Office Action

§102 §103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Information Disclosure Statement Examiner note: copies of the foreign documents on the information disclosure statement filed 09/05/24 are available in the parent application files. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer.

Claim Rejections - 35 USC § 102 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. 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. (a) the invention was known or used by others in this country, or patented or described in a printed publication in this or a foreign country, before the invention thereof by the applicant for a patent. Claim(s) 1-3 and 10 – 12 is/are rejected under pre-AIA 35 U.S.C. 102(b) as being anticipated by US Patent 6,279,173 (hereinafter Denzin). Regarding claims 1 and 10, Denzin discloses a touchless actuation system for a toilet/a toilet comprising: a toilet reservoir (152), at least one sensor (112) located within a toilet reservoir (152) and configured to generate at least one signal indicative of a distance to an object within a detection region (col. 9, ln. 53-59); a motor assembly (col. 7, ln. 34-40); and a processing circuit (58) configured to receive the at least one signal from the at least one sensor to detect the object within the detection region based on the at least one signal and cause an actuation of the motor assembly in response to the detected object (col. 8, ln. 33-44), the detection region being external to the toilet (col. 8, ln. 24-32). Regarding claims 2 and 11, Denzin discloses the toilet actuation system of claim 1, wherein the at least one sensor includes: a first sensor located configured to generate a first signal indicative of a first distance to the object within the detection region; and a second sensor configured to generate a second signal indicative of a second distance to the object within the detection region (col. 9, ln. 66-col. 10, ln. 14). Regarding claims 3 and 12, Denzin discloses the toilet actuation system of claim 2, wherein the processing circuit is configured to determine whether the object is closer to the first sensor or the second sensor based on the first distance and the second distance (col. 10, ln. 8-12). 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 pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made. Claim 1-7, 10-16, and 19 is/are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over US Patent Application Publication 2011/0197350 (hereinafter Dudley) in view of Denzin. Regarding claims 1 and 10, Dudley discloses a touchless actuation system for a toilet/a toilet comprising: a toilet reservoir (3); at least one sensor (23a) Regarding claims 2 and 11, Dudley fails to show the at least one sensor includes: a first sensor located configured to generate a first signal indicative of a first distance to the object within the detection region; and a second sensor configured to generate a second signal indicative of a second distance to the object within the detection region. Attention is again turned to Denzin which teaches a first and second sensor for generating first and second signals indicative of distances to the object within the detection region (col. 9, ln. 66-col. 10, ln. 14). It would have been obvious to one having ordinary skill in the art to modify the sensor of Dudley such as that taught by Denzin above to allow for more precise sensing as evidenced by the teachings of Denzin mentioned above. Regarding claims 3 and 12, under the modification in view of Denzin, Denzin shows wherein the processing circuit is configured to determine whether the object is closer to the first sensor or the second sensor based on the first distance and the second distance (col. 10, ln. 8-12). Regarding claims 4 and 13, Dudley shows the first signal corresponds to a long flush (par. 35). Regarding claims 5 and 14, Dudley shows wherein the first signal corresponds to a short flush (par. 35). Regarding claims 6 and 15, Dudley shows wherein at least one signal indicates a first gesture for a long flush (par. 35). Regarding claims 7 and 16, Dudley shows wherein at least one signal indicates a second gesture for a short flush (par. 35). Regarding claim 19, Dudley shows a method comprising: receiving a signal from at least one sensor (23a) indicative of a gesture within a detection region (par. 35), 35); and initiating a flush action for the flush duration (par. 35). Dudley fails to show the at least one sensor is located within a toilet reservoir. Attention is turned to Denzin which teaches a control system for a toilet with a sensor (112) located within a toilet tank reservoir that actuates a motor assembly based on a detection signal from the sensor, teaching that such a configuration allows for a more accurate sensor and detection region as compared to a conventional infrared sensor (col. 1, ln. 59-col. 2, ln. 5; col. 2, ln. 31-40). It would have been obvious to one having ordinary skill in the art to modify the system of Dudley to locate the sensor within the closed reservoir to provide a more accurate sensing configuration as evidenced by the teachings of Denzin mentioned above. Claims 8-9, 17-18, and 20 rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Dudley and Denzin as applied to claim 1-7, 10-16, and 19 above, and further in view of US Patent 7,565,706 (hereinafter Janssen). Regarding claims 8-9, 17-18, and 20, Dudley is silent as to the style of the toilet tank and thus fails to show it is an in-wall tank, and furthermore that it is made of vitreous that is opaque. Attention is turned to Janssen which shows mounting a toilet tank in-wall (20) is a suitable location depending on a user’s design needs, and to select opaque vitreous china is a well-known material based on its suitability for its intended use (col. 6, ln. 36-40). Accordingly, it would have been obvious to one having ordinary skill in the art to configuration the toilet tank of Dudley as an in-wall tank, and to select vitreous opaque china as a matter of design considerations known in the art and suitable for their intended use as evidenced by the teachings above. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US Patent 8,281,422 is directed to the state of the art of hidden sensors for flush valves in plumbing fixtures.
