Analysis

Teikyo University has 6 pending office actions in Biotechnology & Pharmaceuticals. Those matters involve 6 distinct examiners and 5 distinct art units, indicating that the docket is spread across examiners while remaining somewhat concentrated by technical group.

WRIGHT, ANDREW RUSSELL is the busiest listed examiner, with 1 pending action. No examiner carries a larger identified share of the docket, so response planning should be organized matter by matter. The 5-art-unit distribution also supports reviewing claim scope and technical framing separately for each assigned group rather than relying on a single prosecution position.
