MEDICIS RECEIVES NOTICE OF ALLOWANCE FOR SOLODYN^® PATENT

SCOTTSDALE, Ariz.—October 13, 2009—Medicis (NYSE:MRX) today announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for Medicis’ United States patent application directed to the use of SOLODYN^® (minocycline HCl, USP) Extended Release Tablets in all five currently available dosage forms.

The patent application is U.S. Application No. 11/166,817, entitled “Method For The Treatment Of Acne.” The newly allowed claims include subject matter covering methods of using a controlled-release oral dosage form of minocycline to treat acne.

“We are pleased to announce receipt of this Notice of Allowance by the USPTO,” said Jonah Shacknai, Chairman and Chief Executive Officer of Medicis. “This represents yet another important element of maintaining the SOLODYN franchise. When issued, these allowed patent claims will further enhance the intellectual property protection of the SOLODYN brand.”

A Notice of Allowance generally completes the substantive examination of a patent application. The normal process which results in final issuance of a United States patent involves several administrative steps that are typically completed in due course following issuance of such a notice.

SOLODYN has three issued patents. U.S. Patent No. 5,908,838 relates to the use of the SOLODYN unique dissolution rate, and expires in 2018. U.S. Patent No. 7,541,347 relates to the use of the 90mg controlled-release oral dosage form of minocycline to treat acne, and expires in 2027. U.S. Patent No. 7,544,373 relates to the composition of SOLODYN in 90mg tablet form, and expires in 2027. As of today, the Company has a number of U.S. patent applications associated with the SOLODYN program on file at the USPTO.
