After designing the Smiling Sun Logo in April 1975 the artist handed over all copyrights and any other material and immaterial rights to the Logo to the Danish movement against nuclear power, organised within the OOA (Organisation for Information on Nuclear Power).

The OOA decided in 1976 to register the Smiling Sun Logo as a trademark in Denmark and in a range of other countries. Effective from 13th December 2004 the Logo has been registered as EU Community Trademark no. 004193091. As such the logo enjoys full trademark protection in the 27 member countries of the European Union. The OOA Fund is considering protection in some countries outside Europe.

The trademark protection serves the purpose of securing the integrity and independence of the Smiling Sun Logo, to reserve its utilisation to the anti-nuclear power movement worldwide and to enable action to be taken against abuse and alteration of the Logo by commercial interests, against counter use by pro-nuclear power campaigns and against political parties taking possession of the Logo.

All rights of the OOA have after 31st May 2000 been transferred to the OOA Fund, whose primary task it is to secure and maintain the copyright and any other rights related to the Smiling Sun Logo. The  OOA Fund enters into agreements with groups and organisations campaigning against development and use of nuclear power, offering such groups user rights to the Logo.
