Any 19th century patent data with geo-referenced locations of the submitter? So, for each city or county, it lists the number of patents filed in a given year/month etc?

    You'll have to do a little work, but uspto.gov/patents-application-process/search-patents notes: "The USPTO houses full text for patents issued from 1976 to the present and PDF images for all patents from 1790 to the present."
