The Industry-University Cooperation Foundation Hanyang University (IUCF-HYU) has filed two international patents relating to fibers which contain graphene. Both point to earlier patents filed in Korea. Patent number WO2012124937 describes a graphene-polymer conjugate fiber, while patent number WO2012124935 describes hybrid fibers consisting of polymer and graphene or carbon nanotubes. While there is not much information in English in these patent descriptions, we can’t help but be reminded of the US patent application by Vorbeck and Kordsa which we reviewed yesterday. It seems that these Korean patents overlap at least to some extent with the Vorbeck patent application, which intends to protect the use of such fibers in vehicle tires. However, Vorbeck does already own patents on certain fiber mixtures of graphene, graphite and polymer.
