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. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 10 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over Hackert et al. (U. S. Patent Publication No. 2020/0329933 A1) in view of Jeong (KR20220006981 A). Regarding Claim 10, Hackert teaches the cleaner station of claim 1, as discussed above. Hackert does not explicitly teach: a cover opening unit disposed in the housing and configured to open a discharge cover of the dust bin of the first cleaner, wherein the control unit operates the flow path switching module before the cover opening unit operates. Jeong, however, teaches a cover opening unit (cover opening unit, 150; Fig. 13) disposed in the housing (100) and configured to open a discharge cover of the dust bin of the first cleaner (Paragraph [0284]), wherein the control unit (control unit, 400) operates the flow path switching module (switching valve, 183) before the cover opening unit (150) operates (Paragraph [0460]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the cleaner station of Hackert to further include a cover opening unit disposed in the housing and configured to open a discharge cover of the dust bin of the first cleaner, wherein the control unit operates the flow path switching module before the cover opening unit operates, as taught by Jeong, to provide a station a smooth, controlled opening and closing action, allowing technicians to easily reach internal components for inspection, cleaning, or repair, thus allowing for reduced time and effort needed for maintenance tasks. Regarding Claim 11, Hackert teaches the cleaner station of claim 1, as discussed above. Hackert does not explicitly teach a door unit disposed in the housing and configured to open or close the first cleaner flow path, wherein the control unit operates the flow path switching module before the door unit operates. Jeong, however, teaches a door unit (door unit, 140) disposed in the housing (100; Paragraph [0262]) and configured to open or close the first cleaner flow path (Paragraph [0262]), wherein the control unit (400) operates the flow path switching module (182) before the door unit (140) operates (Paragraph [0426]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the cleaner station of Hackert to further include a door unit disposed in the housing and configured to open or close the first cleaner flow path, wherein the control unit operates the flow path switching module before the door unit operates, as taught by Jeong, to provide a station a smooth, controlled opening and closing action, allowing technicians to easily reach internal components for inspection, cleaning, or repair, thus allowing for reduced time and effort needed for maintenance tasks. Allowable Subject Matter Claim 3 is 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. The following is a statement of reasons for the indication of allowable subject matter: Although Hackert et al. (U. S. Patent Publication No. 2020/0329933 A1) in view of Jeong (KR20220006981 A) teach the cleaner station, the references alone or in combination fail to teach, suggest or make obvious the flow path switching module comprises: a casing disposed in the housing and having a first cleaner flow path connection portion connected to the first cleaner flow path, and a second cleaner flow path connection portion connected to the second cleaner flow path; a connection hose disposed in the casing and having an inlet selectively coupled to any one of the first cleaner flow path connection portion and the second cleaner flow path connection portion; and a position sensor disposed in the casing and configured to detect a position of the connection hose and transmit a signal to the control unit, and wherein the control unit stops an operation of the flow path switching module when the control unit receives the signal from the position sensor, as required by claim 3. Claim 4 is further objected as being dependent on objected claim 3. Conclusion Art made of record, however, not relied upon for the current rejection is as follows: U. S. Patent Publication No. 2023/0346183 A1 to Choi teaches docking station, which includes a cover opening and closing device for automatically opening and closing a dust container cover, and a cleaning device is provided. The cleaning device includes a cleaner which includes a dust container for collecting foreign substances, a dust container cover rotatably coupled to the dust container so as to open and close the dust container, and a button provided to open the dust container, a docking station to which the cleaner is coupled, and which charges the cleaner coupled thereto, and a cover opening and closing device which opens the dust container cover by pressing the button and closes the dust container cover by pressing the dust container cover.
