Office Action

§103
DETAILED ACTION 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 § 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 1-4, 7-11, 14-15 are rejected under 35 U.S.C. 103 as being unpatentable over Baldemair et al. (Baldemair) US 2023/0155731 in view of Rosenblum et al. (Rosenblum) US 2020/0334104 In regard to claim 1, Baldemair disclose A method performed by a first node in a communication system, the method comprising: ([0005]-[0009] communication between transmitting and receiving nodes in a communication system) transmitting one or more synchronization signals to a second node; ([0040]-[0050] transmit the synchronization signaling to the receiving node from the transmitting node) transmitting system information to the second node; ([0005]-[0009] [0040]-[0050] transmit control information to the receiving node from the transmitting node) transmitting, to the second node, a request message of information of the second node for an error correction; ([0032]-[0036] [0052][0079]-[0082] transmit a request of information to the receiving node from the transmitting node, such as control information or schedule information, measurement information, etc.) receiving, from the second node, a report message; ([0040]-[0045] [0077]-[0082] [0096] receive from the receiving node, a response message with the required measurement information) transmitting, to the second node, an error correction configuration message including the type of the error correction and information of the resource; ([0024]-[0026] [0032]-[0036] transmitting, to the receiving node, the error correction message including the type (error detection coding, CRC or FEC, etc. and the information of the resource) and receiving an error correction confirmation message from the second node.

In regard to claims 9-11, 14, claims 9-11, 14 are method claims corresponding to the method claims 2-4, 7 above and, therefore, are rejected for the same reasons set forth in the rejections of claims 2-4, 7. In regard to claim 15, claim 15 is a first node claim corresponding to the method claim 1 above and, therefore, is rejected for the same reasons set forth in the rejections of claim 1. Allowable Subject Matter Claim 5-6, 12-13 are objected to as being dependent upon a rejected base claim 1 and 8, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Lucarelli (US 2020/0119748) disclose A quantum computing system and associated methods. An exemplary method includes generating a specification from a binary matrix and at least one quantum check operator. The binary matrix is based at least in part on a classical error correcting code and the quantum check operator(s) is/are based on at least one multiple-qubit Pauli operator. The specification indicates which ancilla qubits are to be coupled to which data qubits. The data qubits are prepared as a plurality of multiple-qubit entangled states. The exemplary method also includes directing quantum hardware components of the quantum computing system to couple each of selected ones of the data qubits to one or more of the ancilla qubits in accordance with the couplings indicated in the specification. Each of the plurality of multiple-qubit entangled states is coupled to a plurality of the ancilla qubits…. See abstract. But Lucarelli fail to explicitly disclosed claims 5 and 12 of “wherein determining the type of the error correction to be performed and the necessary resource for the error correction further comprises: based on the bit-phase flip error rate being greater than or equal to a critical bit-phase flip error rate, determining the type of the error correction as a bit-phase flip error and determining a resource for the bit-phase flip error correction; based on the bit-phase flip error rate being less than the critical bit-phase flip error rate, and the bit flip error rate being greater than or equal to a critical bit flip error rate, determining the type of the error correction as a bit flip error and determining a resource for the bit flip error correction; and based on the bit flip error rate being less than the critical bit flip error rate, and the phase flip error rate being greater than or equal to a critical phase flip error rate, determining the type of the error correction as a phase flip error and determining a resource for the phase flip error correction.” ([0042]-[0050], etc.) Putterman et al.

See abstract. (col. 30, line 7-col. 31, line 18, etc.) But Putterman et al. fail to explicitly disclosed claim 5 and 12 of “wherein determining the type of the error correction to be performed and the necessary resource for the error correction further comprises: based on the bit-phase flip error rate being greater than or equal to a critical bit-phase flip error rate, determining the type of the error correction as a bit-phase flip error and determining a resource for the bit-phase flip error correction; based on the bit-phase flip error rate being less than the critical bit-phase flip error rate, and the bit flip error rate being greater than or equal to a critical bit flip error rate, determining the type of the error correction as a bit flip error and determining a resource for the bit flip error correction; and based on the bit flip error rate being less than the critical bit flip error rate, and the phase flip error rate being greater than or equal to a critical phase flip error rate, determining the type of the error correction as a phase flip error and determining a resource for the phase flip error correction.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to XUYANG XIA whose telephone number is (571)270-3045.
