Analysis

Chun Kuan Lee is an examiner in Art Unit 2181, within Tech Center 2100. He has 686 resolved cases, providing a substantial amount of data for analysis. The allowance rate for this examiner is 68.4 percent, which is a moderate and balanced figure for applicants. The interview lift is 3.7 percent, suggesting that direct communication provides a small but positive benefit to the probability of allowance. This 3.7 percent lift is a factor for practitioners to consider when planning their interaction strategy.

The median time to allowance is 1226 days, which is over three years and indicates a relatively long prosecution cycle. This 1226-day timeline, combined with the 68.4 percent allowance rate, provides a clear expectation for the duration of the prosecution process. The 3.7 percent interview lift indicates that while interviews are helpful, they are not the primary driver of the examiner's decisions. With 686 resolved cases, the data reflects a consistent and professional examination style. Practitioners should focus on clear and persuasive written arguments to maintain efficiency. The 1226-day median pendency remains the primary benchmark for expected prosecution length. Overall, the data indicates that this examiner is both productive and consistent in his approach.
