// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines statistics from multiple art units into a single aggregate profile. The overall allowance rate describes past dispositions across all art units handled by the examiner and is not a prediction of any specific application's outcome. Different art units may have different allowance rates; the range shown reflects variation among them. Pooled figures are correlational summaries of past work, not predictive models.

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 Thuan N Du 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: 684 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.
