What the data says.reading this examiner

Kenneth R Coulter maintains an 88% allowance rate across hundreds of decided applications in Technology Center 2400. His record spans three art units: 2441, 2445, and 2454. The allowance rate ranges from 71% to 90% across these art units, reflecting variation in the decided application outcomes within each unit. This pooled figure represents applications that have been allowed or abandoned; pending applications are excluded from the calculation. The public record reflects historical outcomes only and does not characterize performance within any specific art unit.

How to read these numbers.

A pooled record aggregates allowance rates across multiple art units into a single overall figure. This aggregated rate describes past outcomes across all units combined and reflects the examiner's historical record. The range (minimum to maximum allowance rate per art unit) shows variation among individual units but does not predict the outcome of any specific application. Pooled statistics are correlational summaries of past decisions, not predictors of future prosecution.

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 Kenneth R Coulter 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: 1,000 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.
