在http://ep.espacenet.com/advancedSearch?locale=en_EP上高级检索,
如果不注明公开文献的国别,选择worldwide,进行检索时结果:
同族专利是检出一篇还是所有的都检出?只检出一篇的话,优先出现的是那篇?还是随机?有漏检的可能吗?
下面是一个检索实例,检索结果无法对应,因批量下载担心漏检,请高手支招,还是没有办法只能一个个国家检索:
A、11 results found in the Worldwide database for:
\"construction machines\" in the title or abstract AND \"ZAHNRADFABRIK FRIEDRICHSHAFEN\" as the applicant
B、9 results found in the Worldwide database for:
\"construction machines\" in the title or abstract AND US as the publication number AND \"ZAHNRADFABRIK FRIEDRICHSHAFEN\" as the applicant
C、3 results found in the Worldwide database for:
