In poldham/drones: A Patent Dataset for Drone Technology

#' @title patsnap family
#' @description A set of 8,728 priority documents with simple and INPADOC extended family data for use in examining the difference between patent family sizes under different definitions. The table is derived from a search using \href{http://www.patsnap.com/}{Patsnap} for documents containing the term drone or drones in the patent claims. Note that number formats for Patsnap differ from those used by Clarivate Analytics for the same data.
#' @details Patsnap data uses number formats including "/" and will not harmonise with data from Clarivate Analytics DWPI in this package without additional work.
#' @usage data("patsnap_family")
