Analysis

Thermo Finnigan LLC has 14 pending office actions in Semiconductors, Circuits & Optics. The portfolio spans 13 distinct examiners and 8 distinct art units, indicating broad examiner dispersion and meaningful technical-group distribution. Coordination will need to address variation in both examiner practice and art-unit context.

CHOI, JAMES J is the busiest examiner, with 2 pending matters. That assignment offers a limited point of concentration for targeted review, but most actions remain distributed elsewhere. Counsel should use centralized issue tracking while preserving separate response strategies for the different examination settings.
