No, you don't understand patent assignments (see below). A patent assignment can get complicated. It can be the transfer of a your entire ownership interest or a percentage of your ownership interest in the patent. www.the-business-of-patents.com/patent-assignment.html REVO did not assign total ownership of its patents to Eyetalk365 it was only a partial assignment, so that Eyetalk could pursue patent infringers. If Ross Helfer and Eyetalk365 own the REVO patents where are the documents stating this on USPTO.com???
