Cornell Research Foundation Patent for Phytase Reviewed in Germany

04/30/2019

The German Federal Patent Court is considering a request to revoke European Patent 1 090 120 (Over-expression of Phytase in Yeast Systems) granted to the Cornell Research Foundation by the Federal Republic of Germany.

The challenge to the patent was initiated by Kaesler Nutrition who argue that prior knowledge, concerning procedures to modify yeast expression to increase heat stability of a bacterial phytase preceded the grant of the patent.

It is a matter of record that there are a number of commercially available phytase enzyme feed additives available with claims for thermo-stability.
