Analysis

Unicharm Corporation has 11 pending office actions in Chemistry & Materials. The matters involve 11 distinct examiners and 4 distinct art units. Examiner assignment is fully distributed, while the smaller art-unit figure indicates repeated prosecution activity within those units.

DUBOIS, PHILIP A is the busiest examiner, with 1 pending matter. No examiner accounts for a larger identified workload, so the principal coordination opportunity lies in art-unit and technology review rather than examiner concentration.

Counsel may benefit from maintaining a shared position on recurring Chemistry & Materials issues while preserving response plans tailored to each examiner. The combination of broad examiner distribution and narrower unit distribution makes internal docket organization especially important.
