I'm not saying that all legal advice is good advice-- that's why there are (occasionally) malpractice suits. Similarly, not every surgery is successful-- but I'll take my chances on a Board Certified Surgeon over a random member of the public, anyday. In this case, the downside of not having proper legal advice is substantial-- being a defendent in a patent infringment can't be much fun-- and the cost should be minimal.
