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) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cyzs (US 2021/0258029) in view of Backstrom et al. (NPL “Introduction to Speech Processing).
Regarding Claim 2, Cyzs teaches all of the claimed limitation recited in Claim 1. Cyzs does not teach wherein the signal windowing procedure comprises the processor extracting an end portion of the sampling window and adding the extracted end portion to a beginning portion of the sampling window, and extracting a beginning portion of the sampling window and adding the extracted beginning portion to an end portion of the sampling window.
Backstrom, which also teaches WOLA, teaches the processor extracting an end portion of the sampling window and adding the extracted end portion to a beginning portion of the sampling window, and extracting a beginning portion of the sampling window and adding the extracted beginning portion to an end portion of the sampling window (Section 3.2.1.2, extract overlapping windows of the signal, apply some processing, and reconstruct by windowing a second time and then adding overlapping segments renders a scenario of extracting an end portion of the sampling window and adding the extracted end portion to a beginning portion of the sampling window, and extracting a beginning portion of the sampling window and adding the extracted beginning portion to an end portion of the sampling window).
