What the data says.reading this examiner

Michael C Lai maintains a pooled allowance rate of 85% across hundreds of decided applications in Technology Center 2400. His public record spans a single art unit. The allowance rate represents the share of applications that were allowed among all decided applications—those allowed and abandoned—in his record. This figure is based on applications that reached a final disposition and does not include pending applications. The pooled rate aggregates his complete decided caseload across all art units in which he has examined.

How to read these numbers.

A pooled record aggregates an examiner's data across all art units in Technology Center 2400. The overall allowance rate describes past outcomes and is not a prediction for any specific application. Aggregate figures mask variation by art unit and do not forecast prosecution results. Individual art-unit data may reveal different rates. A pooled allowance rate is a historical reference point and reflects only decided applications, excluding those still pending.

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 →

    His public record spans one art unit within Technology Center 2400.
  • What does the pooled allowance rate tell me about my application?
    The pooled allowance rate describes past outcomes across hundreds of decided applications and is not a prediction of any specific application's outcome. Individual art-unit rates may differ from the pooled figure.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Michael C Lai 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: 556 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.
