A bigger question now might be WHY would somebody re-patent the tinfoil phonograph? Ego? Because he can?
Does anybody know if Carl Mohrin is a collector / dealer / researcher??? It might be interesting to hear his side of the story. Sounds like an article for the Soundbox!

Sounds like > an article for the Soundbox! My guess is an educational toy and/or to be used in science classes? He at least must have thought there is some profit to be made in the idea. Any manufacturer could plop out "educational" phonographs based on Edison's expired patent(s). I must say his idea is certainly novel... but I wouldn't think it would work all that well. BTW, you can't re-patent an expired patent, but the patent office does seem to patent first and let others scratch their heads afterwards. I know several computer software related patents have been revoked on challenge recently. You think a 2001 phonograph patent is goofy... how about the 90 or so wheel patents that are approved yearly! http://www.washingtonpost.com/wp-dyn/content/article/2005/11/24/ AR2005112401003.html Loran
