Examiner Chau T Nguyen has allowed 421 of 640 decided applications (66%) in Computer Architecture, Software, and Information Security.
Chau T Nguyen has a public record spanning 3 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 640 disposed applications, the examiner allowed 421, for an allowance rate of 66%. The allowance rates across these art units range from 50% to 90%. This pooled figure aggregates outcomes across distinct subject areas and does not represent a prediction for any individual application.
This record pools decisions across multiple art units in TC 2100. The 66% allowance rate describes past outcomes on 640 decided applications and reflects aggregate performance across different examination areas. Pooled figures describe historical data, not probabilities for specific cases. Individual art-unit rates may differ substantially from the overall figure.
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 →
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. This page pools every art unit in which Examiner Chau T Nguyen 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: 680 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.
