Dong-A St Co. Ltd.

Technology area: Biotechnology & Pharmaceuticals

4 pending office actions • 3 art units • 4 examiners • 0 of 4 (0%) have an AI response strategy ready

Analysis

Dong-A St Co. Ltd. currently has 3 pending office actions in the Biotechnology & Pharmaceuticals technology area. These actions are distributed among 3 distinct examiners, meaning each official is reviewing one case. The portfolio is spread across 2 distinct art units, indicating some technical variety within the biotechnology sector. This distribution of 3 pending actions across 3 distinct examiners requires the company to manage three separate examiner relationships simultaneously.

ONDACHI, PAULINE WANJIKU MUCH is the busiest examiner with 1 pending office action. With 3 pending actions and 2 art units, the company faces a relatively concentrated administrative environment despite the involvement of 3 distinct examiners. This structure allows for some comparison of examiner behavior within the same technical divisions, as the 2 distinct art units provide the primary procedural framework. Practitioners should focus on identifying the specific trends within the 2 distinct art units to better predict the behavior of the 3 distinct examiners. While each of the 3 pending office actions must be addressed individually, the departmental standards of the 2 art units will provide the necessary context for successful prosecution.
