Examiner Diem K Cao has allowed 701 of 877 decided applications (80%) in Computer Architecture, Software, and Information Security.
Examiner Diem K Cao has a public record of 915 total applications spanning three art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Of 877 disposed applications, 701 were allowed, yielding an overall allowance rate of 80%. The allowance rate across the examiner's art units ranges from 71% to 83%, reflecting variation in outcomes within the technology center. This pooled figure aggregates decisions across multiple art units and represents the examiner's historical record rather than a prediction of outcomes in any future application.
A pooled record combines statistics across multiple art units under one technology center. The overall allowance rate of 80% describes past decisions on 877 disposed applications and is not a prediction applicable to any specific case. The range of 71% to 83% across art units illustrates that individual art-unit records may differ. Pooled figures are historical summaries; outcomes in any particular application depend on claim scope, prior art, and arguments presented.
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 program control and execution.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 275 decided applications with an interview and 373 without.
Primarily examines program control and execution.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 107 decided applications with an interview and 108 without.
Primarily examines neural-network / biological-model computing, and machine learning.
Methodology. This page pools every art unit in which Examiner Diem K Cao 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: 915 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.
