UWisc has always been very aggressive with its patents. I recall sometime during 2002 or thereabouts, while working for a reasonably big semiconductor company with DSP&#x2F;ARM processors, one of the guys in our team with an interest in computer architecture, used the company network to download and play with a simulator or something (might have been simplescalar). A few weeks later the head of our group gets contacted by the company lawyers saying that UWisc was asking for licensing costs for using their tools (they provided the ip address that was used to download the tools). I&#x27;m not sure how it was resolved finally, but I don&#x27;t think the company paid.
