Analysis

Linden Research Inc. is managing 5 pending office actions within the Communications technology area. The portfolio shows significant diversity in its examination path, as these actions are spread across 5 distinct art units and multiple distinct examiners. This high level of dispersion indicates that the company's patent applications cover a broad range of technical sub-sectors within the Communications field.

This distribution means that every pending matter is being evaluated by a different individual in a different technical group. COFINO, JONATHAN M is identified as the busiest examiner with 1 busiest examiner pending action. Because each examiner holds a particular action, the company faces a broad range of examiner behaviors and art unit norms. Managing 5 pending office actions across 5 distinct art units requires a versatile prosecution strategy to address the varied requirements of each examiner. This decentralized structure prevents any single art unit from becoming a bottleneck for the company's Communications technology goals.
