// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates outcomes across all art units in which the examiner has worked. The allowance rate (93%) describes past-decided applications only and is not a prediction of outcomes on any specific pending case. Pooled figures mask variations across individual art units; per-art-unit data, where available, may reveal subject-matter differences within TC 2100.

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 →
