Tekmira alleged that Alnylam had taken advantage of the collaboration to misappropriate Tekmira's secret RNAi delivery and manufacturing technology, including by applying for patents on technology developed by Tekmira and by passing off Tekmira's technology as its own. Two days before jury selection, the case settled with Alnylam agreeing to pay Tekmira $75 million in cash and near-term milestone payments, and agreeing to transfer patents and patent applications to Tekmira. Alnylam also agreed to dismiss counter-suits for patent infringement that it had filed in Massachusetts and Canada.
