Danisco US Inc. maintains a large portfolio of 27 pending office actions within the Biotechnology & Pharmaceuticals technology area. These actions are distributed across 22 distinct examiners, suggesting that while many examiners handle only one case, some are responsible for multiple matters. The portfolio spans 11 distinct art units, reflecting a broad range of biological and pharmaceutical research topics.
The busiest examiner, RAGHU, GANAPATHIRAM, is currently managing 2 pending office actions. This is a small portion of the 27 total pending office actions, indicating that the portfolio's success is not tied to any single examiner's discretion. The 22 distinct examiners involved provide a diverse set of perspectives on the company's applications.
With 11 distinct art units, the company must manage various examination styles and technical standards. The 2 pending office actions under RAGHU, GANAPATHIRAM are part of a larger effort that involves 22 distinct examiners across the Biotechnology & Pharmaceuticals sector. This diversity of 11 distinct art units requires a highly specialized approach to patent prosecution.
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 + other | 4 (14%) |
| §103 only | 4 (14%) |
| §112 only | 4 (14%) |
| Double-patenting only | 1 (4%) |
| Double-patenting + other | 4 (14%) |
| Multi-statute (no §101) | 11 (39%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
