Also, patent claims are, as far as I can tell, nearly indecipherable. I worked on an application for an invention with really helpful, smart, technically literate lawyers, but after it was all put in the form of claims and figures and embodiments and specifications that could be (but are not necessarily?) implemented in digital electronic circuitry, I could barely it -- and it was my own work! Pity the patent examiners who have to make heads or tails of these things!
