EOS Files Patent Suit Against Phenix Systems
Apr 2012
CHICAGO, April 13, 2012 — 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.”

laser sintering
Commonly known as 3D printing, this process can create three-dimensional parts by fusing small particles of powder. A CO2 laser is used to fuse the particles into a solid material. The laser can selectively fuse the powders by scanning X and Y cross sections of the powder bed. The system builds the object one layer at a time through the use of supplied 3D CAD data.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
