Examiner Paul E Callahan has allowed 113 of 151 decided applications in Computer Architecture, Software, and Information Security.
Paul E Callahan maintains a public record across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His pooled allowance rate across all art units is 75%. This figure represents the share of his decided applications—those allowed or abandoned—and does not include pending applications. The examiner's record spans 3 art units within TC 2100. The allowance rate is calculated from the total population of applications with final dispositions across these art units and reflects historical outcomes only.
This pooled record aggregates outcomes across multiple art units within TC 2100, creating a single allowance-rate figure that represents past decisions. Aggregate percentages describe the examiner's historical record and are not predictions of any specific application's outcome. Because different art units may have different subject-matter profiles and applicant populations, a pooled rate provides a broad overview but does not forecast how any individual application will be examined or decided.
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 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 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: 151 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.
