Hannover, April 13, 2016 –Solvay has won two rare earth mixed oxide patent cases against UK-based Molycorp Chemicals & Oxides Ltd in the German Court of Düsseldorf.

The verdict is subject to appeal, but Solvay is entitled to provisionally execute the judgment on past infringing acts from the UK affiliate of U.S. rare earth and rare metals group Molycorp Inc. in Greenwood Village, Colorado.

The regional court handed down two first instance verdicts on March 3rd, 2016, stating that Molycorp Chemicals & Oxides had infringed the German parts of two European patents belonging to Solvay affiliates Rhodia Operations and Rhodia Chimie.

The court found that three products of three grades of cerium containing oxides sold by Molycorp into Germany infringed at least one of the Solvay patents. In addition, the court held that the proceedings filed by Molycorp in the German Federal Patent Court alleging invalidity of the two patents, do not have high chances of success.


Rare earthsmixed oxides are used in applications including the manufacturing of automotive exhaust gas catalysts to abate noxious gases from the engine exhaust. Everstricter air quality standards require ever more complex formulated rare earth mixed oxides.  Solvay’s Optalys™ rare earth mixed oxides product range offers tailor-made solutions for all types of automotive catalysts and contributes to cleaner mobility.
