Comparative overview of innovation and patent filings in Radiopharmacy

ABSTRACT Objective To expose the current situation of the Brazilian Nuclear Medicine in relation to innovation, taking into account the Intellectual Property protection and the particularities of this field. Methods The number and the origin of patents filings from Brazil, United States and European Patent Convention countries were retrospectively compared in a 20-year period. Results The number of accumulated patents filings of conventional pharmaceuticals was ten times higher compared to the radiopharmaceuticals in the three regions studied. Conclusion The largest number of Brazilian patents filings corresponded to the international patent applications, which is related to the country development conditions, as well as to the difficulties in the process of patent filing.摘要 研究目的：结合知识产权保护现状与核医学领域的特殊性，剖析巴西核医学领域的创新发展现状。 研究方法：对20年间巴西、美国及欧洲专利公约（European Patent Convention, EPC）成员国的专利申请数量与来源分布进行回顾性对比分析。 研究结果：在上述三个研究区域内，常规药物的累计专利申请量为放射性药物（radiopharmaceuticals）的十倍。 研究结论：巴西提交的专利申请中，国际专利申请占比最高，这与该国的发展国情及专利申请流程中存在的现实障碍密切相关。
