WARF is the arm of the University of Wisconsin-Madison science
and research team that deals with getting and enforcing
patents.
According to reports, it is enforcing a patent that covers the
making of a chip, rather than the chip itself. WARF says this
patent is being infringed by the making of the PS2's so-called
Emotion Engine integrated processor.
A WARF spokesman told CNet News that other companies had
licensed its patent technology. He said of Sony and Toshiba's
refusal, "We hope the lawsuit will encourage them to bargain in
good faith".
