Enterasys Networks is suing switch vendors rivals Extreme Networks and Foundry Networks for patent infringement. The complaint, filed in the United States District Court for the District of Massachusetts, alleges that Extreme and Foundry have been and are infringing six Enterasys patents by making and selling networking products that utilise patented Enterasys technology. The patents at issue in the case relate to virtual local area networking, multiprotocol routing and several other networking technologies. “Enterasys has the leading secure data networking product and solution portfolio, and we continue to invest in innovative new technologies and solutions to expand our offerings,” says Gerry Haines, executive vice president of strategic affairs. “Our determination to protect our innovations, and to benefit from the significant value we have created in the form of our intellectual property, reflects our commitment to our customers, partners, and our shareholders,” he adds. Foundry and Extreme accounted for 2.9% and 2.7% of the US$13.9 billion worldwide Layer 2-7 Ethernet switch market in 2004, while Enterasys’ share of the market was 1.6%, according to research firm In-Stat. Cisco was the market leader with 68.6% of all switch revenue.
