Federal District Court Issues Vicor Patent Rulings

January 15, 2003 by Jeff Shepard

Vicor Corp. (Andover, MA) announced that the Federal District Court, Boston, MA, issued several decisions interpreting Vicor's Reset US Patent 36,098. The court issued a decision in each of Vicor's patent-infringement lawsuits against Artesyn Technologies Inc., Lambda Electronics, Lucent Technologies Inc., Tyco Electronics Corp. and Power-One Inc. Vicor filed the lawsuits seeking damages to compensate Vicor for the unauthorized use of its Reset Patent technology.

The court denied Artesyn's claim that claim one of the Reset Patent is invalid for indefiniteness and ruled that Vicor is not judicially estopped from asserting its interpretation of claim one. The court also adopted Vicor's interpretation of several terms within claim one. However, the court adopted interpretations of certain patent claim terms that are contrary to Vicor's position. Vicor believes that, taken together, these rulings strengthen Vicor's position regarding the validity of the Reset Patent, but also incorrectly limit the scope of the claims of the Reset Patent, which could have the effect of reducing the cumulative amount of infringing power supplies and the corresponding amount of potential damages.

Vicor plans to pursue recovery of damages and to protect its position as to the full scope of the patent claims.
