Covestro AG has 41 pending office actions in Chemistry & Materials. These matters involve 33 distinct examiners across 20 distinct art units, reflecting a broad prosecution program with recurring technical examination environments. The distribution favors coordination by art unit and subject matter rather than reliance on a single examiner relationship.
LEONARD, MICHAEL L is the busiest examiner, with 3 pending matters. The concentration warrants review of that examiner's positions for consistency, while the wider assignment pattern calls for separate analysis of the remaining applications.
Based on the USPTO statutory response window for each pending office action. 10 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 10 of the docket's apps have a known mailing date.
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 |
|---|---|
| §101 only | 1 (2%) |
| §101 + other | 1 (2%) |
| §103 only | 18 (44%) |
| §112 only | 1 (2%) |
| Double-patenting + other | 1 (2%) |
| Multi-statute (no §101) | 19 (46%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
