// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates data across multiple art units, presenting the examiner's overall allowance rate as a historical summary. The 51% figure describes past decisions on 442 disposed applications and reflects the combined result across different subject-matter areas. This aggregate is descriptive of prior work, not predictive of any specific application's fate.

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. 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: 467 applications.
