MBI and Mallinckrodt Receive Notice of Lawsuit
San Diego, California and St. Louis, Missouri, May 5, 1999 - Molecular
Biosystems, Inc. (NYSE: MB) and Mallinckrodt Inc. (NYSE: MKG) said today that
the two companies will aggressively defend their rights to manufacture and sell
OPTISON(r), the only advanced generation cardiac ultrasound imaging agent
commercially available in the United States and Europe.
The announcement was made after DuPont Pharmaceuticals Company ("DuPont") and
ImaRx Pharmaceutical Corp. ("ImaRx") filed a lawsuit in the United States
District Court for the District of Delaware against MBI and its marketing
partner Mallinckrodt. The lawsuit alleges that the manufacture and sale of
OPTISON infringes U.S. Patent No. 5,547,656 owned by ImaRx and exclusively
licensed to DuPont.
"MBI firmly believes that the patent is invalid and the manufacture and sale of
OPTISON does not infringe this patent," stated MBI's President and CEO Bobba
Venkatadri. He further stated, "We will take all actions necessary to preserve
MBI's and Mallinckrodt's right to manufacture and sell OPTISON." Bradley J.
Fercho, president of Mallinckrodt's Imaging Group, said that the two companies
expect to vigorously defend against the legal actions being pursued by their
competitors.
Developed by MBI and marketed in the United States and Europe by Mallinckrodt,
OPTISON is used in more than 1,600 hospitals and cardiology group practices in
the United States, Germany, Spain and the United Kingdom. MBI holds more than
60 valid patents worldwide protecting its proprietary microsphere technology,
which has enabled the development of OPTISON.
MBI, based in San Diego, California, is a world leader in developing contrast
agents for diagnostic imaging. Its innovative product, OPTISON, enables
improved diagnosis of heart disease through clearer ultrasound images.
Based in St. Louis, Missouri, Mallinckrodt has three healthcare product groups -
Imaging, Pharmaceuticals and Respiratory. It operates in more than 100
countries and had fiscal 1998 sales of $2.4 billion.
This news release contains forward-looking statements that involve risks and
uncertainties. Among the factors that could result in a materially different
outcome are: the failure of OPTISON to gain market acceptance either in the
U.S. or other markets; an adverse result in MBI's and Mallinckrodt's pending
patent lawsuits, including the lawsuit announced by DuPont and ImaRx, or an
adverse ruling by the PTO in the pending patent reexaminations; and other risk
factors reported from time to time in MBI's and Mallinckrodt's filings with the
Securities and Exchange Commission.
