Examiner Xi Donald Chen has allowed 145 of 195 decided applications (74%) in Computer Architecture, Software, and Information Security.
Examiner Xi Donald Chen's public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spans one art unit. Across 195 disposed applications, 145 were allowed and 50 were abandoned, yielding an allowance rate of 74%. This rate reflects decisions on applications that have reached final disposition. The record represents the examiner's pooled output across all assigned art units and does not predict outcomes for any particular pending application.
This pooled record aggregates examination activity across all of the examiner's art units in TC 2100. The allowance rate and application counts describe past dispositions only and are not predictions for any specific case. Pooled figures obscure variation among individual art units; applicants seeking art-unit-specific data may consult the per-unit breakdown elsewhere on this page.

Methodology. This page pools every art unit in which Examiner Xi Donald 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: 195 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.
