Legal/Intellectual Property Question—I have used the search engines (WIPO and USPTO) listed below to research potential biotech investments. Imclone has a number of interesting patents that can be found by searching the WIPO site. Question? What is the significance of a patent being listed @WIPO? @USPTO?
