化学分析方法权利要求撰写技巧

化学分析方法专利作为一种方法专利,其保护本身就不如产品专利的"绝对保护"有效,加之方法的使用多在企业内部进行,侵权认定很是困难。因此权利要求文字撰写的质量,直接关系着专利权人的利益能否得到保障。文章列举了分析方法专利申请在权利要求撰写方面存在的典型问题。对实际案例的技术特征进行划分,解析了分析方法专利侵权认定判定过程中的全面覆盖和等同两大原则与技术特征之间的关系。针对该类专利申请体积、质量参数多,酸碱条件多,加热、升温、冷却过程多,操作步骤多和计算公式多等特点,指出实际案例的独立权利要求和从属权利要求,阐述了专利申请中参数很多的情况下说明书具体实施方式的撰写要求,同时说明了对一种权利要求修改时容易导致超范围的情况。

Writing Skills on Claims of Chemical Analysis Method Patents

It is more difficult to protect the patent of chemical analysis methods, than it is for actual products, as they are akin to a process patent. Since chemical analysis methods are generally developed in the workplace, it is difficult to establish identity. Therefore, the identification of infringement to chemical analysis methods patents is also difficult. In this case, the writing quality of claims will directly affect whether the patentee's benefit can be protected. In this paper, several typical problems in the claims of chemical analysis methods patent will be illustrated. Also, all the principles and doctrines of autogenesis for the identification of infringement will be highlighted. According to the many requirements of volume, weight, acidity, alkaline, heating, cooling, operation procedure and formula, we demonstrate both independent claims and dependent claims for a real case step by step, pointing out the requirements of embodiment with a large number of parameters, and indicating the situation when the amendments of requirements easily go beyond the scope of the claim.
