Office Action

§101 §112
CTNF 18/400,225 CTNF 87611 DETAILED ACTION This action is responsive to the application filed 12/29/2023. Claims 1-17 are pending. 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. Claim 15 is rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim does not fall within at least one of the four categories of patent eligible subject matter because the claim recites a system comprising a plurality of modules, each of which carries out various steps of acquiring and evaluating data, making predictions, and carrying out calculations. Therefore, the broadest reasonable interpretation of Claim 15 includes an interpretation where each of the recited modules is a software module. As software is not considered a process machine, manufacture, or composition of matter within the scope of the statute, the broadest reasonable interpretation of the claim includes a non-statutory embodiment and therefore must be rejected. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claims 1-17 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which a joint inventor regards as the invention. Claim 1 recites the limitations of "the stress," “the state of charge,” “the correlation,” and “the state of health.” There is insufficient antecedent basis for these limitation in the claim. Claim 15 contains the same antecedent basis deficiencies, and they are likewise incorporated into the other claims which depend from or reference Claim 1. Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Birke, et al., U.S. PGPUB No. 2008/0231284 and Arnold, et al., U.S. PGPUB No. 2014/0107949 disclose systems for testing and determining the state of health of a battery, accounting for the stress the battery undergoes .
