What the data says.

Xuxing Chen has a public record spanning 4 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 716 disposed applications, the examiner allowed 624, yielding an allowance rate of 87%.

This pooled record aggregates data from all four art units and describes the examiner's past dispositions without indicating the outcome of any particular application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled, cross-art-unit record aggregates allowance data from multiple art units into a single figure. The overall 87% allowance rate represents past decisions across all four units the examiner covers. This aggregate describes historical dispositions and is not a prediction of how any specific application will be examined or decided. The range across art units shows variation but does not identify which rate applies to which unit.

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 Xuxing Chen 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: 739 applications.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
