Intuitive Surgical Sued Over Heart Stabilizer Patent

Intuitive Surgical’s da Vinci surgical robot infringes at least one claim of a patent owned by Alisanos, according to a lawsuit. Alisanos, a Longview, Texas-based intellectual property development and licensing company, accused Intuitive of learning the ins and outs of its patent for the so-called ’573 patent, or “Through-Port Heart Stabilization System,” when they began negotiation over a possible partnership in November 2000.
