A Kitsap County jury ruled that Intuitive Surgical was not negligent in the case of a Bremerton man who died after robotic surgery.
Fred Taylor's widow, Josette, sued the makers of a widely used robot after her husband's prostate surgery failed in 2008.
Many doctors use robots in delicate surgeries because they are less invasive and can mean faster recovery.
Fred Taylor agreed to the robotic surgery, but was left with memory loss, incontinence, a torn rectum, kidney and lung damage, and a stroke at the age of 67.
He lived four more years.
Josette Taylor sued Intuitive Surgical, makers of the Da Vinci robot, alleging they misled Taylor's doctor into thinking using the robot was so easy he only needed one day of training at the company's headquarters and two supervised operations before going it alone on Fred Taylor.
Intuitive's attorneys blamed Taylor s doctor, claiming he was told not to use the robot on obese patients like Taylor for his first unsupervised surgeries.
The company also said that the traumatic injuries occurred after the robot was turned off and the doctor had switched back to traditional surgical methods.
The doctor and hospital have already settled in the case.
