Analysis

Michael A. Lyons is an examiner in Tech Center 3700, specifically Art Unit 2871. With 961 resolved cases, the examiner has an allowance rate of 86.5 percent.

This baseline provides a clear statistical expectation of success. The large number of resolved cases ensures that these metrics are based on a substantial and reliable history of examination outcomes.

The median days to allowance is 808, which indicates an efficient timeline for the prosecution process from filing to grant. The interview lift is 10.0 percent, showing that interviews provide a modest but useful boost to the already high 86.5 percent probability of success. For practitioners, this indicates that while the baseline is favorable, interviews remain a productive tool for resolving any remaining issues. These metrics together help in developing a strategic approach for applications assigned to Art Unit 2871, where both speed and grant probability are high.
