Examiner Kenneth Tsang has allowed 37 of 58 decided applications (64%) in Computer Architecture, Software, and Information Security.
Kenneth Tsang maintains a public record across two art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 58 disposed applications, he allowed 37 and abandoned 21, yielding an allowance rate of 64%. This rate reflects the ratio of allowed to decided applications in his pooled record. The examiner's work spans art units 2137 and 2187, with figures aggregated across both units. This pooled allowance rate describes his historical performance and does not operate as a prediction for any particular application.
A pooled record aggregates statistics across multiple art units, masking potential variation within each unit. The overall allowance rate—here, 64% across 58 decided applications—is a backward-looking historical measure of allowed versus abandoned applications. Aggregate figures describe past outcomes and are not predictions about any specific application's disposition. Art-unit-level records, available separately, may show different patterns within individual units.
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 input/output (I/O) data transfer, and memory access and allocation.
Based on 45 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.

Methodology. This page pools every art unit in which Examiner Kenneth Tsang 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: 58 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.
