In my past experience, this is only true because many people's eyes glaze over when they try to read patent-ese. If you can penetrate the obtuse form of English used, "in embodiments, ... may be ... to name a few" for example (and the weird ordering of paragraphs, etc.), it's actually not that hard to understand patents. There are a lot of people whose job it is to read patents, too.
