// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile aggregates Titcomb's record across multiple art units in TC 2100. The pooled allowance rate of 90% represents the proportion of decided applications (allowed and abandoned combined) relative to all disposed applications—a historical aggregate. The range from 86% to 97% across art units illustrates that allowance rates vary by art unit. These statistics describe past outcomes, not predictions for individual cases.

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 William D Titcomb 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 June 25, 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: 1,063 applications.

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.
