To answer this question, we must first determine whether the Forbidden City has the right to publish jewelry styles. I don't think so, although the Forbidden City has photo rights. So there is no problem of infringement. If your question is "from plane to three-dimensional", does it constitute duplication in the sense of copyright law? Then, the current judicial practice believes that for works of art, from plane to three-dimensional, it has constituted a copy. Guangzhou Yuexiu District Court 20 13 has a case in which a manufacturer produces other people's jewelry designs, which constitutes copyright infringement.
