Analysis

3M Company has 97 pending office actions in Medical Devices & Mechanical Engineering. The portfolio spans 76 distinct examiners and 43 distinct art units, reflecting broad prosecution activity across both examination personnel and technical classifications.

NGO, MEAGAN N is the busiest examiner, with 6 pending matters. That examiner handles a visible cluster, but the portfolio remains widely distributed beyond that assignment. The scale and spread support a structured docket program that tracks art-unit tendencies, preserves reusable technical positions, and distinguishes examiner-specific response strategies from company-wide claim priorities.
