These include patents 7,336,260, 8,749,507, 9,430,042, 9,116,546, 10,627,907, 10,665,067, and 11,175,738.
Additionally, Immersion is pursuing damages and royalties.
Valve now faces a challenging legal battle, given the extensive precedent set by other tech giants.
After engaging in legal disputes, companies such as Sony and Microsoft opted to license Immersion’s patent portfolio.
Similarly, Apple, Google, Motorola, and Fitbit also settled and obtained licenses.
Interestingly, Nintendo, which utilizes a different form of rumble technology, managed to evade the lawsuit.
This could be because Nintendo developed its own Rumble Pak tech for the Nintendo 64.
However, even Nintendo now licenses Immersion’s technology.
It is worth noting that Immersion did not include Valve’s discontinued Steam Controller in its lawsuit.
Instead, the focus is on the Steam Deck, which has achieved considerable success in terms of sales.
The Steam Deck has also garnered positive reviews from critics and gamers alike.
