What could be the motives of such a patent claim? The old legal wisdom stands even in our times: "Dolo petit quid rediturum est". Could it be lack of dilligence? Could it be misled judgement of prior art? Of course nobody would propose sinister motives like "Find enough idiots who pay up and run" since that for sure would lead to a defamation suit, a popular past time in our part of the world. So we keep wondering what this is all about!
