What the data says.reading this examiner

Obafemi Oludayo Sosanya holds a public record spanning 2 art units within Technology Center 2400. Across hundreds of decided applications, the examiner's pooled allowance rate is 73%. This aggregate figure represents the share of applications in the decided set (allowed and abandoned combined) across all art units under review. Allowance rates vary among the examiner's art units, ranging from 65% to 93%. The pooled rate reflects the combined record and does not predict outcomes in any individual application.

How to read these numbers.

This record aggregates the examiner's work across multiple art units. The pooled allowance rate describes the historical record—the percentage of decided applications that were allowed—and is calculated from all art units combined. Aggregate figures summarize past disposition patterns and are not predictions about specific applications. Art-unit-level detail appears separately; this narrative covers the examiner's overall profile only.

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 Obafemi Oludayo Sosanya 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: 511 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.
