Sigma-Aldrich Corp. and Oxford BioMedica have filed a lawsuit against Open Biosystems Inc. for infringement of patents that cover key lentiviral-based systems for delivery of foreign DNA to a broad array of mammalian cells. A lentivirus is a retrovirus, or one that has an RNA (ribonucleic acid) genome. The complaint, which was filed in U.S. District Court for the Eastern District of Missouri, alleges that Open Biosystems is infringing on two U.S. patents. Rights to the patents, both titled Lentiviral LTR Deleted Vector, were exclusively licensed for research use to Sigma-Aldrich by Oxford BioMedica in October 2005. The suit states that, among other products, Open Biosystems' Lentiviral shRNAmir Library is marketed and sold to researchers and research institutions for incorporation into viral particles that infringe one or more claims of the patents. Sigma-Aldrich said in a release that the lawsuit filed against Open Biosystems is a result of the company's "desire to actively protect its intellectual property in this field."
