Office Action

§112
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 § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 20 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Claim 20 is depended on a method claim 1. However, the examiner will consider the claim 20 is depended on claim 11. If this interpretation is incorrect, Applicants should so advise. Allowable Subject Matter Claims 1-20 are allowed. The following is an examiner’s statement of reasons for allowance: Park et al. (US 2023/0361623), Petzel et al. (US 10819394), Song (US 2020/0127501), McFarthing (US 9281706) teach a method for charging wirelessly. However, none of prior art teaches a method for wireless charging by a wireless charging system comprising halting a listener from responding to a plurality of requests for communication with a poller, wherein the poller and the listener of the system form a wireless charging pair; counting a number of bits in the received response which is in error compared an expected bit sequence of a response to a transmitted request, wherein the count is greater than one; determining whether a near field communication (NFC) card is in proximity to the wireless charger based on the count of the number of bits; and performing the wireless charging of the system based on the determination, and a wireless charging system having the same as set forth in the claims. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to SEUNG H LEE whose telephone number is (571)272-2401.
