“We are disappointed by the Court’s decision, as we continue to believe that our Ampyra patents reflected true invention and were valid. We are reviewing the decision and will consider future options, including the possibility of a further appeal,” said Ron Cohen, M.D., Acorda's President and CEO. “Following the Court’s original decision in 2017, we prepared a contingency plan that we could face generic competition, implementing a comprehensive corporate restructuring and bolstering our balance sheet. As a result, we are well-capitalized and fully focused on the potential launch of Inbrija for Parkinson’s disease.”
