What the data says.reading this examiner

Examiner Rong Le maintains a pooled allowance rate of 70% across decided applications in Technology Center 2400. The examiner's public record spans 2 art units, with allowance rates that range from 56% to 80% across these art units. This record is drawn from hundreds of decided applications. The allowance rate reflects the share of applications that were allowed among all decided applications (allowed and abandoned combined); pending applications are excluded from this calculation.

How to read these numbers.

This pooled record aggregates the examiner's work across multiple art units within TC 2400. The 70% allowance rate is a historical summary of past decisions and does not serve as a prediction for any specific pending application. Allowance rates vary by art unit, as shown in the range. Applicants may review individual art-unit statistics separately to understand variation in the examiner's record within different subject areas.

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 Rong Le 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: 517 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.
