InterDigital Does Patent Deals

LONDON -- InterDigital Communications Corporation, a leading architect, designer and provider of wireless technology and product platforms, today announced that its subsidiary, InterDigital Technology Corporation (ITC), has signed a non-exclusive, worldwide, royalty-bearing patent license agreement with Research In Motion Limited (RIM), a globally recognized and leading designer, manufacturer and marketer of innovative wireless solutions, including the BlackBerry® Wireless Handheld(TM), for the worldwide mobile communications market.

The agreement covers wireless terminal units built to GSM/GPRS/EDGE standards. Under this agreement, ITC will receive a royalty on each licensed product sold by RIM worldwide. RIM also will make an advance royalty payment to ITC, and once that advance payment is exhausted, RIM will be obligated to pay additional royalties to ITC on each licensed product sold.

Howard Goldberg, President and Chief Executive Officer of InterDigital, commented, "The signing of a worldwide, royalty-bearing license agreement with RIM, a recognized leader and innovator in the wireless handheld device market, is an important step forward as we broaden our reach in the global wireless communications market and diversify our revenue streams."

"The signing of this agreement with RIM reflects the applicability of our technology across multiple wireless devices ranging from mobile handsets to wireless-enabled devices," said William Merritt, President of ITC. "Our success in licensing our patented inventions across a broad range of mobile wireless products and manufacturers affirms the essentiality of our patents, and the competitive importance of our technology for the mobile wireless market."

In a separate release:

InterDigital Communications Corporation (Nasdaq: IDCC), a leading architect, designer and provider of wireless technology and product platforms, today announced that its subsidiary, InterDigital Technology Corporation (ITC), has extended its 1998 non-exclusive, worldwide, royalty-bearing patent license agreement with Sharp Corporation of Japan (Sharp) covering sales of terminal devices compliant with TDMA-based PDC and PHS standards.

Under the extension, Sharp will make a multi-million dollar up-front payment to ITC, including an advance royalty payment. ITC will receive royalties on each PHS and PDC terminal unit product sold by Sharp worldwide at updated rates that recognize the significant increase in volumes and market position that Sharp has attained since the inception of the agreement. Once the advance royalty payment is exhausted, Sharp will be obligated to make additional royalty payments to ITC on sales of licensed products sold through early 2008. The advance royalty payment will be recognized as revenue as it is exhausted through the reported sale of licensed products. The remaining portion of the up-front payment will be amortized on a straight-line basis over the five-year term of the extension.

Howard Goldberg, President and Chief Executive Officer of InterDigital, commented, "The extension of this license agreement with Sharp reflects our strength in maintaining positive business relationships with our licensees. Sharp is an important licensee and a key contributor to our recurring royalty revenues and cash flow. We're pleased that their global market share of mobile wireless products has grown impressively in line with the increasing strength and attractiveness of Sharp's product offerings."

"Our momentum in global patent licensing continues to accelerate," said William Merritt, President of ITC. "We remain focused on expanding existing licensee relationships, strengthening our patent portfolio, and adding new 2G and 3G licensees. Our core competency in this area has enabled us to establish license agreements covering over 70% of the global second generation GSM/TDMA handset market and provided early momentum in the 3G infrastructure and terminal unit markets."

Sharp also is licensed by ITC under a separate, worldwide, royalty-bearing patent license agreement that covers handsets, modules, and communications cards built to 2G/2.5G GSM/GPRS, 2G IS-95 (including the cdmaOne and HDR technology specifications) and 3G CDMA standards, including CDMA2000 and UMTS WCDMA.
