Orion sues generic drug companies in the U.S. to enforce patents for entacapone (Orion s proprietary drug Comtan®)



Company states the realisation of generic competition is neither
certain nor imminent


Orion Corporation has filed a patent infringement lawsuit in the
United States to enforce U.S. Patent No. 5,446,194 and U.S. Patent
No. 5,135,950 against generic drug companies Wockhardt USA, Inc. and
Wockhardt Limited, who seek to market generic entacapone (200 mg
tablets) in the United States. Entacapone is the active ingredient in
Comtan®, a product originated by Orion Corporation and marketed in
the United States for the treatment of Parkinson's disease by its
exclusive licensee, Novartis. Orion Corporation and Novartis will
vigorously defend the intellectual property rights covering Comtan.

As previously reported, Orion Corporation was notified in August 2007
that a generic drug company had submitted an Abbreviated New Drug
Application (ANDA) with the U.S. Food and Drug Administration (FDA)
that included a Paragraph IV certification challenging three of Orion
Corporation's patents. By suing to enforce its patents within 45 days
from receipt of the Paragraph IV certification notice, Orion
Corporation is entitled to an automatic stay prohibiting the FDA from
approving the applicant's ANDA for 30 months, or until an earlier
court decision adverse to Orion Corporation's patents in the patent
infringement lawsuit.  As such, the realisation of generic
competition is neither certain nor imminent.
