Our success and future growth will depend on our ability to protect our intellectual property. We rely primarily on patent, copyright, trademark and trade secret laws, contractual provisions, and licenses to protect our intellectual property. We also attempt to protect our trade secrets and other proprietary information through agreements with our customers, suppliers, employees and consultants, and through other security measures.

As of January 31, 2006 we held 20 issued U.S. patents and have 23 additional U.S. patent applications pending. Our patents and patent applications cover features, arts, and methodology employed in each of our existing product families. The expiration dates are generally 2019 and beyond. We continue to actively pursue the filing of additional patent applications.

We claim copyright protection for the proprietary documentation used in our products and for the firmware and software components of our products. We have registered "SmartLeap," "CleverConnect," "Fusiv," "Eagle," "Ikanos Communications & Designs" and the "Ikanos Communications" name and logo as trademarks in the United States.
