This globe represents half of all patents in the US - those registered to
foreign holders. Countries with more than 1000 patents registered in
the US are indicated by name, with the point size of the representative
text scaled according to the square root of the total number of US
patents held. Japan accounts for roughly one third of foreign-held US
patents, followed by Germany, the UK, and France. Were the number
of domestically held US patents to be indicated according to this logic,
the entire surface of the globe would be covered.
