Wavestar Communications Systems LLC has sued Fortinet (2:16-cv-01482) over a single patent (8,391,915) generally related to wireless networks with overlapping cells. The NPE accuses of infringement Fortinet products and services that determine when a mobile device moves out of one cell into another, including Fortinet’s Infrastructure Wi-Fi Suite, which came to Fortinet through its July 2015 acquisition of Meru Networks. Wavestar’s is one of eight litigation campaigns, in disparate technical fields, initiated by entities managed by Erik Stamell, now the president of NPE Equitable IP Corporation, since November 2015.
