版权符号

The copyright symbol, or copyright sign, © (a circled capital letter "C"), is the symbol used in copyright notices for works other than sound recordings (which are indicated with the ℗ symbol). The use of the symbol is described in United States copyright law, and, internationally, by the Universal Copyright Convention. The symbol is widely recognized, but under the Berne Convention is no longer required to obtain a new copyright in most nations. For instance, the United States eliminated the copyright symbol requirement as of March 1, 1989, but its presence or absence is legally significant on works published previously.
