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 .
Priority
Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d).
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 1-4, 6, 8, 11, 13-15 and 17-26 are rejected under 35 U.S.C. 101 because the claimed invention is directed to abstract idea without significantly more. The claims 1 and 17 recite: “dividing data, adding a first reference sequence, performing inverse Fourier transform, and performing inverse Fourier transform”. This is generic data manipulation (dividing data and adding sequence) and mathematical processing (inverse Fourier transform), which is an abstract idea. The claims merely adapt the mental process of generating data and subsequently perform mathematical process. This judicial exception is not integrated into a practical application because the applicant has failed to establish how to dividing the data and performing the IFFT contribute to improving the operation in a specific technology environment. The claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception because "processor, memory, and non-transitory storage medium" is a generic computer element and each step does no more than require a generic computer to perform generic computer functions. The generic computer functions do not add meaningful limitation to the abstract idea. Therefore, the limitations amount to no more than the abstract idea of generating data.
Claims 23 and 26 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claims do not fall within at least one of the four categories of patent eligible subject matter because recitation: “a computer-readable storage medium” can not be excluded from being a signal or carrier wave. Therefore, claims are illegible.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 2025/0088318 Pudeev et al disclose cyclic prefix (CP) and IFFT in OFDM system. US 2024/0089044 Ma et al disclose flexible frame structure and CP.
