17 pending office actions • 8 art units • 17 examiners • 0 of 17 (0%) have an AI response strategy ready • 12 patents granted in the last 365 days
Kurita Water Industries Ltd. currently has 17 pending office actions within the Chemistry & Materials technology area. These 17 actions are distributed among 17 distinct examiners, which means every pending matter is being handled by a different individual. This broad examiner base is spread across 8 distinct art units, indicating technical and administrative variety within the USPTO. Such a wide distribution suggests that the portfolio covers a diverse range of chemical processes and material sciences.
PAUL DEREK PRESSLEY is the busiest examiner, responsible for 1 busiest examiner pending action. Because each of the 17 distinct examiners is assigned exactly 1 of the 17 pending office actions, the workload is entirely decentralized. Navigating 8 distinct art units requires the company to manage various procedural nuances and potentially different examination speeds. With 17 pending office actions and 17 distinct examiners, the company cannot rely on 1 relationship to move the portfolio forward. Instead, it must maintain 17 independent prosecution strategies tailored to the specific requirements of each examiner. This level of dispersion across 8 distinct art units may increase the complexity of maintaining a unified legal strategy.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 | 1 (6%) |
| §103 only | 6 (35%) |
| §102 only | 3 (18%) |
| Multi-statute (no §101) | 7 (41%) |
