Immersion Sues Valve Over Steam Deck and Index Haptic Technology
Immersion Corporation has filed a lawsuit against Valve over rumble haptic technology found in the Steam Deck and Valve Index, citing seven patents dating back to as early as 2002. Immersion has a history of suing companies it claims have infringed on its rumble tech patents, with both Microsoft and Sony licensing tech from Immersion's patent portfolio. Immersion seeks damages, royalties, plus an injunction against Valve “from deploying, operating, maintaining, testing, and using the Accused Handheld Instrumentalities and Accused VR Instrumentalities."
