Analysis

Largan Precision Co., Ltd. has 31 pending office actions in the Semiconductors, Circuits & Optics technology area. These actions are handled by 27 distinct examiners, showing that the company's applications are broadly distributed across the examining corps. Despite this variety of examiners, the technical scope is narrow, with all actions falling into 4 distinct art units. This concentration within 4 distinct art units suggests that the company's semiconductor and optics innovations are being reviewed by a consistent set of technical groups.

RAKOWSKI, CARA E is the busiest examiner for the company, with 2 pending office actions. This low concentration among 27 distinct examiners highlights the decentralized nature of the 31 pending office actions. The focus on 4 distinct art units means that many of the 27 distinct examiners are working within the same technical divisions. Managing 31 pending office actions across 27 distinct examiners requires the company to adapt to many different individual examination styles while operating within a narrow technical framework of 4 distinct art units.
