Office Action

§101 §102 §112
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 . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. DETAILED ACTION Claims status Claims 1-11 are pending as the applicant filed on 08/01/2023. Claim Rejections - 35 USC § 112 2. 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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-11 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claims 1-11, the terms “degradation” “temperature of the secondary battery is low” are vague and a relative term that renders the claim indefinite. The terms “degradation” “temperature of the secondary battery is low” are not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably appraised of the scope of the invention. An artisan doing measuring and testing would not know at what point “degradation” “temperature of the secondary battery is low” within the scope of the claim had been accomplished because nothing within the disclosure establishes when a sufficient “degradation” “temperature of the secondary battery is low” occur. Note: In view of the PTO compact prosecution, the Examiner notes that due to the indefiniteness issues described above all consideration of the merits of the claims in view of prior art is as best understood. 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 1-11 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., a law of nature, a natural phenomenon, or an abstract idea) without significantly more. Claim 1, Step 1 the claim is a process (or machine) (Yes), Step 2A Prong One, does the claim recite an abstract idea? current claim related to a battery diagnostic system comprising: a load history acquisition unit configured to acquire a battery load history which is a history of a load applied to a secondary battery; an interpolation processing unit configured to, when a portion of constituent data of the battery load history is missing, estimate and interpolate the portion of constituent data using the rest of the constituent data, to estimate, based on the battery load history, a present degradation state of the secondary battery and a cause of degradation that has brought about the degradation state; a degradation prediction unit configured to predict a predicted degradation state of the secondary battery that will occur in a future upon having been used in a future use mode of the secondary battery for diagnosis, using a predicted battery load indicating a load predicted to be applied to the secondary battery according to the future use mode of the secondary battery and the present degradation state and the cause of degradation of the secondary battery estimated appears is an abstract idea of mental process (MPEP 2106.04(a)) or data gathering equivalent to mathematical concept or mathematical manipulation function (MPEP 2106.04 (a) (2) (concept need not be expressed in mathematical symbols, because "[w]ords used in a claim operating on data to solve a problem can serve the same purpose as a formula), (OR Mathematical Concepts and Mental Processes) Step 2A Prong One: Yes. Step 2A Prong Two, is the claim directed to an abstract idea? In other words, does claim recite additional elements that integrate the Judicial Exception into a practical application? the additional elements of a degradation estimation unit configured the degradation estimation unit are recited at a high level of generality and merely amount to a particular field of use (see MPEP 2106.05(h)) and/or insignificant post-solution activity (MPEP 2106.05(g)), this does not integrate the Judicial Exception into a practical application, Step 2A Prong Two: NO. Step 2B, Does the claim recite additional element that amount to significantly more than the Judicial exception? the additional element of an output unit configured to output the predicted degradation state of the secondary battery predicted by the degradation prediction unit appears to be field of use (See MPEP 2106.05(h) and MPEP 2106.05(f)) and/or merely amounts to insignificant extra-solution output of the results (see MPEP 2106.05(g)) and therefore fails to integrate the abstract idea into a practical application or amount to significantly more. Step 2B: No. claim 1 not eligible. Claim 2 related to a predicted load generation unit configured to, when the secondary battery is used according to the future use mode of the secondary battery, identify a load predicted to be applied to the secondary battery and generate the predicted battery load appears recite further data characterization and mathematical concepts that are part of the abstract idea, claims 2 not eligible.
