Covestro AG currently manages 43 pending office actions within the Chemistry & Materials technology area. These actions are distributed among 36 distinct examiners and 17 distinct art units. This shows that while most examiners handle only a case, there is some concentration of work within the 43 pending actions, reflecting a variety of chemical and material specializations across the portfolio.
LEONARD, MICHAEL L is the busiest examiner, managing 3 pending office actions. With 36 distinct examiners involved, the majority of examiners are handling a single matter. The 17 distinct art units reflect a variety of chemical and material specializations, requiring a prosecution strategy that can adapt to different standards. Practitioners should monitor the 3 pending office actions with LEONARD, MICHAEL L while also accounting for the 17 distinct art units involved in the portfolio to identify potential group-level trends.
Based on the USPTO statutory response window for each pending office action. 9 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. 9 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 + other | 1 (2%) |
| §103 only | 20 (45%) |
| §102 only | 1 (2%) |
| §112 only | 1 (2%) |
| Double-patenting only | 1 (2%) |
| Double-patenting + other | 1 (2%) |
| Multi-statute (no §101) | 19 (43%) |
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.
