How do I register a patent in Guernsey ?

A patent can only be registered in the Bailiwick provided:

1. it is registered in an overseas jurisdiction in accordance with the laws relating to patents in that jurisdiction;

2. the overseas jurisdiction is one included in Schedule 2 of the Registered Patents & Biotechnological Inventions (Bailiwick of Guernsey) Ordinance 2009 (see document available to download below detailing the jurisdictions included in this schedule).

Except in the case of persons who are ordinarily resident in the Bailiwick of Guernsey, applications to register patents, change particulars, asssign or license patents etc CAN ONLY be made by a registered patent agent (referred to as patent attorney in the regulations). Agents must have a place of business in the Bailiwick as well as meet qualifying criteria determined by the Registrar. Full details can be downloaded below. 

Please note: for 6 months with effect from 1 March 2012, transitional provisions apply which will enable Bailiwick Advocates to continue to make patent submissions without the need to be a registered patent agent. Please see the guidance note below for full details.
