Extracts and compounds of natural products have potential as alternatives to current Western medicines. However, these products may not be patentable under the statutory requirements because of their naturally-occurring nature. This article analyzes the current patenting practices for natural products in the United States, particularly in light of the recent Supreme Court ruling in Myriad, and suggests an advantageous strategy for patenting these products. Briefly, isolated natural products per se are not patentable in the United States. Therefore, patenting focus should be placed on the modification, formulation, manufacture, and application of natural products. A detailed description of each invention is highly recommended for stronger support and broader coverage of the claims.
天然产物的提取物和化合物具有替代当前西药的潜力。然而,由于其天然存在的性质,这些产品可能不符合法定要求而无法获得专利。本文分析了美国当前的天然产物专利实践,特别是鉴于最近美国最高法院在 Myriad 一案中的裁决,并为这些产品的专利提供了有利的策略。简而言之,在美国,单独的天然产物本身是不可专利的。因此,专利重点应放在天然产物的修饰、配方、制造和应用上。强烈建议对每项发明进行详细描述,以更有力地支持和更广泛地涵盖权利要求。
