What the data says.reading this examiner

Stephen J Houlihan maintains a pooled allowance rate of 62% across decided applications in Technology Center 2400. This rate reflects the percentage of applications that were allowed out of all decided (allowed and abandoned) applications in his public record. The examiner's work spans 1 art unit. The record encompasses hundreds of decided applications. This aggregate figure describes his past record and is not predictive of outcomes in any specific application.

How to read these numbers.

A pooled record aggregates data across all art units under an examiner's jurisdiction. The allowance rate shown here—62%—is the historical percentage of decided applications that were allowed, calculated from the combined pool of allowed and abandoned applications. Aggregate figures describe past performance and do not constitute predictions about individual cases. The breadth of art units indicates the examiner's assigned technology areas.

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 Stephen J Houlihan 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: 143 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.
