Morning Movers: Power-One Announces Favorable Ruling in Patent Litigation

Mar 23, 2007 (M2 PRESSWIRE via COMTEX) -- Market Gainer is quickly emerging as the one stop shop for international small-cap investors looking to stay a step ahead of the markets. Today's activity on the markets has brought these companies to the attention of our research team. On the NASDAQ exchange Power-One, Inc. (NASDAQ:PWER - News), is responding to the attention of investors. Our goal is to create a community of international investors who consistently and effectively capitalize on the enormous gains the small-cap Canadian and American exchanges offer.

Power-One, Inc. (NASDAQ:PWER - News) today announced that the U.S. District Court for the Eastern District of Texas, Marshall Division, has completed the Markman hearing and yesterday issued its claim construction ruling on March 22. The ruling decides a number of important issues in favor of Power-One and strengthens Power-One's patent infringement claims as it proceeds to a jury trial.

The Court's ruling rejects a defense raised by Artesyn Technologies (a wholly owned subsidiary of Emerson Electric Co.) that Power-One's patents are invalid as being indefinite. The Court denied Artesyn's defense by finding that the claim term point-of-load ("POL") regulator, which is an integral part of all the patent claims, has a legally definite meaning. The Court ruled that POLs are a "known device in the art," and that "This evidence plainly suggests that POLs were well known devices whose locations and functions relative to other components was understood by those of ordinary skill in the art." For the hotly contested claim term POL, the Court wholly adopted Power-One's claim construction, finding that Power-One was legally correct. The Court also established the meaning of numerous other contested terms in the patent claims. A significant majority were construed in favor of the definitions proposed by Power-One.

Bill Yeates, CEO, commented, "The Court's ruling is a big positive for our litigation and validates our belief in the broad meaning and scope of our patent claims. We have asserted in the litigation that Artesyn infringes 82 claims in 4 patents. This ruling provides very substantial support for our assertion that Artesyn is infringing Power-One's patents with its PMBus compliant DPL20C point of load converter. We fully expect the jury to find that Artesyn is infringing our patents when the trial is held in August".

Mr. Yeates continued, "As this lawsuit indicates and as we have been communicating to our investors for some time now, our Z-One technology is the most innovative, advanced, and feature-rich technology for this power marketplace. Since we started our work in this ground-breaking technology, Power-One has been leading digital power IP development to combine power management and power conversion in a system. Due to major developments in the past few years, we now have many products which effectively address the needs of customers within this market."

The four Power-One patents in the lawsuit generally concern digital power management and control of POLs on the circuit board. Power-One has incorporated this technology into its Z-One products and system architecture, which allows for the central control of distributed point of load power regulators. In addition to the issued patents in this lawsuit, Power-One has a growing family of system and element-specific patents and patent applications covering its Z-One products and architecture.

Following this announcement Power-One, Inc. (NASDAQ:PWER - News), was trading up over 12% in early trading. The Market Gainer Research Team will continue to gauge the short and long term affects that this announcement will have on the company.
