What the data says.reading this examiner

Examiner Trang U Tran maintains a public record in Technology Center 2400 spanning one art unit. Across more than a thousand decided applications, the examiner's allowance rate is 82%. This rate reflects the share of applications that were allowed among all decided applications (allowed and abandoned combined), excluding pending matters. The pooled allowance rate represents the examiner's historical record across the art units in which decisions have been rendered.

How to read these numbers.

A pooled record aggregates data across multiple art units into a single overall figure. The allowance rate shown here is a historical average of past decisions and does not predict the outcome of any specific application. Pooled figures describe what has occurred; they are correlational summaries, not causal indicators of how any individual case will be examined or decided.

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 Trang U Tran has a public record within Technology Center 2400. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 22, 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: 1,045 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.

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.
