// READING THIS EXAMINER

What the data says.

Examiner Thuy Chan Dao maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) across 2 art units. Over more than a thousand decided applications, the examiner's pooled allowance rate is 88%. This rate represents the share of applications that were allowed among all decided applications (allowed and abandoned combined) in the examiner's record. The allowance rate across the examiner's art units ranges from 87% to 97%, reflecting variation in outcomes across different subject-matter areas within TC 2100.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile aggregates the examiner's record across multiple art units within TC 2100. The pooled allowance rate of 88% describes historical outcomes across decided applications and is not a prediction about any specific application. Aggregate figures obscure per-art-unit variation; the range shown (87% to 97%) indicates that allowance rates differ among the examiner's individual art units. Historical statistics reflect past examination outcomes and do not forecast the result of any particular prosecution.

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 Thuy Chan 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 July 14, 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: 1,594 applications.

Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

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.
