Examiner Cao H Nguyen maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning 2 art units: 2171 and 2173. Across 1,475 disposed applications, the examiner allowed 1,334, yielding an allowance rate of 90%. The allowance rate ranges from 87% to 92% across these art units.

This pooled record aggregates Examiner Nguyen's work across multiple art units in TC 2100. The figures describe past dispositions and are not predictions about any specific application. An aggregate allowance rate across art units masks variation; applicants may wish to review the examiner's separate per-art-unit records to understand patterns within individual art units. Pooled statistics are correlational summaries, not causal indicators of how any particular application will be handled.
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. This page pools every art unit in which Examiner Cao H 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: 1,505 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.
