// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile pools the examiner's record across two art units in TC 2100. Pooled figures represent aggregate history and do not predict outcomes in any specific application. Allowance rates and application counts describe past dispositions. Individual art units may show different rates; those details appear separately. Pooled data is useful for understanding overall patterns but does not account for variation by art unit, technology, or application-specific factors.

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 Duy Khuong Thanh Nguyen 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.

Figures are rounded for display. Pooled sample: 627 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.

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.
