Representatives may be authorised either by individual authorisation or by general authorisation. An extra authorisation is needed for all proceedings relating to a Unitary Patent. In particular, an authorisation for all proceedings established by the EPC does not cover the proceedings relating to a Unitary Patent. Accordingly, a separate check box has been added to Forms 1003 (individual authorisation) and 1004 (general authorisation) which can be used to issue authorisation covering all proceedings relating to a Unitary Patent. Furthermore, new Forms 7003 and 7004 provide, respectively, for an individual and a general authorisation with respect only to a Unitary Patent. When filing Form 7000 (request for unitary effect), it is possible simply to refer to a previously filed specific or general authorisation, if it also covers proceedings relating to Unitary Patents .
