// READING THIS EXAMINER

What the data says.

Examiner Huawen A Peng has a pooled allowance rate of 83% across 748 decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner's record spans three art units (2157, 2158, 2169). Among these art units, allowance rates range from 75% to 96%, reflecting variation in outcomes across different subject-matter groups within TC 2100. Of 769 total applications on record, 621 were allowed and 127 were abandoned. This pooled figure aggregates outcomes across all three art units and describes the examiner's past record only.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines allowance data from multiple art units into a single aggregate figure. The 83% rate reflects decided applications across all three art units combined and describes historical outcomes, not a prediction for any specific application. Individual art units within TC 2100 show different allowance rates (ranging 75%–96%), which means outcomes vary by subject matter. The pooled figure is useful context for understanding the examiner's overall record but does not forecast the disposition of any particular filing.

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 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 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: 769 applications.
