// READING THIS EXAMINER

What the data says.

Examiner Kuen S Lu maintains a public record across five art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 1,373 disposed applications, the examiner's allowance rate is 87%. This figure represents the share of decided applications—those allowed or abandoned—and excludes pending matters. The allowance rate ranges from 80% to 98% across the examined art units, reflecting variation in outcomes by art-unit subject matter.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates outcomes across multiple art units and reflects historical performance, not a prediction for any individual application. The allowance rate is computed from disposed applications only and does not account for pending filings. The range across art units shows that outcomes differ by technology area. This examiner's record spans five art units, each with distinct subject matter within TC 2100.

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 Kuen S Lu 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: 1,402 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.
