// READING THIS EXAMINER

What the data says.

Darrin D Dunn maintains a public record across 4 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). His pooled allowance rate stands at 75% across hundreds of decided applications. This rate reflects the percentage of applications in his record that were allowed or abandoned, excluding pending matters. The allowance rate ranges from 63% to 84% across his art units, indicating variation in outcomes by subject matter within the technology center. The pooled figure aggregates these distinct units into a single overall measure of his decided-application record.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates data across multiple art units, masking unit-by-unit variation beneath a single overall figure. The 75% allowance rate describes past outcomes on decided applications and is not a prediction of any specific application's outcome. The range from 63% to 84% shows that individual art units within TC 2100 produced different rates. Pooled statistics describe historical record only; they do not forecast results in any particular case or art unit.

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 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 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: 1,025 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.
