This Practice Note compares patents, supplementary protection certificates (SPCs), trade secrets, copyright, database rights, design rights, trade marks and causes of action in passing off by reference to the following factors: how protection arises, what is protected (including, eg originality/novelty requirements), duration of protection, territory, ownership, infringement, defences to infringement, and threats provisions. It then considers the key advantages and disadvantages of each IP right. This Practice Note focuses on the IP rights which provide protection in the UK. Following Brexit, the UK is no longer part of the EU trade mark (EUTM) or EU designs regimes. These are regimes which provide for unitary IP rights covering the EU Member States. However, as explained in detail below, provision has been made for comparable rights to be created in the UK. This Practice Note does not cover the EUTM and EU designs regimes in detail. For more information, see: Trade marks (EU Law)—overview and Designs (EU Law)—overview. For more information about the impact of Brexit on the trade mark and designs regimes, see Practice Notes: Trade mark rights
