// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates data across all art units in which the examiner works. The allowance rate (85%) and disposal counts describe the examiner's historical record and reflect applications already decided. Aggregate figures do not constitute a prediction of any specific application's outcome. Individual art-unit records, where available, may show variation from these pooled statistics.

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 Charles J Choi 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: 396 applications.

Where this page compares an examiner's allowance rate to an art-unit average, that comparison is a factual description of the public record, not a characterization of any individual examiner's conduct or competence.
