// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's outcomes across multiple art units, producing a single allowance rate that spans different subject areas within the technology center. This aggregate figure describes the examiner's historical record and is not a prediction of the outcome of any specific application. Individual art units may have different rates, characteristics, and volumes; the pooled view shows an overall baseline only.

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

Methodology. This page pools every art unit in which Examiner Stephan F Willett has a public record within Technology Center 2100. 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: 49 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.
