An Ohio manufacturer of electronic cigarettes has accused the R.J. Reynolds Vapor Company of patent infringement.
The Winston-Salem Journal reports that Fuma sued the North Carolina-based subsidiary of Reynolds American in federal court on Wednesday.
The lawsuit says Fuma and Reynolds entered into a confidentiality agreement in 2010 that allowed Reynolds to review Fuma's e-cigarette designs as part of a potential investment or joint venture. Fuma says Reynolds then copied its design for use in Vuse products.
Vuse debuted in 2012 and has become the second highest-selling e-cigarette on the U.S. market. Fuma's patent was awarded in 2017.
Fuma is requesting a permanent injunction against Vuse, as well as damages of an unspecified amount.
The newspaper couldn't immediately reach Reynolds officials for comment.
