CTNF 17/898,448 CTNF 99177 DETAILED ACTION Continued Examination Under 37 CFR 1.114 07-42-04 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office Action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 05/19/2026 has been entered and made of record. Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 Claims 21, 30 and 39 are amended. No new claim is/are added. Claims 21-40 are pending for examination. Response to Arguments Applicant’s response has been fully considered. Below are applicant’s main arguments and examiner’s response to those arguments: Applicant’s argument : (remark pages 9-11), filed on 05/19/2026, with respect to claim 21, ‘ independent claim 21 now recites … Liu teaches sending service discovery frames and channel switch times but does not expressly teach the coordination of the blackout period relative to the start of an availability window as claimed. In other words, Liu describes a localized hardware "Channel Switch Delay" meant to delay a single device's internal transmission chain. It fails to teach or suggest an active coordination link where multiple nodes mutually pause communication based on negotiated capabilities… Applicant respectfully requests that these rejections be withdrawn ’. Examiner’s response : Examiner respectfully disagrees. Liu teaches the device sends service discovery request including device capability attribute such as Channel Switch Time ( Liu: [FIG.13, [0091], [0104], [0194] ) and wait for Channel Switch Delay period before any transmission ( Liu: [FIG.13]; [0160] ). Seok teaches that the second device would include its Channel Switch Time in the Channel Switch Response in case that it requires a longer CST ( Seok: [0202], [0203] ). Therefore, combination of Liu and Seok teaches the device would wait for “Channel Switch Delay” period before any transmission based on the CST in Channel Switch Response (maximum of the first CST and the second CST) so that both the device and the second device could switch to new channel (neither device would initiate a transmission during the period), which teaches the subject matters as claimed. See the detailed Office Action bellow under 35 U.S.C. § 103 section. Applicant’s arguments (remark pages 9-11), filed on 05/19/2026, with respect to claims 21-40 have been considered but are moot in view of the new ground of rejection below which better address the claimed invention as amended. Double Patenting 08-33 AIA 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 § 2146 et seq. 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 filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual 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.

( US 20160165653 A1 ), hereinafter “Liu” . Per claim 21, 30 and 39: Regarding claim 21 , claim 21 recites limitations substantially the same as the combination of claim 2 and claim 6 of US Pat 655. These limitations are fully covered by the combination of claim 2 and claim 6 of US Pat 655. Regarding claim element, ‘ determine a blackout period as a duration equal to a maximum of the first CST and the second CST; refrain from transmitting data during the blackout period, wherein the blackout period is incurred immediately before a start of an availability window on the second channel; enforce the blackout period as a synchronized quiet interval across a Neighborhood Awareness Network (NAN) data path between the device and the second device such that neither device initiates a transmission until the maximum of the first CST and the second CST has elapsed ’, Claim 2 and claim 6 of US Pat 655 teaches after waiting at least for the duration specified by the CST parameter which is a maximum CST, but is silent on for a maximum of the first CST and the second CST. However It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to reasonably infer that the duration specified by the CST parameter taught by US Pat 655 may be the greater of the first CST and the second CST in order to support the device with less capability on CST. Therefore, claim 6 of US Pat 655 may be considered teaching after waiting at least for the greater of the first CST and the second CST, in another word, determine a blackout period as a duration equal to a maximum of the first CST and the second CST; refrain from transmitting data during the blackout period, wherein the blackout period is incurred immediately before a start of an availability window on the second channel. Combination of claim 2 and claim 6 of US Pat 655 do not teach, but Liu in the same field of endeavor teaches ‘ a first device capability attribute ’ ( Liu: [0104]: “send service discovery frame (SDF) 416 which may include service information, capability information” ); ‘ wherein the service discovery request frame comprises a first device capability attribute, wherein the first device capability attribute comprises a first channel switch time (CST) associated with a switch to a second channel ’ ( Liu: [0194]: each device “may denote a preferred channel list for new a NAN datapath … on channel switch time points”, device capability attribute may comprise CST associated with a given new channel (a period during which the device is unavailable to transmit or receive immediately before switching to a given new channel) ); ‘ wherein the first CST and the second CST are included in respective Device Capability attributes of the first and second devices, and indicate respective blackout periods immediately before channel switching during which the corresponding device is unavailable to transmit or receive ’ ( Liu: [0104]: “send service discovery frame (SDF) 416 which may include service information, capability information”; [0091]: “device A sends P2P service discovery response 728, which can include any or all of setup attributes”; [0194]: each device “may denote a preferred channel list for new a NAN datapath … on channel switch time points”; [FIG.13]: “Channel Switch Delay”, “Post NAN Discovery Activities”, “Ch-6”, “Post-NAN Operation channels”; device capability attribute would include the first CST and the second CST of the first and second devices indicate respective blackout periods immediately before channel switching during which the corresponding device is unavailable to transmit or receive ). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Liu’s teaching with that of combination of claim 2 and claim 6 of US Pat.655 in order to include device capability attribute such as channel switch time points in service discovery frame (see reference quotes in element above).

Claim Rejections - 35 USC § 103 07-06 AIA 15-10-15 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 (i.e., changing from AIA to pre-AIA) 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. 07-20-aia AIA 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. 07-23-aia AIA 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. 07-20-02-aia AIA 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. 07-21-aia AIA Claim s 21-22, 24-31, and 33-40 are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. ( US 20160165653 A1 ), hereinafter “Liu”, in view of Seok et al. ( US 20140086200 A1 ), hereinafter “Seok” . Per claim 21, 30 and 39: Regarding claim 21 , Liu teaches ‘ A device’ ( Liu: [FIG.3]: “Client Station” ); ‘the device comprising processing circuitry ( Liu: [FIG.3]: “Circuity” ); ‘ coupled to’ ( this is implied ); ‘storage’ ( Liu: [FIG.3]: “Memory” ); ‘ the processing circuitry configured to : cause to send a service discovery request frame to a second device on a first channel ’ ( Liu: [FIG.13]: “Service Discovery”, “Ch-6”, “Ch-149”; [0091]: “P2P service discovery request”; [0104]: “send service discovery frame” ); ‘ wherein the service discovery request frame comprises a first device capability attribute ’ ( Liu: [0104]: “send service discovery frame (SDF) 416 which may include service information, capability information” ); ‘ wherein the service discovery request frame comprises a first device capability including a first channel switch time (CST) indicating a period during which the device is unavailable to transmit or receive immediately before switching to a second channel ’ ( Liu: [0194]: each device “may denote a preferred channel list for new a NAN datapath … on channel switch time points”, device capability attribute may comprise CST associated with a given new channel (a period during which the device is unavailable to transmit or receive immediately before switching to a given new channel) ); ‘ identify a service discovery response frame received from the second device , wherein the service discovery response frame comprises a second device capability attribute ’ ( Liu: [0091]: “device A sends P2P service discovery response 728, which can include any or all of setup attributes”, the request device may receive service discovery response from its peer, which may comprise response device capability attribute for setup ). Liu does not expressly teach, but Seok in the same field of endeavor teaches ‘ a second CST indicating a period during which the second device is unavailable to transmit or receive immediately before switching to the second channel ’ ( Seok: [0202]: “The AP having received the channel switch request frame including the switch time information transmits the channel switch response frame to the STA”; [0203]: “the switch time information established by the AP may be contained in the Channel Switch Response frame”, another CST associated with the given channel from response device (a period during which the second device is unavailable to transmit or receive immediately before switching to the second channel) ). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Seok’s teaching with that of Liu in order for response device to include its CST in the device capability attribute if it needs a larger CST than its request peer (see reference quotes in element above). Combination of Liu and Seok teaches ‘ determine a blackout period as a duration equal to a maximum of the first CST and the second CST’ ( Liu: [FIG.13]: “Channel Switch Delay”; [0160]: “In addition, note that there may be a delay, such as channel switch delay 1202, associated with a NAN device moving (or tuning) from one channel to another channel”. Seok: [0203]: “If a predetermined time needed for the STA moving (or switching) to the selected sub-channel is shorter than another time needed for the AP moving (or switching) to the selected sub-channel, the switch time information established by the AP may be contained in the Channel Switch Response frame. In this case, the STA may communicate with the AP using the selected sub-channel after lapse of the switch time contained in the Channel Switch Response frame”, would send a transmission after waiting for a determined CST to be a maximum of the first CST and the second CST (a blackout period as a duration equal to a maximum of the first CST and the second CST) ); ‘refrain from transmitting data during the blackout period ’ (discussed in element above); ‘ wherein the blackout period is incurred immediately before a start of an availability window on the second channel ’ ( Liu: [FIG.13]: “Ch-6”, “Ch-149”, “Channel Switch Delay” is immediately before a start of an availability window on the second channel; [0160]: “In addition, note that there may be a delay, such as channel switch delay 1202, associated with a NAN device moving (or tuning) from one channel to another channel” ); ‘ enforce the blackout period as a synchronized quiet interval across a Neighborhood Awareness Network (NAN) data path between the device and the second device such that neither device initiates a transmission until the maximum of the first CST and the second CST has elapsed ’ ( Liu: [FIG.13]: “Ch-6”, “Ch-149”, “Channel Switch Delay” before any transmission; [0194]: each device “may denote a preferred channel list for new a NAN datapath … on channel switch time points”. Seok: [0203]: “If a predetermined time needed for the STA moving (or switching) to the selected sub-channel is shorter than another time needed for the AP moving (or switching) to the selected sub-channel, the switch time information established by the AP may be contained in the Channel Switch Response frame. In this case, the STA may communicate with the AP using the selected sub-channel after lapse of the switch time contained in the Channel Switch Response frame”, response device would include its CST in Channel Switch Response if it requires a longer CST. The device would wait for “Channel Switch Delay” period before any transmission based on the CST in Channel Switch Response ((maximum of the first CST and the second CST)) so that both the device and the second device could switch to new channel (neither device would initiate a transmission during the period) => enforce the blackout period as a synchronized quiet interval for both devices to switch to the new channel ); ‘ cause to send a transmission to the second device over the second channel after the blackout period ends and within the availability window ’ ( Liu: [FIG.12]; [FIG.13]: “Channel Switch Delay”, “Post NAN Discovery Activities”, “Ch-6”, “Post-NAN Operation channels”. Seok: [0203]: “the STA may communicate with the AP using the selected sub-channel after lapse of the switch time”; cause a transmission to the second device over the second channel after the blackout period ends and within the availability window ); ‘ wherein the first CST and the second CST are included in respective Device Capability attributes of the first and second devices indicate respective blackout periods immediately before channel switching during which the corresponding device is unavailable to transmit or receive’ ( Liu: [0104]: “send service discovery frame (SDF) 416 which may include service information, capability information”; [0091]: “device A sends P2P service discovery response 728, which can include any or all of setup attributes”; [0194]: each device “may denote a preferred channel list for new a NAN datapath … on channel switch time points”; [FIG.13]: “Channel Switch Delay”, “Post NAN Discovery Activities”, “Ch-6”, “Post-NAN Operation channels”; device capability attribute would include the first CST and the second CST of the first and second devices indicate respective blackout periods immediately before channel switching during which the corresponding device is unavailable to transmit or receive ). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Seok’s teaching of device with less capable in channel switching (needs longer channel switching time) would include its desired CST value in response message with that of Liu in order for response device to include its CST in the device capability attribute if it needs a larger CST than its request peer (see reference quotes in element above). Regarding claim 30 , claim 30 recites the memory and the method implemented by the device of claim 21 (see rejection of claim 21 above). Regarding claim 39 , claim 39 recites the method implemented by the device of claim 21 (see rejection of claim 21 above). Per claim 22, 31 and 40: Regarding claim 22 , combination of Liu and Seok teaches the device of claim 21 (discussed above). Combination of Liu and Seok teaches ‘ wherein the first CST and the second CST are in units of microseconds ’ ( Liu: [TABLE 16]: “Channel Switch Timing element to switch channels, in units of microseconds” ); ‘ wherein the first CST is a first maximum channel switch time and the second CST is a second maximum channel switch time ’ ( Liu: [0194]: each device “may denote a preferred channel list for new a NAN datapath … on channel switch time points”; [0158]: “P2P group may be created for two or more devices to exchange data with each other”. Seok: [0203]: “If a predetermined time needed for the STA moving (or switching) to the selected sub-channel is shorter than another time needed for the AP moving (or switching) to the selected sub-channel, the switch time information established by the AP may be contained in the Channel Switch Response frame. In this case, the STA may communicate with the AP using the selected sub-channel after lapse of the switch time contained in the Channel Switch Response frame”; for a given channel in the list, CST may be the maximum one among the group ). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Seok’s teaching with that of Liu in order support the device with least capability on CST in a P2P group (see reference quotes in element above). Regarding claim 31 , claim 31 recites the memory and the method implemented by the device of claim 22 (see rejection of claim 22 above). Regarding claim 40 , claim 40 recites the method implemented by the device of claim 22 (see rejection of claim 22 above). Per claim 24 and 33 : Regarding claim 24 , combination of Liu and Seok teaches the device of claim 21 (discussed above). Liu teaches ‘ wherein the transmission to the second device over the second channel is preceded by a random backoff time ’ ( Liu: [FIG.13]: “Ch-6”, “Ch-149”, “Post NAN Discovery Activities”; [0184]: “the NAN device may conduct a random backoff from the beginning of a selected DWE before transmitting”; transmission over the second channel may be preceded by a random backoff time ). Regarding claim 33 , claim 33 recites the memory and the method implemented by a device similar as in claim 24 (see rejection of claim 24 above). Per claim 25 and 34: Regarding claim 25 , combination of Liu and Seok teaches the device of claim 21 (discussed above). Liu teaches ‘wherein the transmission to the second device over the second channel is done at a start of a discovery window (DW)’ ( Liu: [FIG.13]: “NAN DW”, “Post NAN Discovery Activities”, “Ch-6”, “Ch-149”, transmission over the second channel may be done at a start of a discovery window (DW) ). Regarding claim 34 , claim 34 recites the memory and the method implemented by the device of claim 25 (see rejection of claim 25 above). Per claim 26 and 35: Regarding claim 26 , combination of Liu and Seok teaches the device of claim 21 (discussed above). Liu teaches ‘ cause to send a synchronization frame to the second device ’ ( Liu: [FIG.13]: “Post NAN Discovery Activities”, “Ch-6”, “Ch-149”; [0160]: “post-NAN operation channels, may carry … synchronization beacons”, may send a synchronization frame to the second device ). Regarding claim 35 , claim 35 recites the memory and the method implemented by the device of claim 26 (see rejection of claim 26 above). Per claim 27 and 36: Regarding claim 27 , combination of Liu and Seok teaches the device of claim 21 (discussed above). Liu teaches ‘ indicate one or more availability windows on the first channel and the second channel during a NAN data path connection setup ’ ( Liu: [0020]: “NAN datapath setup”; [0022]: “availability window”; [FIG.12]: availability window on Ch-149 and Ch-36; [0155]: “FIG. 12 illustrates signaling for scheduling a further availability window”; may indicate one or more availability windows on the first channels during a NAN data path connection setup ). Regarding claim 36 , claim 36 recites the memory and the method implemented by the device of claim 27 (see rejection of claim 27 above). Per claim 28 and 37: Regarding claim 28 , combination of Liu and Seok teaches the device of claim 21 (discussed above). Liu does not expressly teach, but Seok teaches ‘ wherein the first CST indicate a time where the device is not available to transmit or receive data ’ ( Seok: [0204]: “In addition, the Channel Switch Request frame may include duration information. The duration information requested for the AP may indicate that the STA will use the selected sub-channel during only a specific time corresponding to the duration value contained in the Channel Switch Request frame”; the request device would indicate the time outside its duration may be not available to transmit or receive data ). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Seok’s teaching with that of Liu for request device to indicate its available duration so that its peer device may avoid communications outside of the available time (see reference quotes in element above). Regarding claim 37 , claim 37 recites the memory and the method implemented by the device of claim 28 (see rejection of claim 28 above). Per claim 29 and 38: Regarding claim 29 , combination of Liu and Seok teaches the device of claim 21 (discussed above). Liu does not expressly teach, but Seok teaches ‘ wherein the second CST indicates a time where the second device is not available to transmit or receive data ’ ( Seok: [0205]: “The duration information may also be contained in the Channel Switch Response frame … thus defer a channel access by establishing an NAV corresponding to a specific time”, the response device would indicate the time outside its duration may be not available to transmit or receive data ). Regarding claim 38 , claim 38 recites the memory and the method implemented by the device of claim 29 (see rejection of claim 29 above) . 07-21-aia AIA Claim s 23 and 32 are rejected under 35 U.S.C. 103 as being unpatentable over combination of Liu and Seok as applied to claim 21 above, further in view of Gossain et al. ( US 20100103850 A1 ), hereinafter “Gossain” . Per claim 23 and 32: Regarding claim 23 , combination of Liu and Seok teaches the device of claim 21 (discussed above). Combination of Liu and Seok does not expressly teach, but Gossain in the same field of endeavor teaches ‘ wherein a size of a field indicating the first CST or the second CST is 2 octets ’ ( Gossain: [FIG.5]: Channel Switch duration or start count; [0038]: either Channel Switch duration or start count ("CST parameter") in the message have a size of 2 octets ). It would have been obvious to one of the ordinary skill in the art before the effective filling date of the claimed invention to combine Gossain’s teaching with that of combination of Liu and Seok in order to provide a method and apparatus to select a channel in a wireless communication system to facilitate a smooth channel switch operation ( Gossain: [0039]: “to facilitate the scanning procedure at AP/IAP … a Mesh Channel Switch Announcement (M-CSA) (shown in FIG. 6) to indicate its future channel of operation” ). Regarding claim 32 , claim 32 recites the memory and the method implemented by the device of claim 23 (see rejection of claim 23 above).
