Dear Intarwebs,
"Copywrite"[1] is not a word. You probably, in fact, mean "copyright".
In a similar vein, "copywritten" is not now, has never been, and never will be the adjective form of "copyright". You’re looking for "copyrighted", or just "copyright" (as in "Copyright 2008 J. Random Luser").
No love,
bma
