Question: How long does patent protection last? (As of year 2005)

Answer: Utility and plant patents are granted for a term which begins with the date of the grant and usually ends 20 years from the date the applications were filed. You must make the timely payment of the appropriate maintenance fees.

Design patents last 14 years from the date you are granted the patent. No maintenance fees are required for design patents.
