// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates data across multiple art units, each handling distinct subject-matter areas within TC 2100. The 87% allowance rate describes past outcomes on 906 decided applications and is not a prediction of any specific application's outcome. Aggregate figures mask variation—the 80% to 96% range shows that allowance rates differ among the art units included here. Individual applications may fall anywhere within or outside historical ranges depending on claim scope, prior art, and examination specifics.

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 →

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Zahid Choudhury has a public record within Technology Center 2100. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated June 25, 2026. The overall allowance rate is total allowed divided by total decided applications (allowed plus abandoned) across all art units — not an average of the per-art-unit rates; pending applications are excluded. Figures are rounded for display. Pooled sample: 927 applications.
