// READING THIS EXAMINER

What the data says.

Sen Thong Chen maintains a public record spanning two art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 158 disposed applications, 106 were allowed, yielding an allowance rate of 67%. The examiner's record across these art units ranges from 62% to 79% in allowance rates. This pooled figure aggregates activity across both art units and describes the examiner's historical record without reference to any pending matter.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines results from multiple art units into a single aggregate figure. The 67% allowance rate reflects outcomes across both art units and represents historical data only. The range of 62% to 79% indicates variation among individual art units but does not identify which art unit produced which rate. Pooled figures describe past performance and are not predictions for any specific application or art unit.

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 Sen Thong Chen 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: 158 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.
