AASTRA did not pay $ 200M, My bad. Not sure what they paid. Microsoft paid $ 200M in 2007 for a different patent infringement.

Now what: VirnetX isn't a stranger to suing larger corporations over patent rights, as it successfully sued Microsoft (Nasdaq: MSFT ) in 2007 after alleging that Microsoft Office Communicator and Microsoft Office Meeting violated two of its patents. VirnetX later settled with Microsoft for $200 million. It's not unreasonable to think VirnetX isn't in line to win another case, but I also wouldn't bet the farm on a patent infringement case. At a forward P/E of 82, there are far better values to be had in the technology space than VirnetX.
