[Biotechnological invention patents: a legal-economic analysis]

Not without controversy, patents have traditionally been considered as elements which stimulate and protect inventive activity.

After concluding that current intellectual property laws do not come out clearly against the protection of biotechnology inventions, we then review the proposals for European Union regulation in the form of a directive which would clarify patenting possibilities.
