You can often dodge patent claims by doing just one little thing in a different way. When you see a very specific claim, it means the patent lawyer was forced to write it that way by the examiner. A patent application starts out as generic as possible and becomes increasingly specific in response to push-back. Of course, non-infringement is no guarantee against getting dragged into a costly legal battle.
