Cambridge, MA |

Akamai Technologies, Inc. (NASDAQ: AKAM) today announced that it intends to appeal a decision by the judge presiding over its patent infringement suit against Limelight Networks, Inc. in the U.S. District Court of Massachusetts. The decision, released today, granted a Limelight motion challenging a prior jury finding of infringement, based on new case law.

In February 2008 a jury returned a verdict that Limelight was infringing a patent asserted by Akamai and awarded Akamai over $45 million in damages. The verdict, which came at the end of a three-week trial in Boston, stemmed from a lawsuit that Akamai had filed in 2006. The jury found that Limelight infringed all four of the claims that Akamai had asserted in its Internet content delivery patent, U.S. patent 6,108,703, issued in the name of Akamai founders Tom Leighton and the late Danny Lewin.
