Clariant International Ltd. is currently navigating 12 pending office actions in the Biotechnology & Pharmaceuticals technology area. These actions are spread across 12 distinct examiners, showing that each pending matter is assigned to a different official. This distribution requires a broad prosecution strategy that accounts for the varied perspectives of 12 different individuals within the patent office, as no examiner's habits will define the portfolio's success.
The portfolio spans 6 distinct art units, indicating that the company's biotechnological and pharmaceutical interests are technically diverse. Nathan W Schlientz is the busiest examiner, though he holds 1 pending action. This lack of concentration among examiners suggests that no official's historical data will dominate the portfolio's overall success rate. With 12 pending office actions across 6 art units, the company faces a complex regulatory landscape that demands expertise across multiple pharmaceutical classifications.
The presence of 12 distinct examiners for the pending actions is a notable characteristic, suggesting that the company's filings are not being funneled to a specific group of officials. Practitioners should prepare for a range of examiner behaviors, as each official may have unique approaches to biotechnology claims. The 6 distinct art units involved further highlight the technical breadth of the company's current patenting efforts, making it essential to monitor trends across a significant portion of the USPTO's pharmaceutical divisions.
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 (15%) |
| §103 only | 2 (15%) |
| Multi-statute (no §101) | 9 (69%) |
