17. Patentable subject matter

This chapter deals with patentable subject matter and the ways in which it is regulated under the Patents Act 1977 and the 2000 European Patents Convention (EPC). More specifically, it discusses five criteria that an invention must satisfy to be patentable, including the requirement that it must be capable of ‘industrial application’, and that patents are not granted for immoral inventions. The chapter also considers two different approaches that are used when deciding whether an invention falls within the scope of section 1(2)/Article 52(2): the ‘technical effect’ approach in the UK and the ‘any hardware’ approach applied by the European Patent Office. Finally, it examines how the law deals with a number of specific types of invention and looks at possible reforms, particularly in relation to computer programs and computer-related inventions.
