Intel and AMD are also licensees.

"We welcome Schneider Electric as our first European MMP Portfolio licensee," said Mike Davis, Alliacense Sr. Vice President, Licensing.

He confirmed that substantial discounts are offered to first movers while subsequent licensees in the same industry category are subject to progressively higher rates.

The increased momentum of our patent portfolio license signings near the end of 2006 leads us to enthusiastically look forward to further licensing successes by the Alliacense team in 2007.

The MMP Portfolio patents, filed in the 1980s, cover techniques that enable higher performance and lower cost designs, and are fundamental to consumer and commercial digital systems ranging from DVD players, cell phones and portable music players to communications infrastructure, medical equipment, and automobiles, which today have dozens of microprocessor-based key features and benefits.
