Roquette Freres has 23 pending office actions in Chemistry & Materials. The docket involves 19 distinct examiners across 12 distinct art units, indicating both repeated examiner assignments and broader sharing within art units. This structure supports portfolio review organized around technical groupings, while preserving examiner-specific prosecution analysis.
LI, CHANGQING is the busiest examiner, with 2 pending matters. That is the largest stated examiner assignment, so those matters may warrant a coordinated review for common issues before separate responses are prepared.
Based on the USPTO statutory response window for each pending office action. 11 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. 11 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 | 2 (8%) |
| §103 only | 9 (38%) |
| §112 only | 2 (8%) |
| Double-patenting + other | 3 (12%) |
| Multi-statute (no §101) | 7 (29%) |
| No statute on record | 1 (4%) |
How the docket's pending cases split across USPTO tech-center bands.
