Trade Marks

A trade mark is a sign that, when associated with a product, distinguishes it from similar competing products. This may be words, a logo or a combination of the two.


With effect from 1 March 2012, the Intellectual Property Office took over the responsibility for the registration and administration of patents and biotechnological inventions from the Greffe.

Image rights

Image rights are the expression of a personality in the public domain. The provision of image rights in law enables the definition, value, commercial exploitation and protection of image rights associated with a person.


A registered design protects the visual appearance of a product or item and gives you exclusive rights for that appearance to the extent that, if necessary, there is a legal right to stop an unauthorised party from producing or using your design.

Unregistered Rights

There are a wide range of intellectual property rights for which protection is given under law in the Bailiwick of Guernsey.

Introduction of registers of trade mark agents and registered design agents

The outcome of the consultation was a recommendation to the Committee for Economic Development to introduce a register of trade mark agents, and a register of design right agents. New regulations relating to trade mark and design rights agents were made on 23 February 2017, and came into effect on 1 April 2017

The regulations are available to view in the Law & Practice section.
