What the data says.reading this examiner

Guang W Li maintains a pooled allowance rate of 79% across hundreds of decided applications in Technology Center 2400. The examiner's record spans 2 art units. Allowance rates across these art units range from 31% to 82%. The pooled figure of 79% represents the percentage of applications that were allowed among all decided applications (allowed and abandoned combined) across the examiner's art-unit assignments. This aggregate rate describes the examiner's historical record and does not constitute a prediction for any specific pending application.

How to read these numbers.

This pooled record aggregates the examiner's performance across multiple art units within TC 2400. The overall allowance rate reflects decided applications only—those allowed or abandoned—and excludes pending matters. Because the record spans different art units, the aggregate figure masks variation: the range shown (31% to 82%) indicates that allowance rates differ among individual art units. Pooled data describes past outcomes and is not a forecast of any particular application's disposition.

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 Guang W Li 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: 728 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.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes. Where this page compares an examiner's allowance rate to an art-unit average, that comparison is a factual description of the public record, not a characterization of any individual examiner's conduct or competence.
