These patent infringement cases seem to be everywhere these days. This is a huge one though, as Hynix has been ordered to pay Rambus $306 Million. While that's a lot of cash, Rambus could be looking at even more money from others as a result from the court ruling.
"The verdict, though, could prompt Rambus to file even more lawsuits. PC makers and others who incorporated DDR into their products are potentially liable. Graphics chipmakers, which insert a type of memory called GDDR into their products, could also get a call from the Rambus legal department. Some have estimated that the royalties and damages from the patents could total to about $1 billion or more."
