Office Action

§112
DETAILED ACTION Acknowledgement is made of the preliminary amendment submitted on 06/24/2025. In virtue of this amendments: Claims 7-10 are newly added; Claims 3-6 are currently amended; and thus, Claims 1-10 are pending; 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 Acknowledgment is made of this application’s status as a 371 of PCT/JP2022/048520 filed on 12/28/2022. Information Disclosure Statement The information disclosure statement (IDS) submitted on 06/24/2025 has been considered by the examiner. Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. 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 1-10 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. Regarding claim 1, the claim recites “the anode pieces” on line 5, which renders the claim indefinite, as there is a lack of antecedent basis for said term, as previous recitation of the term is “a plurality of anode pieces” recited on line 3, thus should read “the plurality of anode pieces”. Regarding claim 1, the claim recites “the cavity resonator outside” on like 8 which renders the claim indefinite, as it is unclear the meaning of the term. Regarding claim 1, the claim recites “the outside surface” on lines 12 and 13, which renders the claim indefinite as there is a lack of antecedent basis for said term. Regarding claim 1, the claim recites “the shield casing” on line 16, which renders the claim indefinite, as there is a lack of antecedent basis for said term, as previous recitation of the term is “a sealable shield casing” recited on line 11, thus should read “the sealable shield casing”. Regarding claim 6, the claim recites “the shield casing” on line 1 and line 3, which renders the claim indefinite, as there is a lack of antecedent basis for said term, as previous recitation of the term is “a sealable shield casing” recited on line 11 in claim 1, thus should read “the sealable shield casing”. Regarding claim 6, the claim recites “the interior of the waveguide” on lines 3, which renders the claim indefinite as there is a lack of antecedent basis for said term. Regarding claim 10, the claim recites “the shield casing” on line 1 and line 3, which renders the claim indefinite, as there is a lack of antecedent basis for said term, as previous recitation of the term is “a sealable shield casing” recited on line 11 in claim 1, thus should read “the sealable shield casing”. Regarding claim 10, the claim recites “the interior of the waveguide” on lines 3, which renders the claim indefinite as there is a lack of antecedent basis for said term. Regarding claims 2-10, the claim are rejected based upon dependency of rejected claim 1, as all dependent claim inherits the deficiencies of the based claim. Allowable Subject Matter Claim 1 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claims 2-10 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. Regarding claim 1, none of the prior art of record alone or in combination thereof discloses or renders obvious all of the claimed limitation recited in the claims, for example: the anode cylindrical structure has a communication hole comprising a first opening that opens to an area surrounded by the shield casing and a second opening that opens to an interior of the waveguide Regarding claims 2-10, the claims are allowed based upon dependency of allowed independent claim 1 and may not be allowable when presented independently without all the claimed limitation of the base claim.
