Claim Rejections - 35 USC § 103
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.
Claims 3-4 and 8-9 are rejected under 35 U.S.C. 103 as being unpatentable over Chung et al. (US 2019/0312892 hereinafter Chung) in view of Sasaki et al. (US 2014/0047255 hereinafter Sasaki).
Regarding claim 3, Chung discloses the intrusion detection device according to claim 1.
Chung does not explicitly disclose further comprising a status determination unit that determines whether or not the in-vehicle electronic devices belonging to the same group have the same communication control status, wherein the abnormality detection unit detects an abnormality on the basis of a determination result of the status determination unit.
However, Sasaki discloses a status determination unit that determines whether or not the in-vehicle electronic devices belonging to the same group have the same communication control status, wherein the abnormality detection unit detects an abnormality on the basis of a determination result of the status determination unit (FIG. 7 & 10, ¶ [0083]-[0086], [0102]).
Therefore, it would have been obvious to one of ordinary skill in the art before effective filing date of the claimed invention to combine Chung and Sasaki in order to efficiently detect malfunction or abnormality in the vehicular network management (Sasaki, ¶ [0005]-[0012]).
