Where a substance or composition is already known to have been used in a ‘first medical use’, it may still be patentable for any second or further use, provided that said use is novel and inventive. This is an exception from the general principle that product claims can only be obtained for (absolutely) novel products. ‘Second Medical Use’ patents are an important component of the potential second-line patent protection.
Most readers will know that so-called Swiss form claims (“Use of drug X in the manufacture of a medicament for the treatment of disease Y”) were first proposed by the Enlarged Board of Appeal of the EPO in the EISAI case back in December 1984 to allow new uses for known drugs to be patented….
Regular readers of the Kluwer patent blog may recall that in April 2014, the English Patents Court revoked two patents relating to trastuzumab, the active ingredient in Herceptin, which is marketed outside of the US by Roche.
