H. Lundbeck A/S is pursuing legal proceedings in India against Alembic Pharmaceuticals Limited and Hetero Drugs Ltd. for allegedly infringing its patent pertaining to the antidepressant Brintellix (vortioxetine), a product that is a key revenue contributor globally for the Danish firm and one that has also seen generic opponents lining up in the US.
