// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates one art unit's decided applications over time. The 63% allowance rate describes past dispositions—allowances as a share of applications that have been allowed or abandoned—and is not a prediction of outcomes in any specific application. Aggregate figures across art units describe historical data and vary by individual case, technology, claim scope, and prosecution history.

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 →
