Calb Group Co. Ltd. has 4 pending office actions in Chemistry & Materials. The matters involve 4 distinct examiners across 3 distinct art units, indicating full examiner dispersion with some grouping at the art-unit level.
BROWN, MADISON ELIZABETH is the busiest examiner, with 1 pending matter. Counsel should manage each action separately while comparing the three art-unit assignments for consistent treatment of related materials or chemical claim issues.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
