Office Action

§DP
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 Status This office action is in response to the communication(s) filed on 10/04/2024. Claim(s) 1-20 is/are currently presenting for examination. Claim(s) 1, 8, and 17 is/are independent claim(s). Claim(s) 1-20 is/are rejected. This action has been made NON-FINAL. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claim(s) 1-20 is/are rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claim(s) 1-20 of U.S. Patent No. 12,143,306 (hereinafter referred to as Patent '06).

Regarding claim 12, Patent '61 discloses the radio access network of claim 11, wherein the threshold value is determined based on a current time, a current location of the radio access network, or a current traffic level (Patent ’06, claim 12). Regarding claim 13, Patent '61 discloses the radio access network of claim 8, wherein the adjusting the priority of the data flow further comprises: in a scheduler of the radio access network, assigning the data flow to the Quality of Service class having a predetermined Quality of Service Class Identifier (QCI) priority, wherein the communicating the data comprises communicating the data according to the predetermined QCI priority (Patent ’06, claim 14).

Allowable Subject Matter Claims 1-20 would be allowable if the nonstatutory double patenting rejection to these claims set forth in this Office action is overcome and to include all of the limitations of the base claim and any intervening claims. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Prior art US_11240157_B1_Callaghan discloses a host device receives a first packet for a data flow; applies a first quality of service (QoS) classification to the first packet based on a first amount of data transmitted in the data flow; prioritizes transmission of the first packet to a receiver based on the first QoS classification; receives a second packet for the data flow; apply a second QoS classification to the v second packet based on a second amount of data transmitted in the data flow; prioritizes transmission of the second packet based on the second QoS classification (Callaghan figures 1, 2A, 2B, 4, and column 17 lines 26-45, and column 18 lines 28-52). Prior art US_20190379612_A1_Tiwary discloses a system assigns first priority to first traffic flow, associated with first customer, using regression technique based on first response time of first, query associated with first traffic flow; assigns second priority to second traffic flow, associated with second customer, using the regression technique based on second response time of second query associated with second traffic flow; dynamically allocates network resources to the first and second traffic flows based on the first and second priorities (Tiwary figure 13). Prior art US_11088964_B1_Smaldone discloses Systems and methods for scheduling multiple flows in a computing system or for allocating resources to the flows in the computing system. Each flow may be associated with a target priority and a target performance. A current priority can be determined for each flow and resources are allocated based on the highest current priority. Over time, the current priorities change and each flow will receive resources as the flows are scheduled for execution. No flow is starved of resources (Smaldone figure 4, and column 5 line 59 – column 6 line 28). Prior art US_9985898_B2_Ramaiah discloses store flow information, determine link characteristics, determine TCP characteristics, assign flow priority, determine link congestion, and modify congestion window size (Ramaiah figure 5).
