Sony, university settle Playstation chip spat

Campus newspaper The Daily Cardinal said that the fight was over a diffusion barrier which UW-Madison claims to have invented.

The barrier prevents copper and silicon from interacting with each other. The paper quoted a WU-Madison representative as saying that details of the settlement are confidential.

The Wisconsin Alumni Research Foundation (WARF) owned a patent on the technology but it appears Sony was unaware of this. The licensing deal could run into a significant amount of money, which won't go to the inventors but to WARF.
