Office Action

§101
CTNF 19/118,201 CTNF 83066 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. Information Disclosure Statement The references listed in the Information Disclosure Statement(s) filed on 4/3/2025 have been considered by the examiner (see attached PTO-1449 form or PTO/SB/08A and 08B forms). 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 1-7 are rejected under 35 U.S.C. 101 because the claimed invention is directed to abstract ideas without significantly more. The claim(s) recite(s): A synchronization detection system comprising: a pseudo-vorticity matrix calculation unit that calculates a matrix having elements each of which is a discretized value of a phase difference obtained by two of the oscillators by time evolution (mathematical concept/calculation); a partial synchronization set detection unit that detects a plurality of subsets of the oscillators that have no common portion and are partially synchronized in a set of a finite number of the oscillators in the synchronization graph generated by the synchronization graph generation unit (mental process of evaluating graphically displayed information); and a synchronization index calculation unit that generates an index characterizing partial synchronization of the oscillator system using a calculation result calculated by the pseudo-vorticity matrix calculation unit and a partial synchronization set detected by the partial synchronization set detection unit (mathematical concept/calculation). This judicial exception is not integrated into a practical application because the functions of the system are essentially all mathematical calculations based on gathered data and mental process evaluations of the data. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the only limitations directed to non-abstract ideas are: a phase information output unit that outputs time evolution information of phases from an oscillator system including a finite number of oscillators (obtaining and providing data); and a synchronization graph generation unit that generates a synchronization graph that visualizes two-point synchronization with a graph representation (displaying data graphically). Obtaining/providing/outputting data and displaying information were not found to be considered as an improvement to an existing technology, and are therefore not considered as providing significantly more than the abstract ideas. See MPEP 2106.05. Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Liu et al. (US 2019/0090193) discloses performing partial synchronization (para. 0092). Kilian et al. (US 2021/0385768) discloses detecting partial synchronization packets and information regarding a number of clock cycles of an oscillator.
