Riken has 33 pending office actions in Biotechnology & Pharmaceuticals. Each matter is assigned to a distinct examiner, while the portfolio spans 28 distinct art units, indicating broad technical and examiner distribution.
KIM, ANDREW SANG is the busiest identified examiner, with 1 pending matter. The absence of repeated examiner assignments supports individualized prosecution planning, with centralized coordination focused on consistent treatment of portfolio-wide technical themes.
Based on the USPTO statutory response window for each pending office action. 11 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. 11 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 | 3 (9%) |
| §101 + other | 6 (18%) |
| §103 only | 11 (33%) |
| §102 only | 2 (6%) |
| Multi-statute (no §101) | 11 (33%) |
