Analysis

Lunar Energy Inc. has 4 pending office actions in Semiconductors, Circuits & Optics. The matters are assigned to 4 distinct examiners and 4 distinct art units, so each action follows its own examiner and group combination.

PHAM, DUC M is the busiest examiner, with 1 pending matter. The absence of repeated examiner assignments makes application-specific preparation important, while the shared technology area may still support coordinated technical review.
