Analysis

WESTMAN CHAMPLIN & KOEHLER, P.A. operates in Medical Devices & Mechanical Engineering and reports 13910 career applications. It has 244 pending office actions, which indicates a substantial active examination workload. The resolved allowance rate is 90.32%, showing that a large share of resolved applications in the profile reached allowance.

The average of 3.47 office actions per allowance indicates that successful prosecution often involves several examination responses. The combination of a high application volume, a sizable pending docket, and a 90.32% allowance rate gives practitioners multiple lenses for review: scale, current workload, and recorded outcomes. The action average adds a separate measure of prosecution intensity and cautions against interpreting the allowance rate as evidence of a one-step process.
