// READING THIS EXAMINER

What the data says.

Em N Trieu maintains a public record across 2 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Of 107 total applications on record, 68 have been decided (allowed or abandoned). Among those decided applications, 35 were allowed, yielding an allowance rate of 51%. The remaining 33 decided applications were abandoned. This pooled record aggregates the examiner's work across art units 2126 and 2128 and represents dispositions on file through the most recent public data update.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's decisions across multiple art units, presenting overall statistics rather than art-unit-specific breakdowns. The allowance rate (51%) describes the historical share of decided applications that were allowed and is calculated only from disposed applications, excluding any pending filings. Aggregate figures describe past outcomes and do not constitute predictions about 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 →

// BY ART UNIT

The record, art unit by art unit.

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.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Em N Trieu 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: 107 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.
