Patent Lawsuits

In June 2006, Limelight Networks was sued by Akamai Technologies and the Massachusetts Institute of Technology over alleged patent infringement. In April 2009, the District Court for the District of Massachusetts ruled that Limelight Networks did not infringe, overturning the February 2008 finding of a Boston jury. Similarly, in December 2007, Limelight Networks was sued by Level 3 Communications over alleged intellectual property and patent infringement. In January 2009, a jury ruled that Limelight Networks did not infringe. Akamai Technologies appealed part of the decision. On April 20, 2011, the United States Court of Appeals for the Federal Circuit granted the petition by Akamai Technologies for rehearing en banc its appeal in Akamai Technologies, Inc. v. Limelight Networks, Inc. The order vacated the earlier opinion of December 20, 2010. The order includes a request to file new briefs addressing this question: If separate entities each perform separate steps of a method claim, under what circumstances would that claim be directly infringed and to what extent would each of the parties be liable?
