Office Action

§101
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s claim amendment overcome the 35 U.S.C. 112(b) rejection of claims 1-8. Applicant’s arguments with respect to claims have been considered but are moot because the new ground of rejection in response to applicant’s claims amendment currently presented. 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 1-8 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. Regarding claim 1: 1. (Currently amended) A partial discharge determination apparatus that determines partial discharge occurring in a power transmission facility, the partial discharge determination apparatus comprising: a central processing unit (CPU) configured to: acquire measurement data representing a charge amount and a phase of each partial discharge occurring in the power transmission facility; remove or reduce noise included in the measurement data based on statistical information; generate ᵠ-q-n data representing a charge amount, a phase, and the number of pulses of each of the partial discharge and the noise included in the measurement data from the measurement data from which the noise has been removed or reduced; generate a learning model by performing machine learning using the ᵠ-q-n data of the partial discharge and the noise; and determine whether at least the partial discharge has occurred by using the learning model based on the generated ᵠ-q-n data. Analysis Steps for claim 1: Step 1: Is claim 1 claim to a process, machine, manufacture or composition of matter? Yes, claim 1 recites a partial discharge determination apparatus which is within one of the 4 statutory categories the process, machine, manufacture or composition of matter. Step 2a) Prong One: Does claim 1 recite an abstract idea, law of nature, or natural phenomenon? Yes, claim 1 recites “remove or reduce noise included in the measurement data based on statistical information” may be implemented by mathematical operations using statistical information, and this mental step a person can review the phase and charge data to decide what is noise and remove it from the data (41 in fig. 3); therefore, mathematical operations are abstract idea. Yes, claim 1 recites “generate ᵠ-q-n data representing a charge amount, a phase, and the number of pulses of each of the partial discharge and the noise included in the measurement data from the measurement data from which the noise has been removed or reduced” which is mathematic and graphing (42, 43 in fig. 3) and may be generated from a computer program implemented using mathematical operations and/or human mental activities, and/or using statistical information; therefore, mathematical operations and/or human mental activities are abstract idea Yes, claim 1 recites “generates a learning model by performing machine learning using the ᵠ-q-n data of the partial discharge and the noise” is generated from a computer program implemented using mathematical operations/algorithm, and/or human mental activities; therefore, mathematical operations/algorithm and/or human mental activities are abstract idea. Yes, claim 1 recites “determine whether at least the partial discharge has occurred by using the learning model based on the generated ᵠ-q-n data” is determined from a computer program implemented using human mental activities which may be a result of the computer program, or in alternative a mental step of reviewing the data and mentally deciding there is a discharge; therefore, human mental activities are abstract idea. Step 2a) Prong Two: Does claim 1 recite additional element that integrate the Judicial Exception into a Practical Application? No, claim 1 recites additional element “A partial discharge determination apparatus that determines partial discharge occurring in a power transmission facility, the partial discharge determination apparatus comprising: a central processing unit (CPU” which does not integrate the Judicial Exception into a Practical Application because the partial discharge determination 6 is implement by a general-purpose computer device including a central processing unit (CPU) 30 and a memory 31, a storage device 32 (e.g. as described in fig. 3 of applicant’s drawing and [0031] of applicant’s specification with receipt date 09/29/2023) and using the general-purpose computer device in a power transmission facility does not impose any meaningful limits on practicing the abstract ideas. Step 2b): Does claim 1 recite additional elements that amount to significantly more than the Judicial Exception? No, using a general-purpose computer device including general components does not integrate such abstract ideas (the mathematical operations and/or human mental activities) into a practical application. When considering claim 1 as a whole, it does not amount to significantly more than judicial exception. Therefore, claim 1 is not eligible subject matter under 35 U.S.C. 101.

Regarding claim 5: 5. (Currently amended) A partial discharge determination method executed in a partial discharge determination apparatus, which includes a central processing unit (CPU) that determines partial discharge occurring in a power transmission facility, the partial discharge determination method, executed by the CPU, comprising: a first step of acquiring measurement data representing a charge amount and a phase of each partial discharge occurring in the power transmission facility; a second step of removing or reducing noise included in the measurement data based on statistical information; a third step of generating ᵠ-q-n data representing a charge amount, a phase, and the number of pulses of each of the partial discharge and the noise included in the measurement data from the measurement data from which the noise has been removed or reduced; and a fourth step of determining whether or not at least the partial discharge has occurred by using a learning model generated by performing machine learning using the ᵠ-q-n data of the partial discharge and the noise based on the ᵠ-q-n data. Analysis Steps for claim 5: Step 1: Is claim 5 claim to a process, machine, manufacture or composition of matter? Yes, claim 5 recites a partial discharge determination method which is within one of the 4 statutory categories the process, machine, manufacture or composition of matter. Step 2a) Prong One: Does claim 5 recite an abstract idea, law of nature, or natural phenomenon? Yes, claim 5 recites “a second step of removing or reducing noise included in the measurement data based on statistical information” may be performed by mathematical operations using statistical information, and this mental step a person can review the phase and charge data to decide what is noise and remove it from the data (41 in fig. 3); therefore, mathematical operations are abstract idea. Yes, claim 5 recites “a third step of generating ᵠ-q-n data representing a charge amount, a phase, and the number of pulses of each of the partial discharge and the noise included in the measurement data from the measurement data from which the noise has been removed or reduced” which is mathematic and graphing (42, 43 in fig. 3) and may be performed by mathematical operations and/or human mental activities, and/or using statistical information; therefore, mathematical operations and/or human mental activities are abstract idea Yes, claim 5 recites “a fourth step of determining whether or not at least the partial discharge has occurred by using a learning model generated by performing machine learning using the ᵠ-q-n data of the partial discharge and the noise based on the ᵠ-q-n data”, where “a learning model generated by performing machine learning using the ᵠ-q-n data of the partial discharge and the noise based on the ᵠ-q-n data” is generated from a computer program implemented using mathematical operations/algorithm and/or human mental activities; therefore, mathematical operations/algorithm and/or human mental activities are abstract idea; therefore; “a fourth step of determining whether or not at least the partial discharge has occurred by using a learning model generated by performing machine learning using the ᵠ-q-n data of the partial discharge and the noise based on the ᵠ-q-n data” is determined from the computer program implemented using mathematical operations and/or human mental activities; therefore, mathematical operations and/or human mental activities are abstract idea. Step 2a) Prong Two: Does claim 5 recite additional element that integrate the Judicial Exception into a Practical Application? No, claim 5 recites additional element “a partial discharge determination apparatus, which includes a central processing unit (CPU) that determines partial discharge occurring in a power transmission facility” which does not integrate the Judicial Exception into a Practical Application because the partial discharge determination 6 is implement by a general-purpose computer device including a central processing unit (CPU) 30 and a memory 31, a storage device 32 (e.g. described in fig. 3 of applicant’s drawing and [0031] of applicant’s specification with receipt date 09/29/2023) and using the general-purpose computer device in a power transmission facility does not impose any meaningful limits on practicing the abstract ideas. Step 2b): Does claim 5 recite additional elements that amount to significantly more than the Judicial Exception? No, using a general-purpose computer device including general components does not integrate such abstract ideas (the mathematical operations and/or human mental activities) into a practical application. When considering claim 5 as a whole, it does not amount to significantly more than judicial exception. Therefore, claim 5 is not eligible subject matter under 35 U.S.C. 101.
