// READING THIS EXAMINER

What the data says.

Charles Edward Lu maintains a 62% allowance rate across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His public record spans two art units within TC 2100. The allowance rate reflects the share of applications that were allowed among all decided applications—those either allowed or abandoned—in his pooled record. This figure describes past dispositions and does not predict outcomes for any particular application. The data aggregates his work across both art units he covers.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record combines all decided applications across the examiner's two art units in TC 2100. Aggregate figures describe historical dispositions, not predictions for individual cases. A pooled allowance rate reflects the proportion of allowed applications among all decided filings and varies by art unit, subject matter, and claim complexity. The data presented here is correlational; it shows what occurred in past applications but does not indicate what will occur in any specific prosecution.

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

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Charles Edward 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 July 14, 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: 447 applications.

Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

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.
