What the data says.reading this examiner

Justin T Darrow maintains a pooled allowance rate of 61% across hundreds of decided applications in Technology Center 2400. His record spans 2 art units. The allowance rate ranges from 49% to 90% across these art units, reflecting variation in the composition and outcomes of applications examined within different art-unit jurisdictions. This pooled figure represents the share of decided applications (allowed and abandoned) that issued as allowed, and does not account for pending applications.

How to read these numbers.

A pooled record aggregates allowance data across multiple art units into a single overall percentage. This aggregate describes the examiner's historical outcome distribution and is not a prediction of any specific application's disposition. Allowance rates vary by art unit due to differences in application volume, subject matter, and other case-specific factors. The range shown reflects that variation.

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 Justin T Darrow 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: 168 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.
