// READING THIS EXAMINER

What the data says.

Examiner Le Hien Luu maintains a public record of 240 disposed applications in Technology Center 2100 (Computer Architecture, Software, and Information Security), spanning 2 art units. Of these decided applications, 189 were allowed and 51 were abandoned, yielding an allowance rate of 79%. This pooled figure represents the examiner's overall record across both art units combined and does not isolate outcomes by individual art unit or technology specialty.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's work across multiple art units into a single metric. The 79% allowance rate reflects historical outcomes across all cases in those units combined. This aggregate figure describes what occurred in the past and is not a prediction about any specific future application. Individual art-unit records, available separately, may show variation from the pooled average.

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 Le Hien Luu 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: 240 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.
