// READING THIS EXAMINER

What the data says.

Examiner Tong Ba Vo maintains a public record across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). The pooled allowance rate across hundreds of decided applications is 85%, representing the percentage of applications allowed or abandoned. Allowance rates vary across the examiner's art units, ranging from 76% to 96%. This range reflects the different subject matters and application characteristics examined within each art unit, and the pooled figure aggregates all decided applications into a single rate.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates all decided applications across multiple art units into one allowance-rate figure. This percentage describes the examiner's past record in the aggregate and is not a prediction of any specific application's outcome. The range across individual art units shows variation by art unit; the pooled rate represents the overall distribution and does not indicate performance in any single art unit.

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 →

// BY ART UNIT

The record, art unit by art unit.

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 & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Tong Ba Vo 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: 183 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.
