Office Action

§102
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 . Election/Restrictions Applicant’s election without traverse of claims 1, 6, 8, 9 and 11 in the reply filed on 10/28/2025 is acknowledged. Information Disclosure Statement The information disclosure statement (IDS) submitted on 04/08/2025, 12/14/2023 and 08/30/2023 have been considered by the examiner and been placed of record in the file. Allowable Subject Matter Claims 6 and 8 are allowed. Claims 6 and 8 are allowed based on the prior art of record Li et al. (T-Shaped Decoupling Network for Wideband Isolation Improvement Between Two Strongly Coupled Antennas), Osamu (JP 2014127977 A), De Luis et al. (US 20140159986 A1) and Nishimoto et al. (JP 2013172172 A) it is agreed that the prior art of record does not teach the claimed invention as a whole including the following cited limitation: “wherein the first transmission line is formed by connecting a third transmission line and a fourth transmission line in series, the second transmission line is formed by connecting a fifth transmission line and a sixth transmission line in series, the third susceptance circuit is a series resonance circuit, and the decoupling circuit comprises: a first matching circuit disposed between the third transmission line and the fourth transmission line; and a second matching circuit disposed between the fifth transmission line and the sixth transmission line” Claims 9 and 11 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Li et al. (T-Shaped Decoupling Network for Wideband Isolation Improvement Between Two Strongly Coupled Antennas). Claim 1. Li et al. disclose A decoupling circuit comprising (FIG. 1): a first antenna element (FIG.1 Antenna 1); a second antenna element (FIG.1 Antenna 2); a ground conductor (read as substrate with ground size of Lx W = 45mmx22mm (Section III). FIG.1, ground connection); a first transmission line whose first end is connected to the first antenna element (FIG.1, Transmission line connected to antenna 1); a second transmission line whose first end is connected to the second antenna element (FIG.1, Transmission line connected to antenna 1); a first susceptance circuit whose first end is connected to a second end of the first transmission line (FIG.1, capacitor C1 connected to Transmission line that is connected to antenna 1); a second susceptance circuit whose first end is connected to a second end of the second transmission line and whose second end is connected to a second end of the first susceptance circuit (FIG.1, capacitor C1 connected to Transmission line that is connected to antenna 2); a third susceptance circuit (FIG.1 capacitor C2 and inductor L2) whose first end is connected to the second end of the first susceptance circuit and whose second end is connected to the ground conductor (FIG.1 capacitor C2 and inductor L2 connected to ground); a first input and output terminal connected to the first end of the first susceptance circuit (FIG.1, Port 1); and a second input and output terminal connected to the first end of the second susceptance circuit (FIG.1, Port 2), wherein the first susceptance circuit is a first parallel resonance circuit (FIG.1, The parallel connection of C1 and R1 and connected to transmission that connected to antenna 1. It is not clear if the term “parallel resonance” is composed of two susceptance connected in parallel.), the second susceptance circuit is a second parallel resonance circuit (FIG.1, The parallel connection of C1 and R1 and connected to transmission that connected to antenna 2. It is not clear if the term “parallel resonance” is composed of two susceptance connected in parallel.). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Refer to PTO-892.
