Office Action

§102
DETAILED ACTION 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 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. (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(s) 1 and 2 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Noh et al (US 2019/0320867). Noh et al teach a system comprising: A vacuum cleaner (100); A battery (138); A circuit for controlling the vacuum cleaner (control unit 140); A sensor for detecting movement (sensor unit 170); A cradle for charging the battery (charging base 200). The vacuum is disclosed as movable and operational with the use of the battery. See at least Figures 2, 5, 6 and the related description and the description at [0060-77], [0093-103], [0171-179], [0382-394]. Noh et al also teach a method. The method comprises: vacuuming by the vacuum (100) in response to movement detected by the sensor (170) (at least [0388-389]); and charging the battery (138) of the vacuum via the cradle (200) (at least [0071-73], [0112]). The vacuum is disclosed as removable from the cradle and operational by the battery. See at least Figures 2, 5, 6 and the related description and the description at [0060-77], [0093-103], [0171-179], [0382-394]. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The documents listed on the attached PTO 892 are cited to show the state of the art with respect to the vacuum cleaners with batteries, sensors and charging bases and the methods of their operations.
