What the data says.reading this examiner

Christopher B Robinson maintains a public record across three art units in Technology Center 2400, spanning hundreds of decided applications. His pooled allowance rate is 90%, a share of applications that were either allowed or abandoned. The allowance rate ranges from 81% to 95% across these art units, reflecting variation in disposition across the different art areas within the technology center. This pooled figure represents the aggregate outcome of his examination activity and does not constitute a prediction about any specific application.

How to read these numbers.

A pooled record aggregates an examiner's performance across multiple art units into a single allowance rate. This aggregate describes past outcomes and is a historical snapshot only—not a forecast of any individual application's path. The range of allowance rates across art units shows that outcomes vary by subject matter within the technology center. Pooled statistics are useful context for understanding an examiner's overall record but do not predict the disposition of any particular case.

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 Christopher B Robinson 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: 616 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.

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.
