chad, Free & Public Domain are two completely different things. There are only 2 ways something can be considered Public Domain... 1st) 75 years have passed since the creator's death (& even then trademark restrictions may apply) or 2nd) The creator must specifically state "I relinquish all rights to this work & place it into the public domain" or words to that effect. Copyright cannot be lost through neglect, it must be given away.
