// READING THIS EXAMINER

What the data says.

Fenyang A Stewart has a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning two art units. Across 36 disposed applications, the examiner allowed 12 and abandoned 24, yielding an allowance rate of 33% over the decided count. This pooled figure represents the examiner's historical record across both art units combined and does not constitute a prediction for any individual application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This record is pooled across two art units within TC 2100, meaning it aggregates different technology areas and examination patterns. The 33% allowance rate reflects the overall past record across both units combined. Pooled figures describe historical performance, not outcomes for any specific pending application. Individual art units may have distinct profiles; see the separate per-art-unit section for granular detail.

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 Fenyang A Stewart 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: 36 applications.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
