Analysis

Gardner, Linn, Burkhart & Ondersma LLP has a history in the Transportation, E-Commerce & Mechanical Systems technology area, having handled 3200 career applications. This volume of 3200 applications establishes the firm as a participant in this sector. Currently, the firm is managing 14 pending office actions, which represents the active portion of its docket.

The firm achieves a resolved allowance rate of 93.96 percent. This percentage is paired with an average of 2.49 office actions per allowance. These two figures together suggest a prosecution strategy that secures grants in the vast majority of cases while maintaining a specific number of 2.49 interactions per granted patent. This efficiency is a characteristic of their work in Transportation, E-Commerce & Mechanical Systems.

With 14 pending office actions, the firm continues to navigate the patent office's requirements for its clients. The 93.96 percent resolved allowance rate provides a benchmark for the firm's historical success. Practitioners can analyze the 2.49 average office actions per allowance to estimate the resources and time typically required to reach an allowance with this firm.
