Claim Rejections - 35 USC § 102
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.

Regarding claim 1, Oswald anticipates:
“A system, comprising:
a first set of near-field (NF) speakers” by teaching a binaural device with speakers disposed in a headrest (see Oswald, ¶ 0043 and 0074, figures 1A and 5, units 110, 118L, and 118R);
“a set of sensors for detecting at least one of a position or an orientation of a first user in a first listening location” by teaching headtracking devices, such as multiple 2D cameras or a combination of various sensors (see Oswald, ¶ 0075 and 0087, and figure 5, units 506 and 508); and
“a controller coupled with the first set of NF speakers and the set of sensors” by teaching a controller that receives the outputs from the headtracking devices and generates a binaural signal for the first set of NF speakers (see Oswald, ¶ 0077-0078 and figure 5, units 504, 506, 110, and b1),
“and configured to:
adjust an audio output at the first set of NF speakers, wherein the controller is configured to maintain spatialization of the audio output to the first user based on detecting at least one of a position change or an orientation change of the first user” by teaching that the controller generates a binaural signal based on the position signal received from the headtracking device, where the binaural signal uses a plurality of head-related transfer functions (HRTFs) to adjust the binaural signal for a listener to perceive a sound emanating from a specific virtual spatial point (see Oswald, ¶ 0077-0079 and figure 5, units 504, 506, 110, 114L-114R, h1, e1, b1, and SP1), and
“wherein the controller is configured to control the spatialized audio output to the first user with the first set of NF speakers with consideration of isolation to a second listening location” by teaching that the first listening position receives different audio from a second listening position and that the two or more listening positions are isolated such that the listening positions hear different spatialized audio (see Oswald, ¶ 0035, 0037, 0061, 0064-0065, 0067, and 0074, figures 1A and 5, units P1 and P2).
Regarding claim 2, see the preceding rejection with respect to claim 1 above.

Claim Rejections - 35 USC § 103
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
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.
Claim(s) 6, 31, and 46 is/are rejected under 35 U.S.C. 103 as being unpatentable over Oswald as applied to claims 1, 26, and 45 above, and further in view of Cai et al. (US 2022/0353614 A1, previously cited and hereafter Cai).
Regarding claim 6, see the preceding rejection with respect to claim 1 above. Oswald anticipates the “system of claim 1, wherein the audio output is approximately consistently isolated during the position and/or orientation change of the first user” by teaching that the upper frequency range is isolated from changing position and orientation change of the first user through the use of the near-field speakers and the headtracking system (see Oswald, ¶ 0035, 0037, 0043, 0061, and 0077-0079, and figure 5, units 504, 506, 110, and 118L-118R).
Oswald also teaches that the lower frequency range is isolated by at least 3 dB between listening positions using the perimeter speakers of the vehicle (see Oswald, ¶ 0038-0040 and figure 5, units 102, P1, and P2). However, Oswald does not clearly teach the isolation “by 5 decibels (dB) or more across the listening bandwidth during the position and/or orientation change of the first user”.
Cai teaches a loudspeaker system layout for generating low frequency audio outputs in individual sound zones (see Cai, abstract). Herein, Cai teaches cross talk cancellation to deliver full-bandwidth separation in acoustic responses between different zones in a vehicle cabin (see Cai, ¶ 0023), and/or teaches placing multiple proximity woofers closer to each listening zone (see Cai, ¶ 0029, figures 2-3, ¶ 0036-0037, and figures 8-9B). It would have been obvious to one of ordinary skill in the art at the time of the effective filing date to modify Oswald with the teachings of Cai for the purpose of improving the acoustic isolation across the listening, or full, bandwidth (see Oswald, ¶ 0038-0040 in view of Cai, ¶ 0023, 0038, 0041, 0043, and figures 10-12).
Therefore, the combination of Oswald and Cai makes obvious the “system of claim 1, wherein the audio output is approximately consistently isolated during the position and/or orientation change of the first user, wherein the consistently isolated audio output is characterized by a difference in perception of the audio output at the second listening location, relative to a perception of the audio output at the first listening location, by 5 decibels (dB) or more across the listening bandwidth during the position and/or orientation change of the first user” by making it obvious to use crosstalk cancellation for the low frequency and high frequency bands to isolate the audio output based on the user’s position and/or orientation changing during output (see Oswald, ¶ 0035, 0037, 0043, 0061, and 0077-0079, and figure 5, units 504, 506, 110, and 118L-118R, where the upper frequency range is isolated from changing position and orientation change of the first user through the use of the near-field speakers, the headtracking system, and crosstalk cancellation, and see Cai, ¶ 0023, 0029, 0038, 0041, and 0043 figures 2-3 and 10-12).
Regarding claim 31, see the preceding rejection with respect to claims 6 and 26 above. Oswald anticipates the “vehicle audio system of claim 26”, and for the same reasons as stated above with respect to claim 6, the combination of Oswald and Cai makes obvious:
“The vehicle audio system of claim 26, wherein the audio output is approximately consistently isolated during the position and/or orientation change of the first user, wherein the consistently isolated audio output is characterized by a difference in perception of the audio output at the second listening location, relative to a perception of the audio output at the first listening location, by 5 decibels (dB) or more across the listening bandwidth during the position and/or orientation change of the first user” by making it obvious to use crosstalk cancellation for the low frequency and high frequency bands to isolate the audio output based on the user’s position and/or orientation changing during output (see Oswald, ¶ 0035, 0037, 0043, 0061, and 0077-0079, and figure 5, units 504, 506, 110, and 118L-118R, where the upper frequency range is isolated from changing position and orientation change of the first user through the use of the near-field speakers, the headtracking system, and crosstalk cancellation, and see Cai, ¶ 0023, 0029, 0038, 0041, and 0043 figures 2-3 and 10-12).
Regarding claim 46, see the preceding rejection with respect to claims 6 and 45 above. Oswald anticipates the “audio system of claim 45”, and for the same reasons as stated above with respect to claim 6, the combination of Oswald and Cai makes obvious:
“The audio system of claim 45, wherein the consistently isolated audio output is characterized by a difference in perception of the audio output at the second listening location, relative to a perception of the audio output at the first listening location, by 5 decibels (dB) or more across the listening bandwidth during the position and/or orientation change of the user in the first listening location” by making it obvious to use crosstalk cancellation for the low frequency and high frequency bands to isolate the audio output based on the user’s position and/or orientation changing during output (see Oswald, ¶ 0035, 0037, 0043, 0061, and 0077-0079, and figure 5, units 504, 506, 110, and 118L-118R, where the upper frequency range is isolated from changing position and orientation change of the first user through the use of the near-field speakers, the headtracking system, and crosstalk cancellation, and see Cai, ¶ 0023, 0029, 0038, 0041, and 0043 figures 2-3 and 10-12), and
“wherein the controller is configured to maintain spatialization of the audio output based on detecting at least one of a position change or an orientation change of the user in the first listening location” by teaching that the upper frequency range is isolated from changing position and orientation change of the first user through the use of the near-field speakers and the headtracking system (see Oswald, ¶ 0035, 0037, 0043, 0061, and 0077-0079, and figure 5, units 504, 506, 110, and 118L-118R, and see Cai, ¶ 0023 and 0029 and figures 2-3).
Claim(s) 12 and 36 is/are rejected under 35 U.S.C. 103 as being unpatentable over Oswald as applied to claims 1 and 26 above.
Regarding claim 12, see the preceding rejection with respect to claim 1 above. Oswald anticipates the “system of claim 1, wherein the position and/or orientation change of the first user includes at least one of: head movement or rotation, body movement, or seat movement …” because Oswald teaches the headtracking device is used to update azimuth angles for selecting appropriate HRTFs for localizing the virtual sound points (see Oswald, ¶ 0079-0080).
Oswald makes obvious the additional features “wherein the controller maintains the spatialization of the audio output while the head rotation of the first user deviates from center by up to approximately 40 degrees”, Oswald makes obvious this feature because the first user is sitting in a driver’s seat within a vehicle, such that it is obvious that the first user will be using the system while turning their head to look left and right when operating the vehicle.
Regarding claim 36, see the preceding rejection with respect to claim 26 above. Oswald anticipates the “vehicle audio system of claim 26, wherein a set of additional speakers outside of the near field provide a low frequency portion of the audio output, wherein the position and/or orientation change of the first user includes at least one of: head movement or rotation, body movement, or seat movement, and wherein the controller maintains the spatialization of the audio output while the head rotation of the first user deviates from center by up to approximately 40 degrees” because Oswald teaches the headtracking device is used to update azimuth angles for selecting appropriate HRTFs for localizing the virtual sound points (see Oswald, ¶ 0079-0080), and makes obvious this feature because the first user is sitting in a driver’s seat within a vehicle, such that it is obvious that the first user will be using the system while turning their head to look left and right when operating the vehicle.
Allowable Subject Matter
Claims 21 and 43 are 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.
