If you’ve been keeping up with your technology news over the years, the name Eolas may very well ring some alarm klaxons. The company famously took Microsoft to court for infringement, alleging that the software giant’s Internet Explorer Web browser violated Eolas’s patent on a Web browser containing plug-ins. That trial began in 1999; in 2005, the U.S. Supreme Court declined to hear an appeal from Redmond and two years later, the two companies finally settled. Now, Eolas is suing a host of other companies, including Apple, over the same patent.
