Cellcentric GmbH & Co. Kg has 7 pending office actions in Chemistry & Materials. The matters involve 7 distinct examiners and 5 distinct art units, indicating that prosecution is distributed across several examination assignments rather than concentrated in one unit.
VAN KIRK, DUSTIN KENWOOD is the busiest examiner, with 1 pending matter. That assignment represents a limited portion of the pending work, so counsel should track examiner-specific developments while maintaining a portfolio-level view across the other assignments.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 |
|---|---|
| §103 only | 4 (57%) |
| §112 only | 1 (14%) |
| Multi-statute (no §101) | 2 (29%) |
