Silicon Valley memory technologies firm RAMBUS has filed an injunction against NVIDIA with the US International Trade Commission containing allegations of copyright infringement.

The complaint claims that NVIDIA, in addition to 16 other companies, are violating 17 RAMBUS patents related to the memory controller which allows VRAM to communicate with other components of the GPU.

Rambus General Counsel Tom Lavelle indicated that NVIDIA and RAMBUS negotiated the current dispute for six years without resolution. “We believe this action is necessary given Nvidia’s continued willful infringement of our patents,” he said in press release last Thursday.

The US ITC is expected to determine if the filing is worth investigation within thirty days.
