Guernsey Trademark Registration

The rights to a trademark in Guernsey are granted to the person or company that first uses it in this territory. Although registration is not mandatory, it is highly recommended to demonstrate clear ownership, avoid future conflicts, and defend against trademark infringement.

Trademark applications are filed with the Intellectual Property Office of the Bailiwick of Guernsey.

If you register a combined trademark (word + figurative elements), the exclusive right applies only to the exact configuration filed. If you wish to protect the word or figurative elements independently, additional applications are recommended.

There are no specific documents required beyond the trademark, applicant information, and goods/services list.

If the office eventually requires additional documents—such as clarifications or supporting materials—we will notify you immediately and guide you through each step.

The average processing time is 12 months for straightforward cases. This estimate may vary depending on the circumstances, including objections or third-party actions.

Registered trademarks in Guernsey are valid for 10 years from the application date and can be renewed indefinitely in periods of 10 years.

Renewal can be requested within the six (6) months before the expiration date, or during the six (6)-month grace period following it, subject to late fees.

Yes. If a third party intends to register or use a trademark for similar goods or services that includes a primary or distinct portion of your mark, you have the right to oppose the application based on confusing similarity.

Oppositions must be filed within 20 days after publication. The chances of success depend on the particular circumstances of each case.

Trademark rights in Guernsey are based on use. Although registration provides significant protection, prolonged non-use may weaken your position in potential disputes or challenges.
