Reminder on Design v. Utility Patents

by Steve Reiss - now at

Just a reminder on US patent terms --

Utility patent terms are 20 years from the earliest priority date. Maintenance fees are due at 3½, 7½ and 11½ years after grant of the patent.

Design patent terms are 15 years from grant. Design patents do not have maintenance fees.
