What the data says.reading this examiner

Kevin S Mai has a pooled allowance rate of 31% across hundreds of decided applications in Technology Center 2400. His record spans 5 art units. The allowance rate—the percentage of decided applications (allowed and abandoned) that were allowed—varies across these art units, ranging from 21% to 63%. This range reflects the different subject matter and application characteristics within each art unit. The pooled figure represents an aggregate of his examination record across all five art units combined and does not predict the outcome of any specific application.

How to read these numbers.

This record aggregates examination results across multiple art units within TC 2400. A pooled allowance rate describes the examiner's historical performance across all art units combined and reflects the mix of allowed and abandoned applications decided. The overall percentage is a backward-looking summary and is not a prediction of any specific application. Individual art units may show different allowance rates; those figures appear separately. Pooled data serves as context for understanding the breadth and variation in the examiner's record.

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 Kevin S Mai 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: 497 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.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
