{Also, a company can't invoke ownership rights selectively. If they are going to invoke ownership rights, they must do so for all instances that they are aware of, or risk losing all ownership rights.} Jcleaver, I believe you are wrong there. It is my understanding that the owner of a copyright CAN selectively decide how and to whom they grant usage rights. If I give permission to Joe Blow to use Dina's mesh in any way he sees fit, that right is granted to him and him alone. It does not automatically grant everyone the rights to use Dina's mesh. The only way that would happen is if I specifically stated that everyone had the rights to use it. You may be confusing copyright with trademark. If the owner of a trademark doesn't vigorously defend it, they may lose it. That isn't the case with copyright.
