A patent for a biomass-based polyester, owned by Mitsubishi Chemical Corporation, has been maintained by the European Patent Office (EPO). Several corporations and others had filed notices of opposition to the validity of the patent, but the EPO sided with MCC’s position as to the patent’s validity following oral proceedings on April 15.
It is a substance patent for a biomass-based high-quality polyester and is vastly applicable for business activities such as manufacturing and sales. The corresponding patents have been granted in Japan, the U.S. and China. The EPO’s decision supports the patent’s validity, and MCC will move proactively to defend the patent against future similar objections.
“MCC owns many other patents relating to biomass-based products. It continually expands its own businesses by utilizing those patents and provides licenses to other companies, in order to promote the spread of those products and contribute to global environmental sustainability,” says Johei Takimoto, COO, the Polymer Division.”
