Analysis

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.
