Office Action

§101
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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement (IDS) submitted on 06/24/2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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 1-16 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-patentable subject matter. The claims are directed to an abstract idea without significantly more. Regarding claims 1-16, the independent claims (claims 1 and 16) are directed, in part, to an apparatus and a method for magnetic resonance numerical simulation. Step 1— First pursuant to step 1 in the January 2019 Guidance, claims 1-15 are directed to an apparatus, which falls under the statutory category of a machine and claim 16 is directed to a method comprising a series of steps which falls under the statutory category of a process. However, these claim elements are considered to be abstract ideas because they are directed to a mathematical concept which includes formulas or calculations. As per Step 2A – Prong 1 of the subject matter eligibility analysis, the claims are directed, in part, to inputting, in regard to an isochromat, a numerical value before update of magnetization, and a numerical value before update of a partial differential for the magnetization in each of a spatial direction and/or an angular frequency direction; and executing an arithmetic operation of an update formula representing a time-dependent behavior of magnetic resonance by using a part of the numerical values before update of the magnetization and the numerical values before update of the partial differential, and computing, in regard to the isochromat, a numerical value after update of the magnetization, and a numerical value after update of the partial differential for the magnetization in a computation target direction of the spatial direction and/or the angular frequency direction. If a claim limitation, under its broadest reasonable interpretation covers a formula or calculation, the it falls under the “mathematical concepts” grouping of abstract ideas. Accordingly, the claim recites an abstract idea. As per Step 2A – Prong 2 of the subject matter eligibility analysis, this judicial exception is not integrated into a practical application. In particular, independent claim 1 recites additional elements apparatus and processing circuitry, independent claim 16 is directed to a method and includes no additional elements. These additional element in both steps are recited at a high level of generality (i.e., as a generic device performing a generic computer function using a program) such that these elements amount no more than mere instructions to apply the exception using a generic computer component. Examiner looks to Applicant’s specification in at least Fig. 1 and [0017-0018] to understand that the invention may be implemented in a generic environment that “FIG. 1 is a diagram illustrating a configuration example of a magnetic resonance numerical simulation apparatus 1 according to a first embodiment. As illustrated in FIG. 1, the magnetic resonance numerical simulation apparatus 1 is a computer including processing circuitry 11, a communication device 12, a display device 13, an input device 14 and a storage device 15. Data communication between the processing circuitry 11, communication device 12, display device 13, input device 14 and storage device 15 is executed via a bus. The processing circuitry 11 includes a processor such as a CPU (Central Processing Unit). An input function 111, a numerical computation function 112 and an output control function 113 are implemented by the processor starting a magnetic resonance numerical simulation program installed in the storage device 15 or the like. The functions 111 to 113 are not necessarily implemented by single processing circuitry. A plurality of independent processors may be combined to constitute processing circuitry, and the respective processors may implement the functions 111 to 113 by executing the magnetic resonance numerical simulation program. In addition, the functions 111 to 113 may be implemented as modules constituting the magnetic resonance numerical simulation program, or may be implemented as individual hardware.” Examiner notes that because the specification describes the additional elements in general terms without describing the particulars, the claim limitations may be broadly but reasonably construed as reciting conventional computer components and techniques, particularly in light of Applicant’s’ specification, as cited in the instant office action. See Berkheimer Memo. The claims do not provide an inventive concept because the claims, in essence, merely recite various computer-based elements along with no more than mere instructions to implement the identified abstract idea using the computer-based elements. Accordingly, these additional elements do not integrate the abstract idea into a practical application because they are mere program instructions to implement the abstract idea on a computer. As per Step 2B of the subject matter eligibility analysis, the claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. The additional elements are mere instructions to apply the abstract idea on a computer. When considered individually, these claim elements only contribute generic recitations of technical elements to the claims. It is readily apparent, for example, that the claim is not directed to any specific improvements of these elements and the invention is not directed to a technical improvement. When the claims are considered individually and as a whole, the additional elements noted above, appear to merely apply the abstract concept to a technical environment in a very general sense. Their collective functions merely provide generic computer implementation. Therefore, when viewed as a whole, these additional claim elements do not provide meaningful limitations to transform the abstract idea into a practical application of the abstract idea or that amount to significantly more than the abstract idea itself. The most significant elements of the claims, that is the elements that really outline the inventive elements of the claims, are set forth in the elements identified as an abstract idea. The fact that the generic computing device is facilitating the abstract concept in not enough to confer statutory subject matter eligibility. The dependent claims further refine the abstract idea. These claims do not provide a meaningful linking to the judicial exception. Rather, these claims offer further descriptive limitations of elements found in the independent claims and addressed above. While these descriptive elements may provide further helpful context for the claimed invention these elements do not serve to confer subject matter eligibility to the invention since their individual and combined. Allowable Subject Matter Claims 1-16 are allowable over prior art but have pending rejections as indicated above. The claims would be allowable if rewritten to overcome the rejections. The following is a statement of reasons for the indication of allowable subject matter: Regarding claims 1 and 16, the prior art fails to specifically teach a magnetic resonance numerical simulation apparatus and method comprising processing circuitry configured to: input, in regard to an isochromat, a numerical value before update of magnetization, and a numerical value before update of a partial differential for the magnetization in each of a spatial direction and/or an angular frequency direction; and execute an arithmetic operation of an update formula representing a time-dependent behavior of magnetic resonance, by using a part of the numerical values before update of the magnetization, and the numerical values before update of the partial differential, and compute, in regard to the isochromat, a numerical value after update of the magnetization, and a numerical value after update of the partial differential for the magnetization in a computation target direction of the spatial direction and/or the angular frequency direction. Claims 2-15 depending from claim 1 are allowed for the same reasons, in combination with the limitations recited in their dependency. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Russell et al. (US Pat. 10,551,460) teaches a method of generating reproducible quantitative magnetic resonance data.
