Office Action

§101 §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 . 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. Claim Objections Claim 21 is objected to because of the following informalities: (a) Claim 21 depends on claim 20, however claim 20 has been cancelled, accordingly the claim dependency needs correction. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1, 2, and 32 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., an abstract idea) without significantly more. The claim(s) recite(s) “determining a first tracking area code (TAC) obtaining mode supported by a network-side device; determining a second TAC obtaining mode supported by a terminal; and based on the first TAC obtaining mode and the second TAC obtaining mode, determining a mode of obtaining a target TAC”. The limitations of determining the TAC obtaining modes supported by a network-side device and a terminal, and determining a mode for obtaining a target TAC, as drafted, are processes that under its broadest reasonable interpretation, covers concepts that can be performed by a human mind (including an observation, evaluation, judgement, opinion). This judicial exception is not integrated into a practical application because the claims fail to recite additional elements to apply or use the judicial exception that imposes a meaningful limit on the judicial exception. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the claims only recites that the method “is applied to a terminal” which is a simple recitation of a generic computer element. Therefore, the claims are not patent eligible. 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. Claims 1-5, 7, 11, 13, 14, 16-18, 21, 28, 32, and 34 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by GAO et al. (WO 2020/034324, cited on IDS filed on 04/28/2023).
