Office Action

§101 §103 §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 . 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 1-11, 13-24 and 26 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claims recite mental processes of judgement and evaluation. This judicial exception is not integrated into a practical application or amount to significantly mare as the additional elements are links to technologic field in combination of generic computer functions that are implemented to perform the disclosed abstract idea above. See the below analysis for further details. Claims 1 and 14 Step 1: The claim recites a method and system, therefore, it falls into the statutory category of a method and apparatus. Step 2A Prong 1: The claim recites, inter alia: (b) Comparing performance of the machine learning system on the training data set to performance of the machine learning system on a development data set, (This amounts to a mental process of judgment and evaluation wherein a user compares the performance or result of two systems.) (c) upon identification of a difference beyond a threshold between performance of the machine learning system on the training data set and performance of the machine learning system on the development data set, increasing a hyperparameter used in machine learning system, wherein the regularization hyperparameter weights an auxiliary objective that is evaluated on a latent representation; (This amounts to a mental process of observation, judgment and evaluation wherein a user compares the difference between the results of two systems to a threshold and increases a parameter if it is above the threshold.) (d) validating performance of the machine learning system (This amounts to a mental process of judgment and evaluation wherein a user validates system results and being correct or accurate.) repeating steps (b)-(d) iteratively until a stopping criterion is satisfied. (This is a mental step wherein a user repeats the process of comparing results of two systems, and when they are different adjusted a parameter of the system until they match, at which point the user stops.) Step 2A Prong 2: This judicial exception is no integrated into a practical application. Aside from the limitations above, the claim recites: training, by a programmed computer system comprising one or more processor cores, the machine learning system, through machine learning, on a training data set; (This amounts to using a generic computer hardware (computer, processors, and machine learning models) to implement the abstract idea, see MPEP 2106.05(f). This is the case because the machine learning models and training is cited at high level of generality.) wherein the development data set is distinct from the training data set; (This is amounts to linking the abstract idea to technological field, see MPEP 2106.05(h).) re-training, by the programmed computer system, the machine learning system, wherein re-training the machine learning system comprises a regularization hyperparameter evaluated on during training; (This amounts to using a generic computer hardware (computer, processors, and machine learning models) to implement the abstract idea, see MPEP 2106.05(f). This is the case because the machine learning models and training is cited at high level of generality.) wherein the validation data set is distinct from both the training data set and the development data set; and (this amounts to extra-solution activity of a particular type of data to used and/or manipulated, see MPEP 2106.05(g) and linking to particular technological field (machine learning), see MPEP 2106.05(h).) one or more processor cores; and computer memory in communication the one or more processor cores, wherein the computer memory stores instructions that when executed by the one or more processor cores causes the one or more process cores; (claim 14) (This amount to using generic computer hardware to implement the abstract idea, see MPEP 2106.05(f).) The additional elements as disclosed above alone or in combination do not integrate the judicial exception into practical application as they are mere insignificant extra solution activity in combination of generic computer functions that are implemented to perform the disclosed abstract idea above. Step 2B: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. The additional elements of: “training, by a programmed computer system comprising one or more processor cores, the machine learning system, through machine learning, on a training data set; and re-training, by the programmed computer system, the machine learning system, wherein re-training the machine learning system comprises a regularization hyperparameter evaluated on during training;” amounts to using a generic computer hardware (computer, processors, and machine learning models) to implement the abstract idea, see MPEP 2106.05(f). This is the case because the machine learning models and training is cited at high level of generality. The additional limitations of “wherein the development data set is distinct from the training data set; and wherein the validation data set is distinct from both the training data set and the development data set;” amounts to linking the abstract idea to technological field, as training data, development data and validation sets are common in the machine learning technology, see MPEP 2106.05(h). The additional elements as disclosed above in combination of the abstract idea are not sufficient to amount to significantly more than the judicial exception as they are links to technologic field in combination of generic computer functions that are implemented to perform the disclosed abstract idea above. Claims 2 and 15 Step 2A Prong 1: The claim recites, inter alia: Claim 2 and 15 inherit the abstract idea of claims 1 and 14. Step 2A Prong 2: This judicial exception is no integrated into a practical application. Aside from the limitations above, the claim recites: wherein increasing the regularization hyperparameter used in the re-training the machine learning system comprises additionally increasing a L1 regularization hyperparameter used in the re-training the machine learning system. (Adding the words “apply it” (or an equivalent) with the judicial exception, or mere instructions to implement an abstract idea on a computer, or merely uses a computer as a tool to perform an abstract idea - see MPEP 2106.05(f) – Examiner’s note: high level recitation of training a machine learning model by changing a model parameter.) The additional elements as disclosed above alone or in combination do not integrate the judicial exception into practical application as they are mere insignificant extra solution activity in combination of generic computer hardware performing generic functions that are implemented to perform the disclosed abstract idea above. Step 2B: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. The additional element are: “wherein increasing the regularization hyperparameter used in the re-training the machine learning system comprises additionally increasing a L1 regularization hyperparameter used in the re-training the machine learning system” which are cited at high level of generality and result in using the machine learning model a tool to implement the abstract idea, see MPEP 2106.05(f). The additional elements as disclosed above in combination of the abstract idea are not sufficient to amount to significantly more than the judicial exception as they are well, understood, routine and conventional activity as disclosed in combination of generic computer hardware performing generic functions that are implemented to perform the disclosed abstract idea above. Claim 15 is the system embodiment of claim 2 with similar limitations and thus rejected using the reasoning found in claim 2. Claims 3 and 16 Step 2A Prong 1: The claim recites, inter alia: Claim 3 and 16 inherit the abstract idea of claims 1 and 14. Step 2A Prong 2: This judicial exception is no integrated into a practical application. Aside from the limitations above, the claim recites: wherein increasing the regularization hyperparameter used in the re-training the machine learning system comprises additionally increasing a L2 regularization hyperparameter used in the re-training the machine learning system. (Adding the words “apply it” (or an equivalent) with the judicial exception, or mere instructions to implement an abstract idea on a computer, or merely uses a computer as a tool to perform an abstract idea - see MPEP 2106.05(f) – Examiner’s note: high level recitation of training a machine learning model by changing a model parameter.) The additional elements as disclosed above alone or in combination do not integrate the judicial exception into practical application as they are mere insignificant extra solution activity in combination of generic computer hardware performing generic functions that are implemented to perform the disclosed abstract idea above. Step 2B: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. The additional element are: “wherein increasing the regularization hyperparameter used in the re-training the machine learning system comprises additionally increasing a L2 regularization hyperparameter used in the re-training the machine learning system” which are cited at high level of generality and result in using the machine learning model a tool to implement the abstract idea, see MPEP 2106.05(f). The additional elements as disclosed above in combination of the abstract idea are not sufficient to amount to significantly more than the judicial exception as they are well, understood, routine and conventional activity as disclosed in combination of generic computer hardware performing generic functions that are implemented to perform the disclosed abstract idea above. Claim 16 is the system embodiment of claim 3 with similar limitations and thus rejected using the reasoning found in claim 3. Claims 4 and 17 Step 2A Prong 1: The claim recites, inter alia: Claim 4 and 17 inherit the abstract idea of claims 1 and 14. Step 2A Prong 2: This judicial exception is no integrated into a practical application. Aside from the limitations above, the claim recites: the machine learning system comprises a plurality of asynchronous agents, where each of the plurality of asynchronous agents utilizes a feature vector, and wherein each of the plurality of asynchronous agents is trained with respect to performance objective; (this amounts to using generic hardware to execute the abstract idea, wherein the asynchronous agents are generic computer components, see MPEP 2106.05(f).) the latent representation of the machine learning model comprises the feature vectors; (This amount to linking the abstract idea to a particular field of technology, see MPEP 2106.05(h).)

The additional element are: “the machine learning system comprises a plurality of asynchronous agents, where each of the plurality of asynchronous agents utilizes a feature vector, and wherein each of the plurality of asynchronous agents is trained with respect to performance objective” which amounts to using generic hardware to execute the abstract idea, wherein the asynchronous agents are generic computer components, see MPEP 2106.05(f). Also, the limitation of “the latent representation of the machine learning model comprises the feature vectors;” amount to linking the abstract idea to a particular field of technology, see MPEP 2106.05(h). The additional elements as disclosed above in combination of the abstract idea are not sufficient to amount to significantly more than the judicial exception as generic computer hardware performing generic functions that are implemented to perform the disclosed abstract idea above. Claim 17 is the system embodiment of claim 4 with similar limitations and thus is rejected using the same reasoning as claim 4. Claim 17 also has the added limitations of a computer memory storing instructions that are executed by a one or more processors. These addition elements amount to using generic computer hardware to execute the abstract idea, see MPEP 2106.05(f).

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 1-11, 13-24 and 26 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. Claim 1 has the term “auxiliary objective” which renders claim 1 as indefinite. When looking to the instant specification for the meaning of the term “auxiliary objective”, the examiner could not find a mention of it. Also, as there is an “auxiliary objective”, it would indicate there is a primary or main objection which also I not defined in the specification and claims. As such it not clear to examiner what is meant or what is need to meet the limitation so the term “auxiliary objective”, and thus the claim is found to be indefinite. Also, independent claim 14 has the issues with the term “auxiliary objective. As claims 1 and 14 are found to be indefinite are too are all the claims dependent on them which are claims 2-11, 13, 15-24 and 26. Response to Arguments Applicant's arguments filed 10 February 2026 have been fully considered but they are not persuasive. The applicant argues that claims do not recite a mathematical concept, but instead recite a specific machine implemented training control. Applicant further argues that the abstract of mathematical concept is integrated into a practical application as the claimed feedback-control architecture integrates any mathematical computation into a practical application that improves how the machine learning system trains and generalizes. Applicant also argues the claims do not include a mental process as training neural network cannot be practically performed in human mind, and that the amended claims overcome the rejection under 35 USC 103. The examiner respectfully traverses the applicant’s arguments for the following reason: The examiner maintains that claims do disclose an abstract idea of a mental process and points out that the abstract idea of a mathematical concept was not stated by the examiner. For claim 1 the abstract idea is a mental process of observation, evaluation and judgment. The abstract ideas in claim1 and 14 are: ((b) Comparing performance of the machine learning system on the training data set to performance of the machine learning system on a development data set, (This amounts to a mental process of judgment and evaluation wherein a user compares the performance or result of two systems.) (c) upon identification of a difference beyond a threshold between performance of the machine learning system on the training data set and performance of the machine learning system on the development data set, increasing a hyperparameter used in machine learning system, wherein the regularization hyperparameter weights an auxiliary objective that is evaluated on a latent representation; (This amounts to a mental process of observation, judgment and evaluation wherein a user compares the difference between the results of two systems to a threshold and increases a parameter if it is above the threshold.) (d) validating performance of the machine learning system (This amounts to a mental process of judgment and evaluation wherein a user validates system results and being correct or accurate.) repeating steps (b)-(d) iteratively until a stopping criterion is satisfied. (This is a mental step wherein a user repeats the process of comparing results of two systems, and when they are different adjusted a parameter of the system until they match, at which point the user stops.) These limitations are mental processes of observation, judgment and evaluation of comparing the performance of system on a training data and development data, comparing the different to a threshold, increasing a hyperparameter when the threshold is exceeded, and validating the performance. All of these steps can be performed by a user, and the act of repeatedly doing it can also be done by a user. Thus, the examiner maintains that the claims do contain an abstract idea. Applicant further argues that claims are an improvement the functioning of computer but the examiner respectfully traverses this argument as the claims are not an improvement the functioning of a computer but an abstract idea being implemented using generic computer hardware. The remaining limitations of claim do not integrate the abstract into a practical application. The remaining limitations are: training, by a programmed computer system comprising one or more processor cores, the machine learning system, through machine learning, on a training data set; (This amounts to using a generic computer hardware (computer, processors, and machine learning models) to implement the abstract idea, see MPEP 2106.05(f). This is the case because the machine learning models and training is cited at high level of generality.) wherein the development data set is distinct from the training data set; (This is amounts to linking the abstract idea to technological field, see MPEP 2106.05(h).) re-training, by the programmed computer system, the machine learning system, wherein re-training the machine learning system comprises a regularization hyperparameter evaluated on during training; (This amounts to using a generic computer hardware (computer, processors, and machine learning models) to implement the abstract idea, see MPEP 2106.05(f). This is the case because the machine learning models and training is cited at high level of generality.) wherein the validation data set is distinct from both the training data set and the development data set; and (this amounts to extra-solution activity of a particular type of data to used and/or manipulated, see MPEP 2106.05(g) and linking to particular technological field (machine learning), see MPEP 2106.05(h).) one or more processor cores; and computer memory in communication the one or more processor cores, wherein the computer memory stores instructions that when executed by the one or more processor cores causes the one or more process cores; (claim 14) (This amount to using generic computer hardware to implement the abstract idea, see MPEP 2106.05(f).) All of the above limitations do not integrate do not integrate the judicial exception into practical application as they are mere insignificant extra solution activity in combination of generic computer functions that are implemented to perform the disclosed abstract idea. For these the reason the examiner maintains the rejection under 35 USC 101 for being abstract idea. The rejection under 35 USC 103 should be withdrawn in light of the amendment to the claims as none of the references disclose the amended limitation. The examiner agrees that prior art references do not disclose claim 1 and 14 as amended and withdraws the rejection under 35 USC 103. Conclusion A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
