Office Action

§112
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 01/28/2026 has been entered. Response to Arguments Applicant's arguments filed 01/28/2026 have been fully considered as follows. The Arguments amendments presented overcome the prior presented rejections. Upon further review a new issue under 35 USC §112b was found and is presented below. 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 5 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim five states that the “first section of the second conductor is arranged in parallel to the first conductor”. In claim 1 from which claim 5 depends it is stated that a “a part of the second conductor” is arranged in parallel to the first conductor. As such it is ambiguous as to whether the first section is a subset of the “part of the second conductor” or is a new section that must be parallel to the first conductor. Allowable Subject Matter Claims 1-4, 6-9 and 11-13 are allowed. The prior art presented in the Non-Final Rejection of 03/19/2025 is still considered the closest prior art. However, the prior art does not teach or make obvious the combination of “wherein the first conductor and a part of the second conductor are arranged in parallel” and “a distance between the first conductor and the part of the second conductor between the power supply end of the magnetron and the power supply end of the frequency converter is less than a distance between the power supply end of the frequency converter and the ground end of the frequency converter.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to WOODY A LEE JR whose telephone number is (571)272-1051.
