What the data says.reading this examiner

Ngoc K Vu maintains a public record in Technology Center 2400 across one art unit. The examiner's pooled allowance rate is 72%, calculated over hundreds of decided applications (those allowed or abandoned, with pending applications excluded from the calculation). This allowance rate reflects the proportion of applications with final dispositions in the examiner's record. The pooled figure represents the examiner's aggregate performance across the art units in which they work and serves as a historical reference point.

How to read these numbers.

A pooled record aggregates an examiner's performance across multiple art units into a single allowance-rate figure. This aggregate describes past outcomes and does not constitute a prediction about any specific application. Different art units within the technology center may have different examination patterns. The pooled rate is a historical statistic; individual application outcomes depend on claim scope, prior art, and examiner-specific determinations in each case.

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 Ngoc K Vu 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: 294 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.
