Fuji Electric Co., Ltd. has 103 pending office actions in Semiconductors, Circuits & Optics. The portfolio spans 89 distinct examiners and 31 distinct art units, creating a broad examination footprint with multiple technical groupings.
LEE, JYE-JUNE is the busiest examiner, with 3 pending matters. The assignment is a small segment of the stated workload. Counsel should preserve centralized oversight while tracking art-unit developments and examiner-specific response patterns across the portfolio.
Based on the USPTO statutory response window for each pending office action. 17 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. 17 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 | 1 (1%) |
| §101 + other | 3 (3%) |
| §103 only | 40 (40%) |
| §102 only | 10 (10%) |
| §112 only | 5 (5%) |
| Multi-statute (no §101) | 42 (42%) |
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.
