What the data says.reading this examiner

Lin Liu maintains a pooled allowance rate of 54% across hundreds of decided applications in Technology Center 2400. This rate reflects the share of applications that issued as allowed out of all decided applications (allowed and abandoned combined) across the examiner's record. The examiner works within 1 art unit. The public record shows allowance rates as historical data describing past decisions; they do not predict outcomes in any specific pending application.

How to read these numbers.

This pooled record aggregates Lin Liu's decisions across all art units under his jurisdiction. Aggregate allowance rates describe the examiner's historical record and reflect the distribution of allowed and abandoned applications decided over time. Such aggregate figures are correlational summaries of past outcomes and are not predictions about any particular application. Individual art units may show different patterns; detailed per-art-unit data 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 →

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Lin Liu has a public record within Technology Center 2400. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 22, 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: 137 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.
