Examiner Sheng Jen Tsai has allowed 649 of 925 decided applications (70%) in Computer Architecture, Software, and Information Security.
Sheng Jen Tsai maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning three art units. Across 925 disposed applications, the examiner allowed 649, yielding a 70% allowance rate. The allowance rate ranges from 66% to 93% across these art units, reflecting variation in outcomes by subject-matter area within TC 2100. This pooled figure aggregates the examiner's activity across all three art units and describes past decisions only.
A pooled record combines data from multiple art units into a single allowance rate. The 70% figure represents historical outcomes across all three art units combined and does not predict the result of any specific application. Variation across art units (66% to 93%) shows that outcomes differ by subject matter. Pooled statistics describe the past record; they are not forecasts for individual cases.
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.

Methodology. This page pools every art unit in which Examiner Sheng Jen 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: 963 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.
