MEMC Electronic Materials Inc. disclosed that a lawsuit has been filed against Soitec, a maker of silicon-on-insulator wafers, for violation of MEMC's European patents on defect-free silicon, referred to as Perfect Silicon.

The lawsuit, which was filed with the First Instance Court in Lyon, France, follows a seizure which MEMC conducted in accordance with French law at Soitec's facility in Bernin, France on Dec. 15, 2005. The lawsuit pertains to the same family of patents for which MEMC recently received favourable rulings in the U.S. Court of Appeals and the European Patent Office.

MEMC had previously requested and received the seizure order from the First Instance Court in Lyon. During the seizure, evidence was collected which MEMC believes shows clear violation of its patents by Soitec.

"We believe that Soitec infringes our patents that protect the use, manufacture and sale of Perfect Silicon wafers. We have filed suit following the seizure of evidence, and intend to vigorously pursue this matter using all available remedies, including past damages, royalties, lost profits and injunctions," said MEMC chief executive Nabeel Gareeb.
