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 nonobviousness.
Claim(s) 2 and 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Braun et al. (EP 3,958,013 A2, cited by applicant in IDS dated 3 MAR 2025) in view of Mattheijssen et al. (US 2021/0359739 A1, cited by applicant in IDS dated 3 MAR 2025).
Regarding claim 2, Braun et al. discloses:
[Note: what is not explicitly taught by Braun et al. has been struck-through]
The wireless communication and sensing method of claim 1, wherein a communication signal of the ISAC signal is sent and received by the one or more communication antennas (Braun et al. “As illustrated in Fig. 10, a first antenna array may be used for transmission 1010 of data and the radar excitation signals, as well as reception 1011 of data, all with full array gain.” - ¶ [0077]) and a sensing signal of the ISAC signal is received by the one or more communication antennas (Braun et al. “The second antenna array may further be applied, for example, in the uplink time interval, for receiving data and/or control information from the UEs to enhance data rate and/or reliability.” - ¶ [0077])
Mattheijssen et al. discloses:
a sensing signal of the ISAC signal is transmitted by the one or more sensing-dedicated antennas (Mattheijssen et al. combined radar comes mode of configurable antenna system 430 comprises radar transmitting antenna 420c, Fig. 14G).
It would have been obvious to someone with ordinary skill in the art prior to the effective filing date of the claimed invention to incorporate the features as disclosed by Mattheijssen et al. into the invention of Braun et al. to yield the invention of claim 2 above. Both Braun et al. and Mattheijssen et al. are considered analogous arts to the claimed invention as they both disclose integrated communication and sensing methods for wireless communication and sensing. Braun et al. discloses a first antenna array that transmits data and radar signals, and a second antenna array for receiving the data or radar signals (Braun et al. ¶ [0077]). However, Braun et al. fails to explicitly disclose a sensing signal of the ISAC signal is transmitted by the one or more sensing-dedicated antennas. This feature is disclosed by Mattheijssen et al. where the reconfigurable antenna system comprises a mode with a sensing-dedicated antenna for transmitting a sensing signal (Mattheijssen et al. radar transmitting antenna 420c, Fig. 14G). The combination of Braun et al. and Mattheijssen et al. would be obvious with a reasonable expectation of success to implement a reconfigurable antenna system in order to “optimize the highest data throughput at the lowest usage of electrical power” (Mattheijssen et al. ¶ [0071]).
Regarding claim 10, Braun et al. discloses:
[Note: what is not explicitly taught by Braun et al. has been struck-through]

wherein the one or more communication antennas are configured to send and receive a communication signal of the ISAC signal (Braun et al. “As illustrated in Fig. 10, a first antenna array may be used for transmission 1010 of data and the radar excitation signals, as well as reception 1011 of data, all with full array gain.” - ¶ [0077])
Mattheijssen et al. discloses:
the one or more sensing-dedicated antennas are configured to transmit a sensing signal of the ISAC signal (Mattheijssen et al. combined radar comes mode of configurable antenna system 430 comprises radar transmitting antenna 420c, Fig. 14G)
It would have been obvious to someone with ordinary skill in the art prior to the effective filing date of the claimed invention to incorporate the features as disclosed by Mattheijssen et al. into the invention of Braun et al. to yield the invention of claim 10 above. Both Braun et al. and Mattheijssen et al. are considered analogous arts to the claimed invention as they both disclose integrated communication and sensing methods for wireless communication and sensing. Braun et al. discloses a first antenna array that transmits data and radar signals, and a second antenna array for receiving the data or radar signals (Braun et al. ¶ [0077]). However, Braun et al. fails to explicitly disclose a sensing signal of the ISAC signal is transmitted by the one or more sensing-dedicated antennas. This feature is disclosed by Mattheijssen et al. where the reconfigurable antenna system comprises a mode with a sensing-dedicated antenna for transmitting a sensing signal (Mattheijssen et al. radar transmitting antenna 420c, Fig. 14G). The combination of Braun et al. and Mattheijssen et al. would be obvious with a reasonable expectation of success to implement a reconfigurable antenna system in order to “optimize the highest data throughput at the lowest usage of electrical power” (Mattheijssen et al. ¶ [0071]).
Claim(s) 16-19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Braun et al. (EP 3,958,013 A2, cited by applicant in IDS dated 3 MAR 2025) in view of Jeon et al. (US 2022/0256519 A1).
Regarding claim 16, Braun et al. discloses:

receiving an echo signal associated with the sensing signal of the ISAC signal via a second group of antenna[s] (Braun et al. “A second antenna array may be used for receiving 102 the reflected radar signals with full array gain for the radar processing.” - ¶ [0077]), wherein the first group of antenna[s] (Braun et al. the second array of antennas is different from the first array of antennas, Fig. 10).
Jeon et al. discloses:
transmitting a sensing signal of an integrated sensing and communication (ISAC) signal via a first group of antenna ports (Jeon et al. “a first set of symbols/slots/subframes/frames in the time pattern are configured for radar sensing…” - ¶ [0412]; “a set of resources/symbols/slots/subframes for radar can be further split between radar transmission (radar Tx) and radar reception (radar Rx)” - ¶ [0413]; “An antenna port is defined such that the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed.” - ¶ [0226]; where the subset for radar transmission is the first group of antenna ports), and
receiving an echo signal associated with the sensing signal of the ISAC signal via a second group of antenna ports, wherein the first group of antenna ports are different from the second group of antenna ports (Jeon et al. “a set of resources/symbols/slots/subframes for radar can be further split between radar transmission (radar Tx) and radar reception (radar Rx)… In one example, time-domain resources are configured only for radar Tx but not for radar Rx (or only for radar Rx, but not for radar Tx).” - ¶ [0413]; “An antenna port is defined such that the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed.” - ¶ [0226]; where the subset for radar reception is the second group of antenna ports).
It would have been obvious to someone with ordinary skill in the art prior to the effective filing date of the claimed invention to incorporate the features as disclosed by Jeon et al. into the invention of Braun et al. to yield the invention of claim 16 above. Both Braun et al. and Jeon et al. are considered analogous arts to the claimed invention as they both disclose integrated communication and sensing methods for wireless communication and sensing. Braun et al. discloses the limitations of claim 16 outlined above, where the integrated communication and sensing method uses groups of antennas. However, Braun et al. fails to explicitly disclose using groups of antenna ports. This feature is disclosed by Jeon et al. where a first set of resources is configured for radar sensing, and the first set of resources can be further split into subsets for radar transmission and radar reception (Jeon et al. ¶ [0412]-[0413]. The combination of Braun et al. and Jeon et al. would be obvious with a reasonable expectation of success to “reduce/eliminate intra-UE interference, and accommodate high quality (such as high-SINR) reception of channels and signals for both DL/UL/SL communications and radar sensing, which increases the performance of both operations” (Jeon et al. ¶ [0210]).

It would have been obvious to someone with ordinary skill in the art prior to the effective filing date of the claimed invention to incorporate the features as disclosed by Jeon et al. into the invention of Braun et al. as modified above to yield the invention of claim 17. Both Braun et al. and Jeon et al. are considered analogous arts to the claimed invention as they both disclose integrated communication and sensing methods for wireless communication and sensing.
