Examiner Daniel D Tsui has allowed 657 of 720 decided applications (91%) in Computer Architecture, Software, and Information Security.
Daniel D Tsui has a public record of 741 total applications across three art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Of 720 disposed applications, 657 were allowed, yielding an overall allowance rate of 91%. The examiner's allowance rate varies across art units, ranging from 55% to 95%. This pooled figure aggregates outcomes across all three art units and describes the examiner's historical record without predicting outcomes in any specific case.
A pooled record combines outcomes across multiple art units into a single aggregate rate. The 91% allowance rate reflects past decisions across all three units. This aggregate is a historical summary and is not a prediction of any specific application's outcome. Individual art units may differ from the pooled rate. Review the separate per-unit section to see how rates vary within TC 2100.
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.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 144 decided applications with an interview and 474 without.
Primarily examines data-processing methods for specific functions, and processing data by its order or content.
Based on 37 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Daniel D Tsui 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: 741 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.
