Analysis

DISCOVERY PURCHASER CORPORATION has 4 pending office actions in the Biotechnology & Pharmaceuticals technology area. These 4 actions are split among 4 distinct examiners and 4 distinct art units. This one to one ratio indicates that each pending application is being treated as a unique technical and procedural matter by the USPTO.

GINA CHIEUN YU JUSTICE is the busiest examiner with 1 pending action. Because each of the 4 actions is in a different art unit and with a different examiner, there is no overlap in the current pending set. Practitioners must develop 4 separate strategies to address the specific requirements of each examiner and art unit involved in these 4 pending office actions.
