Since the implementation of Directive 2004/48 EC on the Enforcement of Intellectual Property Rights in Sweden there is today a possibility for pharmaceutical companies holding a patent to issue interim injunctions against a generic company on the grounds of an attempt or preparation to a pharmaceutical patent infringement. It has been shown that one of the earliest steps in which a generic company may infringe a pharmaceutical patent is to offer the generic drugs onto the market. However, since the implementation of the attempt and preparation rule in the Swedish Patent Act questions have been raised as to in what stage interim injunctions may be issued against an attempt or preparation to offer generic drugs onto the market made by generic companies. This thesis has therefore intent to investigate at what stage interim injunctions may be applied for against a generic company on the grounds of an attempt or preparation to offer generic drugs. In the thesis the writer argues that in order for an attempt or preparation to offer generic drugs to exist an overall assessment must be made of the particular situation and that there is no specific principles to follow in order to determine either an attempt or a preparation to offer generic drugs. However, some guidance might be brought from Danish case law in order to establish a preparation to offer generic drugs in Sweden.
