Court Rules Against Mykrolis' Injunction on Pall; Judge Raises Questions About Validity of Mykrolis Patents.

EAST HILLS, N.Y. -- On January 12, 2005 U.S. District Court Judge George O'Toole dissolved the injunction granted to Mykrolis (NYSE: MYK) against Pall (NYSE: PLL) relating to Pall's PhotoKleen(TM) EZD-2 filter assemblies for the semiconductor market. In reviewing the prior art presented to the Court, Judge O'Toole found that there are serious questions about the validity of the Mykrolis patents. Thus the injunction granted on April 30, 2004 is no longer in effect. The Judge also held Pall in contempt of the injunction, which the Court has now dissolved. Pall intends to seek reversal of that ruling as incorrect.

In accordance with the Federal Rules, Pall can now seek to recover payment of costs and damages from Mykrolis that it incurred from having been wrongfully enjoined.

Pall's General Counsel, Gilbert Weiner says, "We are pleased that the Court has now held that the injunction should not have been granted, and that there are serious doubts as to the validity of the Mykrolis patents. Pall is exploring the most expeditious manner of obtaining reversal of the finding of contempt, which may include reactivation of its appeal that has been on hold pending the rulings now issued by the Court."

There were insubstantial revenues from the earlier-generation product subject to the injunction, so there is little, if any, profit to disgorge to Mykrolis. Pall's current model of the slotless PhotoKleen EZD-3 is not a part of this litigation and has not been accused of infringement.
