Patent company NTP has filed six patent infringement lawsuits against major smartphone makers including Apple, Google, Microsoft, LG, HTC and Motorola.
The lawsuits allege that the companies used NTP's e-mail technology without correct licensing.
NTP was founded by inventor Thomas Campana to hold the 50 technology patents developed by him over his career. The company generates revenue, not from the manufacture of its own products, but by the money it generates from licensing its patents.
Earlier, BalckBerry maker Research in Motion had to pay $612.5 million to NTP to settle a patent infringement lawsuit and is currently in the middle of lawsuits against AT&T, Deutsche Telekom, T-Mobile USA, Sprint Nextel and Verizon Wireless for patent infringements.
In a statement, Donald Stout, the company co-founder, said: “Use of NTP's intellectual property without a license is just plain unfair to NTP and its licensees. Unfortunately, litigation is our only means of ensuring the inventor of the fundamental technology on which wireless e-mail is based.”
