According to the USPTO there are mainly six types of patents namely:

Utility Patent  Issued for the invention of a new and  useful process, machine, manufacture, or composition of  matter, or a new and useful improvement thereof, it  generally permits its owner to exclude others from making, using, or selling the invention for a period of up to twenty years from the date of patent application  filing , subject to the payment of maintenance fees. Approximately 90% of the patent documents issued by the PTO in recent years have been utility patents, also referred to as “patents for invention.”

Design Patent-  Issued for a new, original, and ornamental design for an article of manufacture, it permits its owner to exclude others from making, using,  or selling the design for a period of fourteen years from the date of patent grant.  Design patents are not subject to the payment of maintenance fees

Plant Patent-  Issued for a new and distinct, invented  or discovered asexually reproduced plant including  cultivated sports, mutants, hybrids, and newly found seedlings, other than a tuber propagated plant or a  plant found in an uncultivated state, it permits its   owner to exclude others from making, using, or selling  the plant for a period of up to twenty years from the  date of patent application filing .  Plant patents  are not subject to the payment of maintenance fees.

Reissue Patent-  Issued to correct an error in an already issued utility, design, or plant patent, it does not affect the period of protection offered by the  original patent.

Defensive Publication (DEF)-  Issued instead of a  regular utility, design, or plant patent, it offers  limited protection, defensive in nature, to prevent  others from patenting an invention, design, or plant. The Defensive Publication was replaced by the Statutory Invention Registration in 1985-86.

 

Statutory Invention Registration (SIR)-  This document  replaced the Defensive Publication in 1985-86 and  offers similar protection.
