PFU Limited has 16 pending office actions in Communications. Those matters involve 13 distinct examiners across 8 distinct art units, indicating that the portfolio spans multiple examination assignments rather than concentrating in one unit.
DICKERSON, CHAD S is the busiest examiner, with 2 pending matters. Prosecution management should therefore track both examiner-specific issues and the broader distribution across art units, since the largest examiner grouping represents only part of the portfolio.
Based on the USPTO statutory response window for each pending office action. 8 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. 8 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 | 9 (53%) |
| §102 only | 2 (12%) |
| Double-patenting only | 1 (6%) |
| Multi-statute (no §101) | 5 (29%) |
