Fenner Investments has a patent on a port which interfaces a typical five volt joystick device with a computer.
Vole, Nintendo and Sony are "now engaging, and will in the future continue to engage, in unauthorized conduct and activities that violate" the patent, Fenner said.
It wants huge wodges of cash in compensation, punitive damages, attorney fees, and court costs.
However, although Fenner claims to hold the patent number 6,297,751 the design was developed by Lucent in 1998. According to CIO Today, Fenner might have acquired legal rights to the patent, but it is not saying how.
Fenner might be hoping that it will do better in this case than the last. It lost a lawsuit against Alcatel, Nokia, and Cisco in a patent case over wireless technology recently.
