Generic Oxycontin is going off the market.
It looks like this may be the case.
Endo Pharmaceuticals challenged three of Purdue's patents on Oxycontin before they were set to expire. An initial court ruling was that the patents weren't enforceable...opening the door for generics to start entering the market in 2004.
But Purdue appealed soon after. This time it was ruled that Purdue's patents are valid, and that Endo's extended-release oxycodone products infringe the patents.
