DEXerials Corporation has 25 pending office actions in Chemistry & Materials. The docket spans 24 distinct examiners and 21 distinct art units, indicating broad distribution with limited examiner and art-unit overlap.
SUL, STEPHEN SANGJIN is the busiest examiner, with 2 pending matters. The modest concentration supports targeted review of that examiner’s matters, but the broader docket calls for consistent portfolio positions and individualized responses across the remaining assignments.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 | 12 (46%) |
| §102 only | 4 (15%) |
| §112 only | 1 (4%) |
| Double-patenting only | 1 (4%) |
| Double-patenting + other | 1 (4%) |
| Multi-statute (no §101) | 7 (27%) |
