On this day, 27 years ago, July 4, 1998 (May 11, 1998, the 1998 lunar calendar), the British authorities refused to register the portrait of Consort Di as a trademark. On July 4, 1998, the British Government Patent Office recently decided that the portrait of the late Princess Diana belongs to the public and cannot be registered as a trademark. The "Diana Memorial Foundation", a charity established after Princess Diana's death, filed an application with the British Patent Office seven months ago, requesting to register the 26 most widely circulated portraits of Princess Diana as trademarks. According to analysis, the foundation wants to Through this move, obtain copyright to Princess Diana's portraits and receive a high profit share from the manufacturers of goods bearing Princess Diana's portraits. However, the Patent Office rejected the application in accordance with relevant British laws, arguing that the portrait of Princess Diana has no special connection with any specific commodity, cannot be used as a trademark, and should not be monopolized by this foundation or other relevant institutions. British government sources believe that this dispute involving the copyright of Princess Diana's portrait is of typical significance. If the application of the "Diana Memorial Foundation" is approved, it will cause more celebrities to make similar requests to prevent their names and portraits from being used by others without authorization.
