资源简介：
HistPat International provides the geography of historical patents granted to foreigns by the United States Patent and Trademark Office (USPTO) from 1836 to 1975. This historical dataset is constructed using digitalized records of original patent documents that are publicly available. HistPat can be used in different disciplines ranging from geography, economics, history, network science, and science and technology studies. Additionally, it can easily be merged with post-1975 USPTO digital patent data to extend it until today.
