Design patent


In the United States, a design patent is a form of legal protection granted to the ornamental design of a functional item. Design patents are a type of industrial design right. Ornamental designs of jewelry, furniture, beverage containers (Fig. 1) and computer icons are examples of objects that are covered by design patents.

A similar concept, a registered design can be obtained in other countries. In Kenya, Japan, South Korea and Hungary, industrial designs are registered after performing an official novelty search. In the countries of the European Community, one needs to only pay an official fee and meet other formal requirements for registration (e.g. Community design at EUIPO, Germany, France, Spain).

For the member states of WIPO, cover is afforded by registration at WIPO and examination by the designated member states in accordance with the Geneva Act of the Hague Agreement.

A US design patent covers the ornamental design for an object having practical utility. An object with a design that is substantially similar to the design claimed in a design patent cannot be made, used, copied or imported into the United States. The copy does not have to be exact for the patent to be infringed. It only has to be substantially similar. Design patents with line drawings cover only the features shown as solid lines. Items shown as dotted lines are not covered. This is one of the reasons Apple was awarded a jury verdict in the US case of Apple v Samsung. Apple's patent showed much of their iPhone design as broken lines. It didn’t matter if Samsung was different in those areas. The fact that the solid lines of the patent were the same as Samsung's design meant that Samsung infringed the Apple design patent.
