Analysis

Leon B Lankford Jr works in Tech Center 1700 and Art Unit 1651 with 751 resolved cases. His allowance rate pct is 70.0, and the median days to allowance is 1353. These figures indicate the path to allowance for applicants. The 1353-day median to allowance is a benchmark for applicants navigating Art Unit 1651 and managing their patent portfolios.

The interview lift pct of 31.6 is a metric suggesting that interviews are a component of a successful strategy. This 31.6 lift indicates that verbal advocacy can increase the 70.0 allowance rate pct. The 751 resolved cases provide a statistical foundation for these observations. A 31.6 lift is a signal that direct communication is an effective way to move an application toward a grant with this examiner and potentially address the 1353-day median pendency.
