Analysis

Koji Tanabe currently has 2 pending office actions within the Biotechnology & Pharmaceuticals technology area. These 2 actions are assigned to 2 distinct examiners, ensuring that each case is evaluated by a different person. Both of these pending office actions are situated within 1 distinct art unit, showing a concentrated technical classification for the portfolio.

PYLA, EVELYN Y is the busiest examiner for this portfolio, currently responsible for 1 pending office action. This 1 action is the highest number assigned to any single examiner for these cases. The distribution of 2 pending office actions across 2 distinct examiners within 1 distinct art unit means that practitioners will encounter two different examination styles for very similar technology. This arrangement requires a strategy that accounts for the individual preferences of 2 distinct examiners, even though the cases reside in the same 1 distinct art unit. The 2 pending office actions represent the total active workload for the company in the Biotechnology & Pharmaceuticals sector.
