>From the Copyright Law FAQ:

A proper copyright notice consists of three things: 1) the letter "C" in
a circle (called, logically enough, the "copyright symbol"), or the word
"Copyright," or the abbreviation "Copr."; 2) the year of first
publication; 3) the name of the copyright owner.  17 U.S.C. 401(b).

(C) and © appear to  be unnecessary if Copyright <year> <name> is
already present. IANAL, side effects may include, not intended to
diagnose, treat, or prevent, etc.
