Ethicon has more robotic surgery patents than anyone other than Intuitive. They have been hiring robotic engineers for a long time. They could have a way to go in development. Probably not full blown. SPORT is single port and possibly a flat out better performer than our competitors. That's why I think we will attractive to Ethicon and any other company in the space. BTW you said your contact at Ethicon said they will be unveiling a robot soon.
