British pharma company Indivior has suffered a setback as U.S. Federal Court of Appeal rejected their request for another hearing on whether its patents were infringed by a low-cost alternative developed by Dr Reddy.

Indivior states it intends to continue appeals against the Delaware patent ruling and also in the New Jersey court against Dr Reddy and Alvogen.
