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 .
Claim Objections
Claim 1 is objected to because of the following informalities:
"clean solution" in line 5 appears to be a typo and should read "cleaning solution"
“so as to help the plurality of bristles remove stains from the to-be-cleaned surface” in lines 14-15 is intended use and carries no patentable weight
Appropriate correction is required.
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.
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.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Welbourne (US 10806320 B1).
Regarding claim 1, Welbourne discloses a rotating brush (item 100, figure 1) comprising:
a rotating brush body (items 101, 111, 112, and 153, figures 2 and 1);
a cavity configured to store a clean solution (item 151, figure 1);
and a controlling device (item 104, figure 2);
wherein the cavity and the controlling device are arranged in the rotating brush body (figures 1 and 2);
a motor is provided in the rotating brush body (item 144, figure 1), and an output shaft of the motor (item 131, figure 3) is provided with a brush disk (item 123, figure 1);
a lower surface of the brush disk is uniformly provided with a plurality of bristles (item 122, figure 1);
the motor is configured to drive the brush disk to rotate, so as to drive the plurality of bristles on the brush disk to clean a to-be-cleaned surface (col. 5, lines 3-23);
the controlling device is configured to control the cleaning solution in the cavity to be sprayed toward the to-be-cleaned surface, so as to help the plurality of bristles remove stains from the to-be-cleaned surface (col. 2, lines 62-64; col. 3 lines 48-56).
Allowable Subject Matter
Claims 2-8 are 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:
Claim 2 and 6 are allowed primarily because the prior art of record cannot anticipate
Applicant’s claimed invention by a single reference nor render Applicant’s claimed invention obvious by the combination of more than one reference.
The prior art of record, Welbourne (US 10806320 B1) and those cited on PTO-892, do not teach a rotating brush “wherein the cavity comprises a cavity body, a dispensing device, and a first nozzle” or “a water-stopping ball is provided in the second through hole” and “a first water-stopping ball is provided at an end of the water inlet channel away from the negative-pressure chamber” as within the context of the claimed invention as disclosed and within the context of the other limitations present in claims 2 and 6.
Therefore, the prior art of record cannot anticipate Applicant’s claimed invention by a single reference nor render Applicant’s claimed invention obvious by the combination of more than one reference.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The prior art cited on PTO-892 disclose subject matter related to various types of rotating brushes and cleaning devices.
