Kurita Water Industries Ltd. has 15 pending office actions in Chemistry & Materials. The matters involve 15 distinct examiners and 13 distinct art units, showing extensive examiner dispersion and a smaller amount of art-unit reuse. PRESSLEY, PAUL DEREK is the busiest examiner, with 1 pending matter.
The action and examiner figures are equal, so no examiner handles multiple matters in the available data. The thirteen art units provide a useful structure for identifying technical groupings, but the broad examiner spread limits the value of a single examiner-centered strategy. Counsel should maintain individualized response histories while coordinating positions where matters share an art-unit assignment.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 (14%) |
| §103 only | 4 (29%) |
| §102 only | 3 (21%) |
| Multi-statute (no §101) | 5 (36%) |
