Uop LLC has 52 pending office actions in Chemistry & Materials. The portfolio involves 37 examiners across 14 art units, indicating substantial prosecution volume with repeated examiner and technical assignments within the broader docket.
CHONG, JASON Y is the busiest examiner, with 4 pending matters. That examiner is a useful focal point for identifying recurring issues, but the portfolio still requires coordination across the remaining examination assignments. Counsel should organize the docket by art unit, monitor examiner-specific treatment within each group, and maintain consistent positions on recurring claim or prior-art issues. The concentration at the busiest examiner is sufficient for targeted review without replacing portfolio-wide management.
Based on the USPTO statutory response window for each pending office action. 16 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. 16 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 only | 1 (2%) |
| §103 only | 21 (40%) |
| §112 only | 1 (2%) |
| Double-patenting only | 4 (8%) |
| Double-patenting + other | 1 (2%) |
| Multi-statute (no §101) | 24 (46%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
