Bio-Rad Laboratories Inc. has 26 pending office actions in Biotechnology & Pharmaceuticals. The matters involve 23 distinct examiners and 16 distinct art units, showing broad examiner assignment with recurring exposure to several biotechnology examination units.
YU, TIAN NMN is the busiest examiner, with 2 pending matters. Those applications may benefit from coordinated review of examiner-specific objections and response approaches. The remaining matters require individualized prosecution planning, with cross-application consistency checks where related biotechnology disclosures or claim structures appear.
Based on the USPTO statutory response window for each pending office action. 7 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. 7 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 | 2 (8%) |
| §101 + other | 3 (12%) |
| §103 only | 4 (15%) |
| §102 only | 1 (4%) |
| §112 only | 3 (12%) |
| Double-patenting + other | 5 (19%) |
| Multi-statute (no §101) | 8 (31%) |
