There are essentially three types of patents: Utility, Design and Plant.
- A Utility Patent is “issued for the invention of a new and useful process, machine, manufacture, or composition of matter, or a new and useful improvement thereof.” If granted, its owner may exclude others from making, using, or selling the invention for a period of up to twenty years from the date of filing the patent application. For a Utility Patent to remain in force the owner must make periodic maintenance fee payments. Approximately 90% of patents issued are Utility Patents. This type of patent may also be called “patents for invention.”
- A Design Patent is “issued for a new, original, and ornamental design for an article of manufacture.” The period of protection for a Design Patent is fourteen years during which its owner may exclude others from making, using or selling the design. Maintenance fees are not required for Design Patents.
- A Plant Patent is “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.” A Plant Patent owner may exclude others from making, using, or selling the plant for a period of up to twenty years from the date of filing the patent application filing. Plant Patents are also not subject to the payment of maintenance fees.
