What the data says.

David Hoang Tran maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) across 2 art units. His pooled allowance rate stands at 13% across a small number of decided applications. This rate reflects the share of applications in his record that were allowed, measured among all decided applications (those allowed or abandoned, with pending applications excluded). The 13% figure represents his aggregate record and does not vary by individual art unit.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates decided applications across multiple art units within TC 2100. The allowance rate of 13% describes the examiner's past record and is a historical measure only. Aggregate figures do not constitute a prediction for any specific application and mask variation among individual art units. Per-art-unit data, where available separately, may differ from the pooled rate. All figures are correlational, not causal.

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 David Hoang Tran 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: 59 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.
