All kinds of patents expire after 17 years.

  But if I'm not mistaken they can get indefinite patents as well which seems more like abuse than privilege. 17 years as well...seems like to long a time frame to me., but again I'm not expert. I'd have gone 10 years max.

    Is it possible you're thinking about Disney, and their extending copyrights?
