Analysis

Willow Laboratories Inc. has 12 pending office actions in Medical Devices & Mechanical Engineering. The matters involve 12 distinct examiners across 6 distinct art units. The matching action and examiner figures indicate that each matter has a distinct examiner in the available data, while the smaller art-unit figure indicates technical grouping across the docket.

BLANCHETTE, JOSHUA B is the busiest examiner, with 1 pending matter. Examiner-level coordination is consequently limited. Counsel may instead benefit from organizing responses by the 6 art units and identifying common device or mechanical issues within those technical assignments.

Written from this page's own data; every figure is computed from USPTO records and verified before publication.
