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)(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. 1. Claim 1 is rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Riedel (USPN 2019/0161204). Regarding claim 1, Riedel discloses a drone protection system (see figure 6) that protects a drone (a drone 10) from lightning strike (see par. 0021, 0130), the drone protection system comprising: a Faraday cage (a faraday cage 42, see par. 0139) enclosing the drone; and a wire (a cable 13) capable of moving along the Faraday cage (see par. 0012) while maintaining connection with the Faraday cage (42) with an end portion (one end of the cable 13) connecting to the Faraday cage (42)(see figure 6). Allowable Subject Matter 2. Claims 2-3 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. Conclusion 3. Any inquiry concerning this communication or earlier communications from the examiner should be directed to DANNY NGUYEN whose telephone number is (571)272-2054. The examiner can normally be reached M-F 8:00AM-4:30PM. Examiner interviews are available via telephone, in-person, and video conferencing using a USPTO supplied web-based collaboration tool.
