Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-2, 4-9, and 11-12 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Leland (US 3336603). Regarding claim 1, Leland discloses a WC-deodorizing device comprising: a fastening device (40-41) for a spray container (20) on an outside (see Fig. 1-2) of a WC bowl (12), a tube system (25-29) which can be connected to an actuating element (36) of a spray container (20) and leads into the bowl interior (interior of 12) via the rim (32) of the WC bowl (see Fig. 2), wherein the WC-deodorizing device comprises an ergonomically shaped grip element (22 is rounded and therefore ergonomically shaped), wherein the grip element comprises a central receiving opening (34) for an actuating element (36) and two contact surfaces (two surfaces near the opening 34) for fingers, which contact surfaces are arranged to the sides of the receiving opening (see Fig. 5), the grip element comprises a connector (21, 37) for connection to the spray container (see Fig. 5), the tube system comprises a flexible tube (col. 2, ll. 40-43) which leads into the interior (interior of 12) of the WC bowl between the WC seat (15-16) and the upper bowl rim (34) of the WC bowl (see Fig. 2), the flexible tube is, at a first end (end near 36) thereof, connected to the actuating element (see Fig. 5) at the height of a dispensing opening of the spray container (see Fig. 2 and 5) and, at a second end thereof, comprises an outlet opening (outlet opening of 28 near 31), the WC-deodorizing device furthermore comprises a positioning element (31, 50) that is fastened to a second end (end of 28 connecting to 31) of the tube and is positioned in the bowl interior of the WC bowl (see Fig. 2), the positioning element contains a counterweight (50; col. 2, ll. 43-47), preferably on the bottom side thereof, and the tube ends, with the second end thereof, in the positioning element (see Fig. 2 and 5) and the outlet opening is preferably arranged in the region of the positioning element. Regarding claim 2, Leland discloses the tube system is composed of a flexible tube (col. 2, ll. 40-43). Regarding claim 4, Leland discloses the grip element is embodied in mirror symmetry relative to the center axis (22 is mirror-symmetrical, see Fig. 2-5). Regarding claim 5, Leland discloses the grip element comprises an opening (29) on the side facing the WC bowl (see Fig. 2 and 5) and the flexible tube is guided through the opening (see Fig. 2 and 5). Regarding claim 6, Leland discloses the positioning element is a plastic part or a metal part (col. 2, ll. 43-47) which is formed to be funnel-shaped (see Fig. 2 and 5), teardrop-like, round (see Fig. 2 and 5), or oval and is slid over the tube (see Fig. 2 and 5; col. 2, ll. 43-47). Regarding claim 7, Leland discloses the counterweight is a metal body (col. 2, ll. 43-47) that is preferably completely surrounded by the positioning element. Regarding claim 8, Leland discloses the positioning element is asymmetrical (31 is shown to be asymmetrical in Fig. 2 and 5) and/or the counterweight is decentrally arranged in the positioning element. Regarding claim 9, Leland discloses the connector comprises a screw lock, a buckle lock, a magnet lock, or a clip lock (col. 2, ll. 2-7). Regarding claim 11, Leland discloses the WC-deodorizing device comprises a spray container (20) with an actuating element (36) and the actuating element is preferably a spray head. Regarding claim 12, Leland discloses the spray container is a compressed gas container (col. 1, l. 72 - col. 2, l. 7) or a pump spray container. 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. Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Leland (US 3336603) in view of Huitron (US 20200181898). Regarding claim 3, Leland discloses substantially all of the elements of the present invention as stated above in the rejection of claim 1. Leland further discloses the tube preferably has an inner diameter between 0.5 mm and 10 mm, preferably 0.5 mm and 2 mm; however, Leland does not disclose the flexible tube is a silicone tube or a plastic tube as claimed. Huitron discloses an automatic toilet bowl cleaning apparatus and methods wherein disclose the flexible tube is a silicone tube or a plastic tube (¶ 0029). It would have been obvious to one of ordinary skill in the art to have modified the flexible tube of Leland, to be plastic as claimed, as taught by Huitron, since it was known in the art that vinyl plastic is a suitable material to construct flexible tubes (¶ 0029). Claim(s) 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Leland (US 3336603) in view of Sternitzky (US 20220145606). Regarding claim 10, Leland discloses substantially all of the elements of the present invention as stated above in the rejection of claim 1. Leland further discloses the fastening device is in several parts, at least two parts (40-41); however, Leland does not disclose two magnets, wherein a first magnet is fastened on or in the grip element and a second magnet, which interacts with said first magnet, is fastened to the outside of the WC bowl as claimed. Sternitzky discloses a force actuated liquid dispenser including two magnets (¶ 0027), wherein a first magnet (¶ 0027) is fastened on or in the grip element (116, 118, 104) and a second magnet (¶ 0027), which interacts with said first magnet (¶ 0027), is fastened to the outside of the WC bowl (400). It would have been obvious to one of ordinary skill in the art to have modified the fastening device of Leland, to include magnets as claimed, as taught by Sternitzky, since it was known in the art that magnets are a form of mounts that can be used to secure a member to a toilet (¶ 0027). Conclusion The prior art made of record in the PTO-892 form and not relied upon is considered pertinent to applicant's disclosure. Page (US 9376794) is directed to the state of the art as disclosing a toilet bowl deodorizer fixture including a nozzle (16), a nut (22), a tube (15), a diaphragm (3), and a fluid reservoir (9).
