Examiner Andrew Tsutomu Chiusano has allowed 236 of 412 decided applications (57%) in Computer Architecture, Software, and Information Security.
Andrew Tsutomu Chiusano's pooled public record spans 3 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Of 412 disposed applications, 236 were allowed, yielding an allowance rate of 57%. Across these art units, allowance rates range from 52% to 77%. This record aggregates activity across multiple art units with distinct subject matter and examiner workflow; the pooled figure represents a historical average of decided applications and does not forecast outcomes in any individual case.
A pooled record aggregates an examiner's allowance history across multiple art units. The overall allowance rate (57% here) reflects the proportion of allowed applications among all decided cases—allowed plus abandoned—across all art units combined. This aggregate figure describes past decisions and is not a prediction for any specific application. Rates vary by art unit; the range (52% to 77%) reflects this variation but does not attribute any rate to a named unit.
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.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 126 decided applications with an interview and 184 without.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 34 decided applications with an interview and 45 without.
Primarily examines general computer details, and program control and execution.
Based on 23 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Andrew Tsutomu Chiusano 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: 453 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.
