Fuso Chemical Co. Ltd. has 2 pending office actions in Chemistry & Materials. Each matter is associated with a distinct examiner and a distinct art unit, indicating separate examination channels.
HUANG, CHENG YUAN is the busiest examiner, with 1 pending matter. Counsel should manage the matters independently and avoid assuming that one examiner’s treatment will govern the other application.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
