This examiner grants 100% of resolved cases

Analysis

Hannah Chinwe Nnabugwu serves in Tech Center 1700 and Art Unit 1747. The data is based on 3 resolved cases, which is an extremely small sample size for statistical evaluation. The allowance rate is currently 100.0%, and the median days to allowance is 1052. These figures provide an initial look at the examiner's performance but should be viewed as preliminary due to the low case count.

The interview lift is 0.0%, suggesting that interviews have not yet shown a statistical impact on the likelihood of grant for this examiner. Practitioners should monitor this 0.0% figure as more cases are resolved to see if a trend emerges. The 100.0% allowance rate is an ideal starting point, though it is likely to change with a larger caseload. The 1052 median days to allowance establishes a preliminary timeframe for successful prosecution. This analysis of Art Unit 1747 is grounded in the 3 resolved cases recorded.
