Analysis

KOTTER, STEPHEN SUTTON serves in tech center 2800 and art unit 2828. The record contains 102 resolved cases, an allowance rate of 66.7%, an interview lift of 38.6%, and a median of 1261 days to allowance. Cases associated with interviews had a higher allowance outcome than the overall record.

Mitsubishi Electric Corporation is the listed company, and BUCHANAN, INGERSOLL & ROONEY PC is the listed firm. The positive interview lift supports considering examiner discussion as part of a response strategy, particularly when the applicant can explain the technical distinction without relying only on amendment. The resolved-case volume provides a useful, though bounded, historical sample. The median timing indicates that prosecution may continue for a substantial period, so applicants should coordinate interview timing, amendment decisions, and continuation planning accordingly.
