Claim(s) 1, 3-5, 7-10, 12, 14, 16, 18-19 is/are currently amended. Claim(s) 2, 15 is/are cancelled. Claim(s) 1, 3-14, 16-19 is/are pending. Claim(s) 1, 3-14, 16-19 is/are rejected. 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 . Response to Arguments Applicant's arguments regarding the objections to the claims have been fully considered and, in light of the amendments to the claims, are persuasive. Applicant's arguments regarding the 35 U.S.C. 112(b) rejection(s) of claim(s) 1, 3- 14, 16-19 have been fully considered and, in light of the amendments to the claims, are persuasive. The 35 U.S.C. 112(b) rejection(s) of claim(s) 1, 3- 14, 16-19 has/have been withdrawn. Applicant’s arguments regarding the 35 U.S.C. 101 rejection of the claims are based on the newly amended subject matter. All arguments are addressed in the 35 U.S.C. 101 rejection of the claims below. 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. Claim(s) 1, 3-14, 16-19 is/are rejected under 35 U.S.C. 101, because the claim(s) is/are directed to an abstract idea, and because the claim elements, whether considered individually or in combination, do not amount to significantly more than the abstract idea, see Alice Corporation Pty. Ltd. V. CLS Bank International et al., 573 US 208 (2014). Regarding claim 1, the claim is rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Step 1 Analysis: Claim 1 is directed to a method, which is directed to a process, one of the statutory categories. Step 2A Prong One Analysis: The claim recites a(n) model compression method. The limitation of adding ... an internal classification layer to each encoder layer of an input model, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. The limitation of freezing ... a weight of the input model to a constant, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. The limitation of measuring ... performance for an output of each internal classification layer, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. The limitation of determining ... an encoder layer in which the measured performance is lower than performance of the input model by a preset performance drop tolerance range or more, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. The limitation of pruning ... upper encoder layers of a final layer which is an upper layer of the determined encoder layer, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. If a claim limitation, under its broadest reasonable interpretation, covers performance of the limitation in the mind, then it falls within the "Mental Processes" grouping. Accordingly, the claim recites an abstract idea. Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. The claim recites additional element(s) – computer device, at least one processor. The additional element(s) is/are recited at a high-level of generality (i.e., as generic computer components performing generic computer functions of executing instructions on the computers) such that it amounts to no more than mere instructions to apply the exception using generic computer components (MPEP 2106.05(b)). The claim recites additional element(s) – input model. The additional element(s) is/are recited at a high-level of generality such that it amounts to no more than indicating a field of use or technological environment in which to apply the judicial exception (MPEP 2106.05(h)). The claim recites simultaneously training, by the at least one processor, each internal classification layer added to each encoder layer for a target task which is simply generic training to perform the abstract idea of model generation and amounts to mere instructions to apply the exception (MPEP 2106.05(f)). Accordingly, the additional element(s) do(es) not integrate the abstract idea into a practical application because the additional element(s) do(es) not impose any meaningful limits on practicing the abstract idea, and, therefore, the claim is directed to an abstract idea. Step 2B Analysis: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to the integration of the abstract idea into a practical application, the additional element(s) of: computer device, at least one processor amount(s) to no more than mere instructions to apply the exception using generic computer components (MPEP 2106.05(b)) generic training to perform the abstract idea amount(s) to no more than mere instructions to apply the exception (MPEP 2106.05(f)) input model amount(s) to no more than indicating a field of use or technological environment in which to apply the judicial exception (MPEP 2106.05(h)) The additional element(s) do(es) not provide an inventive concept, and, therefore, the claim is not patent eligible. Regarding claim 3, the claim is rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Step 1 Analysis: Claim 3 is directed to a method, which is directed to a process, one of the statutory categories. Step 2A Prong One Analysis: The claim recites a(n) model compression method. The Step 2A Prong One Analysis for claim 1 is applicable here since claim 3 carries out the method of claim 1 but for the recitation of additional element(s) of wherein the simultaneously training comprises simultaneously training the internal classification layer added to each encoder layer using a cross-entropy loss function. Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. The claim recites wherein the simultaneously training comprises simultaneously training the internal classification layer added to each encoder layer using a cross-entropy loss function which is simply additional information regarding the training, and the element(s) do(es) not apply the exception in a meaningful way (MPEP 2106.05(e)). The claim recites additional element(s) – cross-entropy loss function. The additional element(s) is/are recited at a high-level of generality such that it amounts to no more than indicating a field of use or technological environment in which to apply the judicial exception (MPEP 2106.05(h)). Accordingly, the additional element(s) do(es) not integrate the abstract idea into a practical application because the additional element(s) do(es) not impose any meaningful limits on practicing the abstract idea, and, therefore, the claim is directed to an abstract idea. Step 2B Analysis: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to the integration of the abstract idea into a practical application, the additional element(s) of: cross-entropy loss function amount(s) to no more than indicating a field of use or technological environment in which to apply the judicial exception (MPEP 2106.05(h)) additional information regarding the training do(es) not apply the exception in a meaningful way (MPEP 2106.05(e)) The additional element(s) do(es) not provide an inventive concept, and, therefore, the claim is not patent eligible. Regarding claim 4, the claim is rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Step 1 Analysis: Claim 4 is directed to a method, which is directed to a process, one of the statutory categories. Step 2A Prong One Analysis: The claim recites a(n) model compression method. The Step 2A Prong One Analysis for claim 1 is applicable here since claim 4 carries out the method of claim 1 but for the recitation of additional element(s) of wherein the simultaneously training comprises simultaneously training the internal classification layer added to each encoder layer using hyperparameter values identical to hyperparameter values previously used for fine tuning of the input model. Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. In particular, the claim recites additional information regarding the training and the element(s) do(es) not apply the exception in a meaningful way (MPEP 2106.05(e)). Accordingly, the additional element(s) do(es) not integrate the abstract idea into a practical application because the additional element(s) do(es) not impose any meaningful limits on practicing the abstract idea, and, therefore, the claim is directed to an abstract idea. Step 2B Analysis: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to the integration of the abstract idea into a practical application, the additional element(s) of additional information regarding the training do(es) not apply the exception in a meaningful way (MPEP 2106.05(e)). Not applying the exception in a meaningful way does not provide an inventive concept, and, therefore, the claim is not patent eligible. Regarding claim 5, the claim is rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Step 1 Analysis: Claim 5 is directed to a method, which is directed to a process, one of the statutory categories. Step 2A Prong One Analysis: The claim recites a(n) model compression method. The limitation of measuring performance for an output of each encoder layer to which the internal classification layer is added using verification data used for evaluation of the input model, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. If a claim limitation, under its broadest reasonable interpretation, covers performance of the limitation in the mind, then it falls within the "Mental Processes" grouping. Accordingly, the claim recites an abstract idea. Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. The claim does not recite any additional elements which integrate the abstract idea into a practical application and, therefore, does not impose any meaningful limits on practicing the abstract idea.

Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. In particular, the claim recites additional information regarding the performance drop tolerance range and the element(s) do(es) not apply the exception in a meaningful way (MPEP 2106.05(e)). Accordingly, the additional element(s) do(es) not integrate the abstract idea into a practical application because the additional element(s) do(es) not impose any meaningful limits on practicing the abstract idea, and, therefore, the claim is directed to an abstract idea. Step 2B Analysis: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to the integration of the abstract idea into a practical application, the additional element(s) of additional information regarding the performance drop tolerance range do(es) not apply the exception in a meaningful way (MPEP 2106.05(e)). Not applying the exception in a meaningful way does not provide an inventive concept, and, therefore, the claim is not patent eligible.

Step 1 Analysis: Claim 16 is directed to a computer device, which is directed to a machine, one of the statutory categories. Step 2A Prong One Analysis: The claim recites a(n) computer device. The limitation of measure performance for an output of each encoder layer to which the internal classification layer is added using verification data used for evaluation of the input model, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. If a claim limitation, under its broadest reasonable interpretation, covers performance of the limitation in the mind, then it falls within the "Mental Processes" grouping. Accordingly, the claim recites an abstract idea. Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. The claim does not recite any additional elements which integrate the abstract idea into a practical application and, therefore, does not impose any meaningful limits on practicing the abstract idea. Therefore, the claim is directed to an abstract idea. Step 2B Analysis: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to the integration of the abstract idea into a practical application, the claim does not recite any additional elements which provide an inventive concept, and, therefore, the claim is not patent eligible. Regarding claim 17, the claim is rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Step 1 Analysis: Claim 17 is directed to a computer device, which is directed to a machine, one of the statutory categories. Step 2A Prong One Analysis: The claim recites a(n) computer device. The Step 2A Prong One Analysis for claim 14 is applicable here since claim 17 carries out the computer device of claim 14 but for the recitation of additional element(s) of wherein the performance drop tolerance range is determined based on M% of performance of the input model using verification data used for evaluation of the input model, and M denotes a positive rational number. Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. In particular, the claim recites additional information regarding the performance drop tolerance range and the element(s) do(es) not apply the exception in a meaningful way (MPEP 2106.05(e)). Accordingly, the additional element(s) do(es) not integrate the abstract idea into a practical application because the additional element(s) do(es) not impose any meaningful limits on practicing the abstract idea, and, therefore, the claim is directed to an abstract idea. Step 2B Analysis: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to the integration of the abstract idea into a practical application, the additional element(s) of additional information regarding the performance drop tolerance range do(es) not apply the exception in a meaningful way (MPEP 2106.05(e)). Not applying the exception in a meaningful way does not provide an inventive concept, and, therefore, the claim is not patent eligible. Regarding claim 18, the claim is rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Step 1 Analysis: Claim 18 is directed to a computer device, which is directed to a machine, one of the statutory categories. Step 2A Prong One Analysis: The claim recites a(n) computer device. The limitation of determine a lower pruning limit of encoder layers included in the input model, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. If a claim limitation, under its broadest reasonable interpretation, covers performance of the limitation in the mind, then it falls within the "Mental Processes" grouping. Accordingly, the claim recites an abstract idea. Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. The claim does not recite any additional elements which integrate the abstract idea into a practical application and, therefore, does not impose any meaningful limits on practicing the abstract idea. Therefore, the claim is directed to an abstract idea. Step 2B Analysis: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to the integration of the abstract idea into a practical application, the claim does not recite any additional elements which provide an inventive concept, and, therefore, the claim is not patent eligible. Regarding claim 19, the claim is rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Step 1 Analysis: Claim 19 is directed to a computer device, which is directed to a machine, one of the statutory categories. Step 2A Prong One Analysis: The claim recites a(n) computer device. The limitation of perform additional pruning when a model derived by pruning the upper encoder layers of the final layer has more encoder layers than the lower pruning limit, as drafted, is a process that, under its broadest reasonable interpretation, covers a mental process. The limitation is directed to observation, evaluation, judgment and opinion and is a process capable of being performed by a human mentally or using pen and paper. If a claim limitation, under its broadest reasonable interpretation, covers performance of the limitation in the mind, then it falls within the "Mental Processes" grouping. Accordingly, the claim recites an abstract idea. Step 2A Prong Two Analysis: With respect to the abstract idea, the judicial exception is not integrated into a practical application. The claim does not recite any additional elements which integrate the abstract idea into a practical application and, therefore, does not impose any meaningful limits on practicing the abstract idea. Therefore, the claim is directed to an abstract idea. Step 2B Analysis: The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to the integration of the abstract idea into a practical application, the claim does not recite any additional elements which provide an inventive concept, and, therefore, the claim is not patent eligible.
