// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines results across all art units where an examiner has a substantial presence. The aggregate allowance rate describes historical outcomes across those units combined and is not a prediction of any specific application's fate. Individual art units may show different rates; the range provided reflects this variation. Pooled statistics are most useful as a general reference to past patterns.

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 →

METHODOLOGY & DISCLOSURES

Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated June 25, 2026. The overall allowance rate is total allowed divided by total decided applications (allowed plus abandoned) across all art units — not an average of the per-art-unit rates; pending applications are excluded. Figures are rounded for display. Pooled sample: 750 applications.

Where this page compares an examiner's allowance rate to an art-unit average, that comparison is a factual description of the public record, not a characterization of any individual examiner's conduct or competence.
