What the data says.reading this examiner

Timothy John Sowa maintains a pooled allowance rate of 56% across hundreds of decided applications in Technology Center 2400. His public record spans 2 art units. The allowance rate—the percentage of decided applications (allowed and abandoned combined, excluding pending applications)—reflects his record pooled across all art units in which he has examined. Allowance rates across his individual art units range from 50% to 80%. This range indicates variation in outcomes by art unit, though the pooled figure of 56% represents the aggregate of his examination record across the technology center.

How to read these numbers.

A pooled allowance rate aggregates an examiner's record across multiple art units and represents past outcomes on decided applications only. The range (50% to 80%) shows that individual art units may differ from the pooled rate of 56%. These figures describe the examiner's historical record and are not predictions for any specific application. Art unit, claim scope, prior art, and other application-specific factors affect individual outcomes.

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 Timothy John Sowa 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: 182 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.
