Laser-sintering systems manufacturer EOS filed a patent lawsuit on March 5 against Phenix Systems 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 announced publicly the commercial manufacture, sale and use of exactly these product lines, even though EOS had apprised Phenix of its patent portfolio several times. Consequently, EOS filed its lawsuit. The complaint against Phenix states that the company directly infringes, induces others to infringe, and contributes to the infringement of both patents in violation of 35 U.S.C. §271. Phenix was notified of the existing EOS patent but continued to engage in acts of infringement. “Filing this patent infringement lawsuit is an essential step in protecting our patent rights in the US,” said Johann Oberhofer, chief financial officer of EOS. “We hope that this litigation will quickly resolve the situation.” For more information, visit: www.eos.info
