Examiner Dung K Chau has allowed 425 of 497 decided applications (86%) in Computer Architecture, Software, and Information Security.
Examiner Dung K Chau has disposed of 497 applications across three art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Of those decided applications, 425 were allowed and 72 were abandoned, yielding an allowance rate of 86%. The examiner's record spans art units 2153, 2161, and 2169. The allowance rate ranges from 68% to 96% across these art units, reflecting variation in outcomes within the examiner's pooled portfolio.
This pooled record aggregates the examiner's work across multiple art units within TC 2100. The overall allowance rate of 86% describes historical decisions on 497 disposed applications and is not a prediction of any specific application's outcome. Variation across individual art units (68% to 96%) illustrates that results differ by art unit. The pooled figure serves as a general reference to the examiner's past record only.
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 Dung K Chau 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: 497 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.
