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 .
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 05/17/2023. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph:
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked.
As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph:
(A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function;
(B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and
(C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function.
Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function.
Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function.
Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action.
This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are:
“an acquisition module” as claimed in claim 5 stating “an acquisition module configured to acquire knowledge of a mechanism for LIB thermal runaway”.
“a structurized module” as claimed in claim 5 stating “a structurized module configured to decompose a triggering process of thermal runaway in LIB to obtain a structurized model”.
“a quantification module” as claimed in claim 5 stating “a quantification module configured to calculate a risk of thermal runaway in LIB”.
“a prediction module” as claimed in claim 5 stating “ a prediction module configured to take results from the quantification module as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway”.
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.
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.
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 5 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.
Claims 6-8 are dependent on claim 5, which is a system claim. However, claims 6-8 refers to “the method of claim 5”. It is unclear whether claims 6-8 are referring to system claim 5 or another method claim. Therefore, claims 6-8 fail to distinctly claim the subject matter and is indefinite. For the purposes of examination, claims 6-8 will refer to system claim 5. The examiner recommends the preamble of claims 6-8 to be amended to recite “The apparatus of claim 5…” to overcome this rejection under 35 U.S.C. 112(b).
Regarding claim 5, “an acquisition module configured to acquire knowledge of a mechanism for LIB thermal runaway; a structurized module configured to decompose a triggering process of thermal runaway in LIB to obtain a structurized model; a quantification module configured to calculate a risk of thermal runaway in LIB; and a prediction module configured to take results from the quantification module as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway” invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. In this instance, the corresponding structure refers to computer implemented means-plus function. The written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. The specification does not provide sufficient details of any structure that is used to implement the acquisition module, the structurized module, the quantification module, and the prediction module Therefore, the claim is indefinite and is rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Claims 6-8 inherit the rejection of claim 5 above.
Applicant may:
(a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph;
(b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or
(c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)).
If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either:
(a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or
(b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181.
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claim 5-8 rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
Regarding claim 5 “an acquisition module configured to acquire knowledge of a mechanism for LIB thermal runaway; a structurized module configured to decompose a triggering process of thermal runaway in LIB to obtain a structurized model; a quantification module configured to calculate a risk of thermal runaway in LIB; and a prediction module configured to take results from the quantification module as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway” as described above, does not provide adequate structure to perform the claimed function. (See 112(b) rejection above). Therefore, the specification does not appear to provide sufficient detail such that one of ordinary skill can reasonably conclude that the inventor had possession of the claimed invention. Claims 6-8 inherits the rejection of claim 5 above.
Claim Objections
Claim 1-8 objected to because of the following informalities:
All claims reference lithium-ion batteries as LIB. Claim 1 should first refer LIB as lithium-ion batteries, followed with (LIB) so that every LIB references in the claims are referring to lithium-ion batteries.
Appropriate correction is required.
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 rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more,
Regarding claim 1:
Subject Matter of Eligibility Analysis Step 1:
Claim 1 recites a method, which is directed to a process, and thus is one of the four statutory categories of patentable subject matter.
Subject Matter of Eligibility Analysis Step 2A Prong 1:
Claim 1 recites
perform risk quantification by using a Bayesian algorithm (this limitation is a mental process as it encompasses a human mentally calculating the risk quantification if a Bayesian algorithm was given).
mapping a fault tree structure to a dynamic Bayesian network model for thermal runaway in LIB to obtain quantitative results of a risk of thermal runaway in LIB (this limitation is a mental process as it encompasses a human mentally mapping a fault tree to a dynamic Bayesian network model).
Therefore, claim 1 recites an abstract idea.
Subject Matter of Eligibility Analysis Step 2A Prong 2:
Claim 1 further recites additional elements of
acquiring knowledge of a mechanism for thermal runaway in LIB (this element does not integrate the abstract idea into a practical application because it is merely data gathering, which is an insignificant extra-solution activity (see MPEP 2106.05(g))).
describing an evolution process of thermal runaway in LIB by adopting a fault tree (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
taking the quantitative results of a dynamic Bayesian network as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway in LIB (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
the fault tree being configured to systemically induce the knowledge of the mechanism for thermal runaway and graphically represent evolution of thermal runaway in LIB by virtue of events and a logic relationship therebetween (this element does not integrate an abstract idea because it recites a field of use limitation to apply a judicial exception (see MPEP 2106.05(h))).
the mapping being configured to convert the fault tree structure and parameters into the corresponding dynamic Bayesian network to represent a more complex node relationship, and perform risk quantification by using a Bayesian algorithm (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
the machine learning model referring to a support vector regression model configured to predict a trend of the risk of thermal runaway (this element does not integrate the abstract idea into a practical application because it recites a generic computing component on which to perform the abstract idea (see MPEP 2106.05(b))).
Therefore, claim 1 is not integrated into a practical application.
Subject Matter of Eligibility Analysis Step 2B:
The additional elements of claim 1 do not provide significantly more than the abstract idea itself, taken alone and in combination because
acquiring knowledge of a mechanism for thermal runaway in LIB is well understood, routine, and conventional. The court has ruled that “Receiving or transmitting data over a network, e.g., using the Internet to gather data” is recognized as a computer function that is well‐understood, routine, and conventional (buySAFE, Inc. v. Google, Inc., 765 F.3d 1350, 1355, 112 USPQ2d 1093, 1096 (Fed. Cir. 2014)).
describing an evolution process of thermal runaway in LIB by adopting a fault tree is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
taking the quantitative results of a dynamic Bayesian network as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway in LIB is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
the fault tree being configured to systemically induce the knowledge of the mechanism for thermal runaway and graphically represent evolution of thermal runaway in LIB by virtue of events and a logic relationship therebetween recites a field of use limitation to apply a judicial exception (see MPEP 2106.05(h)).
the mapping being configured to convert the fault tree structure and parameters into the corresponding dynamic Bayesian network to represent a more complex node relationship, and perform risk quantification by using a Bayesian algorithm is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
the machine learning model referring to a support vector regression model configured to predict a trend of the risk of thermal runaway uses a computer tool to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(b)).
Therefore, claim 1 is subject-matter ineligible.
Regarding claim 2:
Subject Matter of Eligibility Analysis Step 1:
Claim 2 recites a method, which is directed to a process, and thus is one of the four statutory categories of patentable subject matter.
Subject Matter of Eligibility Analysis Step 2A Prong 1:
Because claim 2 is dependent on claim 1, the Subject Matter of Eligibility Analysis Step 2A Prong 1 from claim 1 is applied here. Therefore claim 2 recites an abstract idea.
Subject Matter of Eligibility Analysis Step 2A Prong 2:
Claim 2 further recites additional elements of
utilizing the fault tree to analyze a triggering process of an accident for thermal runaway in LIB from two aspects of human and material factors by taking thermal runaway in LIB as a top event to obtain a fault tree model, wherein the human factor refers to emergency response failure for early abnormal heating-up, and the material factor refers to abnormal heating-up caused by mechanical abuse, electrical abuse, thermal abuse, etc. (this element does not integrate an abstract idea into a practical application because it recites a field of use limitation to apply a judicial exception (see MPEP 2106.05(h))).
Therefore, claim 2 is not integrated into a practical application
Subject Matter of Eligibility Analysis Step 2B:
The additional elements of claim 2 do not provide significantly more than the abstract idea itself, taken alone and in combination because
utilizing the fault tree to analyze a triggering process of an accident for thermal runaway in LIB from two aspects of human and material factors by taking thermal runaway in LIB as a top event to obtain a fault tree model, wherein the human factor refers to emergency response failure for early abnormal heating-up, and the material factor refers to abnormal heating-up caused by mechanical abuse, electrical abuse, thermal abuse, etc. recites a field of use limitation to apply a judicial exception (see MPEP 2106.05(h)).
Therefore, claim 2 is subject-matter ineligible.
Regarding claim 3:
Subject Matter of Eligibility Analysis Step 1:
Claim 3 recites a method, which is directed to a process, and thus is one of the four statutory categories of patentable subject matter.
Subject Matter of Eligibility Analysis Step 2A Prong 1:
Claim 3 recites
mapping the fault tree structure to the dynamic Bayesian network, which comprises graphic and numerical conversion: during graphic conversion, a top event, an intermediate event and a basic event of the fault tree are respectively mapped as a leaf node, an intermediate node and a root node of the Bayesian network, and the nodes are connected in the same way as the corresponding events (this limitation is a mental process as it encompasses a human mentally mapping the nodes from the fault tree to the nodes of the Bayesian network).
during numerical conversion, an occurrence probability of the basic event is taken as a prior probability of the corresponding root node, and a conditional probability table is adopted to represent a relationship between the nodes (this limitation is a mental process as it encompasses a human mentally mapping the probabilities of nodes).
Therefore, claim 3 recites an abstract idea.
Subject Matter of Eligibility Analysis Step 2A Prong 2:
Claim 3 further recites additional elements of
acquiring the prior probability and dependency between nodes of the dynamic Bayesian network according to multi-source information such as statistical data, an open data set, and expert knowledge to obtain Bayesian-inference-based quantitative results of the risk of thermal runaway in LIB (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
Therefore, claim 3 is not integrated into a practical application.
Subject Matter of Eligibility Analysis Step 2B:
The additional elements of claim 3 do not provide significantly more than the abstract idea itself, taken alone and in combination because
acquiring the prior probability and dependency between nodes of the dynamic Bayesian network according to multi-source information such as statistical data, an open data set, and expert knowledge to obtain Bayesian-inference-based quantitative results of the risk of thermal runaway in LIB is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
Therefore, claim 3 is subject-matter ineligible.
Regarding claim 4:
Subject Matter of Eligibility Analysis Step 1:
Claim 4 recites a method, which is directed to a process, and thus is one of the four statutory categories of patentable subject matter.
Subject Matter of Eligibility Analysis Step 2A Prong 1:
Claim 4 recites
dividing the quantitative results of the risk of thermal runaway of the dynamic Bayesian network into a training set and a test set (this limitation is a mental process as it encompasses a human mentally splitting data into subsets).
Therefore, claim 4 recites an abstract idea.
Subject Matter of Eligibility Analysis Step 2A Prong 2:
Claim 4 further recites additional elements of
taking the training set and the test set as inputs of the support vector regression model supporting parameter grid search to obtain the prediction results of the risk of thermal runaway (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
Therefore, claim 4 is not integrated into a practical application.
Subject Matter of Eligibility Analysis Step 2B:
The additional elements of claim 4 do not provide significantly more than the abstract idea itself, taken alone and in combination because
taking the training set and the test set as inputs of the support vector regression model supporting parameter grid search to obtain the prediction results of the risk of thermal runaway is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
Therefore, claim 4 is subject-matter ineligible.
Regarding claim 5:
Subject Matter of Eligibility Analysis Step 1:
Claim 5 recites an apparatus, which is directed to a machine, and thus is one of the four statutory categories of patentable subject matter.
Subject Matter of Eligibility Analysis Step 2A Prong 1:
Claim 5 recites
a quantification module configured to calculate a risk of thermal runaway in LIB (this limitation is a mental process as it encompasses a human mentally calculating the risk quantification if an algorithm was given).
Therefore, claim 5 recites an abstract idea.
Subject Matter of Eligibility Analysis Step 2A Prong 2:
Claim 5 further recites additional elements of
an acquisition module configured to acquire knowledge of a mechanism for LIB thermal runaway (this element does not integrate the abstract idea into a practical application because it is merely data gathering, which is an insignificant extra-solution activity (see MPEP 2106.05(g))).
a structurized module configured to decompose a triggering process of thermal runaway in LIB to obtain a structurized model (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
a prediction module configured to take results from the quantification module as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
an acquisition module configured to acquire knowledge of a mechanism for LIB thermal runaway (this element does not integrate the abstract idea into a practical application because it recites a generic computing component on which to perform the abstract idea (see MPEP 2106.05(b))).
a structurized module configured to decompose a triggering process of thermal runaway in LIB to obtain a structurized model (this element does not integrate the abstract idea into a practical application because it recites a generic computing component on which to perform the abstract idea (see MPEP 2106.05(b))).
a quantification module configured to calculate a risk of thermal runaway in LIB (this element does not integrate the abstract idea into a practical application because it recites a generic computing component on which to perform the abstract idea (see MPEP 2106.05(b))).
a prediction module configured to take results from the quantification module as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway (this element does not integrate the abstract idea into a practical application because it recites a generic computing component on which to perform the abstract idea (see MPEP 2106.05(b))).
Therefore, claim 5 is not integrated into a practical application.
Subject Matter of Eligibility Analysis Step 2B:
The additional elements of claim 5 do not provide significantly more than the abstract idea itself, taken alone and in combination because
an acquisition module configured to acquire knowledge of a mechanism for LIB thermal runaway is well understood, routine, and conventional. The court has ruled that “Receiving or transmitting data over a network, e.g., using the Internet to gather data” is recognized as a computer function that is well‐understood, routine, and conventional (buySAFE, Inc. v. Google, Inc., 765 F.3d 1350, 1355, 112 USPQ2d 1093, 1096 (Fed. Cir. 2014)).
a structurized module configured to decompose a triggering process of thermal runaway in LIB to obtain a structurized model is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
a prediction module configured to take results from the quantification module as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
an acquisition module configured to acquire knowledge of a mechanism for LIB thermal runaway is a generic component used to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(b)).
a structurized module configured to decompose a triggering process of thermal runaway in LIB to obtain a structurized model is a generic component used to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(b)).
a quantification module configured to calculate a risk of thermal runaway in LIB is a generic component used to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(b)).
a prediction module configured to take results from the quantification module as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway is a generic component used to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(b)).
Therefore, claim 5 is subject-matter ineligible.
Regarding claim 6:Subject Matter of Eligibility Analysis Step 1:
Claim 6 recites an apparatus, which is directed to a machine, and thus is one of the four statutory categories of patentable subject matter.
Subject Matter of Eligibility Analysis Step 2A Prong 1:
Claim 6 recites
utilizing the fault tree to analyze a triggering process of an accident for thermal runaway in LIB from two aspects of human and material factors by taking thermal runaway in LIB as a top event to obtain a fault tree model (this limitation is a mental process as it encompasses a human mentally mapping the nodes from the fault tree to the nodes of the Bayesian network).
Therefore, claim 6 recites an abstract idea.
Subject Matter of Eligibility Analysis Step 2A Prong 2:
Claim 6 does not further recite any additional elements. Therefore, claim 6 is not integrated into a practical application.
Subject Matter of Eligibility Analysis Step 2B:
Since there are not additional elements, claim 6 does not provide significantly more than the abstract idea itself, taken alone or in combination. Therefore, claim 6 is subject matter ineligible.
Regarding claim 7:
Subject Matter of Eligibility Analysis Step 1:
Claim 7 recites an apparatus, which is directed to a machine, and thus is one of the four statutory categories of patentable subject matter.
Subject Matter of Eligibility Analysis Step 2A Prong 1:
Claim 7 recites
the quantification module is configured to map a fault tree structure to a dynamic Bayesian network, which comprises graphic and numerical conversion: during graphic conversion, a top event, an intermediate event and a basic event of the fault tree are respectively mapped as a leaf node, an intermediate node and a root node of the Bayesian network, and the nodes are connected in the same way as the corresponding events (this limitation is a mental process as it encompasses a human mentally mapping the nodes from the fault tree to the nodes of the Bayesian network).
during numerical conversion, an occurrence probability of the basic event is taken as a prior probability of the corresponding root node, and a conditional probability table is adopted to represent a relationship between the nodes (this limitation is a mental process as it encompasses a human mentally mapping the probabilities of nodes).
Therefore, claim 7 recites an abstract idea.
Subject Matter of Eligibility Analysis Step 2A Prong 2:
Claim 7 further recites additional elements of
the quantification module is configured to map a fault tree structure to a dynamic Bayesian network, which comprises graphic and numerical conversion: during graphic conversion, a top event, an intermediate event and a basic event of the fault tree are respectively mapped as a leaf node, an intermediate node and a root node of the Bayesian network, and the nodes are connected in the same way as the corresponding events (this element does not integrate the abstract idea into a practical application because it recites a generic computing component on which to perform the abstract idea (see MPEP 2106.05(b))).
acquiring the prior probability and dependency between nodes within normal life of a battery in the dynamic Bayesian network from various channels such as statistical data, an open data set, and expert knowledge, and outputting quantitative results of the risk of thermal runaway in LIB (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
Therefore, claim 7 is not integrated into a practical application.
Subject Matter of Eligibility Analysis Step 2B:
The additional elements of claim 7 do not provide significantly more than the abstract idea itself, taken alone and in combination because
the quantification module is configured to map a fault tree structure to a dynamic Bayesian network, which comprises graphic and numerical conversion: during graphic conversion, a top event, an intermediate event and a basic event of the fault tree are respectively mapped as a leaf node, an intermediate node and a root node of the Bayesian network, and the nodes are connected in the same way as the corresponding events uses a generic computing tool to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(b)).
acquiring the prior probability and dependency between nodes within normal life of a battery in the dynamic Bayesian network from various channels such as statistical data, an open data set, and expert knowledge, and outputting quantitative results of the risk of thermal 12 runaway in LIB is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
Therefore, claim 7 is subject-matter ineligible.
Regarding claim 8:
Subject Matter of Eligibility Analysis Step 1:
Claim 8 recites an apparatus, which is directed to a machine, and thus is one of the four statutory categories of patentable subject matter.
Subject Matter of Eligibility Analysis Step 2A Prong 1:
Claim 8 recites
the prediction module is configured to divide the quantitative results of the risk of thermal runaway of the dynamic Bayesian network into a training set and a test set (this limitation is a mental process as it encompasses a human mentally splitting data into subsets).
Therefore, claim 8 recites an abstract idea.
Subject Matter of Eligibility Analysis Step 2A Prong 2:
Claim 8 further recites additional elements of
the prediction module is configured to divide the quantitative results of the risk of thermal runaway of the dynamic Bayesian network into a training set and a test set (this element does not integrate the abstract idea into a practical application because it recites a generic computing component on which to perform the abstract idea (see MPEP 2106.05(b))).
inputting the training set and the test set into a support vector regression model including parameter grid search to obtain the prediction results of the risk of thermal runaway (this element does not integrate the abstract idea into a practical application because it amounts to mere instructions to apply (see MPEP 2106.05(f))).
Therefore, claim 8 is not integrated into a practical application.
Subject Matter of Eligibility Analysis Step 2B:
The additional elements of claim 8 do not provide significantly more than the abstract idea itself, taken alone and in combination because
the prediction module is configured to divide the quantitative results of the risk of thermal runaway of the dynamic Bayesian network into a training set and a test set is a generic component used to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(b)).
inputting the training set and the test set into a support vector regression model including parameter grid search to obtain the prediction results of the risk of thermal runaway is an instruction to perform the abstract idea and cannot provide significantly more (see MPEP 2106.05(f)).
Therefore, claim 8 is subject-matter ineligible.
