sentences:  Haptics developer Immersion Corporation, which had successfully sued Sony for patent infringement, expressed skepticism of Sony's rationale, with company president Victor Viegas stating in an interview, "I don't believe it's a very difficult problem to solve, and Immersion has experts that would be happy to solve that problem for them", under the condition that Sony withdraw its appeal of the patent infringement ruling.Immersion later emphasized compatibility with motion-sensing when introducing its next-generation vibration feedback technology, TouchSense.Subsequent statements from Sony were dismissive of the arguments from Immersion, with SCEA Senior VP of Marketing Peter Dille stating, ""It seems like the folks at Immersion are looking to sort of negotiate through the press and try to make their case to us … we've talked about how there's a potential for that rumble to interfere with the Sixaxis controller.""
