Font content consists of a series of characters with a unified appearance style. Although the structure of Chinese characters is fixed, it has great creative space for the appearance style factors that determine the font style, such as stroke shape, stroke proportion, component distribution, character proportion and so on. As long as the appearance style is quite different from the existing font style, it should be regarded as an original achievement. From the symbolic form, the characters in the font have the characteristics of works of art and should be protected by the intellectual property rights of the types of works of art. A font composed of a series of characters is a family art work with similar characteristics. However, the whole font collection should not be regarded as an assembly work, because the key to constitute an assembly work lies in the selection and arrangement of its components. The font must meet the national standards and cannot be selected and arranged, so it is impossible to constitute a unique assembly work. This also shows that the originality of the font set lies not in the arrangement, but in the originality of the appearance of some words.
Font library software converts fonts containing a certain style into codes for storage and calling, and should be protected as computer software.
