Patents in green biotechnology in Europe and the United States of AmericaThis thesis explains the legal situation regarding inventions in the field of green (agriculturally used) biotechnology in Europe and the United States of America. After an introduction into biological basics and a short overview of general patent law, this paper gives answers to all legal questions concerning patenting in green biotechnology and shows the current legal situation. The European laws reviewed in this thesis the Directive 98/44/EC (Directive on the legal protection of biotechnological inventions) and the European Patent Convention. The most prominent American law reviewed in the paper is Title 35 United States Code, which is the legal basis for patents under United States Federal Law. The recent U.S. patent reform-, America Invents Act of 2011, is also part of the legal analysis. The jurisprudence of the ECJ, the EPO and United States courts completes the description of the legal situation. As a necessary excursus, the paper covers related intellectual property laws (plant variety protection in Europe and the U.S.). Because of the border crossing impact of intellectual property protection in this field, the paper also contains an illustration of the general problems of European Patent Law (EU Patent, language difficulties).In addition to an illustration of the legal situations, the thesis also makes a legal comparison between the European and the US legal situations.
