What the data says.reading this examiner

Joel Mesa maintains a public record across 1 art unit in Technology Center 2400. Across hundreds of decided applications, his allowance rate is 55%. This figure represents the share of applications in the decided pool (allowed and abandoned combined) that were allowed; pending applications are excluded from this calculation. The allowance rate is a historical statistic of outcomes already reached and does not characterize any specific application or predict outcomes on future filings.

How to read these numbers.

This profile aggregates Mesa's record across all his art units into a single pooled allowance rate. The 55% figure describes past decided applications only and reflects outcomes already closed. Pooled rates combine different art units and subject areas, so they describe the examiner's overall historical pattern rather than predict any single application's path. Each application is examined individually on its merits.

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 Joel Mesa 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: 385 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.
