Osstem Implant Co. Ltd. has 5 pending office actions in Medical Devices & Mechanical Engineering. The matters are handled by 5 distinct examiners across 3 distinct art units, showing examiner-level dispersion with some art-unit overlap.
LUCCHESI, NICHOLAS D is the busiest examiner, with 1 pending matter. The absence of a larger examiner concentration favors individualized responses, while the shared art-unit structure may still support comparison of claim construction and recurring procedural requirements.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 + other | 2 (40%) |
| §103 only | 1 (20%) |
| Multi-statute (no §101) | 2 (40%) |
