Analysis

KOZIOL, STEPHEN R works in tech center 4100 and art unit 1687. The profile records 398 resolved cases, an allowance rate of 77.6%, an interview lift of 25.1%, and a median of 1379 days to allowance. Cases associated with interviews had a higher allowance outcome than the overall record.

The positive interview lift supports considering interviews when the applicant can explain the technical contribution and narrow the disputed issues. The allowance rate provides a useful historical reference, but the median timing indicates that reaching allowance may require a prolonged prosecution path. Practitioners should align response strategy, interview preparation, and continuation decisions with that timing.
