Rockwool A/S manages 15 pending office actions within the Chemistry & Materials technology area. The portfolio is distributed across 10 distinct art units and 13 distinct examiners, showing a high degree of variety for its size. This distribution suggests that the company's patent applications touch on several different chemical or material science disciplines within the USPTO. With 13 distinct examiners involved, the prosecution team must adapt to many different individual styles and requirements.
The busiest examiner, HERRING, LISA L, is assigned to 3 pending office actions. This examiner handles a larger share of the portfolio than the other examiners, as the total number of actions is 15. With 10 distinct art units involved, the prosecution team must be prepared for a wide range of procedural nuances, as the portfolio is not heavily concentrated in any single administrative group. This diversity across 10 distinct art units indicates a broad technical range for the pending applications.
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 |
|---|---|
| §103 only | 4 (27%) |
| §112 only | 1 (7%) |
| Double-patenting only | 1 (7%) |
| Double-patenting + other | 2 (13%) |
| Multi-statute (no §101) | 7 (47%) |
