// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates the examiner's work across a single art unit within TC 2100. The allowance rate (57%) describes historical dispositions—allowed versus abandoned applications—and is not a prediction of any specific application's outcome. Pooled rates combine different subject areas and prosecution patterns, so they serve as background context on the examiner's overall record rather than indicators of how any particular case will be examined or decided.

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 Shen C Shiau has a public record within Technology Center 2100.
