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 5-9 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph.
Claims 5, 6, and 9 recite “modulator driving signals”. There is insufficient antecedent basis for this limitation in the claims. Examiner notes that the phrase “modulator driving signals” appears in claim 4. For prior art mapping purposes, claims 5, 6, and 9 are interpreted as depending on claim 4.
Claims 7 and 8 recite a “coupling network”. There is insufficient antecedent basis for this limitation in the claims. Examiner notes that the phrase “coupling network” appears in claim 4. For prior art mapping purposes, claims 7 and 8 are interpreted as depending on claim 4.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1-19 are rejected under 35 U.S.C. 103 as being unpatentable over Oshima et al (Pub. No.: US 20220101099 A1), hereafter Oshima in view of Nakajima et al (Pub. No.: US 20210026220 A1), hereafter Nakajima.
Regarding claim 1, Oshima teaches receiving an input symbol (Sensor 200 receives input, P0046); applying a time mask to the input symbol to produce a plurality of time multiplexed time nodes (Time division multiplexing is performed on input data, P0135); modulating, using the plurality of time nodes, a plurality of frequency channels to produce a plurality of frequency nodes (Server 104 may perform spectrum sensing on a frequency region using frequency channels and time-division broadcasts in order to produce frequency bands, P0094-P0095); multiplexing the plurality of frequency nodes to produce a plurality of multiplexed frequency nodes (Frequency division multiplexing and code division multiplexing results in multiplexed transmission and reception by child devices, P0097-P0098); coupling the multiplexed frequency nodes into a reservoir (Frequency-division multiplexing is performed on reservoir 102, P0121, P0135), … receiving a delayed plurality of multiplexed frequency nodes from the reservoir (Data is transmitted from child devices after multiplexing, P0099); demultiplexing the delayed plurality of multiplexed frequency nodes to produce a plurality of delayed time nodes (Time-division broadcasts are used to divide and transmit data using frequency channels, P0094. Low frequency and high frequency components from transmitted data are separated, P0099); modulating, using the plurality of delayed time nodes and the input time nodes, the plurality of frequency channels (Server 104 instructs the frequency channels using frequency bands based on analysis of time series data, P0094, P0067-P0070); and outputting a response, the response based on the plurality of delayed time nodes (Server 104 may collect time-series data and analyze time series data using deep neural network 101 before outputting the solution, feature amount, or feature data through output unit 300, P0067-P0070).
Oshima does not appear to explicitly teach “the reservoir including a non- linear element”.
Nakajima teaches the reservoir including a non-linear element (Reservoir computing network includes a non-linear element, P0008).
Accordingly, it would have been obvious to a person having ordinary skill in the
art before the effective filing date of the claimed invention, having the teachings of
Oshima and before them, to include Nakajima’s specific teaching of a reservoir computing network including a non-linear element in Oshima’s system of information processing. One would have been motivated to make such a combination of implementing a reservoir computing network with a nonlinear element and optical delay line (see Nakajima P0008) and using reservoir computing to perform tasks for time-series signals (see Oshima P0060, P0063).
Regarding claim 10, Oshima teaches a frequency multiplexer portion receiving a plurality of virtual nodes of an input symbol (Sensor 200 receives input, P0046), the frequency multiplexer portion outputting a modulated wavelength division multiplexing signal include the plurality of virtual nodes (Server 104 may perform spectrum sensing on a frequency region using frequency channels and time-division broadcasts in order to produce frequency bands, P0094-P0095), the plurality of virtual nodes including a plurality of time nodes and a plurality of frequency nodes (Time division multiplexing is performed on input data, P0135);… a delay line coupled to the frequency multiplexer portion and the modulator portion, the delay line receiving the plurality of modulated frequency nodes and producing a plurality of delayed frequency nodes (Data is transmitted from child devices after multiplexing, P0099); a demultiplexer portion receiving the plurality of delayed frequency nodes and producing a plurality of coupling matrix inputs, each of the plurality of inputs being derived from a demultiplexed one of the plurality of delayed frequency nodes (Time-division broadcasts are used to divide and transmit data using frequency channels, P0094. Low frequency and high frequency components from transmitted data are separated, P0099).
Oshima does not appear to explicitly teach “a modulator portion coupled to the frequency multiplexer portion for modulating the plurality of virtual nodes to produce a plurality of modulated frequency nodes… and a coupling network coupled to the demultiplexer portion and the modulator portion, the coupling network receiving the coupling matrix inputs and producing a plurality of modulator driving signals”.
Nakajima teaches a modulator portion coupled to the frequency multiplexer portion for modulating the plurality of virtual nodes to produce a plurality of modulated frequency nodes (optical multiplexing is used with optical modulation for modulating multiplexed signals, P0015);…and a coupling network coupled to the demultiplexer portion and the modulator portion, the coupling network receiving the coupling matrix inputs and producing a plurality of modulator driving signals (A neural network may take inputs of a coupling matrix for the purpose of modulating reservoir computing circuit with an optical modulator, P0043, P0048, P0056. NN for reservoir computing may include demodulating signals, P0031).
Accordingly, it would have been obvious to a person having ordinary skill in the
art before the effective filing date of the claimed invention, having the teachings of
Oshima and before them, to include Nakajima’s specific teachings of an optical multiplexing and optical modulation in Oshima’s system of information processing. One would have been motivated to make such a combination of implementing optical multiplexing and optical modulation in a time domain in a reservoir computing network (see Nakajima P0015) and using reservoir computing to perform tasks for time-series signals (see Oshima P0060, P0063).
Regarding claims 2 and 11, Oshima in view of Nakajima teaches the limitations of claim 1 and 10 as outlined above. Oshima further teaches wherein the plurality of frequency channels are modulated after being multiplexed to form the plurality of multiplexed frequency nodes (Frequency bands may be produced by performing spectrum sensing using frequency channels after code division multiplexing, P0094-P0095, P0097).
Regarding claim 3 and 12, Oshima in view of Nakajima teaches the limitations of claim 1 and 10 as outlined above. Oshima further teaches wherein the plurality of frequency channels are modulated before being multiplexed to form the plurality of multiplexed frequency nodes (Frequency bands may be produced by performing spectrum sensing using frequency channels before frequency division multiplexing, P0094-P0095, P0098).
Regarding claim 4, Oshima in view of Nakajima teaches the elements of claim 1 as outlined above. Nakajima further teaches wherein the plurality of delayed time nodes are input to a coupling network, the coupling network outputting a plurality of modulator driving signals (neural network may take inputs of a coupling matrix for the purpose of modulating a reservoir computing circuit with an optical modulator, P0043, P0048, P0056).
Regarding claims 5 and 13, Oshima in view of Nakajima teaches the elements of claims 4 and 10 as outlined above. Nakajima further teaches wherein the plurality of modulator driving signals are outputs of electronic circuits (Signals may be output from electric signal processing circuit 210, P0030).

Regarding claim 7 and 15, Oshima in view of Nakajima teaches the elements of claims 4 and 10 as outlined above. Nakajima further teaches a modulator profile compensator to receive the plurality of delayed time nodes, the output of the modulator profile compensator being provided as inputs to the coupling network (Electrical processing circuit 220 may receive time-step data as input and provide output, the result of formula 2, to reservoir computing network as input, P0041, P0005-P0006).
Regarding claim 8 and 16, Oshima in view of Nakajima teaches the elements of claims 4 and 10 as outlined above. Nakajima further teaches wherein a demultiplexing module and the coupling network are combined in an optical circuit (Optical circulation circuit may include both optical coupler 218 and coherent optical receiver 219 used to demodulate signals, P0031).
Regarding claim 9, Oshima in view of Nakajima teaches the elements of claim 4 as outlined above. Nakajima further teaches wherein the plurality of modulator driving signals are based on the plurality of delayed time nodes and a masked data input, the masked data input being an input to the coupling network (Modulated signals are based on a mask function and a time series signal, the output of the mask function being input to the reservoir computing network, P0056).
Regarding claim 19, Oshima in view of Nakajima teaches the elements of claim 10 as outlined above. Nakajima further teaches wherein the coupling network further receives a masked data input, the plurality of modulator driving signals being based on both the coupling matrix inputs and the masked data input (Reservoir computing network may receive the output of a mask function with modulated signals being based on a coupling matrix and the mask function output, P0056).
