9. How long is a patent protected?

The maximum term of a patent is 20 years from the application date. Rights of prohibition against third parties using or imitating the invention may be enforced once the patent is granted. Many patents expire early due to non-payment of annual fees because no opportunity for exploitation arises for the patent holder, who is no longer willing to assume these costs if the patent does not generate revenue.
