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 submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement The information disclosure statements (IDSs) submitted on 08/30/2024 and 10/27/2025 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements have been 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 1-20 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. Claim 1 recites the limitation "the adjacent first conductor parts are connected by two second conductor parts arranged at intervals, and two adjacent first conductor parts are symmetrically arranged" in lines 6-8. There is a lack of antecedent basis for this limitation in the claim. Regarding claims 1 and 2, the limitation recites “… arranged at intervals” is unclear and leaves the reader in doubt as to the meaning of the technical feature to which it refers. It is unclear that what intervals are arranged? Claim 2 recites the limitation "wherein the first conductor part ..." in line 1, and the limitation recites “the first end of the first opening is connected to the second end of the second opening” in lines 5-6 . There is a lack of antecedent basis for this limitation in the claim. Claim 5 recites the limitation "the circumference of the first branch" in line 1. There is a lack of antecedent basis for this limitation in the claim. Regarding claims 5 and 8, the limitation recites “a high-frequency oscillator unit” is unclear and leaves the reader in doubt as to the meaning of the technical feature to which it refers. It is unclear that where does a high-frequency oscillator unit coming from? And it is unclear that what kind of technical relationship between “a high-frequency oscillator unit” has with “a low-frequency oscillator unit.” Maybe the antenna includes high-frequency oscillator units arranged in an array, which are placed directly below the low-frequency oscillator units. Regarding claims 3, 6 and 9, the limitation recites “two conductor parts” is unclear and leaves the reader in doubt as to the meaning of the technical feature to which it refers. It is unclear whether this recitation refers to "two first conductor parts," “two second conductor parts” or other "conductor parts.” Please review the claims carefully and check for antecedence basis. Claims 2-20 are depending on claim 1, and are rejected the same reasons under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph. Allowable Subject Matter Claims 1-20 are allowable if the 112 issues above are fixed.
