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 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)(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 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by CN 111895571 A. In regards to claim 1, CN 111895571 A teaches a test device for an a filter (abstract states that a sensor detects a blockage of the filter) comprised in an air channel of a portable air purifier (FIG. 1 shows the filter placed in an overall channel of the device), the test device comprising a sensor inlet and a sensor outlet, the sensor inlet being connectable to the air channel of the portable air purifier, the test device further comprising a filter condition sensor, positioned between the sensor inlet and the sensor outlet, and configured to analyze a condition of the air filter (please see highlighted text in the provided PDF document, as well as FIG. 1). Allowable Subject Matter Claims 2-22 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.
