TEMPE Ariz., Feb. 5, 2008 - Limelight Networks, Inc. (Nasdaq: LLNW) announced that the United States District Court for the District of Massachusetts provided notice of certain rulings today in the Akamai Technologies, Inc. et al. v. Limelight Networks litigation matter. The Court conducted a pretrial conference and ruled on certain pending pretrial motions.

Among its rulings, the Court granted Limelight's motion for summary judgment of noninfringement of U.S. Patent No. 6,553,413, thus removing that patent from the upcoming trial in this matter. The Court ruled on certain other matters, including: that certain fact issues precluded granting Limelight's motion regarding the remaining patent in the case, U.S. Patent No. 6,108,703; denying Akamai's motion on certain equitable defenses; and granting Akamai's summary judgment motion on Limelight's patent misuse defense.

Akamai earlier this week agreed to a judgment that Limelight does not infringe U.S. Patent No. 7,103,645. Akamai also stated that it was no longer alleging willful infringement by Limelight and would not allege, as part of its infringement case, that Limelight had copied any of the allegedly patented features.

The trial in this matter concerning the remaining claims under the '703 patent is scheduled to begin on Monday, February 11, 2008.
