Doosan Corporation has 3 pending office actions in Chemistry & Materials. The matters are distributed among 3 distinct examiners and 3 distinct art units, showing separate examination contexts across the docket.
HEINCER, LIAM J is the busiest examiner, with 1 pending matter. Counsel should evaluate each matter independently and avoid assuming that one art-unit practice will govern the full portfolio.
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.
