// READING THIS EXAMINER

What the data says.

Examiner Hexing Liu has a pooled allowance rate of 66% across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). This rate reflects the share of applications that were allowed among all decided (allowed and abandoned) applications, pooled across the examiner's 2 art units. The public record spans art units 2167 and 2169 within TC 2100. The allowance rate is a historical measure of past disposition outcomes and does not predict the outcome of any particular application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates data across multiple art units, presenting a combined allowance rate rather than unit-by-unit breakdowns. The 66% figure describes past decided applications as a whole and reflects historical outcomes only. Pooled rates are correlational measures of an examiner's record and are not predictions of any specific application's outcome. Per-art-unit detail, where available, appears separately.

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 Hexing Liu 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: 216 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.
