2 pending office actions • 1 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready

Analysis

Circadian Os Inc. has 2 pending office actions within the Semiconductors, Circuits & Optics technology area. Although these actions are handled by 2 distinct examiners, they originate from 1 distinct art unit. This indicates that while the specific examiners vary, the technical evaluation remains centralized within a single administrative group at the patent office.

The busiest examiner, SONG, ZHENG B, is responsible for 1 pending office action. With the total pending actions split between the examiners, the company faces a risk profile where no single examiner controls the majority of the pending portfolio. This distribution requires monitoring individual examiner tendencies within the shared art unit.
