Don't worry, that is not really true.

  Nevertheless, from the description you give to a lawyer to the final patent, there is both a notable expansion factor and a large drop in comprehensability. Last time I had to do this, the expansion factor was 10, although I think that's above average.

    If there is a drop in comprehensibility, then you probably need a better patent attorney. Patent applications should be as clear as possible. Regarding expansion, this is sometimes necessary. A good patent lawyer may need to add a lot of material to your description. There are many possible reasons for that: for example, you may be so advanced in your field that things that may seem obvious to you are actually pretty complex and must be described in more detail. Or if you have defined your invention too narrowly, a good patent lawyer will describe your invention in different scopes (both broadly and narrowly) and think of all kinds of different fields and applications for your invention, thus ensuring you get a better value out of your patent.
