This examiner grants 82% of resolved cases
Alvin J. Stewart is a patent examiner in Tech Center 3700 and Art Unit 1655. He has a substantial record of 1114 resolved cases. The examiner maintains an allowance rate of 82.1 percent, which indicates that a large majority of applications reach issuance. This percentage suggests that the examination process in this unit frequently results in a grant for the applicant.
The interview lift is 0.7 percent. This low figure suggests that conducting an interview does not significantly correlate with an increased likelihood of allowance for this examiner. The allowance rate remains relatively stable regardless of whether an interview is conducted. Practitioners should consider this 0.7 percent lift when deciding how to allocate resources during the prosecution of an application.
The median time to allowance is 1043 days. This timeframe provides a clear expectation for the duration of the prosecution cycle, showing that successful applications reach issuance within this median period. With 1114 resolved cases, these figures represent a stable set of outcomes for practitioners. The combination of the allowance rate and the median days to allowance defines the typical experience in Art Unit 1655.
