Office Action

§103
DETAILED ACTION The following is a final office action in response to applicant’s remarks/arguments 12/03/2025 for response of the office action mailed on 9/18/2025. Claims 1, 3-14, and 16-18 remain pending in the application. 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 . Response to Amendment The Amendment filed on 12/03/2025 has been entered. Applicant’s amendments to the Drawing have overcome each and every objection previously set forth in the Non-Final Rejection mailed on 9/18/2025. Response to Remarks/Arguments Applicant’s remarks/arguments (page 9-12), filed on 12/03/2025, with respect to claims 1, 14, and 17- 18 have been fully considered but are not persuasive. Regarding remarks in page 8, for independent claim 1, applicant asserts that Kakani does not discuss each node transmitting a wakeup interval for a different node. Examiner respectfully disagrees with the applicant. KAKANI et al. (US 2009/0279464 Al) discloses “The message may be sent over the direct data transfer link to the receiving mobile wireless device or alternately, it may be sent through an access point wireless device or any other wireless device to the receiving mobile wireless device. In the case of multi-band operation, where the STAs 100A and 100B are associated with the access point (AP) 50 in one band, but are using another band for their communication over the direct data transfer link 110, then the TSF of the access point (AP) 50 in the common band they share with the AP, is used. The frame 130AD may be sent through the access point (AP) wireless device 50 and forwarded in frame 130 DB to the receiving mobile wireless device STA 100B. A handshake protocol conducted by the transmitting STA 100A and the receiving STA 100B over either the common node path 115 through the AP. The common node path 115 is a data transfer path that includes the access point 50 or any other wireless station, Kakani: Fig. 7, [0011], [0037], [0041], [0069], [0083]”. Regarding remarks in page 8, for independent claim 1, applicant asserts that the cited references do not discuss transmitting a data packet that comprises a wakeup interval field in response to collecting data in a tag area network from a given other node. Kakani discloses “FIG. 1E is an example after the next active direct data transfer period, service period or session has started, showing the transmitting STA has resumed transmitting the buffered data to the receiving STA over the direct data transfer link, Kakani: Fig. 1E, [0022], [0068]-[0069]”. Regarding remarks in page 9, for dependent claim 17, applicant asserts that Applicant submits that the cited references discuss the reverse of what is claimed - identifying when a node transitions from a sleep state to a wakeup state. The Fig. 1 of application’s drawing notes that the wakeup interval may be a time interval between the wakeup intervals, which is same as “sleep time period (sleep state)”. Guo et al. (US 2018/0227846 Al) discloses “The sleep timer is used to schedule how long the node sleeps in a sleep interval. the battery powered node B 200 uses three timers to manage its sleep and wakeup schedules as well as transmission schedule: wakeup timer, sleep timer and TX timer. Before going to sleep, the node B sets wakeup timer. When wakeup timer expires, node B wakes up. Upon waking up, node B sets sleep timer. When sleep timer expires, node B goes to sleep. When node B wakes up, the node also sets TX timer. When TX timer expires, node B starts its TX period and transmits the buffered data packets., Guo: [0055], [0119]”. Regarding remarks in page 10, for dependent claim 14, applicant asserts that Prakash fails to cure the deficiencies of Shen/Kakani/Guo identified with respect to claim 1. Prakash et al. (US 2018/0167955 Al) discloses “if the child node receives an association response rejecting/denying the association request, the child node transmits the prioritized association request to the next available node within communication range of the child node, Prakash: [0050]”. Regarding remarks in page 11, for independent claim 18, applicant asserts that Applicant submits that the cited references discuss the reverse of what is claimed - identifying when a node transitions from a sleep state to a wakeup state. The Fig. 1 of application’s drawing notes that the wakeup interval may be a time interval between the wakeup intervals, which is same as “sleep time period (sleep state)”. Guo et al. (US 2018/0227846 Al) discloses “The sleep timer is used to schedule how long the node sleeps in a sleep interval. the battery powered node B 200 uses three timers to manage its sleep and wakeup schedules as well as transmission schedule: wakeup timer, sleep timer and TX timer. Before going to sleep, the node B sets wakeup timer. When wakeup timer expires, node B wakes up. Upon waking up, node B sets sleep timer. When sleep timer expires, node B goes to sleep. When node B wakes up, the node also sets TX timer. When TX timer expires, node B starts its TX period and transmits the buffered data packets., Guo: [0055], [0119]”. 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 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 of this title, 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 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. Claims 1, 3-13, and 16-18 are rejected under 35 U.S.C. 103 as being unpatentable over SHEN et al. (WO 2017/222449 Al, hereinafter “Shen”) in view of Guo et al. (US 2018/0227846 Al, hereinafter “Guo”) in further view of KAKANI et al. (US 2009/0279464 Al, hereinafter “Kakani”).

Multi-hop provisioning is a typical use case which requires rapid transfer of a relatively large amount of data and message transactions between PR, PAs and NDs. Provisioning agents are assigned by the provisioner node during the provisioning procedure. new device (node) away from the provisioner, will communicate with the provisioning agent (sink node), Shen: Page 2 Lines 6-22, Page 3 Lines 22-24, Page 11 Lines 26-29). Shen does not explicitly disclose: a payload of the data collected for transmission to the manager node from the given other node of the plurality of nodes; and However, in the same field of endeavor, Guo teaches: a payload of the data collected for transmission to the manager node from the given other node of the plurality of nodes (FIG. 3A shows a schematic of wakeup message 220, which can include a message type field 300 to indicate type of the message, a node ID field 310 to indicate ID of the battery powered node that transmits the wakeup message, a RX period length field 320 to announce length of the time period the node will be receiving, a TX period length field 330 to indicate length of the time period the node will transmit buffered data packets, and options field 340 for any other information.

One of ordinary skill in the art would have been motivated because it is possible to provide a system and a method for energy efficient management of multi-hop heterogeneous wireless networks including battery-powered nodes and mains-powered nodes (Guo: [0006]). Yet, Shen does not explicitly disclose: a wakeup interval field that identifies a wakeup interval of the given other node to each node between the given other node and the manager node to identify the wakeup interval of the given other node; and However, in the same field of endeavor, Kakani teaches: a wakeup interval field that identifies a wakeup interval of the given other node to each node between the given other node and the manager node to identify the wakeup interval of the given other node (the access point (AP) 50 can also relay communications between the mobile wireless devices (STAs) 1 00A, 100B, and 1 00C in the infrastructure BSS 70.

The message may be sent over the direct data transfer link to the receiving mobile wireless device or alternately, it may be sent through an access point wireless device or any other wireless device to the receiving mobile wireless device. In the case of multi-band operation, where the STAs 100A and 100B are associated with the access point (AP) 50 in one band, but are using another band for their communication over the direct data transfer link 110, then the TSF of the access point (AP) 50 in the common band they share with the AP, is used.

A handshake protocol conducted by the transmitting STA 100A and the receiving STA 100B over either the common node path 115 through the AP. The common node path 115 is a data transfer path that includes the access point 50 or any other wireless station, Kakani: Fig. 1B, Fig. 7, [0011], [0034]-[0037], [0037], [0041], [0069], [0083]); and Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Shen-Guo in view of Kakani in order to further modify a wakeup interval field that identifies a wakeup interval of the given other node to each node between the given other node and the manager node to identify the wakeup interval of the given other node from the teachings of Kakani. One of ordinary skill in the art would have been motivated because it is possible to have the enhanced packet forwarding where the AP is aware of existing direct communication (e.g. use of the highest priority for forwarded packet or placing forwarded packet to the head of the queue) (Kakani: [0077]). Regarding claim 3, Shen-Guo-Kakani teach all the claimed limitations as set forth in the rejection of claim 1 above.

The provisioning is concluded through the assigned provisioning agent node. If the message is same as one of the received routing request but the relay does not belong to the created route, the message is discarded, Shen: Page 4 Lines 14-18, Page 20 Lines 20-30).

Shen further discloses: The low-power wireless network system of claim 12, wherein the sink node transmits an unset packet to the particular node according to the unset command, and unsets the particular ID from a route table in which IDs of the nodes are set (A path P(UN) is created for each UN in a provisioning tree topology. The provisioner, PR, is added as a node to the path P(UN). If all new NDs have been joined in the network, the provisioning procedure is ended and the established optimized paths between a PR and a node not selected as a router may be removed, Shen: Page 27 Lines 2-29). Regarding claim 16, Shen-Guo-Kakani teach all the claimed limitations as set forth in the rejection of claim 1 above.

However, in the same field of endeavor, Guo teaches: The low-power wireless network system of claim 1, wherein a first node, among the nodes, transmits a first data packet comprising a first wakeup interval and the data to at least one of the sink node and a second node among the nodes (node uses wakeup message and active period extension notification message to announce its active period settings to neighbors. When node wakes up from sleep, the node transmits a wakeup message. wakeup message can include a message type field, a node ID field, a RX period length field, a TX period length field, and options field for any other information, Guo: [0066]-[0067]), and wherein the at least one of the second node and the sink node sets, in a set wakeup table, the first wakeup interval comprised in the first data packet, and transmits a second data packet to the first node according to the first wakeup interval (each node maintains a active period table that includes parent ID, parent RX period ending time and parent TX period ending time. these values are obtained in wakeup message or active period extension notification message. The active period table is used by a data node to select the best parent to send data packet at a given time, Guo: [0108]); Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Shen in view of Guo in order to further modify transmitting a first data packet comprising a first wakeup interval from a first node and the data and the first wakeup interval comprised in the first data packet and transmits a second data packet to the first node according to the first wakeup interval from the teachings of Guo. One of ordinary skill in the art would have been motivated because it is possible to provide a system and a method for energy efficient management of multi-hop heterogeneous wireless networks including battery-powered nodes and mains-powered nodes (Guo: [0006]). Regarding claim 17, Shen-Guo-Kakani teach all the claimed limitations as set forth in the rejection of claim 1 above. Shen does not explicitly disclose: The low-power wireless network system of claim 1, wherein the wakeup interval specifies when a given node of the plurality of nodes from which a given data packet originates will transition from a wakeup state to a sleep state. However, in the same field of endeavor, Guo teaches: wherein the wakeup interval specifies when a given node of the plurality of nodes from which a given data packet originates will transition from a wakeup state to a sleep state (The sleep timer is used to schedule how long the node sleeps in a sleep interval. the battery powered node B 200 uses three timers to manage its sleep and wakeup schedules as well as transmission schedule: wakeup timer, sleep timer and TX timer. Before going to sleep, the node B sets wakeup timer. When wakeup timer expires, node B wakes up. Upon waking up, node B sets sleep timer. When sleep timer expires, node B goes to sleep. When node B wakes up, the node also sets TX timer. When TX timer expires, node B starts its TX period and transmits the buffered data packets, Guo: [0055], [0119]). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Shen in view of Guo in order to further modify specifying the wakeup interval when a given node of the plurality of nodes from which a given data packet originates will transition from a wakeup state to a sleep state from the teachings of Guo. One of ordinary skill in the art would have been motivated because it is possible to provide a system and a method for energy efficient management of multi-hop heterogeneous wireless networks including battery-powered nodes and mains-powered nodes (Guo: [0006]).

After transmitting wakeup message, node starts RX process, Guo: [0120]). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Shen in view of Guo in order to further modify a payload of the data collected for transmission to the manager node from the given other node of the plurality of nodes and the wakeup interval specifying the originating node will transition from a wakeup state to a sleep state from the teachings of Guo. One of ordinary skill in the art would have been motivated because it is possible to provide a system and a method for energy efficient management of multi-hop heterogeneous wireless networks including battery-powered nodes and mains-powered nodes (Guo: [0006]). Yet, Shen does not explicitly disclose: a wakeup interval field that provides a wakeup interval of the originating node to each node of the plurality of nodes that receives the given data packet between the originating node and the manager node, However, in the same field of endeavor, Kakani teaches: a wakeup interval field that provides a wakeup interval of the originating node to each node of the plurality of nodes that receives the given data packet between the originating node and the manager node (the access point (AP) 50 can also relay communications between the mobile wireless devices (STAs) 1 00A, 100B, and 1 00C in the infrastructure BSS 70. FIG.1B shows the transmitting STA l00A inserting in the last message frame 120AB according to an embodiment, a specified time 126 when the next active direct data transfer period, service period or session will start. The message may be sent over the direct data transfer link to the receiving mobile wireless device or alternately, it may be sent through an access point wireless device or any other wireless device to the receiving mobile wireless device. In the case of multi-band operation, where the STAs 100A and 100B are associated with the access point (AP) 50 in one band, but are using another band for their communication over the direct data transfer link 110, then the TSF of the access point (AP) 50 in the common band they share with the AP, is used. The frame 130AD may be sent through the access point (AP) wireless device 50 and forwarded in frame 130 DB to the receiving mobile wireless device STA 100B. A handshake protocol conducted by the transmitting STA 100A and the receiving STA 100B over either the common node path 115 through the AP. The common node path 115 is a data transfer path that includes the access point 50 or any other wireless station, Kakani: Fig. 1B, Fig. 7, [0011], [0034]-[0037], [0037], [0041], [0069], [0083]); and Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Shen-Guo in view of Kakani in order to further modify a wakeup interval field that identifies a wakeup interval of the given other node to each node between the given other node and the manager node to identify the wakeup interval of the given other node from the teachings of Kakani. One of ordinary skill in the art would have been motivated because it is possible to have the enhanced packet forwarding where the AP is aware of existing direct communication (e.g. use of the highest priority for forwarded packet or placing forwarded packet to the head of the queue) (Kakani: [0077]). Claims 14 is rejected under 35 U.S.C. 103 as being unpatentable over Shen-Guo-Kakani and in further view of Prakash et al. (US 2018/0167955 Al, hereinafter “Prakash”). Regarding claim 14, Shen-Guo-Kakani teach all the claimed limitations as set forth in the rejection of claim 13 above. Shen-Guo do not explicitly disclose: The low-power wireless network system of claim 13, wherein, when the unsetting packet is received, the particular node deletes a priority route set in the tag area network, and transmits, to the tag area network, a route unset notification packet for notifying the unsetting. However, in the same field of endeavor, Prakash teaches: wherein, when the unsetting packet is received, the particular node deletes a priority route set in the tag area network, and transmits, to the tag area network, a route unset notification packet for notifying the unsetting (if the child node receives an association response rejecting/denying the association request, the child node transmits the prioritized association request to the next available node within communication range of the child node, Prakash: [0050]). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Shen-Guo-Kakani in view of Prakash in order to further modify the processing when the unsetting packet is received, the particular node deletes a priority route set in the tag area network and transmits to the tag area network a route unset notification packet for notifying the unsetting from the teachings of Prakash. One of ordinary skill in the art would have been motivated determining whether to transmit an association request with priority (Prakash: [0004]). Conclusion THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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 extension fee 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. In the case of amendments, applicant is respectfully requested to indicate the portion(s) of the specification which dictate(s) the structure relied on for proper interpretation and support, for ascertaining the metes and bounds of the claimed invention.
