ChampionX LLC has 14 pending office actions in the Chemistry & Materials technology area. These actions are distributed across 12 distinct examiners and 8 distinct art units. RUNYAN, SILVANA C is the busiest examiner, currently managing 2 pending office actions. The 14 pending actions are spread across 8 distinct art units, suggesting a variety of technical focuses within the chemistry and materials field.
With 12 distinct examiners involved, the company interacts with multiple officials, though RUNYAN, SILVANA C handles 2 of the 14 total actions. This distribution provides a balanced prosecution environment across multiple examiners and art units. The busiest examiner pending count of 2 is a portion of the 14 total pending actions. The involvement of 8 distinct art units shows that the company's technology is being evaluated by different technical sections of the patent office. RUNYAN, SILVANA C is the busiest examiner for these 14 pending office actions. This structure indicates that the workload is distributed across 12 distinct examiners rather than being concentrated under one individual.
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 | 7 (35%) |
| §112 only | 1 (5%) |
| Double-patenting + other | 2 (10%) |
| Multi-statute (no §101) | 10 (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.
