// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile presents a pooled record—an aggregate of the examiner's work across multiple art units within TC 2100. The overall allowance rate (75%) and the range (63% to 84%) describe past dispositions and are not predictions of outcome for any specific application. Pooled data combines different art units and different cohorts of cases over time. Individual applications may fall anywhere within the art-unit range or outside it. Treat these figures as historical context, not as indicators of how any pending case will be examined.

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 Darrin D Dunn 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: 1,025 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.
