論著作權法功能性原則之理論與實踐

所謂功能性原則，係指著作權不保護功能性作品之功能性部分，僅保護作品中能與功能性部分區分之非功能性或藝術性表達部分。許多作品於創作當下，除因實用之考量而具有功能性外，創作者同時於作品中投入個人思想與感情，形成具藝術性或非功能性之表達，導致作品內含功能性與非功能性二項特徵。原按著作權法之原理，作品若含原創性之表達，應受著作權之保護。然而，若未界定權利範圍，恐使著作權之保護及於作品中原為著作權所排除，屬於技術思想而歸專利權保護之功能性部分。此時，功能性原則即扮演框限功能性作品中著作權所及之範圍，確保功能性部分不具可著作性之關鍵角色。美國作為功能性原則之源流國，於電腦程式、實用物品以及建築物等功能性作品領域之實務方面已累積相當之經驗，且已建構功能性原則應用之準則。近年我國實務於相應領域明顯有引進美國功能性原則及其應用標準之現象，惟文獻或論述甚少談及功能性原則之相關概念。有鑑於此，本文欲從美國關於功能性原則之基本概念出發，觀察美國實務應用該原則所產生之判準、爭議與值得思考之處，於介紹我國實務相應之進展後，藉由比較之方法探尋我國關於功能性原則之問題，進而提出本文之觀點與建議。

Functionality doctrine, also known as the doctrine of separability, is a principle of copyright law which says the law protects the artistic or nonfunctional features of a functional work which are separable from the functional aspects of the work. The law's notion of functionality, in contrast, precludes the functional features of the work from gaining copyright protection. A functional work would unquestionably have its intrinsic function due to the utilitarian consideration. In the creation of the work, the designer would also put her idea and feelings into the work to form the aesthetic or non-functional expressions. Thus, a functional work would have two major features, functional and non-functional. In accordance with the fundamental of copyright law, a work is copyrightable if original expressions contained. If the extent of copyright has not been firstly defined, however, there will be a risk that the copyright protection will extend to the functional aspect of the work which should be secured by patent. In this case the functionality doctrine will play a crucial role to limit the scope of copyright protection, and ensure the functional features of a functional work stay uncopyrighted. The U.S., as the origin of the functionality doctrine, has accumulated considerable experience in applying the doctrine to the judicial cases on copyrightability of varied functional works, such as computer program, useful article, and architecture. Taiwanese courts have adopted the functionality doctrine for deciding copyrightability of computer program and useful article in recent years. Treatises and literatures in Taiwan, nevertheless, have rarely discussed or even mentioned the concept of the functionality doctrine. In the light of this, the article will review the judicial application of the functionality doctrine in the U.S. after a thorough introduction to the basic concept of the doctrine. Following the observation of Taiwanese courts' reaction on the functionality doctrine, this article will try to provide some useful comments and workable suggestions by making a comparative study on the U.S. legal experience.
