What the data says.reading this examiner

John W Isom maintains a public record across one art unit in Technology Center 2400. His pooled allowance rate across dozens of decided applications is 18%, representing the share of applications that issued as allowed among all decided (allowed and abandoned) applications in his record. This figure reflects past outcomes on applications that reached a final disposition and does not project results on any pending or future case.

How to read these numbers.

This pooled record aggregates all decided applications across the examiner's art units. The allowance rate describes historical outcomes only—what percentage of applications that were finally decided resulted in allowance. Pooled figures represent a cross-unit average and are not predictive of any individual application's outcome. Different art units may have distinct examination patterns.

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 John W Isom 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: 94 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.
