Analysis

Citibank, N.A. has 17 pending office actions in Computing & Software. The matters involve 15 distinct examiners and 14 distinct art units, indicating that nearly every examiner and technical-unit assignment is separate within the reported portfolio.

TOKUTA, SHEAN S is the busiest examiner, with 2 pending actions. The limited concentration means centralized docket oversight should be paired with matter-specific examiner analysis. The close relationship between the number of actions, examiners, and art units also suggests limited opportunity to rely on one generalized prosecution approach across all cases.
