Analysis

Subsea 7 Limited manages 3 pending office actions within the Transportation, E-Commerce & Mechanical Systems technology area. These actions are distributed among 3 distinct examiners, indicating that each examiner is currently reviewing a single application. This distribution across 3 distinct examiners suggests that the company must prepare for 3 different examination styles within the Transportation, E-Commerce & Mechanical Systems sector. A practitioner must monitor 3 separate prosecution timelines simultaneously.

The portfolio is active across 2 distinct art units, which is fewer than the 3 distinct examiners involved. FIORELLO, BENJAMIN F is the busiest examiner with 1 pending office action, which is 1 of the 3 pending office actions currently facing the company. Because the busiest examiner only has 1 pending office action, the workload is evenly spread, and no single examiner has a dominant influence over the 3 pending office actions. Practitioners should note that while the 3 distinct examiners are separate, they are concentrated within only 2 distinct art units.
