What the data says.

James T Tsai has a pooled allowance rate of 65% across 320 disposed applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His public record spans three art units. The allowance rate ranges from 53% to 90% across these art units, reflecting variation in outcomes within TC 2100. Of his 364 total applications, 207 were allowed and 113 were abandoned. This pooled figure aggregates his work across multiple art units and describes his historical record without predicting outcomes in any specific application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines an examiner's statistics across multiple art units into a single aggregate profile. The overall allowance rate reflects the percentage of decided cases (allowed plus abandoned) across all art units combined. The range shows variation among the individual units but does not identify which rate belongs to which unit. These pooled figures describe past outcomes and are not predictions for any specific 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 James T 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: 364 applications.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
