"If the people who made the items don't fight it now, they will lose the copyright"

While this is true of trademarks it doesn't apply to copyright. I kludged together a couple of answers from the copyright forum where this has come up before...

Copyright cannot be lost through neglect (see #5 at the link above). It can only be lost through expiration,(currently 75 years after the creators death) or all rights can be given up by placing the item into the public domain (this must be done specifically by the person who originally held the copyright).

This from http://www.bloodletters.com/copyright.shtml...

"Copyright is never accidentally lost. You don't have to worry about losing your copyright by not defending it, as happens with trademarks. You can only explicitly give it away, by selling certain rights to a publisher, or by releasing it to the public domain, which you do by explicitly stating on the document something like, "I hereby release this work to the public domain."
