What the data says.reading this examiner

Susan X Li maintains a pooled allowance rate of 65% across dozens of decided applications in Technology Center 2400. Her public record spans a single art unit. The allowance rate reflects the share of her decided applications—those allowed or abandoned—that resulted in allowance. This aggregate figure covers her entire decided portfolio within the technology center and represents past outcomes only, not a prediction of any specific application's disposition.

How to read these numbers.

A pooled record aggregates decisions across all art units assigned to an examiner. The allowance rate shown is a historical summary of allowed applications as a percentage of all decided applications in that pool. This aggregate figure describes past outcomes and does not forecast the result of any individual case. Applicants review such records to understand an examiner's historical pattern, keeping in mind that individual applications may vary.

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 Susan X 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: 77 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.
