Generic Suboxone film hits a legal snag

Although a court ruling in September 2017 appeared to pave the way for sales of a generic form of Suboxone film, the manufacturer of the opioid treatment drug has filed a new patent lawsuit aimed at preventing the generic product from hitting the market.

The September court decision ruled that the various generic manufacturers did not violate any patents owned by Indivior, the company that manufactures Suboxone and derives about 80 percent of its sales from the drug.

However, Indivior obtained a new patent in January 2018, and now claims that the generic versions violate the new patent. The new patent covers polymers and other agents designed to create a uniform distribution of the drug and prevent the filmstrips from adhering to each other or to the user’s mouth.
