Belize - excellent post, however I have to go against the grain on (4). "Frivilous" is the term used by the company subject to the lawsuit, therefore all lawsuits are considered frivilous, by one of the two parties involved. In general, patent suits are common place amongst medical device manufacturers - BSX v MDT, Neurovision v Nuvasive, Mako v Bluebelt Technologies, KCI v SN, Computer Motion v ISRG and Neutar v Mazor Robotics, to name a few. Now, I am hopeful that if a patent suit is initiated - it's on Titan's end, like previously stated and I am cautiously optimistic Titan/Columbia's patent attorney's have done the exhaustive research necessary to protect their IP. Frivilous or not, it would be naive to believe Intuitive will sit back idle and allow Titan to flawlessly execute their strategy without trying to disrupt/crush them. I do hope I am wrong...
