The development of pharmaceutical and biotechnology industries indicates that people around the world use different types of drugs for disease treatment and prevention. In the case of high demand for medicines, great attention to pharmacy industry is paid. Since the drugs are directly linked to human health and life, the state pays special attention to the safety of medicines and the quality of eligibility. Therefore, the companies wishing to become a part of this area are to obtain and then keep the license. The protection of intellectual property allows companies to use substantial investment in new drugs and treatment methods and to conduct research in the future. This is a particular concern for originator companies. Undefended patents also inhibit the creativity of local people as local innovators know that their products can be immediately copied, thus discouraging investment in new investigation.
