// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates data across multiple art units within TC 2100. The 90% allowance rate represents the share of allowed applications among all decided cases (allowed plus abandoned). Pooled figures describe the examiner's historical record and do not predict the result of any particular application. Per-art-unit detail, where available, appears separately and may differ from the pooled aggregate.

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 Sumati Lefkowitz 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: 40 applications.
