This examiner grants 14% of resolved cases

Analysis

Victor Chigozirim Esonu is an examiner in Tech Center 3600 and Art Unit 3629. The data reflects a small sample size of 7 resolved cases, which results in an allowance rate of 14.3 percent. This low rate indicates a challenging path to allowance for current applications, requiring practitioners to be exceptionally thorough in their initial filings and subsequent responses.

The interview lift is recorded at 0.0 percent, suggesting that interviews have not yet demonstrated a statistical benefit for the 7 resolved cases handled by this examiner. Additionally, the median days to allowance is 1006, representing the typical timeframe for the few cases that do reach a grant. Given the 14.3 percent allowance rate, practitioners should be prepared for rigorous examination and a potentially difficult prosecution cycle. The 1006-day timeline and 0.0 percent lift suggest that traditional written arguments have been the primary mode of resolution thus far.
