What the data says.

Xuyang Xia maintains a public record across 2 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 489 disposed applications, the examiner allowed 356, for an allowance rate of 73%. The disposed count represents applications with final decisions (allowed or abandoned); 542 total applications include pending matters. This pooled figure aggregates the examiner's work across both art units and reflects the examiner's historical record in TC 2100 only.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines data from multiple art units into a single aggregate. The allowance rate—here 73% across 489 decided applications—describes historical output and does not predict outcomes in any particular application. Aggregate figures mask variation between individual art units; this profile shows the examiner's overall pattern, not performance within a specific art unit or on a specific invention.

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 →

// BY ART UNIT

The record, art unit by art unit.

Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Xuyang Xia 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: 542 applications.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes. 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.
