// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates examination data across a single art unit. The 69% allowance rate describes the examiner's past decisions on closed applications and is not a prediction of any specific case outcome. Aggregate statistics reflect historical patterns but vary by application complexity, claim scope, prior art, and individual prosecution history. Any single application's disposition depends on its particular facts and evidence.

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 Zujia Xu 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: 217 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.
