Therefore, the controller can instruct (force) mobile device 602 to roam to the access point at AP cell #12 526. ¶ [0086], FIG. 18 illustrates the network of FIG. 16 after a forced roam (active grouping) of mobile device 602. Because mobile device 602 is now associated with AP cell #12 526, the access points in AP cell #3 506 and AP cell #4 508 can be switched to power save mode because they are no longer adjacent to a cell with an associated mobile device. ¶ [0087]- ¶ [0092], ¶ [0099]).
Regarding claims 2 and 19, Carty teaches the apparatus of claim 1, wherein the one or more actions comprise: steering one or more clients away from a first wireless node of the mesh network to a second wireless node of the mesh network (fig. 17, 18, ¶ [0085], The controller can determine whether mobile device 602 can be serviced by the access point in AP cell #12 526 and/or whether mobile device 604 can be serviced by the access point in AP cell #8 518.

In an example embodiment, in addition to determining which cells to activate, the controller or device implementing the power save algorithm determines the best channel for each cell to operate so as to minimize interference with adjacent cells. ¶ [0091]).
Regarding claim 11, Carty teaches the apparatus of claim 1, wherein the one or more actions comprise selecting one or more transmission parameters for one or more of the one or more wireless nodes of the mesh network, based on the information (figs. 5-24, ¶ [[0087]-¶ [0091], ¶ [0093], If the controller observes the number of mobile devices (clients) within an area decreasing, the controller may switch access points to power save mode and increase the coverage areas of one of the adjacent cells to compensate for the access points in power save mode. The coverage area for the access point of AP cell #10 1920 may be increased by increasing the transmit power, decreasing the SOP, and/or decreasing the CCA for the access point ).
Regarding claim 12, Carty teaches the apparatus of claim 11, wherein the one or more transmission parameters comprise at least one of a channel, a bandwidth, a modulation and coding scheme (MCS), or a number of spatial streams (¶ [0065], ¶ [0089], in addition to determining which cells to activate, the controller or device implementing the power save algorithm determines the best channel for each cell to operate so as to minimize interference with adjacent cells).
Regarding claim 13, Carty teaches the apparatus of claim 12, wherein the channel, bandwidth, or number of spatial streams are selected to allow the first wireless node of the mesh network to serve a number of clients so a second wireless node of the mesh network can enter an energy saving state (figs. 5-24, ¶ [[0087]-¶ [0091], ¶ [0093], If the controller observes the number of mobile devices (clients) within an area decreasing, the controller may switch access points to power save mode and increase the coverage areas of one of the adjacent cells to compensate for the access points in power save mode.

Claim Rejections - 35 USC § 103
6. 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.
7. 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.
8. 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.
9. Claims 4 and 7 are rejected under 35 U.S.C. 103 as being unpatentable over Vasseur in view of Chennichetty et al. (US 2021/0120454 A1, hereinafter “Chennichetty”).
Regarding claim 4, Vasseur teaches the apparatus of claim 3.
Vasseur does not explicitly teach wherein the one or more suitability criteria comprises the second wireless node being in closer proximity to a root node than one or more other wireless nodes of the mesh network.
Chennichetty teaches one or more suitability criteria comprises the second wireless node being in closer proximity to a root node than one or more other wireless nodes of the mesh network (fig. 1, ¶ [0041], ¶ [0044], In some implementations, the delay requirement may represent a maximum amount of delay (through a path to the root AP or gateway) that is acceptable for the QoS profile. A delay may be quantified as a time period or may be quantified as a hop count. A hop count refers to the number of links (between serving APs, intermediate APs, and the root AP) that are used in a path. A first path having a higher hop count may be considered as having a higher delay than a second path having a lower hop count. ¶ [0045], ¶ [0061], ¶ [0080], a gaming application with an AC_VO designation may perform better with a lower number of hops between the device and the root AP 110 (or the gateway device).
Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to set one or more suitability criteria as the second wireless node being in closer proximity to a root node than one or more other wireless nodes of the mesh network in the system of Vasseur to effectively and efficiently serve each client in the network (¶ [0046] of Chennichetty ).
Regarding claim 7, Vasseur teaches the apparatus of claim 6.
Vasseur does not explicitly teach wherein the suitability criteria also involves a capabilities match between the one or more clients and the second wireless node.
Chennichetty teaches wherein the suitability criteria also involves a capabilities match between the one or more clients and the second wireless node (¶ [0046], ¶ [0047]).
Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to set capabilities match between the one or more clients and the second wireless node as a suitability criteria in the system of Vasseur to effectively and efficiently serve each client in the network (¶ [0046] of Chennichetty ).
10. Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Vasseur in view of Wu et al. (CN 112911685 A, hereinafter “Wu”).
Regarding claim 7, Vasseur teaches the apparatus of claim 6.
Vasseur does not explicitly teach wherein the suitability criteria also involves a capabilities match between the one or more clients and the second wireless node.
However, it is well known in the art to select a wireless node (i.e., AP) based on matching capabilities between the client(s) and the wireless node(s), as evidenced by page 8 (SME according to the capability parameter stored locally, reading the logic AP information matched with the network capability in the locally stored BSSDescription; the logic AP capable of meeting the capability of all terminals as the candidate logic AP) of Wu.
Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to set capabilities match between the one or more clients and the second wireless node as a suitability criteria in the system of Vasseur to further enhance system efficiency and reliability.
11. Claims 8-10 are rejected under 35 U.S.C. 103 as being unpatentable over Vasseur in view of Kubota et al. (US 2023/0397083 A1, hereinafter “Kubota”).
Regarding claim 8, Vasseur teaches the apparatus of claim 1.
Vasseur does not explicitly teach wherein the information indicates the topology of the mesh network comprises a daisy chain of multiple hops; and the one or more actions comprise adjusting energy saving rules related to at least one backhaul link for a wireless node that is an end node of the daisy chain, if at least one condition is met.
Kubota teaches wherein the information indicates the topology of the mesh network comprises a chain of multiple hops (figs. 1, 7A-12); and the one or more actions comprise adjusting energy saving rules related to at least one backhaul link for a wireless node that is an end node of the daisy chain, if at least one condition is met (adjusting energy saving rules related to at least one backhaul link for a wireless node that is an end node of the daisy chain need not be performed if at least one condition is not met. See Ex Parte Schulhauser, Appeal No. 2013-007847 (PTAB April 28, 2016)).
Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to utilize a daisy chain of multiple hops and adjust energy saving rules related to at least one backhaul link for a wireless node that is an end node of the daisy chain, if at least one condition is met in the system of Vasseur to improve industrial applicability.
Regarding claim 9, Vasseur in view Kubota of teaches the apparatus of claim 8, wherein the at least one condition relates to a service level agreement (SLA) of a client served by the end node (Vasseur: figs.3, 4, ¶ [0037], ¶ [0049]).
Regarding claim 10, Vasseur in view of Kubota teaches the apparatus of claim 8.
Vasseur does not explicitly teach wherein at least one of: the at least one condition is met if the end node has entered an energy saving state; or the one or more actions comprise reducing a number of links in the at least one backhaul link.
Kubota teaches wherein at least one of: the at least one condition is met if the end node has entered an energy saving state; or the one or more actions comprise reducing a number of links in the at least one backhaul link (figs. 1, 4, 7A-12, ¶ [0063], a route that minimizes the route cost can be selected as the candidate route. At this time, the cost (link cost: link length) for each wireless link between access points 2 is set according to the available bandwidth and the number of connections of the user terminals 5. The shortest route from the user terminal 5 to the local service server 3 is obtained. ¶ [0068], ¶ [0069], when the number of hops (number of wireless links) of the target network (backhaul lines) is small and the throughput (total value of communication speed, amount of data traffic) is large, the power efficiency becomes high. ¶ [0070], ¶ [0083]).
Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to reduce a number of links in the at least one backhaul link in the system of Vasseur to improve power efficiency (¶ [0069] of Kubota).
12. Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Vasseur in view of Mao (CN 119605263 A).
Regarding claim 16, Vasseur teaches the apparatus of claim 1.
Vasseur does not explicitly teach wherein the one or more actions comprise adjusting at least one of an amount of control message signaling or frequency of control message signaling between wireless nodes of the mesh network, the adjustment being based on an energy savings policy.
However, it is well known in the art to adjust at least one of an amount of control message signaling or frequency of control message signaling between wireless nodes of the network based on an energy savings policy, as evidenced by Page 6 (the power saving function may include at least one of the following: The processor frequency is reduced, one or more functional components are closed, the radio interface is closed, the transmission or reception of signalling is reduced, the transmission rate is reduced, or the communication mechanism is adjusted) of Mao.
Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to save energy by adjusting at least one of an amount of control message signaling or frequency of control message signaling between wireless nodes of the mesh network based on an energy savings policy in the system of Vasseur to utilize conventional techniques in the art.
13. Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Vasseur in view of Mao as applied to claim 16 above, and further in view of Chen et al. (US 2019/0141708 A1, hereinafter “Chen”).
Regarding claim 17, Vasseur in view of Mao teaches the apparatus of claim 16.
Vasseur does not explicitly teach wherein the control message signaling comprises at least one of: a topology request, a topology response, a link status request, a link status response, a client status request, a status client response, an auto channel selection (ACS) request, an ACS response, a channel availability check (CAC) request, or a CAC response.
Chen the control message signaling comprises at least one of: a topology request, a topology response, a link status request, a link status response, a client status request, a status client response, an ACS request, an ACS response, a CAC request, or a CAC response (¶ [0251]).
Thus, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention, to exchange at least one of: a topology request, a topology response, a link status request, a link status response, a client status request, a status client response, an ACS request, an ACS response, a CAC request, or a CAC response in the system of Vasseur in view of Mao to further improve industrial applicability.
Response to Arguments
13. Applicant’s arguments with respect to Fuji et al. (JP 2015-019141 A) have been fully considered and are persuasive. The rejection under 35 U.S.C. § 102 has been withdrawn.
14. Applicant's arguments with respect to Vasseur et al. (US 2025/0039688 A1) and Carty et al. (US 2013/0329619 A1) have been fully considered but they are not persuasive.
15. Applicant argues “…Applicant submits that the Non-Final Office Action has also failed to adequately show that Vasseur teaches or suggests receiving "information regarding a topology of a mesh network" or performing "one or more actions to adjust power consumption at one or more wireless nodes of the mesh network" based on that information as recited in claim 1 and similar features recited in claims 18 and 20. Applicant submits that Vasseur does not describe a mesh network at all and certainly does not describe taking actions to adjust power consumption based on information regarding a mesh network topology…”
Examiner respectfully disagrees and submits that ¶ [0037] of the instant application discloses:
[0037] In some cases, STAs 104 may form networks without APs 102 or other equipment other than the STAs 104 themselves. One example of such a network is an ad hoc network (or wireless ad hoc network). Ad hoc networks may alternatively be referred to as mesh networks or peer-to-peer (P2P) networks. In some cases, ad hoc networks may be implemented within a larger wireless network such as the WLAN 100. In such examples, while the STAs 104 may be capable of communicating with each other through the AP 102 using communication links 106, STAs 104 also can communicate directly with each other via direct wireless communication links 110. Additionally, two STAs 104 may communicate via a direct communication link 110 regardless of whether both STAs 104 are associated with and served by the same AP 102. In such an ad hoc system, one or more of the STAs 104 may assume the role filled by the AP 102 in a BSS. Such a STA 104 may be referred to as a group owner (GO) and may coordinate transmissions within the ad hoc network. Examples of direct wireless communication links 110 include Wi-Fi Direct connections, connections established by using a Wi-Fi Tunneled Direct Link Setup (TDLS) link, and other P2P group connections.
Vasseur teaches receiving, via the at least one transceiver, information regarding a topology of a mesh network (figs. 1-5, ¶ [0030], ¶ [0051], ¶ [0022], The AP 102-1, AP 102-2, and AP 102-3 are neighboring (peer) APs. In some cases, a client STA may also communicate peer-to-peer with another client STA. ¶ [0026], ¶ [0027], the controller 130 may be communicatively coupled to (or integrated with) one or more databases 140. The database(s) 140 may include different types of metrics, including application performance metrics (e.g., frame retransmission counters, jitter, latency, delay, etc.), communication link metrics (e.g., received signal strength indication (RSSI), modulation and coding scheme (MCS), etc.), AP load information (including real-time load information and historical load information), and AP power on/power off state information (including real-time and historical power on/power off state information), ¶ [0038]); and performing, based on the information, one or more actions to adjust power consumption at one or more wireless nodes of the mesh network (figs. 1-4, ¶ [0030], the controller 230 includes logic for dynamically adapting the wireless topology of a network by dynamically powering off (or reducing the power of) one or more radios of one or more APs 102 deployed within an environment. The controller 230 may determine a number of the APs 102 to power off (or reduce the power of), based on a target SLA of one or more client STAs being served by the APs 102. ¶ [0031], ¶ [0032], ¶ [0035], ¶ [0037]-¶ [0039]).
Therefore, claims 1 and 18 are anticipated by Vasseur, as set forth above.
16. Applicant argues “…Applicant submits that the Non-Final Office Action has also failed to adequately show that Carty teaches or suggests receiving "information regarding a topology of a mesh network" or performing "one or more actions to adjust power consumption at one or more wireless nodes of the mesh network" based on that information as recited in claim 1 and similar features recited in claims 18 and 20. Applicant submits that Carty makes just a single mention of a mesh network (e.g., see Carty [0067]), but certainly does not describe taking actions to adjust power consumption based on information regarding a mesh network topology…”
Examiner respectfully disagrees and submits that Carty teaches receiving, via the at least one transceiver, information regarding a topology of a mesh network (figs. 1-31, ¶ [0048], ¶ [0067], Referring to FIG. 2, there is illustrated an access point (AP) 200 upon which an example embodiment is implemented. A PHY with RF circuitry may be employed instead of an Ethernet PHY if the distribution network (not shown) is a mesh network. ¶ [0102], ¶ [0123], At 3402, data is received from a plurality of access points about current network activity. For example, the data may include the number of associated clients, as well as throughput, data rate, signal to noise ratio (SNR), and/or Received Signal Strength Indication (RSSI) for each associated client. Based on the received data, a determination is made as to which access points (APS) currently have associated clients at 3404. ¶ [0073], ¶ [0087]- ¶ [0091], ¶ [0092], If the controller observes a number of mobile devices (clients) associating to one or more cells while some access points are in power save (sleep) mode, the controller may switch additional access points into operational mode. ¶ [0093], ¶ [0100]); and performing, based on the information, one or more actions to adjust power consumption at one or more wireless nodes of the mesh network (figs. 1-31, ¶ [0085], The controller can determine whether mobile device 602 can be serviced by the access point in AP cell #12 526 and/or whether mobile device 604 can be serviced by the access point in AP cell #8 518. In this example, mobile device 602 is in an area covered by both AP cell #8 518 and AP cell #12 526. Therefore, the controller can instruct (force) mobile device 602 to roam to the access point at AP cell #12 526. ¶ [0086], FIG. 18 illustrates the network of FIG. 16 after a forced roam (active grouping) of mobile device 602. Because mobile device 602 is now associated with AP cell #12 526, the access points in AP cell #3 506 and AP cell #4 508 can be switched to power save mode because they are no longer adjacent to a cell with an associated mobile device. ¶ [0087]- ¶ [0092], ¶ [0099]).
Therefore, claims 1 and 18 are anticipated by Carty, as set forth above.
Conclusion
17. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
