Response to Arguments
Applicant's arguments filed 05/21/2026 have been fully considered but they are not persuasive.
In response to applicant’s argument in pages 11-19, the applicant asserts that “Yun and Haartsen, alone or in any combination, fail to disclose each and every element of amended independent claim 1. As such, independent claim 1 patentably defines over the cited art. Independent claim 11 has been similarly amended and is allowable over the art of record for at least the same reasons.” Examiner respectively disagrees.
As indicated by par. 64, 65 of HAARTSEN, “it is assumed that the primary ear piece 12p erroneously receives audio packet A 610a sent by smartphone 19. That is, the preamble (access code) and header are received correctly, but the CRC does not check and the packet is discarded by the primary ear piece 12p. This is indicated in FIG. 7A by a reduced-size reception, crossed out by an “X.” Consequently, the primary ear piece 12p will not send an ACK packet on the first piconet P1 530 at the next slot boundary as before, but instead will listen to the second piconet P2 540 at instant 654a. Since the secondary ear piece 12s has received the audio packet A successfully, it will send the ARX packet 652a on piconet P2 540 as before. The primary ear piece 12p is thus informed that the secondary ear piece 12s has the audio information that the primary ear piece 12p had to discard…. That is, secondary ear piece 12s may send an ARX packet 652b on piconet P2 540. If it had received the retransmission erroneously or had missed it completely, it would not send the ARX packet 652b, but this would have no consequence for the rest of the procedure. The primary ear piece 12p will not receive this ARX packet 652b, as it returns an ACK packet 613 to the smartphone 19 on piconet P1 530 at the same slot boundary. It then sends its own ARX packet 655 on piconet P2 540, thus informing the secondary ear piece 12s that it has received the audio information successfully. Since both ear pieces 12 have received the audio information, no further action is taken, apart from listening alternatively on piconet P1 530 (first slot of each frame) and piconet P2 540 (second slot). Since the audio packet 610b was acknowledged, the smartphone 19 will take no further action.” In this scenario, HAARTSEN indicates the primary ear piece 12p fails to receive audio packet transmitted by smartphone 19 but the secondary piece 12s received the audio packet in the first time period. The secondary piece 12s sends the ARX or share the information indicating the secondary piece 12s received the audio packet. The smartphone 19 does not receive the ACK from the primary ear piece 12p and retransmit the audio packet. As indicated the retransmitted audio packet is received by the primary ear piece 12p and sends the ARX or share information indicating the primary ear piece 12p received the retransmitted audio packet to the secondary ear piece 12s. As indicated by par. 65 of HAARTSEN, “secondary ear piece 12s may send an ARX packet 652b on piconet P2 540. If it had received the retransmission erroneously or had missed it completely, it would not send the ARX packet 652b”, the secondary ear piece 12s fails to receive the retransmitted audio packet but the primary ear piece 12P received the retransmitted audio packet and the ACK is sent by the primary ear piece 12p to the smartphone 19 to indicate the primary ear piece 12p and the second ear piece 12s received the audio packet. As indicated, the second ear piece 12s received the audio packet in the first time period but the primary ear piece 12p does not and the primary ear piece 12p received the retransmitted packet in the second time period but the secondary ear piece 12s does not and the primary ear piece 12p sends the ACK to the smartphone to indicate the primary ear piece 12p and the second ear piece 12s received the audio packet.
Therefore, HAARTSEN teaches “share second information about a received packet with the second electronic device indicating whether the first electronic device and the second electronic device each receive the data packet retransmitted from the third electronic device during a second time period after the first time period, the second information indicating that the another of the first electronic device or the second electronic device that did not receive the data packet during the first time period received the retransmitted data packet during the second time period, but that the one of the first electronic device and the second electronic device that received the data packet during the first time period did not receive the retransmitted data packet during the second time period…upon identifying that the first electronic device and the second electronic device each receive the data packet at least one time during the first time period and the second time period, transmit a response packet indicating an acknowledgment (ACK) to the third electronic device, even when the one of the first electronic device and the second electronic device that did receive the data packet during the first time period did not receive the retransmitted data packet during the second time period, thereby preventing the third electronic device from retransmitting the data packet.”
Therefore, the combination of YUN and HAARTSEN would teach the claims.
The rejection is maintained.

But, HAARTSEN et al. (US 20200396028) in a similar or same field of endeavor teaches share information about a received packet with the second electronic device to obtain first information indicating whether the first electronic device and the second electronic device each receive a data packet from the third electronic device (par. 64, 65, it will send the ARX packet 652a on piconet P2 540 as before. The primary ear piece 12p is thus informed that the secondary ear piece 12s has the audio information that the primary ear piece 12p had to discard… secondary ear piece 12s may send an ARX packet 652b on piconet P2 540.

share second information about a received packet with the second electronic device indicating whether the first electronic device and the second electronic device each receive the data packet retransmitted from the third electronic device during a second time period after the first time period (fig. 7A, par. 64, 65, it will send the ARX packet 652a on piconet P2 540 as before.

Thus, it would have been obvious to the person of ordinary skill in the art before the effectively filing date of the claimed invention to implement the system or method as taught by HAARTSEN in the system of YUN to transmit and retransmit packets in given time.
The motivation would have been to provide reliable transmission and synchronization between transmitter and receiver to provide orderly transmission and prevent collision.
Regarding claims 2, 12, YUN et al. (US 20190052961) teaches the first electronic device of claim 1, wherein the instructions are configured to, when executed, cause the first electronic device to,
in case that another first information indicates that the first electronic device and the second electronic device each receive the data packet, transmit another first response packet indicating ACK to the third electronic device (par. 112-116, In response to all of the first electronic device 101 and the second electronic device 102 successfully receiving the audio data packet, the first electronic device 101 may transmit an ACK to the audio source device 103 through the first wireless communication link 110).
However, YUN does not explicitly teach receive another data packet during the first time period.
But, HAARTSEN in a similar or same field of endeavor teaches the first electronic device and the second electronic device each receive another data packet during the first time period (fig. 6, 7A, par. 60, 64, 65, This packet 610 is sent by the smartphone 19 on piconet P1 530 and may be received by both the primary ear piece 12p and the secondary ear piece 12s. In response to the successful reception of packet 610, the primary ear piece 12p returns an acknowledgement (ACK) packet 611 to the smartphone 19).
Thus, it would have been obvious to the person of ordinary skill in the art before the effectively filing date of the claimed invention to implement the system or method as taught by HAARTSEN in the system of YUN to transmit and retransmit packets in given time.
The motivation would have been to provide reliable transmission and synchronization between transmitter and receiver to provide orderly transmission and prevent collision.

upon identifying that the first electronic device and the second electronic device each fail to receive another data packet, transmit a second response packet indicating a negative acknowledgement (NACK) to the third electronic device (par. 112-115, In response to even one of the first electronic device 101 and the second electronic device 102 not successfully receive the audio packet, the first electronic device 101 may transmit a NACK to the audio source device 103 through the first wireless communication link 110).
However, YUN does not explicitly teach receive another data packet at least one time during another first time period and another second time period.
But, HAARTSEN in a similar or same field of endeavor teaches upon identifying that the first electronic device and the second electronic device each fail to receive another data packet at least one time during another first time period and another second time period, indicate that the ACK not receive to the third electronic device (fig. 7A, par. 64, 65, Yet, since the smartphone 19 did not receive an ACK for the audio packet 610a, it may decide to directly retransmit packet 610b with the same audio information A as was contained in audio packet 610a).

Regarding claims 10, 20, YUN et al. (US 20190052961) teaches the first electronic device of claim 1,
wherein information about the received packet shared with the second electronic device includes at least one of
sequence number information about the data packet received from the third electronic device, operation code (opcode) information about the data packet received from the third electronic device, type information about the data packet received from the third electronic device, size information about the data packet received from the third electronic device, clock information about a time of receiving the data packet from the third electronic device, codec information related to the data packet received from the third electronic device, channel profile information related to the data packet received from the third electronic device, or received signal strength information about the data packet received from the third electronic device (par. 48, 133, 138, 158, the communication parameter may include Bluetooth device address (BD_ADDR), logical transport address (LT_ADDR), a native clock (CLKN) of a source (SRC) (e.g., the audio source device 103), a clock offset between the SRC and a sink (SNK) (e.g., the first electronic device 101), and/or an encryption parameter (e.g., key exchange) on a link between the SRC and the SNK; clock offset between the SRC and a SNK would indicating the clock information about a time of receiving the data packet from the third electronic device).
Regarding claim 22, 24, YUN does not teach the first electronic device of claim 1, wherein the instructions are configured to, when executed, cause the first electronic device to,
receive a first identification information of a data packet that the third electronic device re-transmitted and the second electronic device received during the second time period, and
identify whether the second electronic device received the data packet re- transmitted from the third electronic device, based on comparison of the first identification received from the second electronic device and a second identification information of the data packet that the electronic device received during the first time period.
But, HAARTSEN in a similar or same field of endeavor teaches receive a first identification information of a data packet that the third electronic device re-transmitted and the second electronic device received during the second time period (fig. 6, 7A, par. 60, 64, 65, it may decide to directly retransmit packet 610b with the same audio information A as was contained in audio packet 610a. In this example, this audio packet is received by primary ear piece 12p successfully...What will follow is the same procedure for successful packet arrival as was described in diagram 600. That is, secondary ear piece 12s may send an ARX packet 652b on piconet P2 540…The primary ear piece 12p will not receive this ARX packet 652b, as it returns an ACK packet 613 to the smartphone 19 on piconet P1 530 at the same slot boundary… Since both ear pieces 12 have received the audio information, no further action is taken, apart from listening alternatively on piconet P1 530 (first slot of each frame) and piconet P2 540 (second slot). Since the audio packet 610b was acknowledged, the smartphone 19 will take no further action; par. 72), and
identify whether the second electronic device received the data packet re- transmitted from the third electronic device, based on comparison of the first identification received from the second electronic device and a second identification information of the data packet that the electronic device received during the first time period (par. 72, If the second audio packet would have been a retransmission as visualized by audio packet 610b in FIG. 7A, which is a retransmission of packet 610a, ARX message 652b would also include the 12 LSBs of the Bluetooth clock as present at the leading edge of audio packet 610a. Based on the ARX message, the other ear piece knows which audio packets it failed to receive and can make a direct request for a specific audio packet by including the corresponding 12 LSBs of the Bluetooth clock in the RQA message).
Thus, it would have been obvious to the person of ordinary skill in the art before the effectively filing date of the claimed invention to implement the system or method as taught by HAARTSEN in the system of YUN to transmit and retransmit packets in given time.
The motivation would have been to improved radio performance.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
SUNG et al. (US 20190239054) teaches information about a received packet with the second electronic device to obtain first information indicating whether the first electronic device and the second electronic device each receive a data packet from the third electronic device during a first time period (par. 19, 20, The secondary headset 110B is arranged to send an acknowledgement ACK to the primary headset 110A), the first information indicating that one of the first electronic device and the second electronic device receive the data packet during the first time period and another of the first electronic device or the second electronic device did not receive the data packet during the first time period (par. 19, 20, the secondary headset 110B successfully sniffs to received and then decodes the (N+1)-th packet #(N+1), and the primary headset 110A fails to receive and decode the (N+1)-th packet #(N+1)),
based on a determination, based on the first information, that one of the first electronic device or the second electronic device fails to receive the data packet during the first time period, transmit a negative acknowledgment (NACK) to the third electronic device, such that the third electronic device retransmits the data packet during the second time period (par. 19, 20),
the information about the received packet with the second electronic device to obtain second information indicating whether the first electronic device and the second electronic device each receive the data packet retransmitted from the third electronic device during a second time period after the first time period (par. 19, 20), the second information indicating that one of the first electronic device or the second electronic device that did not receive the data packet during the first time period receive the retransmitted data packet during the second time period (par. 19, 20).
THOEN et al. (US 10348370) teaches neither the first or second wireless device 302, 304 receives the A2DP packet (i.e. both dashed lines), so neither the first or second wireless device 302, 304 transmits back an ACK packet. This will trigger the third wireless device 306 to retransmit the same A2DP packet (col. 8 lines 33-37).
