- Sommaire
1. A change of category after a patent has been granted is admissible, having regard to Article 123(3) EPC, only in exceptional cases.
2. Where the granted patent relates to a method of working, its subsequent conversion into an apparatus patent is such an exceptional case if the extent of protection conferred by the process patent (Article 69 EPC) encompasses the apparatus for carrying out the method of working. However, it is then necessary for the means of carrying out the process to be described in such detail and so comprehensively that an anverage skilled person can, without undue effort, deduce fully and clearly the apparatus suitable for carrying out the protected process from the technical teaching defined in the process patent.
