97 pending office actions • 55 art units • 93 examiners • 0 of 97 (0%) have an AI response strategy ready • 288 patents granted in the last 365 days
Emerson Electric Co. manages 96 pending office actions within the Semiconductors, Circuits & Optics technology area. These actions are distributed among 92 distinct examiners, showing that almost every case is assigned to a unique individual. KNIGHT, DEREK DOUGLAS is the busiest examiner for the portfolio, with 2 pending actions.
The prosecution activity spans 43 distinct art units. This is a significant number of units for the 96 pending office actions, indicating a very wide range of technical subjects. The ratio of 92 distinct examiners to the 96 pending office actions reflects a highly decentralized prosecution environment.
With 43 distinct art units involved, the company's innovations are being evaluated by many different specialized groups at the USPTO. The busiest examiner handles only 2 pending actions, which is a minimal concentration given the 96 total pending office actions. This broad distribution across 92 distinct examiners suggests that Emerson Electric Co. must adapt to many different examination styles and technical perspectives.
Based on the USPTO statutory response window for each pending office action. 20 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. 20 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 | 2 (2%) |
| §101 + other | 11 (11%) |
| §103 only | 31 (32%) |
| §102 only | 8 (8%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 4 (4%) |
| Multi-statute (no §101) | 38 (39%) |
| No statute on record | 2 (2%) |
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.
