423 pending office actions • 192 art units • 393 examiners • 0 of 423 (0%) have an AI response strategy ready • 976 patents granted in the last 365 days
Mitsubishi Electric Corporation manages a large volume of 412 pending office actions, primarily in the Semiconductors, Circuits & Optics technology area. These actions are spread across 145 distinct art units, indicating a vast and complex technological footprint. The company interacts with 380 distinct examiners, which suggests a high level of variety in examiner interactions and potential prosecution outcomes.
Van Roy, Tod Thomas is the busiest examiner for the portfolio, holding 4 pending office actions. Despite the high total number of 412 actions, the work is so widely distributed that even the busiest examiner handles less than one percent of the pending load. This distribution requires the company to manage relationships and track trends across 380 different examiners simultaneously. The 145 distinct art units involved further emphasize the need for a prosecution strategy that can adapt to a wide array of technical examination standards.
Based on the USPTO statutory response window for each pending office action. 85 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. 85 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 | 24 (6%) |
| §101 + other | 72 (17%) |
| §103 only | 125 (30%) |
| §102 only | 22 (5%) |
| §112 only | 18 (4%) |
| Double-patenting + other | 2 (0%) |
| Multi-statute (no §101) | 159 (38%) |
| No statute on record | 1 (0%) |
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.
