Item 8.01.

Other Events.

On March 16, 2007, after approval of Alexion Pharmaceuticals, Inc.’s (“Alexion”) Soliris™ (eculizumab) humanized antibody product by the U.S. Food and Drug Administration, in order to protect PDL BioPharma, Inc.’s (the “Company”) intellectual property rights, the Company filed a lawsuit against Alexion seeking monetary damages for infringement of certain of the Company’s patents. Because the Company does not seek to deprive patients with paroxysmal nocturnal hemoglobinuria and physicians from access to Alexion’s Soliris™ (eculizumab) humanized antibody product, the Company is not seeking an injunction against Alexion. The Company has not yet served its complaint on Alexion.

The Company has contacted Alexion about a license to Alexion under certain of the Company’s antibody humanization patents, commonly referred to as the Queen patents, and is seeking to meet with Alexion to discuss negotiation of license terms.
