物质的医药用途发明是一种方法发明,其权利要求属于方法类型,应从方法权利要求的角度来分析其技术特徵。通常能直接起到限定作用的是原料、制备步骤和工艺条件、药物产品形态或成分以及设备等。对于仅涉及药物使用方法的特徵,如果这些特徵与制药方法之间并不存在直接关联,其实质上属于在实施制药方法并获得药物后,将药物施用于人体的具体用药方法,与制药方法没有直接、必然的关联性。这种仅体现于用药行为中的特征不是制药用途的技术特征,对权利要求请求保护的制药方法本身不具有限定作用。

Such features, which are manifest only in the behavior of the drug, are not technical features of the pharmaceutical use and do not have a limiting effect on the method of pharmacy claimed by the claims.
