NTP, the company that won a patent case against RIM over wireless email technology in 2006, has filed similar suits against Apple, Google, Motorola, Microsoft, HTC and LG.
The suits, covering eight wireless email patents, were filed in the same federal court in Virginia where its long-running case against RIM was heard, WSJ.com reports.
NTP agreed a $612 million (€486.1 million) settlement from RIM in 2006, after winning the right to launch an injunction that could have effectively closed down RIM’s US business, FT.com reported.
NTP says the trial judge case had determined that the company was entitled to royalties of 5.7% of RIM’s hardware sales.
The trial resulted in RIM, Nokia, Visto, and Good Technology agreeing licensing deals for NTP’s email technology.
