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 (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. 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. Claim(s) 25-26 and 31 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dizon et al (US Pub No. 2021/0257980, hereinafter Dizon) as applied to claims above, and further in view of Kim et al (US Pub No. 2021/0247952, hereinafter Kim). Regarding claim 25, Dizon teaches the method according to claim 23, wherein sending, by the terminal device, the volume adjustment message to the first electronic device comprises: when a device model of the first electronic device is the same as a device model of the second electronic device (¶ [0034], zone players can be the same model), sending, by the terminal device, the volume adjustment message to the first electronic device, wherein the volume adjustment message carries the first volume value of the terminal device, and the volume adjustment message indicates to the first electronic device to adjust a volume value output to the terminal device to the first volume value (¶ [0116], first message including volume adjustment sent between devices i.e. (controller 708 to zone player 702 (first device)). Dizon does not explicitly teach a device identifier. Kim teaches device identifiers included in exchange information between devices (See Kim ¶ [0099], device identifiers). It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have incorporated the device identifier information taught by Kim with the method taught by Dizon. Device identifiers provide a reliable method of device identification allowing for enhanced security between connected devices. Regarding claim 26, Dizon in view of Kim teaches the method according to claim 25, further comprising: obtaining, by the terminal device, a third volume value, wherein the third volume value is a volume value output to the terminal device before the first electronic device performs volume adjustment (See Dizon Fig 10, step 1002 user input at primary device (controller 708)); and wherein sending, by the terminal device, the volume adjustment message to the first electronic device comprises: when the first volume value is different from the third volume value, sending, by the terminal device, the volume adjustment message to the first electronic device (See Dizon abstract, second message including information for the volume of the playback device (zone player 702), wherein the volume is based on the adjusted volume). Regarding claim 31, Dizon teaches the method according to claim 23, further comprising: querying whether there is a fourth volume value (Fig 9, step 902 user input of zone player 702 (first device)), wherein the fourth volume value is a volume value that conforms to a use habit of the user when the user uses the first electronic device (Fig 7 & 9 & ¶ [0024], step 902 initial user input received from zone player 702 (first device). User input can be received at any device within the bonded zone (connected) allowing a volume change request to propagate throughout the bonded zone); and adjusting, by the terminal device, the playback volume based on the fourth volume value in response to detecting that the terminal device establishes a communication connection to the first electronic device and that the fourth volume value is queried (Fig 9 & ¶ [0091-0094], step 908 zone player 702 (first device) determined to be secondary device. Steps 910-914 send audio data including volume adjustment to controller 708 (primary device). Step 916 controller 708 (primary device) adjusts volume based on input.); and wherein obtaining, by the terminal device, the first volume value in response to detecting that the terminal device establishes the communication connection to the first electronic device comprises: obtaining, by the terminal device, the first volume value in response to detecting that the terminal device establishes the communication connection to the first electronic device and that the fourth volume value is not queried (Fig 9, step 912 user input information packet sent to primary device (controller 708) without a user input (fourth volume) at zone player 702 (first device)). Dizon does not explicitly teach a device identifier. Kim teaches device identifiers included in exchange information between devices (See Kim ¶ [0099], device identifiers). It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have incorporated the device identifier information taught by Kim with the method taught by Dizon. Device identifiers provide a reliable method of device identification allowing for enhanced security between connected devices. Claim(s) 29-30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dizon et al (US Pub No. 2021/0257980, hereinafter Dizon) as applied to claims above, and further in view of Cremer et al (US Pub No. 2021/0349683, hereinafter Cremer). Regarding claim 29, Dizon teaches the method according to claim 23, wherein sending, by the terminal device, the volume adjustment message to the first electronic device comprises: when a device model of the first electronic device is different from a device model of the second electronic device (¶ [0034], zone players can be the different models), wherein the first unit volume is a playback volume corresponding to a unit volume value of the second electronic device (Fig 7 & 9 & ¶ [0024], step 902 initial user input received from zone player 704 (second device). User input can be received at any device within the bonded zone (connected) allowing a volume change request to propagate throughout the bonded zone); and sending, by the terminal device, the volume adjustment information to the first electronic device (Fig 10, controller receives user input as state variable step 1002 and transmits the user input (volume adjustment) to connected device zone player 702 (first device) step 1008), wherein the volume adjustment information carries the first playback volume, the volume adjustment information indicates to the first electronic device to adjust, to a second volume value, a volume value output to the terminal device (¶ [0116], first message including volume adjustment sent between devices i.e. (controller 708 to zone player 702 (first device)). the second unit volume is a playback volume corresponding to a unit volume value of the first electronic device (Fig 7 & 9 & ¶ [0024], step 902 initial user input received from zone player 704 (second device). User input can be received at any device within the bonded zone (connected) allowing a volume change request to propagate throughout the bonded zone). Dizon does not explicitly teach determining, by the terminal device, a first playback volume based on the first volume value and a pre-stored first unit volume, the second volume value is a volume value that is determined by the first electronic device based on the first playback volume and a pre-stored second unit volume, and a playback volume corresponding to the second volume value is the same as the first playback volume. Cremer teaches dynamic volume adjustment, by the terminal device, a first playback volume (See Cremer Fig 4, target volume range 416) based on the first volume value (See Cremer Fig 4, input volume 408) and a pre-stored first unit volume (See Cremer Fig 4, classification gain value 410 for first classification group), the second volume value is a volume value that is determined by the first electronic device based on the first playback volume (See Cremer Fig 4, target volume range 416) and a pre-stored second unit volume (See Cremer Fig 4, classification gain value 410 for second classification group), and a playback volume corresponding to the second volume value is the same as the first playback volume (See Cremer Fig 4, target volume range 416). It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have incorporated the dynamic volume adjustment taught by Cremer with the method taught by Dizon. Dynamic volume adjustment is well known in the art and provides the user with several key benefits including consistent listening levels and a reduced need for user input. Regarding claim 30, Dizon in view of Cremer teaches the method according to claim 29, further comprising: obtaining, by the terminal device, a third volume value, wherein the third volume value is a volume output to the terminal device before the first electronic device performs volume adjustment (Fig 10, step 1002 user input at primary device (controller 708)); and wherein sending, by the terminal device, the volume adjustment message to the first electronic device comprises: when the first playback volume is different from a playback volume corresponding to the third volume value, sending, by the terminal device, the volume adjustment message to the first electronic device (Fig 10, controller receives user input as state variable step 1002 and transmits the user input (volume adjustment) to connected device zone player 702 (first device) step 1008). Allowable Subject Matter Claim 32 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
