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 file provisions of the AIA .
This office action is in response to remarks filed 12/08/2025.
Claims 1-30 are pending and presented for examination. Claims 1, 15, 16, and 30 are amended. No claims have been cancelled, withdrawn, or added.
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 12/08/2025 has been entered.
Response to Amendment
Per the last office, filed 10/08/2025, the limitation “the plurality of first blocks is recoverable based on less than all of the plurality of the second blocks if more than a threshold number of second blocks in the plurality of second blocks are decodable”, as written, for claim 1 does not carry patentable weight. This step of recovering code blocks is performed at the second wireless device and not the first device as recited in the preamble. In addition, examiner refers applicant to the interview summary, filed 07/17/2025, which states “Discussion on Claim 1 and issue of second blocks are decodable with a threshold number so that first blocks are recoverable. Claim 1 is directed to a first wireless device that encodes and transmits the blocks but does not decode or recover blocks. Thus, the limitation does not carry patentable weight as this step is not performed in the first wireless device.” Applicant’s proposed amendments of claims 1 and 15 to this limitation do not overcome the issue.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1- 6, 9, 15-21, 24, and 30 are rejected under 35 U.S.C. 103 as being unpatentable over Yu et al. (US 20200382204-A1, hereinafter “Yu”), in view of Guo et al. (US 20230118018 A1, hereinafter “Guo”).

According to an aspect, a method comprises: generating, by a first apparatus, a transport block and error detection bits for the transport block; generating, by the first apparatus, a first number of code block groups by using the transport block and the error detection bits, wherein the first number is two or higher and based on a number of code blocks a second apparatus is able to decode in parallel processing; generating, by the first apparatus, error detection bits for at least one of the code block groups; generating, by the first apparatus, a plurality of code blocks for each code block group, and causing transmission of the plurality of code blocks to the second apparatus.

An enhanced error recovery method for ultra-reliable communication. In the proposed method, an XOR code block is additionally placed in the code block group at the transmitting side. The XOR code block is obtained by performing bit-based XOR operation on the code blocks constituting the code block group. When an error occurs in one of code blocks in the code block group, the receiving side recovers the erroneous code block by using the XOR code block and the other code blocks. Therefore, the proposed method can effectively meet the requirement of ultra-reliable and low latency communication.
