ShoreTel announced that it has filed counterclaims against Mitel Networks Corp. in response to Mitel's patent infringement lawsuit against ShoreTel.
In addition to denying all of Mitel's claims of patent infringement, ShoreTel alleges that Mitel's IP phone systems, including the Mitel 3300 IP Communications Platform, infringes ShoreTel's U.S. Patent No. 7,167,486 B2 entitled "Voice Traffic Through a Firewall." ShoreTel also filed claims for approximately $10 million in damages and an injunction against Mitel in Ontario Superior Court for making false or misleading statements about ShoreTel's alleged infringement, which were made on the eve of ShoreTel's initial public offering.
