At present, the space for product appearance improvement in mature industries is very narrow, and local improvement is an important direction for product appearance design improvement, so local appearance design is an important part of modern appearance design protection system. The patent of local design also has its particularity.
Indispensable;
One can't be short of two meanings: ① The structure is inseparable, that is, the partial design of products that can't be divided or sold separately and used alone, such as socks heel, brim and cup handle. (2) The inseparability in use means that for products composed of multiple parts with different specific shapes or patterns, the parts themselves cannot be sold and used separately, for example, a set of jigsaw puzzles composed of plug blocks with different shapes.
2. Comparability;
Comparability means that local design should contain creative units that can be compared with other designs, that is, local design should be an independent design module. Specifically, the local appearance design must occupy a certain physical scope and have a relatively closed area as a whole.
3. Visibility;
Visibility means that design needs to be perceived through vision. Local appearance design also requires visual application or direct determination with naked eyes without special tools.
4. novelty judgment subject;
Novelty mainly examines the same or substantially the same design, and the ability to judge the subject will greatly affect novelty and subsequent confirmation and infringement.
The provisions of patent laws in different countries on the subject of novelty judgment are slightly different, but in principle, they all abstract the actual consumers to make them have special abilities.
5. Clearly distinguish the theme;
The obvious difference mainly depends on whether there is obvious difference between design and comparative design, and tends to have design ability.
