Analysis

Examiner Melvin C. Mayes operates within Tech Center 1700 and Art Unit 1700. He has overseen 126 resolved cases, maintaining an allowance rate of 34.1%. This metric indicates a more rigorous examination environment where roughly one-third of applications reach a grant. The median days to allowance for these successful cases is 1569, which serves as a benchmark for the expected duration of prosecution.

The data shows an interview lift of 5.2%. While this is a positive figure, it suggests that interviews provide a more modest benefit compared to other examiners. Given the 34.1% base allowance rate, practitioners should still consider interviews as part of their strategy, but they should also prepare for a potentially long 1569-day timeline. The volume of 126 cases provides a solid basis for these performance metrics. Direct engagement remains a useful tool for resolving specific hurdles in this art unit.
