EOS sues MCP for U.S. patent infringement

May 19, 2008
German-based laser-sintering manufacturer EOS GmbH Electro Optical Systems had filed a patent infringement lawsuit against MCP Tooling Technologies.

EOS GmbH Electro Optical Systems (Krailling, Germany), manufacturer of laser-sintering systems, has announced that it has filed a patent infringement lawsuit in the South Carolina U.S. District Court against MCP Tooling Technologies Ltd. (Stone, England) and MCP-HEK Tooling GmbH (Lübeck, Germany). The lawsuit alleges infringement of U.S. 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 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," a line of selective laser melting (SLM) equipment that melts and shapes metal materials like steel and cobalt-chrome. However, the license does not extend to the U.S. and Canada. In the same month, 3D Systems and MCP announced that the MCP Realizer would be distributed in the U.S. As a consequence, EOS filed the patent infringement lawsuit against MCP on May 8th, 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 U.S. 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 Corporation applicable to the field of laser-sintering which were filed prior to August 20th, 2002.
