royalty turnstyle counter to me:

"Our intellectual property continues to expand as we recently received a notice of allowance from the United States Patent and Trademark Office for our patent application titled System and Method for Managing Information Stored in Semiconductors. The allowance of this patent along with a recently filed continuation, serves as the foundation of our new MicroSignet™ patent portfolio. The technology allows naturally occurring defects introduced in the semiconductor fabrication process to be used as a 'fingerprint' unique to each integrated circuit. As some of these faults are transient, these 'fingerprints' cannot be copied. So, every device in a system becomes part of rights management and data security. We believe this portfolio will be attractive to manufacturers of semiconductors. This is the third significant technology portfolio now including Flash-R, Nunchi®and MicroSignet IP and related patents.
