Analysis

Iontra Inc. has 8 pending office actions in Semiconductors, Circuits & Optics. The matters involve 6 distinct examiners and 3 distinct art units, creating more examiner variation than art-unit variation. This structure suggests that several matters are grouped within the same technical units while being handled by different examiners.

MCFARLAND, DANIEL PATRICK is the busiest examiner with 2 pending matters. The assignment is not the sole center of the portfolio, so counsel should distinguish examiner preferences from art-unit practice when preparing responses. The smaller art-unit spread may support art-unit-level coordination, while the broader examiner spread calls for individualized prosecution histories.
