// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates outcomes across multiple art units within TC 2100. The allowance rate (88%) describes the examiner's historical record on decided cases and is not a prediction of outcome on any specific application. Aggregate statistics reflect past dispositions and do not vary by individual application characteristics. Art-unit-specific data may be available in a separate section and may show variation within the pool.

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 →
