What the data says.reading this examiner

Angela Nguyen's public record in Technology Center 2400 spans three art units. Across hundreds of decided applications, her allowance rate is 80%. This represents the share of applications in which a final disposition of allowance or abandonment was reached, pending applications excluded. The allowance rate ranges from 75% to 100% across her art units, reflecting variation in outcomes within her pooled record. These figures describe her past record and are not predictions for any specific application.

How to read these numbers.

A pooled examiner record aggregates data across multiple art units, presenting an overall allowance rate rather than unit-specific rates. This aggregate figure summarizes historical outcomes on decided applications and provides context on the examiner's record breadth. The range indicates variation among individual art units but does not predict results in any particular case. Pooled rates are correlational summaries, not causal indicators of future prosecution outcomes.

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 Angela Nguyen 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: 697 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.
