While this is true of trademarks, I believe it applies to copyrighted material also. It use to be that we couldn't pattent computer software algorithms. Thus we took copyrights out on the material, the problem was that copyrights are still fairly weak and if you didn't fight when someone overstepped you risked losing your rights to the material.

Of course if anyone even wanted to use my copyrighted material anymore I'd think them daffy.
