Patents: In addition to local registration, if you apply for a patent based on an existing United Kingdom (UK) patent, at any time after the UK date of issue, registration will normally be granted, the patent will expire with UK patent.
EP(UK): If you apply for a patent based on an existing EP (UK) patent, at any time after the EP(UK) date of issue registration would normally be granted, the patent will expire with EP(UK) patent.
Trade marks: In addition to local registration, only the registered owner, or a person deriving a right from the registered owner, of a UK registered Trade mark (TM) may apply for registration based on a UK trade mark. Applications can be at any time during the life of the UK trade mark and will expire with UK trade. Revised law is under discussion, but no clear plans for introduction at present. Community Trade Marks (CTMs) do not have effect in Guernsey.
Changes to the CTM regulations in 2004 now allow for CTM applications from Guernsey to be accepted by OHIM.
Designs: In addition to local registration, application may be made at any time during the life of the UK Design.
Under a Protocol to the UK's Act of Accession to the EC the Channel Islands are part of the European Communities for customs and trade purposes, but the provisions on free movement of workers, freedom to provide services, and freedom of establishment do not apply.
