Examiner Patrick A Darno has allowed 72 of 147 decided applications (49%) in Computer Architecture, Software, and Information Security.
Patrick A Darno maintains a public record across three art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 147 disposed applications, the examiner's allowance rate stands at 49%, meaning 72 applications were allowed and 75 abandoned. The record spans multiple art units—2158, 2163, and 2169—with allowance rates ranging from 31% to 60% across these units. This range reflects variation in the examiner's record within the technology center. The figures presented describe the examiner's past decisions and do not constitute predictions about any future application.
This pooled record aggregates decisions across three separate art units, each potentially covering distinct subject matter within TC 2100. The overall 49% allowance rate is a composite figure across all three units and reflects the examiner's historical disposition pattern. The range of 31% to 60% indicates that allowance rates vary among the individual art units. Aggregate statistics describe historical record only and are not forecasts of outcomes in any specific case.
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.

Methodology. This page pools every art unit in which Examiner Patrick A Darno 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: 147 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.
