Mitsubishi Heavy Industries Aero Engines Ltd. has 6 pending office actions in Chemistry & Materials. The docket covers 5 distinct examiners and 5 distinct art units, indicating one overlap in examiner assignments or art-unit distribution while maintaining broad technical separation.
LAW, NGA LEUNG V is the busiest examiner, with 2 pending matters. That examiner is the main point of concentration in the active docket, so related response strategies may be useful for those matters while other cases require separate handling.
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.
| Bucket | Cases |
|---|---|
| §103 only | 2 (40%) |
| Multi-statute (no §101) | 3 (60%) |
