In addition to filing a patent infringement lawsuit against Nvidia back in July, technology licensing company Rambus has seen it fit to ask the International Trade Commission for an import ban of graphics cards that use Nvidia chips – which includes products from Asustek, Gigabyte, MSI, EVGA and others.

The company alleges that Nvidia and its partners are infringing on nine patents covering DDR, DDR2, DDR3, LPDDR, GDDR, GDDR2, and GDDR3 memory controllers. The ITC is expected to decide whether to initiate an investigation under this complaint within 30 days, according to Rambus, which has a long history of lawsuits against companies relying on memory technology – many have gone to their favor and several against, so we’ll have to wait and see where this goes.
