Power-One Victorious in Patent Infringement Trial

Potter Minton announces that a jury in the Marshall Division of the Eastern District of Texas has ruled in favor of its client, Power-One, Inc., a leading designer and manufacturer of power conversion products.

After six days of testimony, the jury found that defendant, Artesyn Technologies, Inc., had infringed all seven asserted claims of Power-One’s U.S. Patent No. 7,000,125, one of two patents at issue in the trial. Although the jury did not find infringement of the second patent, both patents were found valid. The 125 patent applies to a digital power control system for programming, controlling, and monitoring an array of Point of Load regulators using a data bus.

Power-One filed suit in 2005, shortly after Artesyn, now a part of Emerson Electric Co.’s Network Power business unit, announced the release of its infringing product. As a result, Artesyn never sold the product and only used demonstration prototypes in the marketplace. Despite the absence of sales, Power-One continued the lawsuit to fulfill its goals of proving its patent rights valid, proving its exclusive rights to certain digital power management techniques, and preventing future infringement. The jury verdict successfully accomplished the company’s goals. Since there were no sales of the infringing product, Power-One did not ask the jury to award damages. Instead, the parties stipulated prior to trial to a token damage award of $100. In light of the verdict, Power-One has requested the Court enter a permanent injunction to prevent further infringement.

Potter Minton teamed with Fish & Richardson on the case. Fish & Richardson’s team was led by Alan Smith and Potter Minton’s team was led by Glenn Thames.
