Office Action

§102 §103
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 . Response to Amendment This action is in response to the amendment and restriction filed on 8/17/2026. Claims 1-27 and 33-43 have been canceled and claims 28-32 and new added claims 44-61 are pending in the application. Election/Restrictions Applicant’s election without traverse of Group I in the reply filed on 8/17/2026 is acknowledged. Newly submitted claims 44-61 directed to an invention that is independent or distinct from the invention originally claimed for the following reasons: Generic claims 28, 50 and 56. Species I, claims 28-32, 50-54, 56, 61 discloses propagation model selection/parameterization, CBRS/MSO. Species II, claims 28, 44-47, 50, 56 discloses FWA restrict to network, associating criterion with FWA to create first level in order to generate a second level based on configuration of FWA and ranking them based on distance Species III, claims 28, 48, 50, 56 discloses feature map data. Species IV, claims 28, 49, 50, and 56 discloses data structure of addresses of each of wireless access nodes. Species V, claims 28, 50, 55, 56 discloses detecting interference of FWA. Species VI, claims 28, 50, 55, 56 discloses determining interference. Species VII, claims 28, 50, 56, 57 discloses select wireless access node based on response. Species VIII, claims 28, 50, 56, 58 discloses un-allocating spectrum. Species VIIII, claims 28, 50, 56, 59 discloses API cloud-based model. Species X, claims 28, 50, 56, 60 discloses adjusting antenna based on signal strength. Since, the branches includes claims 44-49, 55, 57-60 from independent claims 28, 50 and 56 create a serious burden for examiner to generate a different class, different search etc.. Since applicant has received an action on the merits for the originally presented invention, this invention has been constructively elected by original presentation for prosecution on the merits. Accordingly, claims 44-49, 55, 57-60 withdrawn from consideration as being directed to a non-elected invention. See 37 CFR 1.142(b) and MPEP § 821.03. The species II-X will be joined with species I when Species I is allowed. To preserve a right to petition, the reply to this action must distinctly and specifically point out supposed errors in the restriction requirement. Otherwise, the election shall be treated as a final election without traverse. Traversal must be timely. Failure to timely traverse the requirement will result in the loss of right to petition under 37 CFR 1.144. If claims are subsequently added, applicant must indicate which of the subsequently added claims are readable upon the elected invention. Should applicant traverse on the ground that the inventions are not patentably distinct, applicant should submit evidence or identify such evidence now of record showing the inventions to be obvious variants or clearly admit on the record that this is the case. In either instance, if the examiner finds one of the inventions unpatentable over the prior art, the evidence or admission may be used in a rejection under 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a) of the other invention. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
