Re: If they do not, then they are negligent
Written like a patent lawyer, or someone who thinks their ideas are unique and important because they occurred in close physical association with their personal cerumen. The fact is, not chasing down someone-else's delusions of intellectual grandeur on file at the patent office bolsters the legal argument that the solution was obvious. That can then be hauled out when some troll tries to pirate the work based upon the obscure language of a patent.
