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 . 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 8-10 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 limitations “a cluster configuration unit”, “an overlapping range calculation unit”, “an adjustment unit” in claims 8, 9, and 10 invoke 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. Therefore, the claim is indefinite and is rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. Reasons for Allowance The following is an examiner’s statement of reasons for allowance for claims 1-7: CHUNG ANG University (Foreign Doc. No. 10-2018-0014271 from IDS dated 3/4/2024) teaches, (a) grouping, based on local information of pre-shared secondary terminals, each secondary terminal into each local cluster (Fig. 6, page 13, 4th paragraph, a total of four clusters, clusters 0 to 3, can be configured based on the four directions of the cooperative spectrum sensing device (FC) in the cognitive wireless network included in cluster 3); (b) generating overlapping of the respective secondary terminals in each local cluster (page 14, 4th paragraph from the bottom, The generator 320 generates control information to control the operation of the plurality of auxiliary transmitters based on the connection matrix and sensing information indicating overlap between the sensing areas in each sensing direction of the plurality of auxiliary transmitters); and (c) calculating and adjusting between the respective local clusters (page 14, 2nd paragraph from the bottom It may include sensing direction limitation information that limits. The transmission unit 330 transmits the generated control information to the plurality of auxiliary transmitters). However, CHUNG ANG University does not teach claim limitations “determining a beam determination binary indicator of the each secondary terminal by using the overlapping point information… adjusting the overlapping range between the respective local clusters”. KIM et al. (10-1603036 from IDS) discloses Fig. 1 a multi-cluster based industrial wireless cognitive sensor network, and, in the middle of page 7, improves performance in terms of average dela time and transmission speed in large-scale sensor nodes. neither CHUNG ANG University nor KIM teaches “determining a beam determination binary indicator of the each secondary terminal by using the overlapping point information… adjusting the overlapping range between the respective local clusters”. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. PIAO et al. (CN 110402610) discloses Fig. 14.
