EOS files patent infringement lawsuit against MCP in the US

EOS GmbH Electro Optical Systems, a manufacturer of laser-sintering systems, today announced that it has filed a patent infringement lawsuit in the US District Court, South Carolina, against MCP Tooling Technologies Ltd. and MCP-HEK Tooling GmbH. The lawsuit alleges infringement of US Patent No. 5,753,171 through the manufacture, sale, and use of the Realizer product line from MCP in the US.

In February 2008, EOS and Trumpf had announced a patent license agreement with MCP. Under the agreement, MCP received a non-exclusive license for certain EOS patents, as well as some patent rights from Trumpf regarding the laser-sintering process. These patents are relevant to MCP's product line "Realizer." However, the license does not extend to the USA and Canada. 3D Systems and MCP then announced in the same month that the MCP Realizer would be distributed in the US. As a consequence, EOS filed the patent infringement lawsuit against MCP on May 8, 2008.

Johann Oberhofer, COO and managing director of EOS, comments: "Filing this patent infringement lawsuit is an essential step for protecting our patent rights in the US. We hope that this litigation will quickly resolve the situation."

EOS has had patents granted for a considerable number of its own inventions in the field of laser-sintering. Today, the EOS patent portfolio includes more than 50 patent families worldwide. The company also owns exclusive worldwide rights to all patents owned by 3D Systems Corp. applicable to the field of laser-sintering which were filed prior to August 20th, 2002.
