Book excerpt: 'The art of editing is to bring contributions together, which melt into one book. This is what Emanuela Arezzo and Gustavo Ghidini have achieved with their own critical mind by composing a book of papers, in which internationally renowned experts measure the tensions created for the patent system by the needs and problems of protecting biotechnological and software inventions. All together, they present a comparative law challenge to the very fundaments of patent protection. As such, they are or may become a "must read".' Hanns Ullrich, College of Europe, Bruges, Belgium 'Arezzo and Ghidini have put together a fine collection of essays addressing developments in patent law from general themes to emerging ones in the infotech and biotech sectors. It is notable that the international array of authors includes contributions from both established and rising young scholars, all of them ably tackling difficult issues that merit our attention.' Rudolph J.R. Peritz, New York Law School, US The new millennium has carried several challenges for patent law. This up-to-date book provides readers with an important overview of the most critical issues patent law is still facing today at the beginning of the twenty first century, on both sides of the Atlantic.

From the most controversial cases in biotech to the most recent decisions in the field of software and business methods patent, patent law has tried to stretch its boundaries in a way to accommodate such new and controversial subject matters into its realm. Biotechnology and Software Patent Law will strongly appeal to postgraduate students specializing in IP law, international law, commercial and business law, competition law as well as IP scholars, academics and lawyers.
