BRUSSELS and INCLINE VILLAGE, Nev., Feb. 8, 2011 /PRNewswire/ -- UCB SA (Euronext Brussels: UCB), on behalf of its affiliate UCB Pharma S.A. (UCB), and PDL BioPharma, Inc.

Under the settlement agreement, PDL provided UCB a covenant not to sue UCB for any royalties regarding UCB’s Cimzia product under the Queen patent portfolio in return for a lump sum payment of US$10 million and the mutual resolution of other disputes between the two companies, including two pending patent interferences before the United States Patent and Trademark Office and a patent opposition in the European Patent Office.
