Item 8.01. Other Events.

On June 15, 2011, in our litigation against Endicia, Inc. and PSI Systems, Inc. originally filed by us on November 22, 2006, the United States Court of Appeals for the Federal Circuit affirmed the summary judgment ruling of the district court that the fifteen claims we selected from eight patents are invalid. We were required to select fifteen claims from amongst the over six hundred claims available in the eleven patents we initially asserted.

A second lawsuit, which was filed by PSI Systems, Inc. August 8, 2008, and in which we have asserted four additional patents against PSI, was not the subject of this ruling and remains pending.

For further information about Stamps.com litigation, please refer to our quarterly report on Form 10-Q for the quarter ended March 31, 2011.
