Mitsubishi Electric Corporation has 419 pending office actions in Semiconductors, Circuits & Optics. The matters are distributed across 388 distinct examiners and 191 distinct art units, indicating a broad prosecution footprint rather than concentration in a small examination group.
VAN ROY, TOD THOMAS is the busiest identified examiner, with 4 pending matters. Counsel managing this portfolio should support consistent claim strategy and disclosure guidance across many examiner and art-unit assignments, while giving focused attention to the small cluster before this examiner.
Based on the USPTO statutory response window for each pending office action. 81 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. 81 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 | 19 (5%) |
| §101 + other | 70 (17%) |
| §103 only | 128 (31%) |
| §102 only | 24 (6%) |
| §112 only | 21 (5%) |
| Double-patenting + other | 2 (0%) |
| Multi-statute (no §101) | 149 (36%) |
| 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.
