Patent holding company NTP, which received a $612.5 million settlement from BlackBerry maker Research In Motion in a patent infringement case, has filed patent lawsuits against six makers of smartphones or related software, including Apple and Google.
NTP also filed patent lawsuits Thursday against Microsoft, LG Electronics, HTC and Motorola in US District Court for the Eastern District of Virginia, the company announced. NTP accused the six companies of violating eight patents related to the delivery of email over wireless communications systems.
"Use of NTP's intellectual property without a licence is just plain unfair to NTP and its licensees," Donald Stout, NTP's co-founder, said in a statement. "Unfortunately, litigation is our only means of ensuring the inventor of the fundamental technology on which wireless email is based, Tom Campana, and NTP shareholders are recognised, and are fairly and reasonably compensated for their innovative work and investment."
In addition to RIM, NTP has licensing agreements with Good Technology, Nokia and Visto, the company said in a press release.
Representatives of HTC and Motorola had no comment on the lawsuits. Representatives of the other four companies facing lawsuits didn't have immediate comments or didn't immediately respond to a request for comments.
NTP has sued several other companies for patent infringement, including Verizon Communications, AT&T and Sprint Nextel in 2007.
