SK Hynix has signed a comprehensive license agreement with Rambus for permission to use technologies owned by the U.S. patent troll, it said Wednesday.
A patent troll earns money by buying up patents and collecting royalties without running any productive business.
Both companies agreed to withdraw all pending lawsuits as a result of the licensing agreement. SK Hynix will pay Rambus US$12 million a quarter for the next five years to use its patented semiconductor technologies. The Korean firm said now that the lawsuit is over it can resolve uncertainties and focus its energy on developing new technologies.
Rambus in 2000 sued Hynix, as it was then, for W400 billion (US$1=W1,133) in royalties. In March 2009, a California district court ruled that the Korean firm infringed Rambus' patents and ordered it to pay $400 million in compensation and usage fees. But an appeals court threw out the case in May 2011, sending it back to a lower court for review.
Samsung also signed a license agreement with Rambus in 2010, agreeing to pay the troll $700 million by 2015 and invest another $200 million.
