FMC Corporation

Technology area: Biotechnology & Pharmaceuticals

9 pending office actions • 7 art units • 9 examiners • 0 of 9 (0%) have an AI response strategy ready • 7 patents granted in the last 365 days

Analysis

FMC Corporation currently maintains 8 pending office actions focused in the Biotechnology & Pharmaceuticals technology area. These 8 actions are distributed among 8 distinct examiners, meaning that every pending matter is being reviewed by a different official. This complete lack of examiner overlap across the 8 pending actions suggests that the portfolio contains a highly varied set of technical claims within the biotechnology sector.

The prosecution effort is spread across 7 distinct art units, showing that the 8 pending office actions are classified into several different technical categories at the patent office. KOSAR, ANDREW D is the busiest examiner for the portfolio, currently responsible for 1 pending office action. Since every one of the 8 distinct examiners is handling exactly 1 pending action, the workload is evenly distributed across the entire group. This parity across 8 distinct examiners and 7 distinct art units indicates a broad prosecution front where each of the 8 pending office actions likely requires a unique tactical approach.
