// READING THIS EXAMINER

What the data says.

Crystal Joy Barnes-Bullock maintains a public record across 7 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across more than a thousand decided applications pooled over these art units, her allowance rate is 88%. The allowance rate ranges from 85% to 94% across these art units, reflecting variation in the specific subject matter and application characteristics within each unit. This pooled figure represents applications that were allowed or abandoned; pending applications are excluded from the calculation.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's performance across multiple art units, smoothing unit-by-unit variation into a single overall rate. The 88% allowance rate describes historical decided applications and reflects the examiner's pattern across TC 2100 generally. It is not a prediction of any specific application's outcome. The range of 85% to 94% shows that individual art units within this examiner's portfolio exhibit different allowance rates; a separate section of this page details those unit-level figures.

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 →

// BY ART UNIT

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Crystal Joy Barnes-Bullock has a public record within Technology Center 2100. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 14, 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: 1,209 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.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes. Where this page compares an examiner's allowance rate to an art-unit average, that comparison is a factual description of the public record, not a characterization of any individual examiner's conduct or competence.
