Supreme Court dismissed extraordinary review for procedural errors not constituting invalid proceedings.

The Supreme Court dismissed the extraordinary review filed by the Patent Office against the Appeals Commission's decision to reject a patent invalidation request. The Patent Office argued that the Appeals Commission improperly relied on an expert opinion regarding the utility of a mining support design, claiming this constituted a material law violation. However, the Court determined that the arguments focused on evidentiary assessment rather than a direct misinterpretation of the substantive law or an invalid procedure. Consequently, the review was rejected because the alleged procedural defects did not meet the strict criteria for extraordinary review under the Civil Procedure Code.
