Examiner Paul E Callahan has allowed 113 of 151 decided applications (75%) in Computer Architecture, Software, and Information Security.
Paul E Callahan maintains a public record across three art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 151 disposed applications, he allowed 113 and abandoned 38, for an overall allowance rate of 75%. This rate reflects the aggregate outcome of decided cases pooled across all three art units within TC 2100. The breadth of his record spans multiple art units, meaning the pooled figure represents an average across different subject areas and examination contexts within the technology center.
A pooled, cross-art-unit record aggregates dispositions across multiple art-unit assignments and presents a single allowance rate as a historical average. This aggregate figure describes the examiner's past record and is not a prediction of any specific application's outcome. Individual art units may exhibit different allowance rates; a separate section displays per-art-unit detail. Pooled data is useful for understanding broad patterns in an examiner's decisions but does not account for case-by-case variation.
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 input/output (I/O) data transfer, and memory access and allocation.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 47 decided applications with an interview and 92 without.
Primarily examines network security, and computer and data security.

Methodology. This page pools every art unit in which Examiner Paul E Callahan 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: 151 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.
