Sub-Drill Supply Limited

Technology area: Transportation, E-Commerce & Mechanical Systems

2 pending office actions • 2 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready

Analysis

Sub-Drill Supply Limited currently has 2 pending office actions in the Transportation, E-Commerce & Mechanical Systems technology area. These 2 actions are assigned to 2 distinct examiners across 2 distinct art units. This structure shows that each pending matter is being handled by a unique examiner in a unique art unit, providing no overlap in the current prosecution landscape. The use of 2 distinct art units for only 2 actions suggests that the company's technologies are being classified into different specialized categories.

The busiest examiner for this portfolio is WOOD, DOUGLAS S, who is responsible for 1 pending office action. With 2 pending actions and 2 distinct examiners, the workload is evenly distributed between the individuals involved. This ratio between actions and examiners requires the company to manage separate negotiation processes for each matter. Furthermore, because the 2 actions are in 2 distinct art units, practitioners must navigate different sets of art unit-specific guidelines and technical standards within the USPTO.
