Office Action

§102 §103
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 § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1, 3, 5, 8-9, 11, 13, 18-19 and 29-30 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lei et al (US 2022/0294573). Hereinafter referred to as lei. Regarding claims 1, 18 and 29-30, Lei discloses an apparatus for wireless communication at a user equipment (UE) (see at least figure 1), comprising: memory; and at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor, individually or in any combination, (see at least figure 1) is configured to receive one or more downlink transmissions from a network node; and transmit two-part hybrid automatic repeat request (HARQ) acknowledgement (HARQ-ACK) feedback for the one or more downlink transmissions based (see at least figure 7) on at least one of a first compression data set for a first codebook and a second compression data set for a second HARQ-ACK codebook (see at least paragraph [0045]), or a third compression data set based on a combination of the first HARQ-ACK codebook and the second HARQ-ACK codebook (see at least paragraphs [0004], [0045], [0094]). Regarding claim 3. Lei discloses an apparatus wherein the two-part HARQ-ACK feedback includes jointly compressed feedback based on the third compression data set (see at least paragraphs [0004], [0045], [0094]). Regarding claim 5, Lei discloses an apparatus wherein the at least one processor, individually or in any combination, is further configured to receive, from the network node, a first configuration indicative of at least one of the first compression data set, the second compression data set, or the third compression data set (see at least paragraph [0099]). Regarding claim 8, Lei discloses an apparatus wherein the two-part HARQ-ACK feedback includes separate compressions of first HARQ-ACK feedback based on the first compression data set and the first HARQ-ACK codebook and second HARQ-ACK feedback based on the second compression data set and the second HARQ-ACK codebook (see at least figures 7-8 and paragraphs [0004], [0045], [0094]). Regarding claim 9. Lei discloses an apparatus wherein the at least one processor, individually or in any combination, is further configured to encode, as a payload for the two-part HARQ-ACK feedback and for an associated channel, at least one of a first part of a first compressed codebook, the first part of a second compressed codebook, a second part of the first compressed codebook, or the second part of the second compressed codebook (see at least figures 7-8). Regarding claim 11. Lei discloses an apparatus wherein to encode, the at least one processor, individually or in any combination, is configured to separately encode each of the first part of the first compressed codebook, the first part of the second compressed codebook, the second part of the first compressed codebook, and the second part of the second compressed codebook (see at least figures 7-8 and paragraphs [0004], [0045], [0094]). Regarding claim 13. Lei discloses an apparatus wherein the two-part HARQ-ACK feedback comprises a joint compression associated with the third compression data set that partitions the combination of the first HARQ-ACK codebook and the second HARQ-ACK codebook (see at least paragraph [0004], [0045], [0094]). Regarding claim 19, lei discloses an, apparatus wherein the at least one processor, individually or in any combination, is further configured to: decode a payload of the two-part HARQ-ACK feedback based on the first configuration (see at least paragraph [0004], [0045], [0094] and figure 1). Claim Rejections - 35 USC § 103 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. 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. Claims 17 and 28 are rejected under 35 U.S.C. 103 as being unpatentable over Lei in view of Lei et al (US 2021/0266105, hereinafter referred to as Lei-105). Regarding claims 17 and 28, Lei discloses all the limitations of the claimed invention with the exception the first compression data set is associated with transport block (TB) based feedback, and the second compression data set is associated with code block group (CBG) based feedback; or wherein the first compression data set is associated with a higher priority HARQ-ACK feedback, and the second compression data set is associated with a lower priority HARQ-ACK feedback. However, Lei-105, from the same field of endeavor, teaches the first compression data set is associated with transport block (TB) based feedback, and the second compression data set is associated with code block group (CBG) based feedback; or wherein the first compression data set is associated with a higher priority HARQ-ACK feedback, and the second compression data set is associated with a lower priority HARQ-ACK feedback (see at least abstract, and paragraphs [0004], [0029], [0032]-[0034] and [0093]). Thus, it would have been obvious to a person of ordinary skill in the art before the time of the invention to employ the teaching of Lei-105, as indicated, into the communication method of Lei for the purpose of improving transmission/retransmission resources utilization. Allowable Subject Matter Claims 2, 4, 6-7, 10, 12, 14-16, and 20-27 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See PTO_892. In the case of amending the claimed invention, Applicant is respectfully requested to indicate the portion(s) of the specification which dictate(s) the structure relied on for proper interpretation and also to verify and ascertain the metes and bounds of the claimed invention. When responding to this office action, applicants are advised to clearly point out the patentable novelty which they think the claims present in view of the state of the art disclosed by the references cited or the objections made. Applicants must also show how the amendments avoid such references or objections. See 37C.F.R 1.111(c). In addition, applicants are advised to provide the examiner with the line numbers and pages numbers in the application and/or references cited to assist examiner in locating the appropriate paragraphs.
