from the article:
While Valve’s hardware uses a different form of rumble than the ones that Sony and co. got sued for back in the day — linear resonant actuators (LRA), rather than an eccentrically swinging weight on a shaft — that didn’t stop Nintendo from signing an agreement with Immersion to bring its technology to the Switch, which uses LRAs as well. So does Sony’s DualSense, for that matter.
immersion didn't invent LRAs. their claim is that the use of LRAs vs swinging weights is irrelevant; that any vibration haptics via any means would constitute a patent infringement.
