"Mitel has suffered and will continue to suffer damage," the company's lawyers write. "Mitel is entitled to recover damages adequate to compensate for that infringement in an amount that will be ascertained at trial, but in no event less than a reasonable royalty." We have contacted Mitel and the company is not providing much in the way of comment on the suit, neither to us or to The Next Web, which also reported on it, except to confirm the filing. But we have seen that Mitel is not new to this game.
