Examiner Marc M Duncan has allowed 1,112 of 1,256 decided applications (89%) in Computer Architecture, Software, and Information Security.
Marc M Duncan holds a public record of 1,283 total applications across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Of 1,256 disposed applications, 1,112 were allowed, yielding an allowance rate of 89%. The remaining 144 applications were abandoned. This pooled figure represents the examiner's aggregate record across all assigned art units and reflects decisions made on applications that have reached final disposition, excluding any pending matters.
This pooled record aggregates data across multiple art units within TC 2100. The allowance rate of 89% describes the historical share of decided applications that were allowed and is calculated from disposed applications only—pending cases are excluded. Pooled figures describe past dispositions and do not constitute a prediction of outcome for any specific application, which depends on individual claim scope, prior art, and prosecution history.
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 error detection, correction, and monitoring.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 221 decided applications with an interview and 1,031 without.
Primarily examines interconnection and data transfer between memory, I/O, and processing units.
Methodology. This page pools every art unit in which Examiner Marc M Duncan 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: 1,283 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.
