura teaches a second end (the bottom of the stopcock main body in which bottom lid 25 is fitted) and defining a longitudinally extending fluid flow passage extending from the second end in a direction of the first end (20) (Figure 3B), wherein the second end defines an uninterrupted, planar surface (Figure 3B). In regards to claim 10, Applicant argued: As discussed above, Nakamura fails to teach or suggest a second end in which a longitudinally extending fluid flow passage extends, where the second end defines an uninterrupted, planar surface. Instead, Nakamura describes a top of a cylindrical part surface having recesses 21, 22, 23 formed therein. (See Nakamura, paragraph [0007]; Fig. 3A.) (Remarks, page 7). Examiner disagrees. Nakamura teaches a second end (the bottom of the stopcock main body in which bottom lid 25 is fitted) and defining a longitudinally extending fluid flow passage extending from the second end in a direction of the first end (20) (Figure 3B), wherein the second end defines an uninterrupted, planar surface (Figure 3B). In regards to claim 21, Applicant argued: As discussed above, Nakamura fails to teach or suggest a second end in which a longitudinally extending fluid flow passage extends, where the second end defines an uninterrupted, planar surface (Remarks, pages 8-9).
