Analysis

Northrop Grumman Systems Corporation manages 13 pending office actions in the Semiconductors, Circuits & Optics technology area. These matters are distributed across 9 distinct art units, reflecting a technical footprint within the sector. The prosecution involves 13 distinct examiners, meaning each pending action is currently assigned to a unique individual at the patent office. This distribution of actions and examiners suggests that the company's legal team must adapt to a variety of individual examination styles simultaneously.

The busiest examiner for the company is LUONG, HENRY T, who is responsible for 1 pending office action. This workload is identical for all 13 examiners involved in the 13 pending actions, indicating no concentration of cases under any single official. The distribution across 9 distinct art units suggests that the company's Semiconductors, Circuits & Optics filings are being evaluated by many different technical groups. Without any examiner overlap, the company must manage 13 separate interactions and sets of feedback. This structure requires a versatile prosecution strategy to address the technical requirements of 13 different examiners across 9 art units. The number of distinct art units relative to the 13 pending actions highlights the specialized nature of each individual application.
