// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates all disposed applications across the examiner's assigned art units into a single pooled allowance rate. The 85% figure describes past decisions and is not a forecast for any specific application. Pooled rates combine different art units and subject areas; individual applications may experience different patterns. Historical statistics describe what occurred, not what will occur in future cases.

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 →
