The issue of how the laws of copyright affect origami diagrams and models is an important one. Groups such as the Origami Artists and Creators are working towards an internationally agreed set of guidelines. Dr. Robert Lang has presented his interpretation on his website. Until a common statement is agreed, we refer people to the terms in our constitution.
(1) The Society and its Members shall respect all copyrights, registered trademarks and registered designs in all models, designs, diagrams, photographs, books and writings and shall observe the laws of copyright, registered trademarks, registered designs and patents and all other provisions relating to intellectual property which are applicable in all the separate countries throughout the World.
(2) This article shall apply to all models, designs, diagrams, photographs, books and writings
whether existing in writing or print on paper or any other hard copy or existing in electronic form, photocopy or microfiche in libraries, public or private archives or on the internet or on recorded discs or tapes of any kind or in any other kind of electronic record and whether made commercially or otherwise publicly or made privately.
(3) Before reproducing any model, drawing, photograph or text contained in any publication, a member of the Society shall obtain the consent of the copyright owner before publication.
(4) As a matter of courtesy, whether or not required to do so by law, the Society and its Members shall give proper acknowledgement to the original author of any model, design or diagram demonstrated or reproduced in any manner.
