// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines all art units under an examiner's supervision into a single aggregate. The allowance rate reflects the share of decided applications that were allowed, excluding pending filings. Aggregate historical rates describe past outcomes across multiple applications and art units; they do not predict the outcome of any specific case and are not causal—they correlate examiner behavior with results but do not explain why outcomes occurred.

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 Yu Zhao 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: 407 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.
