Analysis

Derrick Corporation has 3 pending office actions in the Transportation, E-Commerce & Mechanical Systems technology area. These actions are distributed across 3 distinct examiners and 2 distinct art units. This means that every one of the 3 pending office actions is being reviewed by a different individual.

The busiest examiner is MATTHEWS, TERRELL HOWARD, who is handling 1 of the 3 pending office actions. Since there are 3 distinct examiners for 3 actions, each examiner is managing exactly 1 case. This distribution requires the company to manage 3 separate examiner relationships for its current active filings. Practitioners should be prepared for 3 unique prosecution styles across the 3 pending office actions.

The 3 pending office actions are spread across 2 distinct art units within the Transportation, E-Commerce & Mechanical Systems sector. This variety suggests that the applications cover different technical sub-fields. Practitioners should anticipate that the 3 distinct examiners will each bring a unique perspective to the 3 pending office actions across these 2 art units. MATTHEWS, TERRELL HOWARD, as the busiest examiner with 1 action, represents the even spread of the current workload.
