Allergan and Alcon Reach Agreement on Brimonidine 0.15% Patent Litigation

IRVINE, Calif.--(HSMN NewsFeed)--March 9, 2006--Allergan, Inc. (NYSE:AGN ) announced today that Allergan and Alcon, Inc. (NYSE:ACL ) have settled Allergan's patent infringement lawsuit in the United States District Court for the District of Delaware contending that Alcon's proposed brimonidine 0.15% product infringes two brimonidine-related patents owned by Allergan. Pursuant to the settlement:

1. Alcon has agreed to a license beginning on September 30, 2009, in the United States under both patents at issue in the Delaware lawsuit;

2. Alcon will not sell, offer for sale or distribute its brimonidine 0.15% product until September 30, 2009, or earlier if certain market conditions occur, the primary condition being a trigger based generally on the extent to which prescriptions of ALPHAGAN(R) P 0.15% have been converted to other brimonidine-containing products (including ALPHAGAN(R) P 0.1% and COMBIGAN(TM)) marketed by Allergan.

3. Upon market entry of Alcon's 0.15% brimonidine product, Alcon will pay Allergan royalties on the sale of its product in the United States.

"We are pleased with this settlement and the delayed-entry license taken by Alcon, which respects our intellectual property portfolio," said David E.I. Pyott, Allergan's Chairman of the Board and Chief Executive Officer. "This delayed-entry license, which we are confident will not commence until September 30, 2009, is in line with Allergan's long-term strategy for our overall brimonidine franchise."

Additionally, Allergan has dismissed a separate patent infringement lawsuit filed by Allergan against Alcon in the United States District Court for the District of California related to self-preserved ophthalmic antibiotics.

Allergan's ALPHAGANŽ franchise has been a leading therapy for reducing intraocular pressure (IOP) in patients safely and effectively for more than five years. ALPHAGANŽ, ALPHAGANŽ P 0.1% and ALPHAGANŽ P 0.15% are indicated for lowering IOP in patients with open-angle Glaucoma or ocular hypertension.
