On Aug. 6, 2012, a jury in the case of Brocade v. A10 Networks found for Brocade on four claims of patent infringement involving technologies for Global Server Load Balancing and High Availability and found that the A10 AX Series line of load balancers infringe on these specific patents. The jury found A10 liable for copying Brocade code used in Brocade's ServerIron products; misappropriation of four trade secrets involving techniques used in ServerIron; and unfair competition based on interference with the contract of an engineer while he was employed at Foundry Networks, which Brocade acquired in late 2008.
"We appreciate the Court's careful attention to the evidence and its willingness to enforce important intellectual property rights," said Tyler Wall, vice president and general counsel at Brocade, in a statement. "The jury found A10 guilty of broad-based intellectual property infringement and unfair competition. We are very pleased that this permanent injunction will stop A10 from unlawfully using Brocade's patents."
A10 said the ruling will have no material negative impact on its business or financial strength. It also says the U.S. Patent & Trademark Office has rejected the Brocade patents in question, and that the Federal Circuit will take that into account upon A10's appeal.
