Try, Try, again.
Having nearly completely destroyed the market for Music CD's, the Brian Trust at the RIAA is trying now to patent a very scientific method of identifying 'authentic' CD's. Should be a useful technique for the distributors' auditors to inventory the unsold CD's at the warehouse so they can be written off.
"Using mass spectrometry, specific types and/or quantities of isotopes of each tracing substance, on a structural level, are used to indicate a specific marking and product identity characteristics, such as a specific lot number, batch number, manufacturer identity, shipping date and the like. The security marking is preferably invisible to the naked eye. The security marking technique is also useful for tracking, authenticating and quality control purposes"
United States Patent Application 20050190677

We have not figured out if fighting the RIAA is worth the trouble, as they seem to be doing a great job of destroying their own business, but if one was interested in contesting the patent application, the IdeaCop(tm) has come up with some potential prior art references in the attached file for your collective review.
Post your comments and alternative references. Help the USPTO do its job!
