Examiner Charles J Cai has allowed 315 of 371 decided applications (85%) in Computer Architecture, Software, and Information Security.
Charles J Cai maintains a public record across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 410 total applications, 315 have been allowed and 56 abandoned, yielding 371 disposed applications. The allowance rate stands at 85% of decided applications. This pooled figure aggregates the examiner's work across both art units and reflects the proportion of allowed to abandoned applications in the completed record, without regard to pending filings.
A pooled record combines data from multiple art units into a single aggregate. The figures presented—allowance rate, art-unit count, and application counts—describe the examiner's historical output across all assigned units. These aggregate statistics characterize the past record only and are not predictions of the outcome on any individual application. Different art units may exhibit different patterns; pooled data masks that 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 control or regulating systems, and electric power networks.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 230 decided applications with an interview and 138 without.
Primarily examines control or regulating systems.
Based on 3 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Charles J Cai 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: 410 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.
