Patent Term Calculator Compliments of the USPTO |
 The
United States Patent and Trademark Office does not calculate expiration
dates for patents. In response to patent owner and public inquiry,
the USPTO is providing a downloadable
patent term calculator in Excel format as a resource to help the
public estimate the expiration date of a patent. The calculator can
be used to estimate the expiration dates of utility, plant, or design
patents. The calculator contains prompts to enter specific information
related to the patent in order to help in estimating expiration dates.
