Business Wire

BETHESDA, Md. -- February 8, 2013

Sucampo Pharmaceuticals, Inc. (NASDAQ: SCMP) today announced that it, its
affiliate Sucampo AG, R-Tech Ueno, Ltd., Takeda Pharmaceutical Company Limited
(Takeda), and certain affiliates of Takeda have filed a patent infringement
lawsuit in the United States District Court for the District of Delaware
against Anchen Pharmaceuticals, Inc., Par Pharmaceuticals, Inc. and Par
Pharmaceutical Companies, Inc. (collectively, Anchen) related to an
Abbreviated New Drug Application (ANDA) that Anchen filed with the U.S. Food
and Drug Administration (FDA) to market a generic version of AMITIZA^®
(lubiprostone) oral capsules, 8 mcg and 24 mcg. The lawsuit claims
infringement of six patents that are listed in the FDA’s Orange Book and that
are scheduled to expire between 2020 and 2027.

Sucampo commenced the lawsuit within 45 days from the receipt of a Notice
letter sent by Anchen, dated December 26, 2012, regarding its filing of its
ANDA. Under the Hatch-Waxman Act, as a result of the patent infringement
lawsuit, final FDA approval of Anchen’s ANDA will be stayed up to 30 months
from the January 2, 2013 date of receipt of the Notice letter.

“Sucampo’s patent estate for AMITIZA^® is strong, and the company intends to
vigorously defend our intellectual property. We believe that the AMITIZA^®
patents, granted by the US Patent & Trademark Office, are valid, enforceable,
and infringed by Anchen’s proposed lubiprostone products,” said Thomas J.
Knapp, Executive Vice President, Chief Legal Officer, and Corporate Secretary
of Sucampo.
