EOS Files Patent Suit

Laser-sintering systems manufacturer EOS of Krailling, Germany, filed a patent lawsuit March 5 against Phenix Systems of Riom, France, for infringing two US patents for its dental product lines, the company announced. The lawsuit alleges infringement of US Patent Nos. 5,753,274 and 6,042,774 through the manufacture, sale and use of the PXL, PXM, PXS and PXS Dental product lines from Phenix in the US. During the second half of 2011, Phenix publicly announced the commercial manufacture, sale and use of exactly these product lines, even though EOS had apprised Phenix of its patent portfolio several times, EOS alleges.
