Field of Application
A design is a commercial property right especially targeting esthetical forms of a product. In general, any design of any product can be protected, if the design can be represented by a two or three dimensional appearance.

Pure technical features (-> patent, -> utility model) as well as designs which do offend against public policy and morality.

The design has to be globally new and original on the filing date. It has to exceed the average performance of a designer.

Novelty Grace Period
In contrast to a patent which has to be globally new at the filing date, for designs there is a novelty protection ("grace") period of 12 months for the applicant's own publications.

Maximally 25 years.
