Examiner Andrew T Caldwell has allowed 48 of 116 decided applications (41%) in Computer Architecture, Software, and Information Security.
Andrew T Caldwell holds a public record of 123 total applications across 6 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Of 116 disposed applications, 48 were allowed, yielding an allowance rate of 41%. Across his art units, allowance rates range from 10% to 51%, reflecting variation in the examiner's record by subject matter and art-unit grouping. This pooled figure represents the aggregate of decided cases and does not predict outcomes in any individual application.
A pooled record aggregates disposal and allowance data across multiple art units, smoothing variation to show overall historical performance. The 41% rate describes past decisions on 116 disposed applications and is a correlation, not a prediction of future action. The range (10% to 51%) illustrates how rates differ among the examiner's individual art units. Pooled figures are descriptive of record only and do not indicate how any specific 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.
Primarily examines data-processing methods for specific functions, and processing data by its order or content.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 26 decided applications with an interview and 48 without.
Primarily examines program control and execution.
Based on 20 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Primarily examines neural-network / biological-model computing, and machine learning.
Primarily examines information retrieval and database structures.

Methodology. This page pools every art unit in which Examiner Andrew T Caldwell 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: 123 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.
