Technology area: Biotechnology & Pharmaceuticals
48 pending office actions • 27 art units • 48 examiners • 2 of 48 (4%) have an AI response strategy ready • 12 patents granted in the last 365 days
Otsuka Pharmaceutical Co., Ltd. is currently managing 48 pending office actions within the Biotechnology & Pharmaceuticals technology area. This portfolio is exceptionally broad, as evidenced by the 27 distinct art units involved in the examination process. The prosecution of these 48 actions is distributed among 48 distinct examiners, meaning that every single pending matter is being reviewed by a different individual.
The busiest examiner, KUCHARCZK, JED A, holds only 1 pending office action, which is the same as every other examiner in this large portfolio. This perfect one-to-one ratio between 48 pending actions and 48 distinct examiners indicates a completely decentralized prosecution environment. There is no concentration of cases, which prevents the company from using a consolidated strategy for multiple pending matters in the Biotechnology & Pharmaceuticals sector.
The presence of 27 distinct art units for 48 pending office actions reflects the wide technical range of the company's pharmaceutical innovations. Because the busiest examiner, KUCHARCZK, JED A, only handles 1 action, the company must manage 48 separate examiner relationships simultaneously. This distribution requires a highly versatile legal strategy to address the unique requirements and procedural trends of 27 different USPTO divisions.
Based on the USPTO statutory response window for each pending office action. 12 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. 12 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 (2%) |
| §101 + other | 1 (2%) |
| §103 only | 13 (27%) |
| §102 only | 2 (4%) |
| §112 only | 3 (6%) |
| Double-patenting only | 2 (4%) |
| Double-patenting + other | 8 (17%) |
| Multi-statute (no §101) | 18 (38%) |
