Examiner Bai Duc Vu has allowed 632 of 799 decided applications (79%) in Computer Architecture, Software, and Information Security.
Bai Duc Vu maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning three art units: 2162, 2163, and 2165. Across 799 decided applications, the examiner has allowed 632, yielding an allowance rate of 79%. The 167 abandoned applications are included in this decided count. Allowance rates across the three art units range from 73% to 98%, reflecting variation in outcomes by art unit. This pooled figure represents the aggregate record and does not predict outcomes in any individual application.
This pooled record aggregates data across three separate art units in TC 2100. The 79% allowance rate describes past decisions on 799 applications that reached final disposition—neither pending cases nor future applications. The range of 73% to 98% indicates that individual art units within this examiner's portfolio show different allowance rates. Pooled figures describe historical record; they are not forecasts of any specific case outcome.
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 Bai Duc Vu 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: 826 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.
