Company name change due to legal concerns Kristiansen's company, Earthtree Pte Ltd, was originally known as Einstein's Earthtree Pte Ltd. However, lawyers from The Roger Richman Agency, on behalf of The Hebrew University of Jerusalem, issued warning letters to protect the image and identity of Albert Einstein. The lawyers also contested his use of the moniker "Einstein Kristiansen", and so in 2007, he changed his professional name back to his original name, Øistein Kristiansen.
