Analysis

MIZUNO Corporation has 8 pending office actions in Medical Devices & Mechanical Engineering. Each matter is assigned to a different examiner, with 8 distinct examiners across 3 distinct art units. The technical grouping is narrower than the examiner distribution.

KAVANAUGH, JOHN T is the busiest examiner, with 1 pending matter. Counsel should use consistent device terminology and specification support across the three art units, but should not assume that one examiner’s treatment will carry across the docket. The assignment pattern favors centralized review of recurring claim concepts and separate analysis of each matter’s cited art.
