25 pending office actions • 14 art units • 22 examiners • 0 of 25 (0%) have an AI response strategy ready • 27 patents granted in the last 365 days
Versum Materials US LLC is managing 25 pending office actions within the Chemistry & Materials technology area. These actions are assigned to 22 distinct examiners. The portfolio is distributed across 14 distinct art units, indicating that the company's chemical innovations fall into several different technical classifications. With 14 distinct art units involved, the prosecution strategy must address the specific requirements and trends of many different specialized groups within the patent office while managing the 25 pending office actions.
The busiest examiner is DEO, DUY VU NGUYEN, who is overseeing 3 pending office actions. The remaining actions are spread across the other 22 distinct examiners. This means that 22 distinct examiners are providing feedback on the company's applications. The breadth of 14 distinct art units suggests that the company's materials research is technically diverse, requiring the prosecution team to navigate the unique examination cultures of many different specialized units. Having 3 pending office actions assigned to DEO, DUY VU NGUYEN represents the most concentrated point of contact in the portfolio.
Based on the USPTO statutory response window for each pending office action. 9 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. 9 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 + other | 1 (4%) |
| §103 only | 10 (40%) |
| §102 only | 2 (8%) |
| §112 only | 2 (8%) |
| Multi-statute (no §101) | 8 (32%) |
| No statute on record | 2 (8%) |
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.
