Claim Rejections - 35 USC § 103 1. 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 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. 2. 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. 3. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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. 4. 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. Claim(s) 5, 8, 14, 16, 18-19 is/are rejected under 35 U.S.C. 103 as being unpatentable over US LIU in view of US PG Pub US 20250344252 A1 to Lutchoomun et al (hereinafter Lutchoomun). As per claim 5, LIU teaches the first node according to claim 1, Lutchoomun teaches characterized in that the first candidate signal carries a first identifier, and whether the first identifier is used to determine a position of the target priority group among the multiple candidate priority groups is related to whether the first candidate time-domain resource block belongs to the first time-domain resource group ((para 0077] , candidate device are selected and based on the position from the device determines the a position of the target priority group among the multiple candidate priority groups is related to whether the first candidate time-domain resource block belongs to the first time-domain resource group). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date, to modify the combination system of LIU by first candidate signal carries a first identifier, and whether the first identifier is used to determine a position of the target priority group among the multiple candidate priority groups is related to whether the first candidate time-domain resource block belongs to the first time-domain resource group as suggested by Lutchoomun, this modification would benefit LIU for reducing delay associated with data transmission in a mobile communication network. As per claim 8, LIU teaches the first node according to claim 1, Lutchoomun teaches characterized in that the first candidate signal carries a first identifier and first information, the first information indicating whether the transmitter of the first candidate signal is in coverage ((((para 0077] , carries a first identifier and first information, the first information indicating whether the transmitter of the first candidate signal is in coverage); at least one of the first identifier or the first information is used together with whether the first candidate time-domain resource block belongs to the first time-domain resource group to determine a position of the target priority group among the multiple candidate priority groups (((para 0077] , based on the information available used together with whether the first candidate time-domain resource block belongs to the first time-domain resource group to determine a position of the target priority group among the multiple candidate priority groups). Examiner supplies the same rationale as supplied in claim 5. As per claim 14, LIU teaches the second node according to claim 13, Lutchoomun teaches characterized in that the second node belongs to a target priority group, the target priority group being one of multiple candidate priority groups (para 0077],nodes which are belongs to a target priority group, the target priority group being one of multiple candidate priority groups ).; a position of the target priority group among the multiple candidate priority groups is related to whether the first candidate time-domain resource block belongs to the first time-domain resource group (para 0077], nodes which are belongs to a target priority group, related to whether the first candidate time-domain resource block belongs to the first time-domain resource group). Examiner supplies the same rationale as supplied in claim 5. As per claim 16, LIU teaches the second node according to claim 13, Lutchoomun teaches characterized in that the first candidate signal carries a first identifier, and whether the first identifier is used to determine the position of the target priority group among the multiple candidate priority groups is related to whether the first candidate time-domain resource block belongs to the first time-domain resource group (para 0077], identifier is used to determines position of the target priority group among the multiple candidate priority groups is related to whether the first candidate time-domain resource block belongs to the first time-domain resource group as the candidate identifier). Examiner supplies the same rationale as supplied in claim 5. As per claim 18, LIU teaches the second node according to claim 13, Lutchoomun teaches characterized in that the first candidate signal carries a first identifier and first information, the first information indicating whether the second node is in coverage ((para 0077], candidate signal carries a first identifier and first information, the first information indicating whether the second node is in coverage); the position of the target priority group among the multiple candidate priority groups is related to at least one of the first identifier or the first information and whether the first candidate time-domain resource block belongs to the first time-domain resource group (para 0077], position of the target priority group among the multiple candidate priority groups is related to at least one of the first identifier or the first information and whether the first candidate time-domain resource block belongs to the first time-domain resource group). Examiner supplies the same rationale as supplied in claim 5. As per claim 19, LIU teaches the second node according to claim 13, Lutchoomun teaches characterized in that a first priority order is indicated by second configuration information, and the first priority order is used to determine the order of the multiple candidate priority groups (((para 0077], priority order is used by the configuration to determine the order of the multiple candidate priority groups) . Examiner supplies the same rationale as supplied in claim 5. Allowable Subject Matter Claim 3-4, 6-7, 12, 15,17 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.
