Examiner Leah M Feitl has allowed 22 of 87 decided applications (25%) in Computer Architecture, Software, and Information Security.
Leah M Feitl maintains a public record spanning 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 87 disposed applications, the examiner's allowance rate is 25%, meaning that of applications decided (allowed or abandoned), 25% resulted in allowance. The allowance rate ranges from 21% to 30% across these art units. The record reflects 22 allowed applications and 65 abandoned applications. A total of 132 applications appear in the examiner's overall portfolio.
This profile aggregates the examiner's record across multiple art units in TC 2100. The pooled allowance rate of 25% describes the past record and is calculated from decided applications only—pending cases are excluded. The range of 21% to 30% reflects variation across the individual art units but does not identify which rate belongs to which unit. Aggregate figures describe historical outcomes and are not predictions about any specific pending application.
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 →
Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.
Primarily examines artificial-intelligence and machine-learning methods.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 25 decided applications with an interview and 19 without.
Primarily examines neural-network / biological-model computing, and machine learning.
Based on 43 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Leah M Feitl 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: 132 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.
