In March 2005, an appeals court directed that there be a retrial, overturning a decision that Microsoft pay $521 million in damages. The appeals court said that the initial ruling had ignored two key arguments put forward by Microsoft. Microsoft had wanted to show the court that ViolaWWW was prior art, since it was created in 1993 at the University of California, a year before the key patent were filed. Microsoft had also suggested that Michael David Doyle, Eolas' founder and a former University of California researcher, had intentionally concealed his knowledge of ViolaWWW when filing the patent claim. Microsoft subsequently settled with Eolas, in August 2007, without a retrial. Eolas continued to file suits against dozens of other technology companies.
