It looks like a number of MMO game publishers are being hit with lawsuits from a company that claims they are all violating patent agreements. Boston.com reports that their local MMO company Turbine along with Sony, Activision Blizzard, NCsoft and Jagex have all been hit with such lawsuits by Paltalk Holdings.

Paltalk owns the rights to two patents that describe technology for sharing data with lots of connected computers. They have already settled a case with Microsoft who Paltalk accused of using their patents in the multiplayer potion of Microsoft's Halo series. So far there's been no reaction yet from any of the MMO publishers named in the lawsuit.
