Consider claim 13, the limitations of claim 13 are not given patentable weight because “preset rule” recited in claim 12 was not given patentable weight.
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) 3-4, 11, and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sahara US 2009/0316812 in view of Si et al. US 2018/0123849.
Consider claim 3, Sahara discloses wherein the second bit sequence is a bit sequence generated by performing data encoding on a third bit sequence (see FIG. 1 and ¶ [0055], wherein the modulated bit sequence i.e. second bit sequence, is generated by performing data encoding on the transmission data output from physical layer frame generation unit 26), and the third bit sequence is determined based on the first bit sequence and the original bit sequence (see FIG. 1 and 3, wherein the output of the encoding/modulation unit 27 i.e. third bit sequence, is determined based on the physical layer header i.e. first bit sequence, and the data section i.e. original bit sequence); wherein the third bit sequence comprises the original bit sequence and the first bit sequence, and the first bit sequence is located in front of the original bit sequence (see FIG. 3).
However Sahara does not explicitly disclose baseband data encoding. Si teaches baseband data encoding (see FIG. 2 and ¶ [0064], wherein the TX processing circuitry 215 encodes, the outgoing baseband data to generate processed baseband). Si further discloses providing a synchronization signal design in an advanced wireless communication system (see ¶ [0004]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to modify the invention of Sahara, and to include baseband data encoding, as taught by Si for the purpose of providing a synchronization signal design in an advanced wireless communication system.
Consider claim 4, Sahara discloses wherein the second bit sequence comprises a sixth bit sequence and a seventh bit sequence (see FIG. 3), the sixth bit sequence is a bit sequence obtained by performing baseband data encoding on the original bit sequence (see FIG. 1 and 3, ¶ [0055]), the seventh bit sequence is a bit sequence added in front of the sixth bit sequence, and the seventh bit sequence is determined based on the first bit sequence (see FIG. 3).
Consider claims 11 and 19, Si discloses wherein the first signal is generated through on-off keying (OOK) modulation (see ¶ [0217]).
Claim(s) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sahara US 2009/0316812 in view of Si et al. US 2018/0123849 as applied to claim 4 above, and further in view of Hua et al. US 2024/0340210.
Consider claim 5, Sahara in view of Si discloses every claimed limitation in claim 4.
Sahara further discloses wherein the seventh bit sequence is the first bit sequence (see FIG. 3).
However Sahara in view of Si does not explicitly disclose wherein a baseband data encoding scheme corresponding to the first bit sequence is different from a baseband data encoding scheme corresponding to the original bit sequence. Hua teaches wherein a baseband data encoding scheme corresponding to the first bit sequence is different from a baseband data encoding scheme corresponding to the original bit sequence (see FIG. 2 and ¶ [0051], wherein the header of the OFDM signal is using π/2 BPSK modulation and coding scheme and the data information is using 16-QAM modulation and coding scheme). Hua further discloses achieving a modulation scheme with which relatively high spectral efficiency, a relatively low peak-to-average power ratio, and phase noise compensation (see ¶ [0002]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to modify the invention of Sahara in view of Si, and to include wherein a baseband data encoding scheme corresponding to the first bit sequence is different from a baseband data encoding scheme corresponding to the original bit sequence, as taught by Hua for the purpose of achieving a modulation scheme with which relatively high spectral efficiency, a relatively low peak-to-average power ratio, and phase noise compensation.
Claim(s) 6-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sahara US 2009/0316812 as applied to claims 1 and 14 above, and further in view of Hua et al. US 2024/0340210.
Consider claim 6, Sahara discloses every claimed limitation in claim 1.
Sahara further discloses wherein the symbol sequence corresponding to the original bit sequence is a first symbol sequence, the symbol sequence corresponding to the first bit sequence is a second symbol sequence (see FIG. 3 and ¶ [0033-0034]).
However Sahara does not explicitly disclose the first symbol sequence and the second symbol sequence are generated based on different modulation processes. Hua teaches the first symbol sequence and the second symbol sequence are generated based on different modulation processes (see FIG. 2 and ¶ [0051], wherein the header of the OFDM signal is using π/2 BPSK modulation and coding scheme and the data information is using 16-QAM modulation and coding scheme). Hua further discloses achieving a modulation scheme with which relatively high spectral efficiency, a relatively low peak-to-average power ratio, and phase noise compensation (see ¶ [0002]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to modify the invention of Sahara, and to include the first symbol sequence and the second symbol sequence are generated based on different modulation processes, as taught by Hua for the purpose of achieving a modulation scheme with which relatively high spectral efficiency, a relatively low peak-to-average power ratio, and phase noise compensation.

Claim 16 is rejected on the same ground as for claim 6 because of similar scope.
Claim(s) 8 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sahara US 2009/0316812 as applied to claims 1 and 14 above, and further in view of Huang et al. US 2024/0259240.
Consider claim 8, Sahara discloses every claimed limitation in claim 1.
However Sahara does not explicitly disclose wherein the first signal is a signal used for backscatter communication. Huang teaches wherein the first signal is a signal used for backscatter communication (see ¶ [0039]). Huang further discloses modulation information bits method (see ¶ [0002]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to modify the invention of Sahara, and to include wherein the first signal is a signal used for backscatter communication, as taught by Huang for the purpose of modulation information bits method.
Claim 17 is rejected on the same ground as for claim 8 because of similar scope.
