Examiner Dennis Butler has allowed 637 of 731 decided applications (87%) in Computer Architecture, Software, and Information Security.
Dennis Butler maintains a public record across 4 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 731 disposed applications, his allowance rate stands at 87%. The allowance rate ranges from 84% to 97% across these art units, reflecting variation in outcomes among the different art units in which he has examined. This pooled figure aggregates all decided applications—both allowed (637) and abandoned (94)—and represents his historical record across the technology center.
This pooled record combines outcomes from multiple art units under one examiner, creating an aggregate snapshot of past decisions. The overall allowance rate (87%) reflects all decided applications across all art units combined. The range (84% to 97%) shows that individual art units have performed differently. These figures describe what occurred in the past and are not predictions about any specific application 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 →
Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.
Primarily examines control or regulating systems, and electric power networks.

Methodology. This page pools every art unit in which Examiner Dennis Butler 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: 731 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.
