Examiner Tuan C. Dao has allowed 750 of 894 decided applications (84%) in Computer Architecture, Software, and Information Security.
Examiner Tuan C. Dao's public record spans 3 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 894 disposed applications, the examiner allowed 750, yielding an overall allowance rate of 84%. The allowance rate varies across art units, ranging from 77% to 94%. This pooled figure represents the examiner's aggregate record and does not characterize performance on any single application.
A pooled record aggregates data across multiple art units, producing an overall allowance rate that masks unit-by-unit variation. The 84% figure is a historical summary of decided cases and is not a prediction of how any given application will be examined. Individual art-unit rates may differ materially from the pool. For analysis of specific art units, refer to the per-unit breakdown section of this profile.
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 Tuan C. Dao 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: 936 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.
