77 pending office actions • 40 art units • 62 examiners • 0 of 77 (0%) have an AI response strategy ready • 63 patents granted in the last 365 days
Entegris Inc. operates within the Chemistry & Materials technology area with a total of 77 pending office actions. These 77 pending office actions are distributed across 40 distinct art units. This distribution shows that the number of pending actions is higher than the number of 40 distinct art units involved in the prosecution process. The company interacts with 62 distinct examiners to manage these filings.
The busiest examiner identified in the data is MENON, KRISHNAN S, who is currently handling 6 busiest examiner pending office actions. These 6 busiest examiner pending office actions are a subset of the total pending office actions currently active for the company. The 62 distinct examiners assigned to the portfolio are more numerous than the 40 distinct art units where the cases are being reviewed. This indicates that many art units contain multiple examiners working on the company's matters.
Practitioners should note that MENON, KRISHNAN S manages 6 busiest examiner pending office actions, while the other actions are spread among the other distinct examiners. The Chemistry & Materials technology area serves as the primary classification for this work. With 62 distinct examiners, the portfolio shows engagement with the patent office staff across the various art units identified in the data.
Based on the USPTO statutory response window for each pending office action. 24 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. 24 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 (1%) |
| §103 only | 27 (35%) |
| §102 only | 4 (5%) |
| §112 only | 2 (3%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 3 (4%) |
| Multi-statute (no §101) | 39 (51%) |
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.
