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 (see 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 OHIM, 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.

Protections

Apple v Samsung showing the effect of solid and broken lines on infringement 1

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.2 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.1

Computer images

Both novel fonts and computer icons can be covered by design patents. Icons are only covered, however, when they are displayed on a computer screen, thus making them part of an article of manufacture with practical utility.3 Screen layouts can also be protected with design patents.4

Publication of application

In China, Canada, Japan, South Africa, and the United States,5 a design patent application is not published and is kept secret until granted.

In Brazil, the applicant can request that the application be kept in secrecy for a period of 180 days from the filing date. This will also delay the prosecution and granting of the application for 180 days.

In Japan, an applicant can request that a design be kept secret for a period of up 3 years after the registration has been granted.

Notable design patents

Comparison to

Utility patents

US utility patents protect the functionality of a given item. Providing the maintenance fees are paid, utility patents are generally valid for up to 20 years from the date of filing (with some exceptions).9

Design patents cover the ornamental nonfunctional design of an item. Design patents can be invalidated if the design has practical utility (e.g. the shape of a gear). Design patents are valid for 14 years from the date of issue.10 There are no maintenance fees.

Copyright

Copyright prevents nonfunctional items from being copied. To show copyright infringement, the plaintiff must show the infringing item was copied from the original. The copyrighted artistic expression must either have no substantial practical utility (e.g. a statue) or be separable from the useful substrate (e.g. picture on a coffee mug).

Design patents, on the other hand, cover the ornamental aspects of functional items from being infringed. One does not have to show that the infringing item was copied from the original. Thus a design that was arrived at independently can still infringe a design patent.

Many objects can be covered by both copyright and design patents. The Statue of Liberty is one such example.1112

Trademark and trade dress

Trademarks and trade dress are used to protect consumers from confusion as to the source of a manufactured object. To get trademark protection, the trademark owner must show that the mark is not likely to be confused with other trademarks for items in the same general class. The trademarks can last indefinitely as long as they are used in commerce.

Design patents are only granted if the design is novel and not obvious for all items,13 even those of different utility than the patented object. An actual shield of a given shape, for example, can be cited as prior art against a design patent on a computer icon with a shield shape. The validity of design patents is not affected by whether or not the design is commercialized.

Items can be covered by both trademarks and design patents. The contour bottle of Coca-Cola, for example, was covered by a now expired design patent, U.S. Patent D48,160, but is still however protected by at least a US registered trademark. 14
