Examiner Trisha U Vu has allowed 223 of 308 decided applications in Computer Architecture, Software, and Information Security.
Trisha U Vu maintains a pooled allowance rate of 72% across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner's record spans three art units within this technology center. Allowance rates across these art units range from 69% to 84%, reflecting variation in the decided record across different subject areas. The 72% figure represents the share of applications that resulted in allowance among all decided applications—both allowed and abandoned—in the pooled record. This overall rate provides a factual summary of the examiner's historical output and does not function as a prediction for any pending case.
A pooled record aggregates an examiner's decided applications across multiple art units and subject areas into a single allowance percentage. This aggregate figure reflects past outcomes only and is not a prediction about the outcome of any specific application. The range shown (69% to 84%) indicates that allowance rates vary among the individual art units; the pooled rate (72%) is the combined result across all units. Reviewing both the overall rate and the per-art-unit breakdown provides context for understanding an examiner's historical record.
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.
Grounds can co-occur, so the four don't sum to 100%. The art-unit figure is the unweighted mean across examiners in the art unit; §102 and §112 carry no art-unit benchmark.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 52 decided applications with an interview and 182 without.
Primarily examines error detection, correction, and monitoring, and error-correcting coding/decoding.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 33 decided applications with an interview and 40 without.
Primarily examines interconnection and data transfer between memory, I/O, and processing units, and program control and execution.

Methodology. This page pools every art unit in which Examiner Trisha U Vu 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 July 14, 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: 308 applications.
Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

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.
