Analysis

Corteva Agriscience LLC manages 13 pending office actions in the Biotechnology & Pharmaceuticals technology area. These actions cover 9 distinct art units. The company interacts with 13 distinct examiners for its 13 pending office actions, meaning every pending action is being reviewed by a different individual. This indicates a very broad range of technical subject matter being prosecuted simultaneously within the biotechnology sector.

ZHONG, WAYNESHAOBIN is the busiest examiner, though he handles 1 pending office action. This lack of examiner overlap across 9 distinct art units requires a prosecution strategy that accounts for 13 different individual reviewers. Practitioners must navigate the specific procedural standards of the 9 distinct art units involved. Because no cases currently share the same examiner, each of the 13 pending office actions requires a customized approach. The high number of art units further complicates the landscape, as it suggests the actions are subject to varying procedural standards.
