// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates applications across all art units in which the examiner has decided cases. The 88% allowance rate describes past dispositions (allowed plus abandoned) divided by all decided applications. Pooled figures mask variation within and across art units. An aggregate rate is a historical summary and is not a prediction of the outcome of any specific application currently pending or future filing.

These are aggregate statistics from this examiner's past public record — not predictions about any specific application. The per-art-unit figures below show how the record varies across art units. Our approach to patent prosecution →

Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated June 25, 2026.
