ChampionX LLC has 25 pending office actions in Chemistry & Materials. The matters are distributed across 18 distinct examiners and 14 distinct art units, indicating some recurrence at both the examiner and technical-group levels. This structure creates a basis for identifying shared prosecution issues while preserving flexibility for different examination paths.
LI, AIQUN is the busiest examiner, with 4 pending matters. The assignment is a useful focal point for reviewing examiner-specific treatment and response history. It does not eliminate the need for broader coordination, because the remainder of the docket is spread across multiple examiners and art units.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 | 8 (33%) |
| §102 only | 1 (4%) |
| §112 only | 1 (4%) |
| Double-patenting + other | 2 (8%) |
| Multi-statute (no §101) | 12 (50%) |
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.
