Novo Nordisk just settled with Viatris, a company which was trying to have the Ozempic patent cancelled.[1] That would have killed their monopoly. "Terms of the settlement are confidential".

They just did the same thing with Mylan.[2]

And may have done something similar with Rio Pharmaceuticals.[3]

The Federal Trade Commission is also fighting that.[4]
