In regards to Claim 36: A modified Herrera teaches of the device as claimed in claim 1, wherein the valve is operable to move from the second side of the fluid inlet in the closed position (Lundberg, Figure 2; “valve sleeve blocking flow”) to the first side of the fluid inlet in the open position (Lundberg, Figure 2; “injection operated configuration”). 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) 1-5, 11, 19, & 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over US 2018/0153671 hereinafter Herrera in view of US 2017/0314374 hereinafter Lundberg. In regards to Claim 1: Herrera teaches of a device for controlling urinary flow, comprising: a fluid inlet (Herrera, Paragraph 40; Figure 5 Item 505); a fluid outlet (Herrera, Paragraph 40); a valve movable between an open position in which fluid can flow from the fluid inlet to the fluid outlet and a closed position in which fluid flow is blocked between the fluid inlet and the fluid outlet (Herrera, Paragraph 40; Figure 5 Item 530); a valve seat located between the fluid inlet and the fluid outlet and arranged such that the valve engages with the valve seat in the closed position (Herrera, Paragraph 40; “In some embodiments, a valve 530 can be placed in the proximal portion 505 of the catheter”); wherein when the valve is in the open position, a flow path is formed between the fluid inlet and the fluid outlet (Herrera, Paragraph 38; “the urine in the bladder 550 can be voided when the user utilizes an external actuator 545 to open the valve 530 and allows the urine to travel through the urethra 560. This signal can be controlled by the user through the use of an external computing device 535.”); and an actuator operable to move the valve between the open position and the closed position (Herrera, Paragraph 40; “valve 530 can comprise an internal actuator”); wherein the actuator is positioned on a first side of the fluid inlet (Herrera Paragraph 40; valve 530 which contains an actuator is arranged upstream of the inlet); and wherein the fluid outlet is positioned on a second, opposite side of the fluid inlet (Herrera, Paragraph 40; Outlet is downstream from the inlet). However, Herrera does not teach wherein the valve seat is located close to the fluid inlet such that the valve is operable to move substantially out of a flow path when the valve is in the open position. Lundberg teaches wherein the valve seat is located close to the fluid inlet such that the valve is operable to move substantially out of a flow path when the valve is in the open position (Lundberg, Figure 2). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to add the valve moving substantially out of the flow path taught in Lundberg to the urinary control device of Herrera, the motivation being to provide an unobstructed flow path for urinary evacuation. In regards to Claim 2: A modified Herrera teaches of the device as claimed in claim 1, comprising an outlet tube extending between the fluid inlet and the fluid outlet (Herrera, Figure 6B Item 645; Paragraph 004).

Claim(s) 6 & 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over US 2018/0153671 hereinafter Herrera in view of US 2017/0314374 hereinafter Lundberg in view of US 2003/0225311 hereinafter Sayet. In regards to Claim 6: One embodiment of Herrera teaches all of claim 1, but does not teach a seal arranged between the fluid inlet and the actuator to prevent fluid flowing from the fluid inlet to the actuator. Sayet teaches a seal arranged between the fluid inlet and the actuator to prevent fluid flowing from the fluid inlet to the actuator (Sayet, Paragraph 0082; Figure 12 Item 1200) It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to add the sealed actuator compartment taught by Sayet to the urinary control device of Herrera , the motivation being to provide a water tight space to protect the electronic components in the actuator to prevent any electronic malfunction. In regards to Claim 7: A modified Herrera teaches wherein the actuator is located in a sealed compartment, wherein the sealed compartment is at least partially formed by the seal (Sayet, Paragraph 0082; Figure 12 Item 1204) Claim(s) 15, 17, 18, 22 & 34 is/are rejected under 35 U.S.C. 103 as being unpatentable over US 2018/0153671 hereinafter Herrera in view of US 2017/0314374 hereinafter Lundberg in view of US 2016/0135942 hereinafter Drager. In regards to Claim 15: A modified Herrera teaches all of claims 1 and 11, but does not teach wherein the first positioning structure comprises a skirt. Drager teaches wherein the first positioning structure comprises a skirt (Drager, Figure 1A Item 20). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to add the bladder skirt taught in Drager to the bladder control device of Herrera, the motivation being to ensure that there is no leakage from the bladder due to the device. In regards to Claim 17: A modified Herrera teaches all of claims 1 and 11, but does not teach wherein the first positioning structure is attached to the device at a position between the fluid inlet and the fluid outlet and adjacent to the fluid inlet. Drager teaches wherein the first positioning structure is attached to the device at a position between the fluid inlet and the fluid outlet and adjacent to the fluid inlet (Drager, Figure 1A Item 20 & 84). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to add the bladder skirt placed adjacent to the inlet taught by Drager to the bladder control device of Herrera, the motivation being to ensure that there is no leakage from the bladder due to the device. In regards to Claim 18: A modified Herrera teaches of claims 1 and 11, but does not teach wherein the first positioning structure is arranged when in the deployed configuration to position the fluid inlet adjacent to a urethral opening in the bladder. Drager teaches wherein the first positioning structure is arranged when in the deployed configuration to position the fluid inlet adjacent to a urethral opening in the bladder (Drager, Figure 1A Item 20 & 21). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to add the retention structure in the position described to the bladder control device of Herrera, the motivation being to provide a structure to funnel urine out of the bladder effectively without any leakage of the bladder. In regards to Claim 22: A modified Herrera teaches all of claim 1, but does not teach wherein the actuator comprises a solenoid arranged to impart a linear force on the valve to move it between the open position and the closed position. Drager teaches wherein the actuator comprises a solenoid arranged to impart a linear force on the valve to move it between the open position and the closed position (Drager, Paragraph 0150) (Drager, Figure 6C. Item 68). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to add the Solenoid structure taught by Drager to the valve actuator of Herrera, the motivation being to provide a method to remotely actuate the valve to allow the flow of urine. Claim(s) 26-28 is/are rejected under 35 U.S.C. 103 as being unpatentable over US 2018/0153671 hereinafter Herrera in view of US 2017/0314374 hereinafter Lundberg in view of US 6,638,208 hereinafter Natarajan.
