Analysis

State Grid Corporation of China has 6 pending office actions in the Semiconductors, Circuits & Optics technology area. These 6 actions are distributed among 6 distinct examiners and 4 distinct art units. Because each of the 6 pending office actions is assigned to a different examiner, the company faces a variety of individual examination styles across its active matters.

MILLER, BETHANY MACKENZIE is the busiest examiner for the portfolio, currently overseeing 1 pending office action. The distribution across 4 distinct art units indicates that the company's semiconductor and optics work is being reviewed by several different specialized departments. With 6 distinct examiners involved, the company must manage 6 separate prosecution timelines and sets of examiner preferences, even though the work is concentrated in the Semiconductors, Circuits & Optics technology area.
