// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates allowance rates across multiple art units within TC 2100. The overall 78% figure describes historical outcomes across all decided applications and is not a prediction of any specific case. Individual art units may show different allowance rates; the range shown (17% to 80%) illustrates this variation. Pooled data provides context on past decisions but does not forecast the outcome of any particular application.

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 →
