问:已授权的欧洲专利年费缴纳情况如何查询?
答:如果通过European Patent Register查询欧洲专利的法律状态(Legal status),欧专局会在显示查询结果的网页上给出下列提醒:
"The EPO does not accept any responsibility for the accuracy of legal status data relating to the post-grant phase, including but not limited to their completeness and fitness for specific purposes, nor can it guarantee that such data are up to date. For authoritative information, please refer to the relevant national patent authority."
所以,如果要查询授权以后(post-grant phase)的准确的法律状态,应该去各个成员国的登记簿(Register)查。
德国专利商标局的Register网址为http://register.dpma.de,该网站有英文版,而且可以直接输入欧洲专利号来查询。
