ROCK HILL, S.C., March 24, 2011 (GLOBE NEWSWIRE) -- 3D Systems Corporation (Nasdaq:TDSC) announced today that the United States District Court for the Eastern District of Michigan, Southern Division, has entered a judgment of patent infringement in its favor against Envisiontec, Inc., Envisiontec GmbH and SIBCO, Inc. (collectively, "Envisiontec") in a case brought by the company.

The Court ruled that Envisiontec's Perfactory® systems infringe a claim of the company's U.S. Patent Number 5,630,981 and that Envisiontec's Vanquish systems (currently sold under the PerfactoryXede® and PerfactoryXtreme® names) infringe a claim of each of the company's U.S. Patent Numbers 5,630,981 and 5,651,934. Both of these patents relate to the company's stereolithography technology.

"We are very pleased with this decision," said Abe Reichental, 3D Systems' President and Chief Executive Officer. "The District Court's ruling confirms our long-held belief that Envisiontec has been violating 3D Systems' intellectual property rights."

3D Systems has commercialized the patents found to be infringed by Envisiontec, as well as other patented inventions, in its ViperTM and iProSLA® production printers, among others.
