21 pending office actions • 15 art units • 18 examiners • 0 of 21 (0%) have an AI response strategy ready • 22 patents granted in the last 365 days
Lonza Ltd. has 21 pending office actions in the Biotechnology & Pharmaceuticals technology area. These actions span 15 distinct art units. The company works with 18 distinct examiners, which means that most of the 21 pending office actions are being reviewed by different individuals at the patent office. This high number of art units relative to the actions indicates a very broad technical portfolio.
TRAN, CHRISTINA L is the busiest examiner, managing 3 pending office actions. The remaining actions are distributed among other examiners. This distribution, where 18 distinct examiners handle 21 pending office actions, results in limited examiner overlap. With 15 distinct art units involved, practitioners must address the technical requirements of the 15 distinct art units. The portfolio involves 18 distinct examiners, requiring the company to manage these individual relationships simultaneously. Maintaining a cohesive strategy across 15 different specialized groups will be a key challenge for the prosecution team.
Based on the USPTO statutory response window for each pending office action. 8 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. 8 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 (10%) |
| §103 only | 8 (38%) |
| §112 only | 1 (5%) |
| Double-patenting + other | 8 (38%) |
| Multi-statute (no §101) | 2 (10%) |
How the docket's pending cases split across USPTO tech-center bands.
