Nvidia has filed a Sherman Act complaint against Rambus in federal district court in North Carolina. The allegations appear to echo (copy?) the allegations in the FTC case I reported on recently, where the D.C. Circuit reversed the FTC’s finding of illegal monopolization by Rambus. Can Rambus file a successful motion to dismiss in this new case based on the D.C. Circuit’s decision? Very likely. Why did Nvidia file this suit? My first thought is that Nvidia was concerned about a statute of limitations problem, and this filing (even if dismissed by the District Court) will allow them to appeal and keep their claims alive during the FTC’s motion for en banc review that is pending before the D.C. Circuit, and during a possible Supreme Court appeal by the FTC. Alternatively, they may be hoping that a district court in the Fourth Circuit (or even the Fourth Circuit itself), will see things differently from the D.C. Circuit, and allow their case to proceed.
