Indivior continues legal struggles over Suboxone exclusivity

5 April 2018

The US business of London-listed Indivior (LON: INDV) says it has filed patent infringement lawsuits against Dr Reddy's Laboratories (BSE: 500124), Actavis, Par Pharmaceutical, Alvogen and Teva Pharmaceutical Industries (NYSE: TEVA) relating to their respective proposed generic versions of Suboxone (buprenorphine and naloxone).

Indivior says the firms are violating its '305 patent, which was issued on April 3.

Indivior has been engaged in extensive patent tussles related to the opioid addiction treatment. One adverse ruling in a US District Court last year impacted the firm’s share price considerably, as did a ruling in favor of generic rival Alvogen last month.
