Analysis

Spirit AeroSystems Inc. has 11 pending office actions in Chemistry & Materials. Those matters are distributed among 11 examiners and 9 art units, showing a broad prosecution footprint with little examiner concentration. The docket calls for coordination across multiple examination practices, while preserving application-specific analysis of claim scope, written description, and prior-art issues.

CRANDALL, JOEL DILLON is the busiest examiner, but has only 1 pending matter. The distribution means that no single examiner accounts for a dominant share of the reported activity. Counsel may benefit from a centralized issue chart that identifies common technology or claim themes while allowing responses to reflect the different art-unit contexts.
