// READING THIS EXAMINER

What the data says.

Huawen A Peng maintains a record across 3 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner's pooled allowance rate is 83% across hundreds of decided applications. This rate reflects the share of applications allowed among all decided (allowed and abandoned) filings in the examiner's record. The allowance rate ranges from 75% to 96% across the examiner's art units, indicating variation in outcomes by subject matter within the technology center. This pooled figure represents an aggregate record and does not constitute a prediction for any particular application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates the examiner's decisions across multiple art units within TC 2100. A pooled allowance rate describes historical outcomes across decided applications and reflects past examination patterns. The range from lowest to highest art-unit rate indicates that outcomes vary by subject matter. Pooled statistics are descriptive of the examiner's record and are not predictions about any specific application or prosecution path.

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 Huawen A Peng 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: 769 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.
