Analysis

Brandon Dongpa Lee is an examiner in Art Unit 2853, which is part of Tech Center 3700. He has 719 resolved cases, providing a substantial amount of data for analysis. The allowance rate for this examiner is 77.5 percent, which is a favorable and encouraging figure for patent applicants. The interview lift is 23.8 percent, suggesting that direct communication can provide a significant boost to the probability of allowance.
