Ebara Corporation has 80 pending office actions in Medical Devices & Mechanical Engineering. The matters span 65 distinct examiners and 25 distinct art units, showing a substantial workload distributed across many examiners but a more focused set of art units. That structure supports art-unit-based organization while still requiring examiner-specific response planning.
CHANG, SUKWOO JAMES is the busiest examiner, with 5 pending matters. This is a meaningful concentration within the profile and provides a logical group for coordinated review. The remaining matters remain distributed among other examiners, so portfolio oversight should combine targeted examiner analysis with consistent technical positions and deadline controls across the art units.
Based on the USPTO statutory response window for each pending office action. 22 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. 22 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 | 7 (9%) |
| §103 only | 22 (29%) |
| §102 only | 6 (8%) |
| §112 only | 5 (6%) |
| Multi-statute (no §101) | 36 (47%) |
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.
