"We are excited to announce another major mobile handset manufacturer has joined the MMP Licensing Program,” said Roy Maharaj, Vice President, Licensing for Alliacense.

The sweeping scope of applications using MMP Portfolio design techniques continues to encourage the world’s leading manufacturers of end user products from around the globe to become MMP Portfolio licensees. Over 40 global companies from the US, Europe, Japan, Korea and Taiwan have purchased MMP Portfolio licenses, including many industry leaders such as Fujitsu, Hewlett Packard, Kenwood, Mattel, Nokia, Philips, and Sony.
