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. 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 non-obviousness. 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. Claims 1-3, 6, 13-15, 26-27, and 30-33 are rejected under 35 U.S.C. 103 as being unpatentable over Lindner et al (US20160037310A1) (hereinafter "Lindner ") in view of Jorgovanovic et al (US11153678B1) (hereinafter "Jorgovanovic"). Regarding claim 1, Lindner discloses a method of communicating, comprising: receiving, at a first headset, a voice input from a user, wherein the voice input comprises a spoken operational input requesting voice communication and a spoken name associated with a contact in a workgroup ([0099] The first mobile device 102 may determine whether a detected audio signal is a recognized voice command to a group communication server in block 1106. In some embodiments, this may include analyzing the detected audio signal (e.g., using voice recognition software) to determine if it corresponds to a command to the group communication server. In embodiments, the first mobile device 102 may analyze the detected audio signal for particular keyword(s) associated with a command, for example. [0101] The voice command may be any command used in a group communication session, such a command to commence a communication session with a particular communication group, to terminate the session, to add or drop group members from a communication session, to send or download media files, and so forth.); performing, by a processor of the first headset, speech recognition on the voice input to identify the spoken operational input and to identify the spoken name ([0099] The first mobile device 102 may determine whether a detected audio signal is a recognized voice command to a group communication server in block 1106. In some embodiments, this may include analyzing the detected audio signal (e.g., using voice recognition software) to determine if it corresponds to a command to the group communication server. In embodiments, the first mobile device 102 may analyze the detected audio signal for particular keyword(s) associated with a command, for example.); generating, through the voice communication channel, a voice communication session between the first headset and the second headset, wherein the voice communication session allows voice communication between the first headset and the at least one second headset in a full-duplex communication mode ([0077] In block 612 of method 601, the first mobile device 201 may establish a full-duplex communication channel with at least one other (i.e., second) mobile device. The first mobile device 201 may communicate with the at least one second mobile device over the full-duplex communication channel in block 614.). Lindner fails to disclose a method, comprising: generating, via the first headset, a voice communication channel between the first headset and a second headset assigned to the identified contact in the workgroup. However, Jorgovanovic discloses a method, comprising: generating, via the first headset, a voice communication channel between the first headset and a second headset assigned to the identified contact in the workgroup (Col. 3, Ln. 30-35: In some instances, configuring the wireless headphones as walkie-talkies may involve establishing a two-way voice communication channel between the first wireless headphone and the second wireless headphone over the two-way voice communication channel, the wireless headphones may exchange audio data corresponding to user speech. Col. 7, Ln. 26-33: The first user 100 and/or the second user 102 may also utilize the wireless headphones 106 to perform additional commands using one or more predefined keywords or wake words. For instance, the first user 100 and/or the second user 102 may request that the wireless headphones 106 stream music, control a secondary device (e.g., turn on a TV, etc.), perform a phone call using the mobile device 108, respond to various commands, and so forth.).

Regarding claim 4, Lindner, as modified by Jorgovanovic, fails to disclose the method, wherein the at least one second headset comprises a plurality of second headsets, wherein the first headset and the plurality of second headsets form a workgroup, and wherein the voice communication channel is generated between the first headset and the plurality of second headsets in the workgroup. However, Brown discloses the method, wherein the at least one second headset comprises a plurality of second headsets, wherein the first headset and the plurality of second headsets form a workgroup, and wherein the voice communication channel is generated between the first headset and the plurality of second headsets in the workgroup ([0045] Preferably the headset 212 is configured to be capable of establishing communication with a plurality of headsets, to allow for a group communication between three or more users of headsets. Furthermore, it is envisaged that where group communication is supported a user is able to broadcast to all wireless headsets within range of its wireless headset.). Lindner, as modified by Jorgovanovic, and Brown are considered to be analogous to the claimed invention because both are in the same endeavor of two-way wireless headsets. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Lindner, as modified by Jorgovanovic, and Brown to create the method, wherein the at least one second headset comprises a plurality of second headsets, wherein the first headset and the plurality of second headsets form a workgroup, and wherein the voice communication channel is generated between the first headset and the plurality of second headsets in the workgroup. The motivation to combine both references would come from the need to allow simultaneous communication between multiple entities. Regarding claim 16, Lindner, as modified by Jorgovanovic, fails to disclose the system, wherein the at least one second headset comprises a plurality of second headsets, wherein the first headset and the plurality of second headsets form a workgroup, and wherein the processor is further configured to generate the voice communication channel between the first headset and the plurality of second headsets in the workgroup. However, Brown discloses the system, wherein the at least one second headset comprises a plurality of second headsets, wherein the first headset and the plurality of second headsets form a workgroup, and wherein the processor is further configured to generate the voice communication channel between the first headset and the plurality of second headsets in the workgroup ([0045] Preferably the headset 212 is configured to be capable of establishing communication with a plurality of headsets, to allow for a group communication between three or more users of headsets. Furthermore, it is envisaged that where group communication is supported a user is able to broadcast to all wireless headsets within range of its wireless headset.). Lindner, as modified by Jorgovanovic, and Brown are considered to be analogous to the claimed invention because both are in the same endeavor of two-way wireless headsets. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Lindner, as modified by Jorgovanovic, and Brown to create the system, wherein the at least one second headset comprises a plurality of second headsets, wherein the first headset and the plurality of second headsets form a workgroup, and wherein the processor is further configured to generate the voice communication channel between the first headset and the plurality of second headsets in the workgroup. The motivation to combine both references would come from the need to allow simultaneous communication between multiple entities. Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Lindner in view of Jorgovanovic, as applied to claims 1, 13, or 26 above, and further in view of Barnes et al (US20120096490A1) (hereinafter "Barnes"). Regarding claim 6, Lindner, as modified by Jorgovanovic, fails to disclose the method, further comprising generating a first alert including at least one of an audible alert and a haptic alert indicating that the voice communication session has been initiated. However, Barnes discloses the method, further comprising generating a first alert including at least one of an audible alert and a haptic alert indicating that the voice communication session has been initiated ([0419] One example embodiment of a device 101 includes hardware and computer programming (computer code segments) for performing the following steps: [0439] receiving a mobile telephone communication while presenting an audio presentation to the user an notifying the user of the received telephone communication through a vibratory alert and/or an audible alert;). Lindner, as modified by Jorgovanovic, and Barnes are considered to be analogous to the claimed invention because both are in the same endeavor of notifying a user of an event. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Lindner, as modified by Jorgovanovic, and Barnes to create the method, further comprising generating a first alert including at least one of an audible alert and a haptic alert indicating that the voice communication session has been initiated. The motivation to combine both references would come from the need to notify a user of an event through visual, auditory, or tactile means in case a certain method is not available. Claims 8, 20, 23, and 35 are rejected under 35 U.S.C. 103 as being unpatentable over Lindner in view of Jorgovanovic, as applied to claims 1, 13, or 26 above, and further in view of Subbaramoo et al (US20130316687A1) (hereinafter "Subbaramoo"). Regarding claim 8, Lindner, as modified by Jorgovanovic, fails to disclose the method, further comprising: determining a time duration elapsed since a termination of a last voice communication in the voice communication session; and terminating the voice communication session in response to the time duration exceeding a predetermined time threshold. However, Subbaramoo discloses the method, further comprising: determining a time duration elapsed since a termination of a last voice communication in the voice communication session; and ([0102] When the device 102 detects silence (i.e., determination block 1120="Yes"), the detected silence may trigger the start of a timeout period. The timeout period may have a duration that is sufficient to infer that the user has finished speaking and would like to relinquish control of the floor (e.g., generally around 1 second or more)) terminating the voice communication session in response to the time duration exceeding a predetermined time threshold ([0102] When the timeout period expires (i.e., determination block 1122="Yes"), the device 102 may close the communication channel in block 1124 and send a message to the group communication server relinquishing control of the floor in block 1126.). Lindner, as modified by Jorgovanovic, and Subbaramoo are considered to be analogous to the claimed invention because both are in the same endeavor of establishing a communication link between two devices. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Lindner, as modified by Jorgovanovic, and Subbaramoo to create the method, further comprising: determining a time duration elapsed since a termination of a last voice communication in the voice communication session; and terminating the voice communication session in response to the time duration exceeding a predetermined time threshold. The motivation to combine both references would come from the need to terminate a link when it is no longer needed to save system resources. Regarding claim 20, Lindner, as modified by Jorgovanovic, fails to disclose the system, wherein the processor is further configured to: determine a time duration elapsed since a termination of a last voice communication in the voice communication session; and terminate the voice communication session in response to the time duration exceeding a predetermined time threshold. However, Subbaramoo discloses the system, wherein the processor is further configured to: determine a time duration elapsed since a termination of a last voice communication in the voice communication session; and ([0102] When the device 102 detects silence (i.e., determination block 1120="Yes"), the detected silence may trigger the start of a timeout period. The timeout period may have a duration that is sufficient to infer that the user has finished speaking and would like to relinquish control of the floor (e.g., generally around 1 second or more)) terminate the voice communication session in response to the time duration exceeding a predetermined time threshold ([0102] When the timeout period expires (i.e., determination block 1122="Yes"), the device 102 may close the communication channel in block 1124 and send a message to the group communication server relinquishing control of the floor in block 1126.). Lindner, as modified by Jorgovanovic, and Subbaramoo are considered to be analogous to the claimed invention because both are in the same endeavor of establishing a communication link between two devices. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Lindner, as modified by Jorgovanovic, and Subbaramoo to create the system, wherein the processor is further configured to: determine a time duration elapsed since a termination of a last voice communication in the voice communication session; and terminate the voice communication session in response to the time duration exceeding a predetermined time threshold. The motivation to combine both references would come from the need to terminate a link when it is no longer needed to save system resources. Regarding claim 23, Lindner, as modified by Jorgovanovic, discloses the system, further comprising a communication controller communicably coupled to the first headset and the at least one second headset, wherein the processor is further configured to generate the voice communication channel between the first headset and the at least one second headset through the communication controller (Col. 9, Ln. 33-40: the interface(s) 208 of the first wireless headphone 106(1) may include a Bluetooth interface 210, a BLE interface 212, and/or a Bluetooth HFP protocol interface 214. However, in some instances, the first wireless headphone 106(1) may include additional interface(s) 208, such as an NFMI interface that allows the first wireless headphone 106(1) to transmit audio data with the second wireless headphone 106(2).). Lindner, as modified by Jorgovanovic, fails to disclose the system, wherein the communication controller is configured to: determine a time duration elapsed since a termination of a last voice communication in the voice communication session; and terminate the voice communication session in response to the time duration exceeding a predetermined time threshold However, Subbaramoo discloses the system, wherein the communication controller is configured to: determine a time duration elapsed since a termination of a last voice communication in the voice communication session; and ([0102] When the device 102 detects silence (i.e., determination block 1120="Yes"), the detected silence may trigger the start of a timeout period. The timeout period may have a duration that is sufficient to infer that the user has finished speaking and would like to relinquish control of the floor (e.g., generally around 1 second or more)) terminate the voice communication session in response to the time duration exceeding a predetermined time threshold ([0102] When the timeout period expires (i.e., determination block 1122="Yes"), the device 102 may close the communication channel in block 1124 and send a message to the group communication server relinquishing control of the floor in block 1126.).

Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Lindner, as modified by Jorgovanovic, and Subbaramoo to create the headset, wherein the processor is further configured to: determine a time duration elapsed since a termination of a last voice communication in the voice communication session; and terminate the voice communication session in response to the time duration exceeding a predetermined time threshold. The motivation to combine both references would come from the need to terminate a link when it is no longer needed to save system resources. Claim 28 is rejected under 35 U.S.C. 103 as being unpatentable over Lindner in view of Jorgovanovic, as applied to claims 1, 13, or 26 above, and further in view of Broadley et al (US20160302029A1) (hereinafter "Broadley"). Regarding claim 28, Lindner, as modified by Jorgovanovic, fails to disclose the headset, further comprising at least one headband, wherein the at least one earpiece comprises a first earpiece and a second earpiece, and wherein the first earpiece and the second earpiece are interconnected through the at least one headband. However, Broadley discloses the headset, further comprising at least one headband, wherein the at least one earpiece comprises a first earpiece and a second earpiece, and wherein the first earpiece and the second earpiece are interconnected through the at least one headband ([0022] As used and defined herein, the term “headset” refers to a communications headset that consists of two ear pieces that cover the ears of the user, and a headband that couples to the earpieces to provide support for the earpieces). Lindner, as modified by Jorgovanovic, and Broadley are considered to be analogous to the claimed invention because both are in the same endeavor of wireless communication headsets. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teachings of Lindner, as modified by Jorgovanovic, and Broadley to create the headset, further comprising at least one headband, wherein the at least one earpiece comprises a first earpiece and a second earpiece, and wherein the first earpiece and the second earpiece are interconnected through the at least one headband. The motivation to combine both references would come from the need to have a means of supporting and coupling the left and right earpieces.
