Mtu Aero Engines AG is managing 11 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed among 11 distinct examiners, meaning each examiner is responsible for a pending matter. GMOSER, WILLIAM L is the busiest examiner, holding 1 pending office action.
The 11 pending office actions are spread across 7 distinct art units. This indicates that while the examiners are entirely distinct, there is some technical concentration within the 7 art units. Because there are 11 distinct examiners for the actions, the company faces a variety of individual examiner styles. GMOSER, WILLIAM L manages 1 of the total pending actions, showing that no single examiner has a dominant influence over the current prosecution of the portfolio.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 (9%) |
| §103 only | 3 (27%) |
| §102 only | 1 (9%) |
| Multi-statute (no §101) | 6 (55%) |
How the docket's pending cases split across USPTO tech-center bands.
