47 pending office actions • 21 art units • 43 examiners • 0 of 47 (0%) have an AI response strategy ready • 79 patents granted in the last 365 days
Fresenius SE & Co. KGaA manages a substantial portfolio with 46 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 42 distinct examiners, indicating a high level of diversification in the prosecution process. The workload is further spread across 21 distinct art units, which demonstrates the broad technical scope of the company's medical and mechanical innovations.
The busiest examiner, PEO, JONATHAN M, is responsible for 3 busiest examiner pending actions. This relatively low number of actions per examiner, even for the busiest individual, suggests that no single examiner has an outsized influence on the 46 pending office actions. The presence of 42 distinct examiners means that most examiners are handling only one matter for the company. Navigating 21 distinct art units requires a versatile prosecution strategy to address the varying standards and practices across a large portion of the patent office.
Based on the USPTO statutory response window for each pending office action. 13 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. 13 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 | 2 (4%) |
| §101 + other | 5 (11%) |
| §103 only | 11 (23%) |
| §102 only | 1 (2%) |
| §112 only | 1 (2%) |
| Double-patenting only | 1 (2%) |
| Double-patenting + other | 4 (9%) |
| Multi-statute (no §101) | 22 (47%) |
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.
