An introduction to a subject that continues to grow as an important academic subject. The authors provide an overview of the legal framework of intellectual property, concentrating on topics of particular practical importance and interest. They give full coverage of points which are subject to rapid technological change, and discuss those twilight areas where the law is nebulous and unformed. This new edition includes all recent developments, including the EU programme of harmonizations of copyright, the Trade Mark Act 1994, and cases dealing with the patenting of life forms.
