Clovis Oncology has announced that the European Patent Office (EPO) last week upheld claims of European Patent 2534153 in amended form covering certain crystalline forms of rucaparib camsylate, including rucaparib S-camsylate Form A, the crystalline form in Rubraca.
In its oral decision announced at a hearing on 4 December, the Opposition Division upheld claims, narrowed from the originally granted patent, to certain crystalline forms of rucaparib camsylate. These forms include, but are not limited to, the commercial product. The European Opposition Division found patentability of the claimed forms based on the inventiveness of these crystalline forms and a constellation of unexpected properties.
Richard Clegg said, “This is a great result for Clovis Oncology and one that acknowledges the innovation behind Rubraca. We are delighted to have been able to ensure the continued success of this ground-breaking cancer treatment.”
