Analysis

Carbon Pesa Limited has 2 pending office actions in Transportation, E-Commerce & Mechanical Systems. The matters span 2 distinct examiners and 2 distinct art units, so prosecution management must account for separate examination contexts.

WHITAKER, ANDREW B is the busiest examiner, with 1 pending matter. Because the busiest examiner handles only part of the docket, counsel should avoid assuming that one response strategy will address both matters.
