As explained below, this image is in the public domain (at least in the USA, and probably also in most other contries) to the best of my knowledge.

I created this image of the UC Irvine seal by slightly modifying the general University of California seal at File:The University of California 1868.svg, which, as explained on its description page, is in the public domain (at least in the USA, and probably also in most other contries). In order to create the UC Irvine seal, I replaced the text .1868. by IRVINE, and I changed the color from black to UC Irvine Blue (002244 in HTML rgb notation). I think that these modifications do not meet the threshold for copyright protection, but in case that I have any copyright on the changes which I did, I hereby release into the public domain any copyright which I might have on this image. So now also this UC Irvine seal is in the public domain (at least in the USA, and probably also in most other contries) to the best of my knowledge. But please remember that even if this picture is in the public domain (meaning that it is not protected by copyright laws), its use might still be restricted due to trademark protection or similar laws.
