What the data says.

Examiner Weilun Lo maintains a public record of 79 disposed applications across one art unit in Technology Center 2100 (Computer Architecture, Software, and Information Security). Of those decided applications, 2 were allowed and 77 were abandoned, yielding an allowance rate of 3%.

The record does not include applications still pending.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates the examiner's work across all art units and reflects historical dispositions only. The 3% allowance rate describes what occurred in the past 79 decided cases and is not a prediction of the outcome in any new or pending application. Pooled figures mask variation across individual art units; a separate section on this page shows per-art-unit detail. Aggregate statistics describe the record, not the future.

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 Weilun Lo 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: 79 applications.

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.
