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 Preliminary Amendment Preliminary Amendment filed on 02/06/2023 noted by the examiner, claims 1-12 are pending. 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 1-12 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 claim 1-9 the terms “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “end of life “ “minimum charging current “ “long short-term memory“ are vague and a relative term that renders the claim indefinite. The terms “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “end of life“ “minimum charging current“ “long short-term memory“ 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 “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “end of life “ “minimum charging current“ “long short-term memory“ within the scope of the claim had been accomplished because nothing within the disclosure establishes when a sufficient “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “end of life“ “minimum charging current“ “long short-term memory“ occur. Regarding claim 10-11 the terms “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “similar neural network” “similar cell” are vague and a relative term that renders the claim indefinite. The terms “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “similar neural network” “similar cell” 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 “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “similar neural network” “similar cell” are vague and a relative term that renders the claim indefinite. The terms “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “similar neural network” “similar cell” within the scope of the claim had been accomplished because nothing within the disclosure establishes when a sufficient “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “similar neural network” “similar cell” are vague and a relative term that renders the claim indefinite. The terms “another measure value of state-of-health” “normal operation” “deep learning” ”degradation” “nominal capacity” “similar neural network” “similar cell” occur. Regarding claim 12 the term “deep learning” is vague and a relative term that renders the claim indefinite. The term “deep learning” is 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 “deep learning” within the scope of the claim had been accomplished because nothing within the disclosure establishes when a sufficient “deep learning” occurs. 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.

Step 2B, Does the claim recite additional element that amount to significantly more than the Judicial exception? There is no more additional element. Step 2B: No. claim 1 not eligible. Similar claims analysis for claim 2-9 as the dependent claims merely recite further data characterization and mathematical concepts that are part of the abstract idea, claims 2-9 not eligible as well.

The additional elements of a system comprising at least one device configured to make a local determination of at least one characteristic value of a battery cell, wherein the at least one device is further configured to supply to a neural network a time series of voltages and time, or another measure of a state-of-health indicator of a cell 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 a remote computation device, wherein the remote computation device comprises a similar neural network, wherein the neural network obtains data from ageing tests of at least one similar cell. and from determined voltages and time stamps, wherein a model of the remote computation device, thereby trained, is made available to the neural network of the at least one device 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 10 not eligible. Similar claim analysis for claim 11 as the dependent claims merely recite further data characterization and mathematical concepts that are part of the abstract idea, claim 11 not eligible as well.
