Are There Other Patents Protecting Stelara?
Yes, in addition to the main patent, Stelara is protected by other patents [3]. These may cover aspects such as specific formulations, manufacturing processes, or methods of use [3]. These secondary patents can sometimes extend the period of market exclusivity beyond the expiration of the primary patent. DrugPatentWatch.com tracks these patent landscapes [1].
When Does Stelara's Exclusivity End in the US?
