Laser sintering companies resolve dispute

April 24--EOS and TRUMPF have reached a patent license agreement with Concept Laser, which brings to an end all outstanding laser sintering rapid manufacturing patent infringement and opposition actions between the companies.

The agreement provides Concept Laser, part of the Germany-based Hoffmann Innovation Group, with non-exclusive use of some of EOS and TRUMPF European and U.S. patents, allowing it to market its LaserCusing sintering systems in all global markets outside the U.S.

In a separate move, EOS acquired a preliminary injunction against CRP, which markets the Windform XT carbon-filled PA12 laser sintering powder, claiming that the Italian company is making misleading statements to users about its patent position.

EOS claims to have published its own patent applications covering carbon fiber filled PA12 laser sintering powders that predate all CRP's patent filings.
