Office Action

§101
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 . Applicant(s) Response to Official Action The response filed on February 9, 2026 has been entered and made of record. Response to Amendment Claims 1, 2, 5, 7-8, 12, and 13 have been amended. Claim 14 has been added. Claims 1-14 are pending in the application. Applicant’s arguments and/or amendments to the claim(s) has/have overcome each and every claim objection, and claim rejection under 35 U.S.C. 112 and 35 U.S.C. 102, previously set forth in the Office Action mailed November 7, 2025. Accordingly, the claim objection(s) and claim rejections under 35 U.S.C. 112 and 35 U.S.C. 102 articulated therein are withdrawn. 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 1-14 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (abstract idea) without significantly more. Each of independent claims 1, 12, 13, and 14 are directed to process(es) of mathematical calculation. Thus, the claims are directed to an abstract idea. This judicial exception is not integrated into a practical application. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the claimed “memory”, “processing units”, and “non-transitory computer-readable storage media” are generically-recited computer elements that do not add any meaningful limitation to the aforesaid abstract idea, because they amounts to simply implementing the abstract idea on a computer. Dependent claims 2-11 are each dependent from claim 1, do not appear to remedy the aforesaid deficiencies of claim 1 under this title, and are therefore also rejected under this title by virtue of that dependency. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: See PTO-892. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
