Plainsboro, N.J.-based Integra wants a jury trial, an injunction barring the manufacture and sale of the Adherus products and triple damages for willful infringement, plus
The lawsuit asks the court to enjoin HyperBranch from continuing to make, sell, and offer to sell the Adherus products and to grant treble damages for willful infringement, according to the documents.
