Apple is well known for suing over unlicensed use of their patented technology. So it’s always fun to see the tables turned. Last time it was the Swiss clock design used in iOS 6. This time a federal jury has sided with VirnetX and ordered Apple to pay $368 million in damages.
VirnetX Holdings Inc are in possession of a patent that covers the use of a domain name service to setup virtual private networks, through which a user could interact with another user or access corporate files for example. In the over all picture, this may be a small part of the FaceTime protocol, if would still constitute a violation of the patent.
Interestingly, back in 2010 VirnetX successfully sued Microsoft for $200 million for infringement on the same patent.
