Indivior said on Friday its U.S. subsidiary has filed patent lawsuits against firms seeking approval for generic versions of its opioid addiction treatment Suboxone, which generates 80 percent of Indivior`s revenue.
The lawsuits were filed against Dr. Reddy`s, Allergan Plc`s Actavis Laboratories, Endo International`s Par Pharmaceutical, Alvogen Pharma US, Teva Pharmaceutical Industries and Mylan NV.
The lawsuits allege that these companies have infringed a patent that relates to an oral film containing buprenorphine and naloxone, the London-listed drugmaker said in a statement.
Indivior has already been involved in patent infringement litigations with the same companies over other patents related to the Suboxone film.
