Analysis

Deming Wan has managed 942 resolved cases in Art Unit 3746 of Tech Center 3700. The examiner's allowance rate is 76.4 percent, indicating a high likelihood of grant for applications that meet the necessary technical requirements. This 76.4 percent rate suggests that the examiner is generally cooperative and willing to work with applicants to reach a positive conclusion.

Efficiency is reflected in a median days to allowance of 912, which is an efficient timeline for reaching a final grant. The interview lift of 42.4 percent highlights the significant impact of examiner interviews, which are much more likely to result in an allowance than non-interviewed applications.

Given the 76.4 percent baseline allowance rate, an interview is a powerful strategy to ensure a positive outcome and potentially maintain the 912 day efficiency.
