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.
Claims 1, and 3-15 are rejected under 35 U.S.C. 103 as being unpatentable over Raphael (DE102008029687A1) in view of Roth (US 3,820,189)
Regarding claim 1, Raphael discloses a cleaning robot (connects to a vacuum source of any kind, no robotic features recited, vacuums have a certain level of self control that makes them robotic to a degree), comprising: a negative pressure space (Items 2 provides suction to the housing (Item 5). Everything within the housing is subject to negative pressure); wherein,
the negative pressure space is enclosed by a base of the robot (Figure 16 item 5 or 30), a duster cloth (Item 4) and a surface to be cleaned exposed by the duster cloth, and the negative pressure space directly faces the surface to be cleaned exposed by the duster cloth and is directly in contact with the surface to be cleaned exposed by the duster cloth (Item 13); and
wherein, the duster cloth comprises a layer of wiping cloth (Items 21) in contact with the surface to be cleaned, a detachable connection part (Paragraph 10) close to and detachable from a base of the robot, and a sealing layer (Items 22 and 27) located between the wiping cloth and the detachable connection part, the sealing layer comprises a sealing film (Paragraph 104-118).
Raphael fails to explicitly disclose wherein the duster cloth is arranged on the base of the robot and is arranged along edges of the base of the robot, the negative pressure space is located on a middle portion of the base of the robot.
Roth teaches a cleaning tool wherein the duster cloth is arranged on the base and is arranged along edges of the base of the robot, the negative pressure space is located on a middle portion of the base (Item 14). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Raphael to move the apertures to the middle of the cleaning tool as taught by Roth. Roth further discusses how having the aperture in the middle of the cleaning tool is “very effective particle removal is achieved, the brush, to a greater degree than would be expected, moving the particles in the rug or the like, loosely in the brushing direction, and aiding in the withdrawal of the particles by the vacuum, while the vacuum tends to lift both the particles themselves, and the pile of the rug, to make the particles more easily extracted and the pile more easily brushed” (Column 1 Lines 6-20).
Regarding claim 3, Raphael in view of Roth disclose the cleaning robot according to claim 1, wherein the sealing layer is made of a sponge (Item 27) made by an integral skin foaming processing (limitation viewed as a product by process, since this is a product claim, the process of foaming is not necessary to the claim), and wherein the sponge made by the integral skin foaming processing has a skin with a first density and a core with a second density, and the first density is larger than the second density (Raphael; Figure 15, Paragraph 118).
Regarding claim 4, Raphael in view of Roth disclose the cleaning robot according to claim 1, wherein the sealing layer comprises a sponge and one layer of sealing film provided on at least one of the upper side and the lower side of the sponge (Raphael; Items 22 and 27).
Regarding claim 5, Raphael in view of Roth disclose the cleaning robot according to claim 1, wherein said detachable connection part is a hooked-loop connection member (Raphael; Paragraph 10, Velcro is a form of hook and loop fastener).
Regarding claims 6 and 7, Raphael in view of Roth disclose the cleaning robot according to claim 3 (or 4). Raphael fails to explicitly disclose wherein the thickness of the sponge is larger than 2 mm and less than 3 mm.
The thickness of the sponge is determined based on the type of material and the density of the foaming material, there are different elastic values of the foamed layer. Thus optimizing the thickness based on elastic properties of the foamed layer, the floor type in which it is intended to be used, and the weight of the cleaning machine, would result in a result effective variable. A result effective variable is a variable in which achieves a recognized result as set forth above. Therefore since the general conditions of the claim (e.g. having the claimed structure as recited above) is disclosed by Raphael it is not inventive to discover the optimum workable range by routine experimentation, and it would have been obvious to one of ordinary skill in the art at the time when the invention was filed to provide the thickness of the of the foam layer to be larger than 2mm and less than 3mm. Further in the instant application Paragraphs [25] applicant has not disclosed any criticality (or unexpected result) for the claimed limitations. Such a modification is viewed as a change in size, which has been held to be of routine skill in the art (see MPEP 2144.04).
Regarding claim 8, Raphael in view of Roth disclose the cleaning robot according to claim 1, further comprising: a walking unit (Raphael; Item 9), and a vacuumizing unit; wherein, the vacuumizing unit comprises a fan motor and fan blades (Paragraph 137).
Regarding claim 9, Raphael in view of Roth disclose the cleaning robot according to claim 1, wherein the sealing layer is elastic (Raphael; Item 27 is foam).
Regarding claim 10, Raphael in view of Roth disclose the cleaning robot according to claim 1, wherein the duster cloth is an independent integrated element related to the base of the robot (Raphael; Paragraph 113).
Regarding claim 11, Raphael discloses a cleaning robot, comprising: a negative pressure space (Items 2 or 8); wherein,
the negative pressure space is enclosed by a base of the robot (Figure 16 Item 5 and 30), a duster cloth (Item 4) and a surface to be cleaned exposed by the duster cloth, and the negative pressure space faces directly the surface to be cleaned exposed by the duster cloth and is directly in contact with the surface to be cleaned, exposed by the duster cloth;
and wherein, the duster cloth comprises a layer of wiping cloth in contact with the surface to be cleaned (Item 21), a detachable connection part close to and detachable from a base of the robot (Paragraph 10), and a sealing layer (Items 22 and 27) located between the wiping cloth and the detachable connection part, and the sealing layer is elastic (foam is elastic).
Raphael fails to explicitly disclose wherein the duster cloth is arranged on the base of the robot and is arranged along edges of the base of the robot, the negative pressure space is located on a middle portion of the base of the robot.
Roth teaches a cleaning tool wherein the duster cloth is arranged on the base and is arranged along edges of the base of the robot, the negative pressure space is located on a middle portion of the base (Item 14). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Raphael to move the apertures to the middle of the cleaning tool as taught by Roth. Roth further discusses how having the aperture in the middle of the cleaning tool is “very effective particle removal is achieved, the brush, to a greater degree than would be expected, moving the particles in the rug or the like, loosely in the brushing direction, and aiding in the withdrawal of the particles by the vacuum, while the vacuum tends to lift both the particles themselves, and the pile of the rug, to make the particles more easily extracted and the pile more easily brushed” (Column 1 Lines 6-20).
Regarding claim 12, Raphael in view of Roth disclose the cleaning robot according to claim 11, wherein the duster cloth is an independent integrated element related to the base of the robot (Raphael; Paragraph 113).
Regarding claim 13, Raphael in view of Roth disclose the cleaning robot according to claim 11, wherein the cleaning robot is adsorbed onto a surface through the negative pressure space (the vacuum and weight of the cleaning device draws the device closer to the floor).
Regarding claim 14, Raphael in view of Roth disclose the cleaning robot according to claim 11, wherein the sealing layer comprises a sealing film, and the sealing film is provided on at least one of an upper side and a lower side of the wiping cloth (Raphael; Item 22; Paragraph 104-118).
Regarding claim 15, Raphael in view of Roth disclose the cleaning robot according to claim 1, wherein the duster cloth surrounds a sealing chamber (Raphael; Item 11; Roth Figure 4).
Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Raphael (DE102008029687A1) in view of Roth (US 3,820,189) in view of You (US 2005/0144752).
Regarding claim 2, Raphael in view of Roth disclose the cleaning robot according to claim 1. Raphael fails to explicitly disclose wherein the sealing layer is made of a foamed EPDM material (Raphael does disclose a foam layer 27, but no discussion of the specific material of EPDM).
You teaches a floor cleaning device wherein the foamed layer is made of an EPDM material (Paragraph 29). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to simply substitute the material of the foam layer of Raphael for the EPDM material as taught by You. Such a modification is viewed as a change in material, which has been held to be of routine by one of ordinary skill in the art (see MPEP 2144.04). When looking at the instant application there is no criticality given to the material of EPDM. EPDM is a commonly used rubber material for seals due to its anti-mold properties.
Response to Arguments
Applicant’s arguments, filed 9/29/2025, with respect to the rejection(s) of claim(s) 1 and 11 under 102-Raphael have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Raphael in view of Roth , as discussed above, discloses the negative pressure space being in the middle of the base of the cleaning tool.
