专利号不仅仅是一个数字编码,从专利号上是可以观察到许多特征的。

识别这些专利号有什么用呢?其实对于专利分析而言是非常有用的。
例如,DERWENT中是有专利家族的,很多人并不能很清晰的判断这些专利号,那么他分析结论的可靠性就大打折扣了。
以下是DII数据中的一项专利,其中包含的专利家族信息如下:US2005105867-A1; WO2005053116-A2; EP1687874-A2; AU2004310694-A1; CN1883085-A; JP2007511919-W; US7403689-B2; TW200532267-A; WO2005053116-A3
上面的数字看起来很乱,但又有一定的规律。
例如,该专利家族分别在:US、WO、EP、AU、CN、JP、TW申请了专利,说明该专利的申请范围很广。
其中,获得授权的国家和区域是:US7403689-B2;EP1687874-A2;JP2007511919-W说明该专利是一项三国专利。
但是,有人又问为什么有的国家有两个号,而有的国家仅有一个号呢?
EP1687874-A2 Based on Patent WO2005053116;
EP1687874-A2 PCT application Application WOUS038982;
AU2004310694-A1 Based on Patent WO2005053116;
JP2007511919-W Based on Patent WO2005053116;
JP2007511919-W PCT application Application WOUS038982
根据这条信息可见,该专进入到了PCT程序,所以,会导致有的国家仅有一个授权号。
先写到这里,以后再补充。
