DETAILED ACTION
Notice to Applicant
This communication is in response to the amendment submitted September 2, 2025. Claim 1 is amended. Claim 3 is cancelled (Claims 2, 16, and 17 were previously cancelled). Claims 1, 4 – 15,and 18 – 20 are pending.
Notice of Pre-AIA or AIA Status
The present application is being examined under the pre-AIA first to invent provisions.
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, 4 – 15,and 18 – 20 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.
Step One
Claims 1, 4 – 15,and 18 – 20 are drawn to a system and method, which is/are statutory categories of invention (Step 1: YES).
Step 2A Prong One
Independent claims 1 and 13 recite analyzing at least one medical image from a specified local population for a disease risk score and determine if it is calibrated for the local population comprising: receiving at least one input medical image; determining a disease risk score for the medical image; receiving the normalized distribution of disease risk scores taken over time; wherein the determination of sufficient data uses a statistical method to calculate the uncertainty in the calibration assessment and prevent it from being provided if the uncertainty is too high; and, outputting a disease risk score for the input medical image.
The recited limitations, as drafted, under their broadest reasonable interpretation, cover certain methods of organizing human activity, as reflected in the specification, which states that present invention “relates to the field of Computer Aided Diagnosis (CADx) systems and methods for assisting determination of medical images, used to support clinicians in healthcare. In particular, the field relates to risk Computer Aided Diagnosis systems, determination of whether a CADx system is calibrated, the calibration of the CADx system, where the CADx system assists the reading and reporting of medical images by radiologists and the interpretation of the radiologist's report by the physician responsible for patient care.” (paragraph 1 of the published specification). If a claim limitation, under its broadest reasonable interpretation, covers managing personal behavior or relationships or interactions between people, then it falls within the “Certain Methods of Organizing Human Activity” grouping of abstract ideas. The present claims cover certain methods of organizing human activity because this inventions addresses “two previously unrecognized needs for CADx devices, namely: an internal system to assess if the CADx device is uncalibrated to a local population,
and, given the device is uncalibrated, to optionally recalibrate it to a local population.
(paragraph 1 of the published specification). This problem is addressed by “recalibrating complex machine learning models, such as CNNs (convolutional neural networks). The invention is also able to identify when sufficient data from is available to perform each of these tasks.” (paragraph 47 of the published specification).
In addition, Claims 7 and 20, under their broadest reasonable interpretation, cover mathematical relationships, mathematical formulas or equations, or mathematical calculations, then it falls within the “Mathematical Concepts” grouping of abstract ideas.
Accordingly, the claims recite an abstract idea(s) (Step 2A Prong One: YES).”
Step 2A Prong Two
This judicial exception is not integrated into a practical application. The claims are abstract but for the inclusion of the additional elements including:
Claim 1: “Computer Aided Diagnosis System (CADx) system”, “input circuit”, “machine learning model”, “calibration auditor circuit”, “CADx system”, “wherein the calibration auditor circuit further comprises a safety lock that prevents outputting of the indication of the calibration state when there is insufficient CADx derived data to determine the calibration state”, “wherein the calibration auditor circuit further comprises a calibrator to recalibrate the CADx system when the calibration state is determined to be uncalibrated for the specified local population”, “output circuit”
Claim 4: “Computer Aided Diagnosis System (CADx) system”, “calibration auditor circuit”
Claims 5 – 6: “Computer Aided Diagnosis System (CADx) system”, “CADx system”
Claims 7 – 12: “Computer Aided Diagnosis System (CADx) system”
Claim 13: “Computer Aided Diagnosis System (CADx) system”, “CADx system”, “machine learning model”, “calibration auditor”
Claims 14 – 15, 20: “CADx”
Claim 18: “machine learning model”, “output module”, “score mapper”
Claim 19: “calibration auditor”, “CADx”
These features are additional elements that are recited at a high level of generality such that they amount to no more than mere instruction to apply the exception using generic computer components. See: MPEP 2106.05(f).
The additional elements are merely incidental or token additions to the claim that do not alter or affect how the process steps or functions in the abstract idea are performed. Therefore, the claimed additional elements do not add meaningful limitations to the indicated claims beyond a general linking to a technological environment. See: MPEP 2106.05(h).
The combination of these additional elements is no more than mere instructions to apply the exception using generic computer components. Accordingly, even in combination, these additional elements do not integrate the abstract idea into a practical application because they do not impose any meaningful limits on practicing the abstract idea.
Hence, the additional elements do not integrate the abstract idea into a practical application because they do not impose any meaningful limits on practicing the abstract idea. Accordingly, the claims are directed to an abstract idea (Step 2A Prong Two: NO).
Step 2B
The claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to integration of the abstract idea into a practical application, using the additional elements to perform the abstract idea amounts to no more than mere instructions to apply the exception using generic components. Mere instructions to apply an exception using a generic components cannot provide an inventive concept. See MPEP 2106.05(f).
Further, the claimed additional elements, identified above, are not sufficient to amount to significantly more than the judicial exception because they are generic components that are not integrated into the claim because they are merely incidental or token additions to the claim that do not alter or affect how the process steps or functions in the abstract idea are performed. Therefore, the claimed additional elements do not add meaningful limitations to the indicated claims beyond a general linking to a technological environment. See: MPEP 2106.05(h).
Further, the claimed additional elements, identified above, are not sufficient to amount to significantly more than the judicial exception because they are generic components that are configured to perform well-understood, routine, and conventional activities previously known to the industry. See: MPEP 2106.05(d). Said additional elements are recited at a high level of generality and provide conventional functions that do not add meaningful limits to practicing the abstract idea. The published specification supports this conclusion as follows:
[0098] The invention may be implemented in a computer program for running on a computer system, at least including code portions for performing steps of a method according to the invention when run on a programmable apparatus, such as a computer system or enabling a programmable apparatus to perform functions of a device or system according to the invention.
[0099] A computer program is a list of instructions such as a particular application program and/or an operating system. The computer program may for instance include one or more of: a subroutine, a function, a procedure, an object method, an object implementation, an executable application, an applet, a servlet, a source code, an object code, a shared library/dynamic load library and/or other sequence of instructions designed for execution on a computer system. Therefore, some examples describe a non-transitory Computer program product having executable program code stored therein for receiving at least one input medical image of a patient in which the patient's lungs are visible.
[0100] The computer program may be stored internally on a tangible and non-transitory computer readable storage medium or transmitted to the computer system via a computer readable transmission medium. All or some of the computer program may be provided on computer readable media permanently, removably or remotely coupled to an information processing system. The tangible and non-transitory computer readable media may include, for example and without limitation, any number of the following: magnetic storage media including disk and tape storage media; optical storage media such as compact disk media e.g., CD ROM, CD R, etc. and digital video disk storage media; non-volatile memory storage media including semiconductor-based memory units such as FLASH memory, EEPROM, EPROM, ROM; ferromagnetic digital memories; MRAM; volatile storage media including registers, buffers or caches, main memory, RAM, etc.
[0102] The computer system may for instance include at least one processing unit, associated memory and a number of input/output I/O devices. When executing the computer program, the computer system processes information according to the computer program and produces resultant output information via I/O devices.
Viewing the limitations as an ordered combination, the claims simply instruct the additional elements to implement the concept described above in the identification of abstract idea with routine, conventional activity specified at a high level of generality in a particular technological environment.
Hence, the claims as a whole, considering the additional elements individually and as an ordered combination, do not amount to significantly more than the abstract idea (Step 2B: NO).
Dependent claim(s) 4 – 14 and 18 – 20 when analyzed as a whole, considering the additional elements individually and/or as an ordered combination, are held to be patent ineligible under 35 U.S.C. 101 because the additional recited limitation(s) fail(s) to establish that the claim(s) is/are not directed to an abstract idea without significantly more. These claims fail to remedy the deficiencies of their parent claims above, and are therefore rejected for at least the same rationale as applied to their parent claims above, and incorporated herein.

Response to Arguments
Applicant's arguments filed September 2, 2025 have been fully considered but they are not persuasive. The Applicant’s arguments have been addressed in the order in which they were presented.
Claim Rejections - 35 USC § 101
The Applicant argues the amended claims include limitations having a concrete technical solution, citing example 39 of the Subject Matter Eligibility Examples. The Examiner respectfully disagrees. Example 39 recites “A computer-implemented method of training a neural network for facial detection comprising: collecting a set of digital facial images from a database; applying one or more transformations to each digital facial image including mirroring, rotating, smoothing, or contrast reduction to create a modified set of digital facial images; creating a first training set comprising the collected set of digital facial images, the modified set of digital facial images, and a set of digital non-facial images; training the neural network in a first stage using the first training set; creating a second training set for a second stage of training comprising the first training set and digital non-facial images that are incorrectly detected as facial images after the first stage of training; and training the neural network in a second stage using the second training set”, nothing in the claim precludes the step from practically being performed in the mind. The additional elements of Example 39 recite a specific manner of performing an iterative training algorithm, in which the system is retrained with an updated training set containing false positives introduced after face detection was performed on a set of non-facial images. The present claims differ such that the additional elements include “Computer Aided Diagnosis System (CADx) system”, “input circuit”, “machine learning model”, “calibration auditor circuit”, “CADx system”, “wherein the calibration auditor circuit further comprises a safety lock that prevents outputting of the indication of the calibration state when there is insufficient CADx derived data to determine the calibration state”, “wherein the calibration auditor circuit further comprises a calibrator to recalibrate the CADx system when the calibration state is determined to be uncalibrated for the specified local population”, “output circuit”. The claim, as a whole, merely describes how to generally “apply” the concept of reading and reporting of medical images by radiologists and the interpretation of the radiologist’s report by the physician responsible for patient care (as described in the Applicant’s specification). In addition, the specification does not disclose training or machine learning. The claimed computer components are recited at a high level of generality and are merely invoked as tools to perform an existing medical records update process. Simply implementing the abstract idea on a generic computer is not a practical application of the abstract idea. The Applicant’s published specification recites:
[0098] The invention may be implemented in a computer program for running on a computer system, at least including code portions for performing steps of a method according to the invention when run on a programmable apparatus, such as a computer system or enabling a programmable apparatus to perform functions of a device or system according to the invention.
[0099] A computer program is a list of instructions such as a particular application program and/or an operating system. The computer program may for instance include one or more of: a subroutine, a function, a procedure, an object method, an object implementation, an executable application, an applet, a servlet, a source code, an object code, a shared library/dynamic load library and/or other sequence of instructions designed for execution on a computer system. Therefore, some examples describe a non-transitory Computer program product having executable program code stored therein for receiving at least one input medical image of a patient in which the patient's lungs are visible.
[0100] The computer program may be stored internally on a tangible and non-transitory computer readable storage medium or transmitted to the computer system via a computer readable transmission medium. All or some of the computer program may be provided on computer readable media permanently, removably or remotely coupled to an information processing system. The tangible and non-transitory computer readable media may include, for example and without limitation, any number of the following: magnetic storage media including disk and tape storage media; optical storage media such as compact disk media e.g., CD ROM, CD R, etc. and digital video disk storage media; non-volatile memory storage media including semiconductor-based memory units such as FLASH memory, EEPROM, EPROM, ROM; ferromagnetic digital memories; MRAM; volatile storage media including registers, buffers or caches, main memory, RAM, etc.
[0102] The computer system may for instance include at least one processing unit, associated memory and a number of input/output I/O devices. When executing the computer program, the computer system processes information according to the computer program and produces resultant output information via I/O devices.
Accordingly, the claim as a whole does not integrate the abstract idea into a practical application because they do not impose any meaningful limits on practicing the abstract idea. Thus, the Applicant’s argument is not persuasive and the rejection is maintained.
The Applicant argues the amended claims do not recite a judicial exception, but rather represents a concrete application of technological principles to solve real-world challenges. The Examiner respectfully disagrees. The Examiner submits in Enfish, for example, the Court found that "the claims at issue focused not on asserted advances in uses to which existing computer capabilities could be put, but on a specific improvement in how computer could carry out one of their basic functions of storage and retrieval of data”. Here, the focus of the claims is not on such an improvement in computers as tools, but on abstract ideas that use computers as tools. The claims here do not require any nonconventional computer, network or display components, or even a "non-conventional and non-generic arrangement of known, conventional pieces”. This conclusion is supported by the Applicant’s published specification supports this conclusion as follows:
[0098] The invention may be implemented in a computer program for running on a computer system, at least including code portions for performing steps of a method according to the invention when run on a programmable apparatus, such as a computer system or enabling a programmable apparatus to perform functions of a device or system according to the invention.
[0099] A computer program is a list of instructions such as a particular application program and/or an operating system. The computer program may for instance include one or more of: a subroutine, a function, a procedure, an object method, an object implementation, an executable application, an applet, a servlet, a source code, an object code, a shared library/dynamic load library and/or other sequence of instructions designed for execution on a computer system. Therefore, some examples describe a non-transitory Computer program product having executable program code stored therein for receiving at least one input medical image of a patient in which the patient's lungs are visible.
[0100] The computer program may be stored internally on a tangible and non-transitory computer readable storage medium or transmitted to the computer system via a computer readable transmission medium. All or some of the computer program may be provided on computer readable media permanently, removably or remotely coupled to an information processing system. The tangible and non-transitory computer readable media may include, for example and without limitation, any number of the following: magnetic storage media including disk and tape storage media; optical storage media such as compact disk media e.g., CD ROM, CD R, etc. and digital video disk storage media; non-volatile memory storage media including semiconductor-based memory units such as FLASH memory, EEPROM, EPROM, ROM; ferromagnetic digital memories; MRAM; volatile storage media including registers, buffers or caches, main memory, RAM, etc.
[0102] The computer system may for instance include at least one processing unit, associated memory and a number of input/output I/O devices. When executing the computer program, the computer system processes information according to the computer program and produces resultant output information via I/O devices.
Further the claims, unlike Enfish, use existing computers as tools in aid of processes focused on abstract ideas. Thus, Applicant’s argument is not persuasive and the rejection is maintained.
The Applicant argues the amended claims integrate any alleged abstract concept into a practical application that improves the technical reliability and safety of medical imaging systems. The Examiner respectfully disagrees. The additional elements of the present claims fail to integrate the exception into a practical application of the exception. The 2019 PEG defines the phrase “integration into a practical application” to require an additional element or a combination of additional elements in the claim to apply, rely on, or use the judicial exception in a manner that imposes a meaningful limit on the judicial exception, such that it is more than a drafting effort designed to monopolize the exception. For example, the 2019 PEG guidelines recite limitations that are indicative of integration into a practical application when recited in a claim with a judicial exception include:
Improvements to the functioning of a computer, or to any other technology or technical field, as discussed in MPEP 2106.05(a);
Applying or using a judicial exception to effect a particular treatment or prophylaxis for disease or medical condition – see Vanda Memo
Applying the judicial exception with, or by use of, a particular machine, as discussed in MPEP 2106.05(b);
Effecting a transformation or reduction of a particular article to a different state or thing, as discussed in MPEP 2106.05(c); and
Applying or using the judicial exception in some other meaningful way beyond generally linking the use of the judicial exception to a particular technological environment, such that the claim as a whole is more than a drafting effort designed to monopolize the exception, as discussed in MPEP 2106.05(e) and the Vanda Memo issued in June 2018.
The present claims fail to demonstrate an improvement to the functioning of a computer or to any other technology or technical field. Thus, Applicant’s argument is not persuasive, and the rejection is maintained.
