Examiner Stephan F Willett has allowed 28 of 49 decided applications (57%) in Computer Architecture, Software, and Information Security.
Stephan F Willett maintains a public record across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 49 disposed applications, 28 were allowed and 21 were abandoned, yielding an allowance rate of 57%. This figure represents the share of decided applications in the examiner's pooled record. The record spans two art units within TC 2100, aggregating outcomes across those units. All 49 applications in the record have been disposed; no applications remain pending.
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 →
Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.

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.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes. 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.
