// READING THIS EXAMINER

What the data says.

Examiner Thuy T Bui maintains a public record across 4 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). The pooled allowance rate is 80% across hundreds of decided applications. The allowance rate ranges from 57% to 86% across the examiner's art units. This range reflects variation in the record within different areas of the technology center. The aggregate figures describe the examiner's past disposition of applications across all tracked art units and do not constitute a prediction for any specific pending application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates data across multiple art units, presenting an overall allowance rate rather than unit-specific rates. The 80% figure describes historical outcomes across all of the examiner's decided applications in TC 2100. The reported range (57% to 86%) identifies the breadth of variation among individual art units. These historical figures are descriptive only and are not predictions about any single application's 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 →

// BY ART UNIT

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Thuy T Bui 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: 592 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.
