Supply Vendor Responds to Suit Concerning Digital Power IP

Artesyn Technologies Inc., Boca Raton, Fla., issued the following statement with regard to the suit filed by Power-One Inc. on Sept. 30, 2005, in the U.S. Court for the Eastern District of Texas, Marshall Division (as well as the press release that Power-One issued describing the suit):

Artesyn is very diligent about intellectual property ownership during its product development process. It believes that it has defenses to the suit filed by Power-One, intends to assert them vigorously and expects to prevail. Artesyn believes in competing aggressively and fairly in the marketplace based upon the merits of its products. This lawsuit and the accompanying press release by Power-One appear, in Artesyn’s opinion, to be a baseless attempt to slow the adoption of the PMBus protocol through the courts instead of through technical merit. While Power-One has chosen to invest in a proprietary system architecture, Artesyn believes the future of digital power management is better served with an open architecture such as the PMBus protocol, which has already gained significant support from numerous power supply and semiconductor companies, as well as system OEMs.

Artesyn Technologies Inc. designs, manufactures and sells power conversion and embedded board solutions. The Power Management Bus (PMBus) protocol initiative is a collaborative venture by the industry to establish an open communications standard for the digital control of power systems. PMBus is supported by the System Management Interface Forum (SMIF).
