AbbVie flexes litigation muscle with Rinvoq patent lawsuit against Sandoz, other generic players

Looking to protect its lucrative immunology drug Rinvoq, AbbVie is suing a clutch of generic drug makers that are attempting to market copycat versions of the blockbuster.

In a lawsuit filed in Delaware federal court Monday, AbbVie accused Sandoz, Hetero Labs, Aurobindo Pharma, Intas Pharmaceuticals and Sun Pharmaceutical of trying to sidestep dozens of patents protecting Rinvoq through the next decade.
