本文从“歼10模型案”出发,认为应当将著作权法不保护实用功能的原则作为对权利范围的限制,而非实用艺术作品的构成要件。同时,现行法对作品类型的具体列举不应构成对作品外延的严格限制,飞机外形在现行法下宜解释为美术作品。设计图、原型机、模型应属于同一作品。 Based on the “F-10 model case”, this article holds that the principle of the copyright law that does not protect practical functions should be regarded as a limitation on the scope of rights, not a constituent element of practical works of art. At the same time, the specific enumeration of the type of work by the current law should not constitute a strict restriction on the extension of the work, and the aircraft shape should be interpreted as a fine work under the current law. Design drawings, prototypes, models should belong to the same work.
