第87条优先权

（1）任何人在或向：

（a）任何保护工业产权的巴黎公约缔约国或

（b）世界贸易组织成员

正式递交的专利申请、实用新型或者实用证书，该任何人或其继承人为了递交关于相同发明的欧洲专利申请的目的，自首次申请的申请日起12个月内，应当享有优先权。

（2）根据做出申请的申请国的国内法、双边协议或者包括本公约在内的多边协议，相当于正式国内申请的任何申请，应当被视为能够产生优先权。

（3）正式国内申请是指能够确定申请日的任何申请，不论该申请的结果如何。

（4）如果在后续申请递交之日，在先的首次申请已被撤回、终止或驳回，而没有供公众查阅，没有产生任何权利，也没有作为优先权的基础，那么与在先申请的客体相同并且在同一个国家或者向同一个国家递交的后续申请，在确定优先权时，应当视为首次申请。此后，在先的申请不得再作为要求优先权的基础。

（5）如果首次申请不是向遵守保护工业产权的巴黎公约或者建立世界贸易组织协议的工业产权机构提出，而根据欧洲专利局局长的公告，该工业产权机构承认在与巴黎公约规定的相同条件和效力下给予在欧洲专利局的首次申请以优先权，应当适用第1-4款。

第88条要求优先权

（1）若申请人希望利用在先申请的优先权，应当根据实施细则的规定递交优先权声明和其他文件。

（2）欧洲专利申请可以要求多个优先权，该多个优先权可以来自不同的国家。合适时，任何一个权利要求可以要求多个优先权。要求多项优先权时，优先权期限应从最早的优先权日起计算。

（3）如果欧洲专利申请要求了一个或多个优先权，优先权应当仅覆盖申请中被包含在优先权申请中的那些特征。

（4）若要求了优先权的发明中存在在先申请的权利要求中不存在的某些特征，除非在先申请总体上明确地公开了这些特征，该发明才能享有优先权。
