What the data says.

Examiner Lan Dai T Truong maintains a public record across three art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 53 disposed applications, the examiner has allowed 20 and abandoned 33, yielding an allowance rate of 38%. This rate reflects decisions made on the full set of applications that have reached final disposition in the examiner's pooled caseload. The record spans art units 2132, 2143, and 2152, aggregating activity across multiple areas of the technology center's subject matter.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's decisions across multiple art units into a single allowance figure. This aggregate rate describes the examiner's past decisions and reflects historical outcomes across different technology areas. Aggregate statistics do not predict outcomes on any individual application. Each application's outcome depends on claim scope, prior art, and examiner assessment of patentability under applicable law. Pooled data provides a general baseline for historical allowance frequency only.

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

  • What does the pooled allowance rate mean for my application?
    The pooled rate is a historical summary and does not predict any specific application's outcome. Each application is evaluated individually based on the claims, prior art, and applicable patentability law.
  • Why are applications pooled across multiple art units?
    Examiners often work across multiple art units. Pooling aggregates their decisions into a single record for statistical transparency. Per-art-unit breakdowns appear in a separate detailed section.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Lan Dai T Truong 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: 53 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.
