Immersion Corporation have a history of taking on companies and winning, with Valve being the latest in the firing line over Immersion's patents. The patents involved are 7,336,260, 8,749,507, 9,430,042, 9,116,546, 10,627,907, 10,665,067, and 11,175,738.
They're pretty notorious for this going after Xiaomi, Meta (Facebook), Sony, Microsoft and more in the past. Most companies just seem to partner up with them now and license their stuff.
From the press release:
“Immersion and its employees have worked diligently for almost 30 years to invent innovative haptic technologies that allow people to use their sense of touch to engage with products and experience the digital world around them. Our intellectual property is relevant to many of the most important and cutting-edge ways in which haptic technology is and can be deployed, and, in the case of AR/VR experiences, haptics is crucial to an immersive user experience,” said Eric Singer, Chairman and CEO.
“While we are pleased to see that Valve recognizes the value of haptics and has adopted our haptic technology in its handheld video game and AR/VR systems as part of its effort to generate revenue streams through the sales of hardware, games and other virtual assets, and advertisements, it is important for us to protect our business against infringement of our intellectual property to preserve the investments that we have made in our technology,” added Mr. Singer. “We must ensure that our intellectual property is recognized as a necessary feature in the handheld video game and emerging AR/VR markets, even when litigation becomes necessary.”
I have reached out to Valve Press, to see if they have any statement to share on this.
