在手工制造产品时期,要生产一个复制品差不多同生产一件原物一样昂贵。而在工业生产中,若无原物,则一个新产品的设计常常具有极高的商业利益。产品的日益丰富也使更多的人不仅要求一件产品具有实用性,而且也要求它具有艺术感染力。于是模仿他人的工业外观设计便成了既是经济问题,也是法律问题。 In hand-made products, it is almost as expensive to produce a duplicate as an original. In industrial production, without the original, the design of a new product often has a very high commercial interest. More and more products also make more people not only require a product is practical, but also requires it to have artistic appeal. Industrial designs that imitate others have therefore become both economic as well as legal.
