ROVALMA successfully protects its patent rights against attack by Böhler-Edelstahl GmbH & Co.KG



With its decision from December 2017, the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO) upholds ROVALMA’s patent of High-Thermal-Conductivity Hot work steels with thermal conductivities > 42 W/mK, thereby rejecting the petition submitted by Böhler-Edelstahl GmbH & Co. KG in 2014 to cancel the ROVALMA patent.


Based on this decision, we advise tool steels buyers and users when offered this kind of products by other providers to check, if the products are not in conflict with ROVALMA patents on High Thermal Conductivity hot works steels and hence possibly present a legal infringement of ROVALMA’s patent rights.
