In February 2012 a Texas jury found that two of Eolas' patents were invalid after testimony from several defendants including Tim Berners-Lee and Pei-Yuan Wei, credited as creator of the Viola browser. The testimony professed that the Viola browser included Eolas' claimed inventions before the filing date (September 7, 1993). There is "substantial evidence that Viola was publicly known and used" before the plaintiffs' alleged conception date, it added. The ruling effectively ended a pending lawsuit against 22 companies including Yahoo, Google, and many online retailers.
