Analysis

Redwood Materials Inc. currently has 3 pending office actions within the Chemistry & Materials technology area. These matters are assigned to 3 distinct examiners. The prosecution activity is distributed across distinct art units. These counts show that every pending matter is handled by a different reviewer in a different administrative unit. This distribution provides a variety of examiner perspectives and reduces the concentration of risk within the portfolio.

FORRY, COLTON BUSA is the busiest examiner for the company and is responsible for 1 pending office action. This busiest examiner pending count of 1 is less than the total workload. Because the pending office actions are split among the assigned staff, the company's success does not depend on a single reviewer. Practitioners must manage different examination styles across the distinct examiners and art units. This arrangement requires a strategy that accounts for the specific requirements of each assigned reviewer. The current prosecution profile is characterized by this distribution of matters across the staff.
