Office Action

§101
DETAILED ACTION Claims 1-20 have been examined. 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 . Examiner Interpretations Local-Global Mixing - Note that the claimed “mixing” is solely a mathematical function, as taught in Applicant's Specification: [0031] The FNO component receives an embedding tensor input and performs a mixing function to learn global perception following Fourier Transform, frequency mixing, and inverse Fourier Transform. [0040] … The global convolution kernel K may not be explicitly trained to preserve computing overhead. Instead, a frequency mixing weight W = F(K) E Chxw may be utilized and Equation (2) becomes… [0048] Equation (7) defines how tokens at different spatial locations are mixed (via the token-wise convolution) and hence addresses the token boundary inconsistency issue and long-range dependency requirements. Embedding Paths - Note that the claimed “embedding” solely is a mathematical step, as taught in Applicant's Specification: [0031] The FNO component receives an embedding tensor input and performs a mixing function to learn global perception following Fourier Transform, frequency mixing, and inverse Fourier Transform. Fourier Neural Operator - Note that the claimed “Fourier Neural Operator (FNO)” is solely a mathematical step, as taught in Applicant's Specification: [0040] A Fourier Neural Operator implements a kernel K integral at some token g:… Claim Objections Claims 2, 10, and 16 are objected to because of the following informalities: Each has the typo in an equation that recites: “…a kernel size 2□ + 1…” Note that the square box, in its broadest reasonable interpretation, is likely intended to be “(stride)” or “(s)”, as supported in the Specification regarding kernel size. Appropriate correction is required. Claims 15 is objected to because of the following informality: The last limitation recites: performing a token-wise convolutional (sic.) to implement local-global mixing of the features of the circuit mask. It is likely that the recited word “convolutional” was intended to be the word “convolution.” Appropriate correction is required. Claim Rejections - 35 U.S.C. § 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. The invention, as taught in Claims 1-20, is directed to “mental steps” and “mathematical steps” without significantly more. The claims recite: • token-shared Fourier neural operator unit (i.e., mathematical calculation) • token-wise convolution layer (i.e., mathematical calculation) • token-wise convolutional layer implements local-global mixing (i.e., mathematical calculation) Claim 1 Step 1 inquiry: Does this claim fall within a statutory category? The preamble of the claim recites “1. A neural network comprising:…” Therefore, it is a “neural network,” which is NOT a statutory category of invention. Therefore, the answer to the inquiry is: “NO.” Step 2A (Prong One) inquiry: Are there limitations in Claim 1 that recite abstract ideas? YES. The following limitations in Claim 1 recite abstract ideas that fall within at least one of the groupings of abstract ideas enumerated in the 2019 PEG. Specifically, they are “mathematical steps”: • token-shared Fourier neural operator unit (i.e., mathematical calculation) • token-wise convolution layer (i.e., mathematical calculation) • token-wise convolutional layer implements local-global mixing (i.e., mathematical calculation) Step 2A (Prong Two) inquiry: Are there additional elements or a combination of elements in the claim that 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? Applicant’s claims contain the following “additional elements”: (1) A “neural network” (2) A “unit” (3) A “layer” (4) A “circuit mask” (5) A “circuit mask generator” A “neural network” is a broad term which is described at a high level. M.P.E.P. § 2016.05(f) recites: 2106.05(f) Mere Instructions To Apply An Exception [R-10.2019] Another consideration when determining whether a claim integrates a judicial exception into a practical application in Step 2A Prong Two or recites significantly more than a judicial exception in Step 2B is whether the additional elements amount to more than a recitation of the words “apply it” (or an equivalent) or are more than mere instructions to implement an abstract idea or other exception on a computer. As explained by the Supreme Court, in order to make a claim directed to a judicial exception patent-eligible, the additional element or combination of elements must do “‘more than simply stat[e] the [judicial exception] while adding the words ‘apply it’”. Alice Corp. v. CLS Bank, 573 U.S. 208, 221, 110 USPQ2d 1976, 1982-83 (2014) (quoting Mayo Collaborative Servs. V. Prometheus Labs., Inc., 566 U.S. 66, 72, 101 USPQ2d 1961, 1965). Thus, for example, claims that amount to nothing more than an instruction to apply the abstract idea using a generic computer do not render an abstract idea eligible. Alice Corp., 573 U.S. at 223, 110 USPQ2d at 1983. See also 573 U.S. at 224, 110 USPQ2d at 1984 (warning against a § 101 analysis that turns on “the draftsman’s art”). This “neural network” limitation does not integrate the additional element into a practical application and represents “insignificant extra-solution activity”. (See, M.P.E.P. § 2106.05(I)(A)). A “unit” is a broad term which is described at a high level. M.P.E.P. § 2016.05(f) recites: 2106.05(f) Mere Instructions To Apply An Exception [R-10.2019] Another consideration when determining whether a claim integrates a judicial exception into a practical application in Step 2A Prong Two or recites significantly more than a judicial exception in Step 2B is whether the additional elements amount to more than a recitation of the words “apply it” (or an equivalent) or are more than mere instructions to implement an abstract idea or other exception on a computer. As explained by the Supreme Court, in order to make a claim directed to a judicial exception patent-eligible, the additional element or combination of elements must do “‘more than simply stat[e] the [judicial exception] while adding the words ‘apply it’”. Alice Corp. v. CLS Bank, 573 U.S. 208, 221, 110 USPQ2d 1976, 1982-83 (2014) (quoting Mayo Collaborative Servs. V. Prometheus Labs., Inc., 566 U.S. 66, 72, 101 USPQ2d 1961, 1965).

This “unit” limitation does not integrate the additional element into a practical application and represents “insignificant extra-solution activity”. (See, M.P.E.P. § 2106.05(I)(A)). A “layer” is a broad term which is described at a high level.

This “layer” limitation does not integrate the additional element into a practical application and represents “insignificant extra-solution activity”. (See, M.P.E.P. § 2106.05(I)(A)). A “circuit mask” is a broad term which is described at a high level. M.P.E.P. § 2016.05(f) recites: 2106.05(f) Mere Instructions To Apply An Exception [R-10.2019] Another consideration when determining whether a claim integrates a judicial exception into a practical application in Step 2A Prong Two or recites significantly more than a judicial exception in Step 2B is whether the additional elements amount to more than a recitation of the words “apply it” (or an equivalent) or are more than mere instructions to implement an abstract idea or other exception on a computer.

This “circuit mask” limitation does not integrate the additional element into a practical application and represents “insignificant extra-solution activity”. (See, M.P.E.P. § 2106.05(I)(A)). A “circuit mask generator” is a broad term which is described at a high level.

This “circuit mask generator” limitation does not integrate the additional element into a practical application and represents “insignificant extra-solution activity”. (See, M.P.E.P. § 2106.05(I)(A)). The answer to the inquiry is “NO”, no additional elements integrate the claimed abstract idea into a practical application. Step 2B inquiry: Does the claim provide an inventive concept, i.e., does the claim recite additional element(s) or a combination of elements that amount to significantly more than the judicial exception in the claim? Applicant’s claims contain the following “additional elements”: (1) A “neural network” (2) A “unit” (3) A “layer” (4) A “circuit mask” (5) A “circuit mask generator” A “neural network” is a broad term which is described at a high level.

Therefore, the claim as a whole does not amount to significantly more than the exception itself (i.e., there is no inventive concept in the claim). (See, M.P.E.P. § 2106.05(II)). A “unit” is a broad term which is described at a high level.

Therefore, the claim as a whole does not amount to significantly more than the exception itself (i.e., there is no inventive concept in the claim). (See, M.P.E.P. § 2106.05(II)). Therefore, the answer to the inquiry is “NO”, no additional elements provide an inventive concept that is significantly more than the claimed abstract ideas the claimed abstract idea into a practical application. Claim 1 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 2 Claim 2 recites: 2. The neural network of claim 1, the token-wise convolutional layer comprising a kernel size 2□ + 1, where s is a stride size of the convolution. Regarding Step 1 inquiry, independent Clam 1 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 2 merely teaches an equation (i.e., a mathematical step). It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 2 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 3 Claim 3 recites: 3. The neural network of claim 2, comprising a plurality of embedding paths. Regarding Step 1 inquiry, independent Clam 1 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 3 merely teaches mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 3 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 4 Claim 4 recites: 4. The neural network of claim 3, wherein the embedding paths are configured with a variety of different token sizes. Regarding Step 1 inquiry, independent Clam 1 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 4 merely teaches mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 4 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 5 Claim 5 recites: 5. The neural network of claim 3, wherein a number of the embedding paths is four. Regarding Step 1 inquiry, independent Clam 1 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 5 merely teaches mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 5 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 6 Claim 6 recites: 6. The neural network of claim 5, wherein three of the four embedding paths comprise token sizes different from one another. Regarding Step 1 inquiry, independent Clam 1 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 6 merely teaches mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 6 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 7 Claim 7 recites: 7. The neural network of claim 1, wherein one of the embedding paths comprises a token size of one to compensate for boundary conditions in the circuit mask. Regarding Step 1 inquiry, independent Clam 1 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 7 merely teaches mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 7 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 8 Claim 8 recites: 8. The neural network of claim 1, further comprising a concatenator disposed to receive outputs of the embedding paths. Regarding Step 1 inquiry, independent Clam 1 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 8 merely teaches the mental step of concatenation. Applicant's Specification recites: [0053] Each shared FNO, by its structural nature, truncates high frequency coefficients to focus the CFNO-based mask optimizer network500 on global information acquisition. These high frequency components are however important is mask learning, because pixel-level changes on masks will result in magnified changes to wafer images. The convolution path may therefore be designed to compensate for high frequency information loss. Once the token embedding from the four learning paths is established, an aggregation (e.g., concatenation operation508) is performed to gather learned information. This is followed in the example embodiment by a series of convolution layers504 and transposed convolution layers510 to generate masks. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 8 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 9 Step 1 inquiry: Does this claim fall within a statutory category? The preamble of the claim recites “9. A circuit mask generator comprising:…” Therefore, it is a “circuit mask generator,” which is NOT a statutory category of invention. Therefore, the answer to the inquiry is: “NO.” Step 2A (Prong One) inquiry: Are there limitations in Claim 9 that recite abstract ideas? YES. The following limitations in Claim 9 recite abstract ideas that fall within at least one of the groupings of abstract ideas enumerated in the 2019 PEG. Specifically, they are “mathematical steps”: • token-shared Fourier neural operator (FNO) unit (i.e., mathematical calculation) • plurality of distinct embedding paths (i.e., mathematical calculation) • embedding paths configured to each input a same tensor (i.e., mathematical calculation) • apply a plurality of different token sizes to an embedding (i.e., mathematical calculation) • token-wise convolution layer (i.e., mathematical calculation) • local-global mixing of the features (i.e., mathematical calculation) Step 2A (Prong Two) inquiry: Are there additional elements or a combination of elements in the claim that 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? Applicant’s claims contain the following “additional elements”: (1) A “neural network” (2) A “unit” (3) A “layer” (4) A “circuit mask” (5) A “circuit mask generator” A “neural network” is a broad term which is described at a high level.

Therefore, the answer to the inquiry is “NO”, no additional elements provide an inventive concept that is significantly more than the claimed abstract ideas the claimed abstract idea into a practical application. Claim 9 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 10 Claim 10 recites: 10. The circuit mask generator of claim 9, the token-wise convolution layer comprising a kernel size 2□ + 1, where s is a convolution stride size. Regarding Step 1 inquiry, independent Clam 9 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 10 merely teaches an equation (i.e., a mathematical step). It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 10 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 11 Claim 11 recites: 11. The circuit mask generator of claim 9, wherein the FNO unit comprises four embedding paths. Regarding Step 1 inquiry, independent Clam 9 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 11 merely mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 11 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 12 Claim 12 recites: 12. The circuit mask generator of claim 11, wherein three of the four embedding paths comprise token sizes different from one another. Regarding Step 1 inquiry, independent Clam 9 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 12 mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 12 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 13 Claim 13 recites: 13. The circuit mask generator of claim 9, wherein one of the embedding paths comprises a token size of one. Regarding Step 1 inquiry, independent Clam 9 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 13 merely teaches mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 13 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 14 Claim 14 recites: 14. The circuit mask generator of claim 9, further comprising logic disposed to receive and concatenate outputs of the embedding paths. Regarding Step 1 inquiry, independent Clam 9 fails the Step 1 inquiry, as noted above, covers software per se, and is incorporated by reference to this claim. Therefore, this claim fails 35 U.S.C. § 101 on that basis. Further, Applicant’s Claim 14 merely teaches the mental step of concatenation. Applicant's Specification recites: [0053] Each shared FNO, by its structural nature, truncates high frequency coefficients to focus the CFNO-based mask optimizer network500 on global information acquisition. These high frequency components are however important is mask learning, because pixel-level changes on masks will result in magnified changes to wafer images. The convolution path may therefore be designed to compensate for high frequency information loss. Once the token embedding from the four learning paths is established, an aggregation (e.g., concatenation operation508) is performed to gather learned information. This is followed in the example embodiment by a series of convolution layers504 and transposed convolution layers510 to generate masks. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 14 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 15 Step 1 inquiry: Does this claim fall within a statutory category? The preamble of the claim recites “15. A process for improving a circuit mask, the process comprising:…” Therefore, it is a “process,” (or, a “method”) which is a statutory category of invention. Therefore, the answer to the inquiry is: “YES.” Step 2A (Prong One) inquiry: Are there limitations in Claim 15 that recite abstract ideas? YES. The following limitations in Claim 15 recite abstract ideas that fall within at least one of the groupings of abstract ideas enumerated in the 2019 PEG. Specifically, they are “mathematical steps”: • applying features of the circuit mask to a token-shared Fourier neural operator (FNO) unit comprising a plurality of distinct embedding paths (i.e., mathematical calculation) • embedding paths process the features with different token sizes (i.e., mathematical calculation) • performing a token-wise convolutional (sic.) to implement local-global mixing of the features (i.e., mathematical calculation) Step 2A (Prong Two) inquiry: Are there additional elements or a combination of elements in the claim that 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? Applicant’s claims contain the following “additional elements”: (1) A “neural network” (2) A “unit” (3) A “layer” (4) A “circuit mask” (5) A “circuit mask generator” A “neural network” is a broad term which is described at a high level.

Alice Corp., 573 U.S. at 223, 110 USPQ2d at 1983. See also 573 U.S. at 224, 110 USPQ2d at 1984 (warning against a § 101 analysis that turns on “the draftsman’s art”). This “layer” limitation does not integrate the additional element into a practical application and represents “insignificant extra-solution activity”. (See, M.P.E.P. § 2106.05(I)(A)). A “circuit mask” is a broad term which is described at a high level. M.P.E.P. § 2016.05(f) recites: 2106.05(f) Mere Instructions To Apply An Exception [R-10.2019] Another consideration when determining whether a claim integrates a judicial exception into a practical application in Step 2A Prong Two or recites significantly more than a judicial exception in Step 2B is whether the additional elements amount to more than a recitation of the words “apply it” (or an equivalent) or are more than mere instructions to implement an abstract idea or other exception on a computer. As explained by the Supreme Court, in order to make a claim directed to a judicial exception patent-eligible, the additional element or combination of elements must do “‘more than simply stat[e] the [judicial exception] while adding the words ‘apply it’”. Alice Corp. v. CLS Bank, 573 U.S. 208, 221, 110 USPQ2d 1976, 1982-83 (2014) (quoting Mayo Collaborative Servs. V. Prometheus Labs., Inc., 566 U.S. 66, 72, 101 USPQ2d 1961, 1965).

This “circuit mask” limitation does not integrate the additional element into a practical application and represents “insignificant extra-solution activity”. (See, M.P.E.P. § 2106.05(I)(A)). A “circuit mask generator” is a broad term which is described at a high level. M.P.E.P. § 2016.05(f) recites: 2106.05(f) Mere Instructions To Apply An Exception [R-10.2019] Another consideration when determining whether a claim integrates a judicial exception into a practical application in Step 2A Prong Two or recites significantly more than a judicial exception in Step 2B is whether the additional elements amount to more than a recitation of the words “apply it” (or an equivalent) or are more than mere instructions to implement an abstract idea or other exception on a computer.

This “circuit mask generator” limitation does not integrate the additional element into a practical application and represents “insignificant extra-solution activity”. (See, M.P.E.P. § 2106.05(I)(A)). The answer to the inquiry is “NO”, no additional elements integrate the claimed abstract idea into a practical application. Step 2B inquiry: Does the claim provide an inventive concept, i.e., does the claim recite additional element(s) or a combination of elements that amount to significantly more than the judicial exception in the claim? Applicant’s claims contain the following “additional elements”: (1) A “neural network” (2) A “unit” (3) A “layer” (4) A “circuit mask” (5) A “circuit mask generator” A “neural network” is a broad term which is described at a high level.

Therefore, the claim as a whole does not amount to significantly more than the exception itself (i.e., there is no inventive concept in the claim). (See, M.P.E.P. § 2106.05(II)). Therefore, the answer to the inquiry is “NO”, no additional elements provide an inventive concept that is significantly more than the claimed abstract ideas the claimed abstract idea into a practical application. Claim 15 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 16 Claim 16 recites: 16. The process of claim 15, where the token-wise convolution operates with a kernel size 2□ + 1, where s is a convolution stride size. Applicant’s Claim 16 merely teaches an equation (i.e., a mathematical step). It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 16 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 17 Claim 17 recites: 17. The process of claim 15, wherein the FNO unit comprises four embedding paths. Applicant’s Claim 17 merely mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 17 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 18 Claim 18 recites: 18. The process of claim 17, wherein at least three of the four embedding paths comprise token sizes different from one another. Applicant’s Claim 18 merely mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 18 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 19 Claim 19 recites: 19. The process of claim 15, wherein one of the embedding paths comprises a token size of one. Applicant’s Claim 19 merely teaches mathematical embedding steps discussed in the Examiner's Interpretations, above. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 19 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Claim 20 Claim 20 recites: 20. The process of claim 15, further comprising: concatenating outputs of the embedding paths. Applicant’s Claim 20 merely teaches the mental step of concatenation. Applicant's Specification recites: [0053] Each shared FNO, by its structural nature, truncates high frequency coefficients to focus the CFNO-based mask optimizer network500 on global information acquisition. These high frequency components are however important is mask learning, because pixel-level changes on masks will result in magnified changes to wafer images. The convolution path may therefore be designed to compensate for high frequency information loss. Once the token embedding from the four learning paths is established, an aggregation (e.g., concatenation operation508) is performed to gather learned information. This is followed in the example embodiment by a series of convolution layers504 and transposed convolution layers510 to generate masks. It does not integrate the abstract idea to a practical application, nor is it anything significantly more than the abstract idea. (See, 2106.05(a)(II).) Claim 20 is, therefore, NOT ELIGIBLE subject matter under 35 U.S.C. § 101. Relevant art Claims 1-19 are not rejected under art since when reading the claims in light of the specification, as per MPEP § 2111.01, none of the references of record, whether taken alone or in combination, discloses or suggests the combination of limitations specified in independent Claim 1. Specifically, the closest art of Rao, et al., Global Filter Networks for Image Classification, arXiv:2107.00645v2 [cs.CV] 26 Oct 2021, 26 OCT 2021, pp. 1-19 fails to expressly teach: Claim 1 s "...token-wise convolution layer..." Further, none of the references of record, whether taken alone or in combination, discloses or suggests the combination of limitations specified in independent Claim 9.
