Office Action

§103
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 . Specification The disclosure is objected to because of the following informalities: Claims page 3, line 1, “20. 75 (Cancelled)” should read –20-75 (Cancelled)--; Claims page 3, line 15, “107.” is unclear; Appropriate correction is required. Claim Objections Claim 15 is objected to because of the following informalities: Claim 15, “aa base” should read – a base--. Appropriate correction is required. 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. Claim(s) 1, 11, 15-16, 17, 82 is/are rejected under 35 U.S.C. 103 as being unpatentable over US Patent 7,543,339 B1 to Harris in view of WO 2020/092224 Al to Shine Bathroom Tech, Inc. Re. claims 1 and 82, Harris discloses a modular bidet 59 comprising a cabinet assembly 65; a pumping unit 83 and a bidet mixing valve 94 comprising an outer shell, the pumping unit 83 engaging a cartridge 78, and the bidet mixing valve 94 configured to control an amount of liquid flow from the cartridge 78; and a tractable bidet sprayer 58 (see column 13, line 11- column 15, line 15 and figures 4-24). Harris fails to explicitly recite a mixing tank comprising a tank column assembly positioned within an outer shell, mixing core which engages the tank column assembly, and a lower tank assembly with a mixing needle; however, in an analogous prior art reference in the same field of endeavor, Shine teaches (see paragraphs [0052]-[0057] and figures 6,8D-1B) a pod 17, or mixing tank, installable and removable in a reservoir 19, when the pod 17 is pushed into a pod port 18, a foil is pierced by a pierce point 29, and other components 20 may be interfaced to a controller such as control valves. It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Harris as taught by Shine such that the motivation for having a tank column assembly positioned within an outer shell, where the mixing core engages the tank column assembly, and a lower tank assembly with a mixing needle would have been to provide solutions for controlling the liquid flow in order to balance the solution. HARRIS: PNG media_image1.png 616 448 media_image1.png Greyscale Re. claim 11, Harris modified by Shine further discloses a mixing core inner shell defines a mixing core chamber operable to receive a mixing pod 17 (see para 0008 and figures 11a/b). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Harris as taught by Shine such that the motivation for having a mixing core chamber would have been to provide solutions for controlling the liquid flow in order to balance the solution. Re. claim 15, Harris further discloses the base 64,65 further comprises a base housing having a length and a width, wherein the width decreases from a first end to a second end along the width (see figures 4-8). Re. claim 16, Harris further discloses the base 64,65 is configured to receive the retractable fluid applicator wand 58 within a recess on a front surface of the base. Re. claim 17, Harris further discloses the base 64,65 has a reel assembly 60 operable to wrap a fluid carrying tube engaging the retractable fluid applicator wand at a first end and the base at a second end around a pulley assembly (see figure 9). Claim(s) 2-3 and 76 is/are rejected under 35 U.S.C. 103 as being unpatentable over Harris and Shine as applied to claim 1 above and further in view of JP 06-003454U Obayashi CORP. Re. claims 2-3 and 76, Harris modified by Shine fails to explicitly disclose the retractable fluid applicator wand body with an elongated central housing aperture with a wand actuator at a first end of the elongated central housing aperture, and a pair of adjacent fluid delivery apertures; however, in an analogous prior art in the same field of endeavor, Obayashi teaches retractable fluid applicator wand 1 has a fluid applicator wand body with an elongated central housing aperture with a wand actuator 13 at a first end of the elongated central housing aperture, and a pair of adjacent fluid delivery apertures 11 shape selected from round, oval, ovoid, square, rectangular, and triangular (see claim 1, figures 2-3). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Harris in view of Shine as taught by Obayashi such that the wand body has adjacent fluid delivery outlets. The motivation for having a retractable fluid applicator wand body and fluid delivery apertures would have been to provide an adjustable bidet to a user in addition to multiple outlets for dispensing fluids. PNG media_image2.png 554 260 media_image2.png Greyscale Claim(s) 4-5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Harris and Shine as applied to claim 1 above in view of US 7,913,329 B2 Smith. Re. claims 4-5, Harris modified by Shine fails to explicitly disclose a piston valve having a lower piston housing chamber with an opening sized to receive an upper piston valve housing, and a piston valve ball positioned between a lower piston housing and an upper piston ball housing; however, in an analogous prior art in the same field of endeavor, Smith teaches a piston valve 18 further comprises a lower piston housing chamber 13a with an opening sized to receive an upper piston valve housing, and a piston (see column 6, lines 37-64 and figure 5) valve ball 31 positioned between a lower piston housing and an upper piston ball housing. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Harris in view of Shine as taught by Smith such that a lower piston housing chamber is adjusted to receive an upper piston valve housing. The motivation for housing the upper piston valve in the lower chamber would have been to prevent liquid flow therethrough. PNG media_image3.png 440 376 media_image3.png Greyscale Claim(s) 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Harris and Shine as applied to claim 1 above and further in view of EP 3486210 Al to Riprup Co. Re. claim 12, Harris modified by Shine fails to explicitly disclose a push- push mechanism; however, in an analogous prior art reference in the same field of endeavor, Riprup Co. teaches a push-push mechanism 12 (see para 0049 and figures 7-8). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Harris in view of Shine as taught by Smith because the substitution of one known lock mechanism for another would have yielded predictable results to one of ordinary skill in the art at the time of the invention. The motivation for a push-push mechanism would have been to securely open/close a device successively. PNG media_image4.png 562 354 media_image4.png Greyscale Claim(s) 13-14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Harris and Shine as applied to claim 1 above and further in view of US 7,690,392 B1 to Sarkiss. Re. claim 13, Harris modified by Shine fails to explicitly disclose an autofill hook that snaps into an autofill hook grappling notch; however, in an analogous prior art reference in the same field of endeavor, Sarkiss teaches an autofill hook 29a, 29 that snaps into an autofill hook grappling notch 2’ (see para 0036; figure 5 below). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Harris in view of Shine as taught by Sarkiss such that an autofill hook fits into notch. The motivation for using an autofill hook would have been to engage the lever securely. Re. claim 14, Harris further discloses a vent hole 109 (see figure 17) in cartridge 77. PNG media_image5.png 558 384 media_image5.png Greyscale Claim(s) 110 is/are rejected under 35 U.S.C. 103 as being unpatentable over WO 2020/092224 Al to SHINE. Re. claim 110, Shine discloses a pod 17-19, 30-31 comprising an encapsulation sheath 19 having a flattened spherical shape (see figure below) and additive solution (see page 11, para 0058-0059); however, Shine fails to explicitly recite a concentrated solution comprising lactic acid, mandelic acid, sodium diacetate, potassium sorbate, and polysorbate wherein the concentrated solution achieves a pH balance after a dilution of from 1:500 to 1:700 dilution in water and a pH between 3.8 and 5.5. It would have been obvious to one having ordinary skill in the art at the time the invention was made to a concentrated solution comprising lactic acid, mandelic acid, sodium diacetate, potassium sorbate, and polysorbate wherein the concentrated solution achieves a pH balance after a dilution of from 1:500 to 1:700 dilution in water and a pH between 3.8 and 5.5, since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. Absent a teaching as to criticality that the concentrated solution comprise lactic acid, mandelic acid, sodium diacetate, potassium sorbate, and polysorbate and the concentrated solution achieve a pH balance after a dilution of from 1:500 to 1:700 dilution in water and a pH between 3.8 and 5.5, this particular agreement is deemed to be known by those skilled in the art since the instant application and evidence of record fail to attribute any significance (novel or unexpected results) to a particular arrangement. The Applicant should note that where a change in size or range of a prior art reference merely represents a change of degree, and not a change of kind, such change is a design consideration within the skill of the art; further, where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. PNG media_image6.png 386 418 media_image6.png Greyscale Conclusion The prior art made of record (see USPTO Form 892) and not relied upon is considered pertinent to applicant’s disclosure. More specifically, US Patent 12,156,618 B2 Chen et al is directed to the state of the art as a teaching of a bidet and intelligent toilet. Claims 6-10 and 18-19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
