Successful opposition defences of Cristal’s titanium dioxide patents
Cristal is a global manufacturer of titanium dioxide and specialty titanium products. Carpmaels was entrusted with defending oppositions against four of Cristal’s key European patents, covering areas from production of titanium dioxide from ore to pigment products having commercially valuable properties. After multiple hearings before the EPO Opposition Divisions and Boards of Appeal, this series of oppositions finally came to a successful close in February 2016, with all four of Cristal’s patents being maintained in the form as granted.
