Analysis

Stratum Law LLC has 7 pending office actions in Medical Devices & Mechanical Engineering and 746 career applications. Its resolved allowance rate is 95.98%, indicating that nearly all resolved matters reached allowance in the reported record.

The average is 1.32 office actions per allowance, which points to comparatively limited examination activity in successful matters. The combination of the high allowance rate and low action average presents a record of favorable outcomes with relatively few reported actions per allowance. Practitioners should still distinguish these historical measures from the current pending docket when planning active responses.
