Software and business methods patents: <br />Case law evolution and market strategies

In this paper we explore the evolution of the software industry and the increasing importance of patent protection.

These systems, deeply involved in e-business, are perceived, on a legal point of view, in different way sin Europe and in the US and accorded different levels of protection on either side of the Atlantic.

Furthermore, we also focus our attention on the effects of the intense use of industrial property on software and business methods, in terms of innovation, competition and the sharp rise in litigation
