What the data says.

Henry Tsai has disposed of 173 applications across three art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Of these decided applications, 120 were allowed, yielding an allowance rate of 69%. The public record spans art units 2181, 2183, and 2184. Allowance rates across these art units range from 14% to 89%, reflecting variation in the examiner's decisions within TC 2100.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates three separate art units within TC 2100. The 69% allowance rate describes the examiner's past decisions across all three units combined and does not represent a prediction for any individual application. Pooled figures mask variation; the range of 14% to 89% across art units shows that outcomes differ significantly depending on the specific art unit assigned to an application.

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 →

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Henry Tsai 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: 174 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.
