// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates all applications decided by the examiner across their assigned art unit(s) within TC 2100. Aggregate allowance rates describe past outcomes pooled over time and subject matter within that unit. Figures are correlational summaries of the examiner's historical record, not predictions of outcome in any single case. Individual applications vary by claims, prior art, and office action responses.

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 →
