Analysis

Holtec International has 8 pending office actions in Medical Devices & Mechanical Engineering. The matters are assigned to 8 distinct examiners and 6 distinct art units, so the portfolio is spread across several examination settings despite its limited number of pending actions.

STANEK, KELSEY L is the busiest identified examiner, with 1 pending matter. No single examiner accounts for more than the stated amount in the available profile, which points to a distributed prosecution workload. Counsel can therefore focus on application-level preparation while maintaining a concise docket view for the separate examiner and art-unit assignments.
