Ajinomoto files new patent infringement suit over feed-use lysine

Ajinomoto and Ajinomoto Eurolysine have filed a new patent infringement suit against Global Bio-chem Technology Group over feed-use lysine.

Ajinomoto Co. Inc. and Ajinomoto Eurolysine S.A.S. have filed a new patent infringement suit against Global Bio-chem Technology Group Company Ltd. with its three subsidiaries (collectively GBT), before the District Court in The Hague, the Netherlands on July 25.

So far, various courts in Europe have issued injunctions against GBT. However, the Ajinomoto companies claim that GBT infringes another patent owned by Ajinomoto.

Ajinomoto and Ajinomoto Eurolysine request the court to order GBT to stop selling infringing lysine immediately, to recall already sold lysine and also to pay the damages.

The companies have recently requested the authorities to seize several samples of GBT lysine sold in Europe. After careful analysis, companies are of the opinion that lysine presently sold by GBT infringes Ajinomoto Co. Inc.'s patents. Companies are therefore forced to initiate new patent enforcement proceedings. In the new proceedings, the Ajinomoto companies assert a new European Patent (EP 1 664 318), which is valid until 2025. This patent is different from the three patents for which the companies filed complaints against GBT in the Netherlands and other European countries. Equivalent patents for EP 1 664 318 exist for many countries outside of Europe.

The Ajinomoto Group has been making intensive investments in research and development for advanced production technologies for amino acids and has committed itself to contribute to the feed and animal nutrition industry as world-leading amino acid producing company. The Ajinomoto Group believes that infringement of its intellectual property obstructs its R&D efforts and, therefore, the Ajinomoto Group will continue to pursue necessary measures to protect its legitimate rights.
