What the data says.reading this examiner

Examiner Luu T Pham maintains a public record across 2 art units in Technology Center 2400, spanning hundreds of decided applications. The pooled allowance rate stands at 50%, representing the share of allowed applications among all decided (allowed and abandoned) cases. The allowance rate ranges from 23% to 55% across these art units, reflecting variation in outcomes by art unit. This aggregate figure describes the examiner's historical record and is not a prediction of any specific application's outcome.

How to read these numbers.

A pooled record aggregates data across multiple art units, producing a single overall allowance rate that masks differences among individual units. The 50% figure represents past outcomes across decided applications and does not predict how any particular application will be examined. Allowance rates vary by art unit; the range from 23% to 55% indicates that outcomes differ depending on the specific art unit handling an application. Aggregate statistics describe historical performance, not future results.

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 Luu T Pham 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: 177 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.
