CTNF 18/964,892 CTNF 81335 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). Information Disclosure Statement The information disclosure statement submitted on 12/02/2024 has been considered and made of record by the examiner. Specification 06-31 AIA The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. Claim Objections 07-29-01 AIA Claim s 2-7 are objected to because of the following informalities: as to claims 2-7, acronym “MAP” is not spelled out in the claims . Appropriate correction is required. 07-29-01 AIA Claim s 10-14 are objected to because of the following informalities: as to claims 10-14, acronym “MAP” is not spelled out in the claims . Appropriate correction is required. 07-29-01 AIA Claim 20 is objected to because of the following informalities: as to claim 20, acronym “MAP” is not spelled out in the claim . Appropriate correction is required. Claim Rejections - 35 USC § 101 07-04-01 AIA 07-04 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 1-20 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea (mathematical concepts) without significantly more. Claim 1 recites the steps of “A log-likelihood ratio (LLR) generation method in a multiple input multiple output (MIMO) system, the LLR generation method comprising: converting a symmetric transmission symbol into an asymmetric transmission symbol corresponding to a modulation order, the symmetric transmission symbol being included in a reception signal vector; and generating an LLR based on the reception signal vector, a channel matrix, and the asymmetric transmission symbol by using an LLR generation algorithm.” The step of “A log-likelihood ratio (LLR) generation method in a multiple input multiple output (MIMO) system, the LLR generation method comprising: converting a symmetric transmission symbol into an asymmetric transmission symbol corresponding to a modulation order, the symmetric transmission symbol being included in a reception signal vector” is a mathematical concept executed using mathematical formulas (see claim 9). The step of “generating an LLR based on the reception signal vector, a channel matrix, and the asymmetric transmission symbol by using an LLR generation algorithm” is also a mathematical concept that is implemented using a mathematical algorithm. According to the Court, concepts determined to be abstract ideas and, thus, patent ineligible, include certain methods of organizing human activity, such as fundamental economic practices (Alice, 573 U.S. at 219-20; Bilski, 561 U.S. at 611); mathematical formulas (Parker v. Flook, 437 U.S. 584, 594-95 (1978)), and mental processes (Gottschalk v. Benson, 409 U.S. 63,67 (1972)). Nothing in the claim, understood in light of the specification, requires anything other than off-the-shelf, conventional computer, network, and display technology for gathering, sending, and presenting the desired information; see also Alice. Therefore, the claim as a whole is directed to an abstract idea. This judicial exception is not integrated into a practical application because no additional elements are cited in the claim. Therefore, the claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. Claims 2-9 are rejected for the same reason. Claim 10 recites the steps of “A log-likelihood ratio (LLR) generation method in a multiple input multiple output (MIMO) system, the LLR generation method comprising: generating a first common variable based on a reception signal vector and a channel matrix; obtaining asymmetric transmission symbols based on the reception signal vector, the asymmetric transmission symbols having asymmetry corresponding to a modulation order; selecting N transmission symbols from among the asymmetric transmission symbols, "N" being a natural number; calculating a Euclidean distance based on the first common variable and the N transmission symbols; and generating an LLR based on the Euclidean distance by using a max-log MAP algorithm.” The steps cited in claim 10 are all mathematical concepts executed using mathematical formulas and mathematical algorithms. According to the Court, concepts determined to be abstract ideas and, thus, patent ineligible, include certain methods of organizing human activity, such as fundamental economic practices (Alice, 573 U.S. at 219-20; Bilski, 561 U.S. at 611); mathematical formulas (Parker v. Flook, 437 U.S. 584, 594-95 (1978)), and mental processes (Gottschalk v. Benson, 409 U.S. 63,67 (1972)). Nothing in the claim, understood in light of the specification, requires anything other than off-the-shelf, conventional computer, network, and display technology for gathering, sending, and presenting the desired information; see also Alice. Therefore, the claim as a whole is directed to an abstract idea. This judicial exception is not integrated into a practical application because no additional elements are cited in the claim. Therefore, the claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. Claims 11-14 are rejected for the same reason. Claim 15 recites the steps of “A multiple input multiple output (MIMO) detection circuit provided in a receiving device of a MIMO system, the MIMO detection circuit comprising: processing circuitry configured to generate a first common variable based on a reception signal vector and a channel matrix, convert a symmetric transmission symbol into an asymmetric transmission symbol corresponding to a modulation order, the symmetric transmission symbol being included in the reception signal vector, calculate a Euclidean distance based on the first common variable and the asymmetric transmission symbol, and generate a log-likelihood ratio (LLR) based on the Euclidean distance.” The steps cited in claim 15 are all mathematical concepts executed using mathematical formulas and mathematical algorithms. According to the Court, concepts determined to be abstract ideas and, thus, patent ineligible, include certain methods of organizing human activity, such as fundamental economic practices (Alice, 573 U.S. at 219-20; Bilski, 561 U.S. at 611); mathematical formulas (Parker v. Flook, 437 U.S. 584, 594-95 (1978)), and mental processes (Gottschalk v. Benson, 409 U.S. 63,67 (1972)). Nothing in the claim, understood in light of the specification, requires anything other than off-the-shelf, conventional computer, network, and display technology for gathering, sending, and presenting the desired information; see also Alice. Therefore, the claim as a whole is directed to an abstract idea. This judicial exception is not integrated into a practical application because no additional elements are cited in the claim. Therefore, the claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. Claims 16-20 are rejected for the same reason. No patentable weight has been given to the limitations cited in the preambles of the claims.
