Akamai Technologies prevailed in its patent infringement case against rival Limelight Networks over technology for storage and delivery of video content over the network.
The US Federal Court of Appeals found Limelight infringed an Akamai patent.
The appeal sprung from a 2008 case when a jury ruled that Limelight was infringing the patent and awarded Akamai $45m in damages in a high profile case between the Content Delivery Network rivals.
Akamai deputy general counsel Aaron Ahola said: "We are extremely pleased with The Federal Circuit’s decision.
"Akamai is at the forefront of innovation on the Internet and today’s ruling recognizes the strength of our intellectual property. We believe strongly that a company’s intellectual property is a vital asset which must be defended to protect shareholder value. "
Limelight issued a statement which said: "While Limelight studies all options and determines its next steps, the company believes its balance sheet is strong enough to continue to invest in the business and respond to any potential outcome in its continuing court battle with Akamai."
"We are disappointed this outcome isn’t aligned with the recent rulings in our favor, which were supported by many global technology and industry leading companies, and are determined to continue the process," stated Bob Lento, Limelight’s chief executive officer. "Our business is strong and gaining strength. Our network traffic is growing at a record pace. We are investing in our business, improving margins and are confident of our future. We will not allow this to distract us from serving our global customers."
