These are the slides of a presentation to solicitors, barristers and others at 4-5 Gray;s Inn Square on 26 June 2013. It defines intellectual property ("IP") as the legal protection of intellectual assets ("IA") which are the brands, designs, technology or creative works that give a business a competitive advantage over its rivals. The study discusses how the law protects each of those assets: brands by designs, passing off, geographical indications and registered designs, for example,. and technology by patents, the law of confidence, unregistered design right, plant breeders rights and copyright. However, IP rights create monopolies and restraints of trade that are as harmful as any other. The law that creates these rights also regulates their subsistence and exercise. Thus, IP law strikes a balance between two conflicting interests: that of incentivizing creativity and innovation against promoting competition and freedom of trade. The tension between those two public interests has always existed and its appreciation is fundamental to understanding IP law. One instance where it appeared was in the Uruguay Round of negotiations of trade liberalization between 1986 and 1994 which led to the WTO agreement and TRIPS. Since 1994 IP protection has been one of the conditions of access to the markets of the leading industrial countries. TRIPS refers to four core treaties - Paris, Berne, Rome and Washington. These are the general protection treaties. Others, such as the PCT, Madrid and Hague, facilitate multiple patent, trade mark and registered design applications. There are classification agreements like Nice and Locarno and regional agreements like the European Patent Convention. The presentation considered the harmonization of European copyright, registered design and trade mark law and the Community trade mark and Community design regulations. It identified the core British statutes: the Patents Act 1977, Copyright, Designs and Patents Act 1988, the Trade Marks Act 1994 and the Registered Designs Act 1949. It discussed also some of the more important secondary legislation such as the Patents, Trade Marks and Registered Designs Rules. Finally, it identified some of the sources of law in print and on the internet listing the materials that can be downloaded from the IPO, EPO, OHIM, WIPO and other sites.
