论设计保护的功能性原则

作者：梁志文广东外语外贸大学华南国际知识产权研究院

良善设计是产品取得市场成功的重要因素,在符合知识产权部门法规定的条件下,它分别作为实用艺术作品、外观设计、立体商标(三维标志)、商品外观而得到保护,其共同之处是:不保护功能性的设计。功能性原则是区分设计保护与发明(以及实用新... 详细信息

良善设计是产品取得市场成功的重要因素,在符合知识产权部门法规定的条件下,它分别作为实用艺术作品、外观设计、立体商标(三维标志)、商品外观而得到保护,其共同之处是:不保护功能性的设计。功能性原则是区分设计保护与发明(以及实用新型)专利的基本原则,还是设计受交叉保护的制度依据;但它不应是版权法、专利法、商标法和反不正当竞争法对设计区别保护的标准。功能性原则的具体判断标准必须回应设计产业的创新实践需求,同时,它也不应影响知识产权部门法保护设计的其他条件。应以“技术功能”为标准,在承认设计特征三分法的基础上,确定“功能性和装饰性兼具的设计”受保护的地位,但其保护范围应与装饰性的强弱相关联,以实现激励设计创新的目标。

专利制度需要改革,譬如我国的专利无效程序因其环节多等原因而颇受学者非议。然,专利制度改革需要理论的支持。专利授权行为的性质是专利法中的重要课题,对专利制度的选择具有重要意义。否弃行政许可行为理论,重构专利授权行为理论,认定其为司法性行政行为,这对专利制度改革和实践具有重要意义。

促进科学技术进步和经济社会发展是专利法的终极目标,也是专利制度的主要功能。但是,在我国,专利制度功能的基本构成却常为人们所忽视。创新经济学认为:创新不断扩散,是技术创新社会经济效益的根本来源。《专利法》第26条规定的发明公开制度作为授予专利权的条件之一,对促进技术创新的扩散具有重要价值,体现了专利制度的终极目标。它教导该领域的普通技术人员实施发明(教导功能),体现了发明人真正做出了发明创造(占有功能),促进了技术信息和权利信息的传播(信息传播功能),从而实现增进人类知识积累的专利法目标。从制度功能来看,实现专利制度基本功能的重要载体是专利文献。

TRIPS协议第39.3条首次在国际层面规定了数据保护的义务。我国是否履行了该义务的入世承诺,是中美之间重要的争议。为缓解相关的国际压力,需要构建合理的数据保护制度,梳理世界各国如何实施第39.3条具有重要的借鉴意义。从数据保护的属性来看,包括禁止占用(商业秘密)、数据专有权和市场专有权等立法模式。在具体制度上,依据TRIPS协议第39.3条,各国详细规定药品数据受保护的条件,重点界定新型化学成分与新药的关系及其范围,明确数据保护的权利内容和保护期限,构建保障公共健康的数据保护限制制度。我国应借鉴这些规定,修订《药品管理法》以完善药品数据的保护。

我国新近生效的《网络信息权保护条例》建立了间接侵权制度,它与直接侵权一起构成了版权侵权制度,具有革命性的影响。但《条例》尚无法完全满足数字技术所带来的挑战,这主要集中在法律没有为“双重用途技术”提供普遍化的间接侵权标准。因此,根据我国经济发展之现状,在版权法公共政策目标的指导下,建立以过错为归责原则、以类型化立法为基础的间接侵权制度是具有合理性的。

关键词：间接侵权版权法双重用途技术过错
