Federal Circuit Court Of Appeals Affirms Power-One’s Capstone Patent For Digital Power Technology

Power-One, Inc. (Nasdaq:PWER), a leader in digital power technology (DPT) and a provider of renewable energy and energy-efficient power conversion and power management solutions, announced today that the Federal Circuit Court of Appeals has ruled in its favor in the appeal by Artesyn of the United States District Court’s decision in Power-One, Inc. v. Artesyn Technologies, Inc. (Eastern District of Texas, Civil Action No. 2-05-CV-463 (LED)).

“This decision affirms the validity of the capstone patent in our DPT portfolio and confirms the strength of our patents. The ruling underscores the importance of our strategy to grow the DPT market through licensing and manufacturing and to offer the end-customer a range of best-in-class, energy efficient products that reduce energy consumption,” said Richard Thompson, President and Chief Executive Officer of Power-One.

Affirming the lower court’s decision in favor of Power-One, the Court of Appeals determined that the term “POL regulator” is a term whose meaning is understood by one skilled in the art of distributed power systems. The court also found that the evidence presented at trial was sufficient to support the jury’s conclusion that Artesyn copied Power-One’s patented invention and to defeat Artesyn’s obviousness claim.

The confirmation of the ruling highlights the strength of Power-One’s portfolio of patents and opens the market for DPT products created by Power-One and other validly licensed users of its technology. The integration of digital power management enables OEM’s and data centers, including websites, to design products that run more efficiently. As the number of POL’s on boards continues to increase, and data centers utilize more power from the grid, the need for digital power management solutions intensifies. Digital control technology, where analog control functionality is replaced by digital circuitry, reduces cost while increasing performance through size, performance and configurability advantages. The increased adoption of DPT is leading the digital power market to become one of the fastest growing markets in power management.
