Analysis

Steven N Leff is an examiner in Tech Center 1700 and Art Unit 1782. With 574 resolved cases, the allowance rate is 41.3 percent. The interview lift is 7.9 percent, which is a small boost to the chances of allowance.

The median days to allowance is 1383. This is a long timeline for the 574 resolved cases. The 41.3 percent allowance rate is below a majority, and the 7.9 percent interview lift suggests that interviews have a limited impact.

Practitioners should be aware of the 1383 median days to allowance. The allowance rate is a challenging baseline in Art Unit 1782. The interview lift across resolved cases shows that while interviews are helpful, they may not be as effective as in other dockets. This data set provides a clear expectation for a rigorous examination process.
