What the data says.

Kieu D Vu maintains a public record across 3 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 257 decided applications, the examiner's pooled allowance rate is 44%, with 114 allowed and 143 abandoned. The allowance rate across the examiner's art units ranges from 27% to 98%, reflecting variation in outcomes by art unit. This pooled figure aggregates the examiner's record across multiple distinct art units and does not represent any single unit's performance.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines an examiner's outcomes across multiple art units into a single aggregate metric. The overall allowance rate of 44% reflects past decisions on 257 applications across all three art units combined. This aggregate is historical data only—a description of what occurred, not a prediction about any specific application. Individual art units may show different rates; those figures appear separately in the per-art-unit section.

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 & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Kieu D 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: 266 applications.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
