What the data says.

Clifford H Knoll maintains a public record across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 478 disposed applications, the examiner allowed 396 and abandoned 82, yielding an allowance rate of 83%. The allowance rate ranges from 73% to 85% across the examiner's art units. This pooled figure aggregates outcomes across different subject areas within TC 2100 and reflects decided applications only; pending matters are excluded from the calculation.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines data from multiple art units, masking variation among them. The aggregate allowance rate—here, 83%—describes past outcomes across all units combined and is not predictive of any single application's outcome. The stated range (73% to 85%) indicates that allowance rates differ among the examiner's art units. This context is essential when interpreting overall statistics; examination results vary by specific art unit and application facts.

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 →
