What the data says.reading this examiner

Examiner Zhubing Ren maintains a public record in Technology Center 2400, covering art unit 2483. Across hundreds of decided applications, the examiner's allowance rate is 72%. This figure represents the share of applications that were allowed among all decided applications (allowed and abandoned). The record reflects the examiner's decisions on applications in the assigned art unit within the technology center. The allowance rate is based on historical outcomes and describes past application decisions, not future results.

How to read these numbers.

A pooled record aggregates decisions across all art units assigned to an examiner. The allowance rate shown here—72%—describes the aggregate historical outcome across hundreds of decided applications. This figure represents past decisions and is not a prediction of any specific application's outcome. Individual art units may show different rates. Aggregate statistics describe what occurred in the examiner's prior decided cases and provide context for the examiner's overall record, not guidance on how any particular application will be examined.

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 Zhubing Ren 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: 415 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.
