// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile aggregates the examiner's record across one art unit in TC 2100. The overall allowance rate of 50% describes historical outcomes on 135 decided applications and is not a prediction of outcomes in any specific case. Pooled figures mask variation within individual art units, which may be explored separately. Past disposition rates are correlational, not predictive.

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 →
