9 pending office actions • 6 art units • 9 examiners • 0 of 9 (0%) have an AI response strategy ready • 8 patents granted in the last 365 days
Reinz-Dichtungs-Gmbh maintains 9 pending office actions in the Chemistry & Materials technology area. These actions are distributed across 9 distinct examiners, showing that no single individual handles a majority of the current workload. This distribution suggests a broad engagement with the patent office staff rather than a concentrated relationship with a few specific examiners. Practitioners should prepare for varied examiner styles across the portfolio.
The portfolio spans 6 distinct art units, which reflects a diverse range of technical subject matter within the materials sector. FORRY, COLTON BUSA is identified as the busiest examiner, though they are currently managing only 1 pending office action. This parity between the total number of examiners and the total number of pending actions indicates that each examiner is handling a single case for the company. Such a spread requires monitoring multiple prosecution timelines simultaneously across different administrative units.
Based on the USPTO statutory response window for each pending office action. 2 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 (22%) |
| Multi-statute (no §101) | 7 (78%) |
How the docket's pending cases split across USPTO tech-center bands.
