// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates all applications handled by the examiner across their art unit(s). The allowance rate of 59% describes the historical share of decided applications that were allowed and represents the examiner's past record only. Aggregate figures do not predict outcomes in any individual case. Different applications may proceed differently based on claim scope, prior art, and prosecution history.

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 Alexander J Yoon 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: 265 applications.
