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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 03/20/2026 has been entered.
Response to Amendment
Claims 1-13 are pending. Claim 1 is currently amended.
Claim Objections
In claim 1, consider use of --a dry cleaner floating lifter connected to the dry cleaner-- and --a wet cleaner four-link lifter-- and amending the dependent claims to recite --the dry cleaner floating lifter-- (four link lifter with respect to the wet cleaner is not recited in the dependent claims). This would help distinguish the “the floating lifter is a parallelogram four-link lifter configured to switch the dry cleaner between a lifting state and a lowering state under action of an external force” aspect in claim 2. Also consider amending claim 2 to recite -- the floating lifter is a parallelogram dry cleaner four-link lifter-- for further distinction between the two four link lifters recited.
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) 1-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Farmer (US 20180199785 A1) in view of Yun (KR 20170090688 A) and Oshida (JP H05245086 A).
With respect to claim 1, Farmer discloses An automatic cleaning apparatus comprising: a mobile platform configured to move automatically on an operating surface (mobile platform as robot body 105, fig. 1, [0068], robot automatically [autonomously] moves as in [0047]); and a cleaning module disposed on the mobile platform (cleaning module including a dry cleaner 200, fig. 2; [0051]), and comprising: a dry cleaner configured to clean at least a part of the operating surface by dry cleaning (a dry cleaner 200, fig. 2, [0051-0052], having floor extractors 265, 270, fig. 2 to clean surfaces as in [0052-0054], Farmer also provides for vacuum in [0060]); and a floating lifter connected to the dry cleaner and configured to enable the dry cleaner to passively move vertically relative to the mobile platform (the linkage arrangement suspending housing 215 from a frame 205, fig. 7, as in [0055] including suspension linkage 1600, fig. 14, [0094], allows the dry cleaning brush to move passively, in response to undulations during travel, over the floor as described in [0055])
Farmer does not explicitly disclose a wet cleaner configured to clean at least a part of the operating surface by wet cleaning, and a four-link lifter disposed between the wet cleaner and the mobile platform to enable the wet cleaner to automatically lift and lower relative to the mobile platform, the four-link lifter is a parallelogram structure, comprising: a first connecting end for providing active power to switch the wet cleaner between a lifting state and a lowering state; and a second connecting end disposed opposite to the first connecting end and rotating with rotation of the first connecting end.
Yun, in the same field of endeavor, as related to cleaning, teaches of providing a wet cleaner configured to clean at least a part of the operating surface by wet cleaning (wet cleaner as mop plate 30, figs. 2-3, [0024], and provides wet cleaning as it can wipe [mop] a wet floor- see description of prior art in fig. 1 and the water supply in [0005] of Yun; Yun provides this together with a dry cleaner/vacuum as described in [0019], with relation to the intake duct 12 and brush 14 shown in fig. 2; also providing a mop plate connector 30, fig. 4 with an elevator guide 45 with a lifting sleeve 45a and lifting rail 45b to allow the mop plate to be lifted; [0035]). Yun describes that this arrangement enables the cleaner to handle multiple types of floors ([0007,0009-0010]).
It would have been obvious for a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified Farmer, with the wet cleaner taught by Yun, for the purpose of handling multiple types of floors.
Regarding a four-link lifter disposed between the wet cleaner and the mobile platform to enable the wet cleaner to automatically lift and lower relative to the mobile platform, Yun, as noted above, provides a lifting arrangement (Yun, also providing a mop plate connector 30, fig. 4 with an elevator guide 45 with a lifting sleeve 45a and lifting rail 45b to allow the mop plate to be lifted; [0035]). Oshida, in the same filed of endeavor, related to cleaning, teaches of a four-link lifter (four link lifter including links 42 and 43, fig. 7, symmetrically disposed, [0033]) disposed between the wet cleaner (disposed between an analogous wet cleaner pad 62, fig. 7; [0042-0045]) and the mobile platform (1, fig. 7; [0015]) to enable the wet cleaner to automatically lift and lower relative to the mobile platform (the wet cleaner can automatically lift and lower because of a spring bias using spring 48, fig. 7; [0039], to follow the floor) , the four-link lifter is a parallelogram structure ([0033] describes parallelogram link), comprising: a first connecting end for providing active power to switch the wet cleaner between a lifting state and a lowering state (first connecting end proximate to 49, [0034], there is a stopper 5 with a claw piece 5a, fig. 8 at that end [0040], where active power can be applied to release the claw to allow the wet cleaner to switch from a lifting state to a lowering state by operating the stopper/claw; claim does not require a motor or any specific source of active power and can be met by enabling the active power to be provided manually); and a second connecting end disposed opposite to the first connecting end and rotating with rotation of the first connecting end (a second end at the linkage proximate to 75, fig. 7, because it is a rotating bar, it rotates together as described in [0038,0040-0042]). Oshida describes this arrangement as improving a cleaning effect, while also enabling smooth movement while not cleaning ([0006]).
It would have been obvious for a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified Farmer, with four bar parallelogram linkage of Oshida for improved cleaning, while also enabling smooth movement while not cleaning.
With respect to claim 2, Farmer, as modified, teaches the limitations of claim 1 above, and further teaches the floating lifter is a parallelogram four- link lifter configured to switch the dry cleaner between a lifting state and a lowering state under action of an external force (Farmer, 4 link structure with links 1305, 1405, as shown in fig. 14, [0092, 0094], there are 4 links 1610a-d, fig. 16, and [0092], provides that link 1305 can be link 1610a, in fig. 16; see [0108-0109]; the links allow for vertical translation in [0109]).
With respect to claim 3, Farmer, as modified, teaches the limitations of claim 2 above, and further teaches wherein, the floating lifter comprises: a first fixed bracket fixedly connected to the mobile platform (Farmer, first fixed bracket 205, fig. 8, fixed to robot cleaner as shown in fig. 2 [205 is shown as a underlined reference character in fig. 2]; [0051,0055]), a second fixed bracket fixedly connected to the dry cleaner (Farmer, second fixed bracket 215, fig. 8, [0072], with the dry cleaner as brushes/floor extractors 265, 270, mounted therein in [0075]) and a connecting rod pair (Farmer, connecting rod pairs 1610a-1610b, figs. 16-18; [0108-0109]), having one end rotatably connected to the first fixed bracket through movable studs (Farmer, first end connected to first bracket at 820a, 820b, though studs, as in figs. 8, 18, [0118], studs as pin joints in [0108]), and another end rotatably connected to the second fixed bracket through movable studs (connected to second fixed bracket at 825a, 825b, figs. 8, 17, through slotted pin joints [movable studs] as in [0108]).
With respect to claim 4, Farmer, as modified, teaches the limitations of claim 3 above, and further teaches wherein, the connecting rod pair comprises: a first connecting rod pair (Farmer, first rod pair 1601a, 1601b, fig. 16; [0108]), having one end rotatably connected to a first end of the first fixed bracket through movable studs (Farmer, previously explained in rejection of claim 3, above, and applies to all 4 linkages/rods, see [0108]), and a second end rotatably connected to a first end of the second fixed bracket through movable studs (Farmer, previously explained in rejection of claim 3, above, and applies to all 4 linkages/rods, see [0108]); and a second connecting rod pair disposed opposite to the first connecting rod pair (Farmer, second rod pair 1601c, 1601d, fig. 16; [0108]), and having one end rotatably connected to a second end of the first fixed bracket through movable studs (Farmer, previously explained in rejection of claim 3, above, and applies to all 4 linkages/rods, see [0108]), and a second end rotatably connected to a second end of the second fixed bracket -through movable studs (Farmer, previously explained in rejection of claim 3, above, and applies to all 4 linkages/rods, see [0108]).

Response to Arguments
Applicant's arguments filed 03/20/2026 have been fully considered but they are not persuasive.
With respect to the arguments directed towards Farmer, Yun and Wang (response pages 6-9), the applicant argued that Farmer does not disclose the claimed parallelogram 4 bar linkage for the wet mop. The examiner notes that Farmer is not relied upon for this aspect. As for Yun, the applicant notes that Yun uses a sliding sleeve and lifting rail to lift the mop. The examiner also notes that Yun is not relied upon for the parallelogram 4 bar linkage for the wet mop. As for Wang, the examiner notes that it is not relied upon in this rejection, and the arguments with respect to Wang are rendered moot.
The examiner respectfully submits that Oshida teaches the claimed 4 bar parallelogram linkage, as applied to a wet mop cleaner, and provides the beneficial effect of improving cleaning, while also allowing the mop to be lifted to not impede smooth movement while not in use.
