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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statements (IDS) submitted on 12/13/24 and 2/4/25 were filed. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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. Claims 8 and 17 are 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. With regards to claim 8 and 17, applicant recites “ the second filter is the other of: the low-pass filter, and the high-pass filter”. Examiner is unclear what applicant intends by this limitation. Allowable Subject Matter Claims 1-7 and 9-16 and 18 are allowed. The following is a statement of reasons for the indication of allowable subject matter: With regards to the claims 1-7 and 9-16, the prior art does not disclose or fairly teach the specific circuit configuration with emphasis on at least a first filter having a first output reflection coefficient and configured, based on the first input reflection coefficient of the load, to modify at least a magnitude of the first output reflection coefficient of the first filter, and at least a first phase shifter connected to the first filter and configured to introduce at least a first phase shift to the first output reflection coefficient of the first filter; wherein the tuning component is configured to simultaneously match, at each of the first and second frequencies, the source impedance to the load impedance; and wherein the tuning component is tunable so as to enable adjustment of one or more of: the first output reflection coefficient, and the first phase shift. With regards to claim 18, the prior art does not disclose or fairly teach the specific circuit configuration with emphasis on dual-band tuning component having an input connected to the source and an output connected to the load, and comprising: a band pass filter having an output reflection coefficient and configured, at the first frequency and the second frequency, but not at frequencies below the first frequency and at frequencies above the second frequency, to modify, based on the input reflection coefficient of the load, a least a magnitude of the output reflection coefficient of the band pass filter, and a dual-band phase shifter connected to the filter and configured to introduce, at the first frequency, a first phase shift to the output reflection coefficient of the band pass filter and, at the second frequency, a second phase shift to the output reflection coefficient of the band pass filter; wherein the tuning component is configured to simultaneously match, at each of the first and second frequencies, the source impedance to the load impedance. Any inquiry concerning this communication or earlier communications from the examiner should be directed to KIMBERLY E GLENN whose telephone number is (571)272-1761. The examiner can normally be reached M-F 8:00 AM-5:00 PM. Examiner interviews are available via telephone, in-person, and video conferencing using a USPTO supplied web-based collaboration tool.
