The term of a patent is the maximum period during which it can be maintained in force. It is usually expressed in a number of years either starting from the filing date of the patent application or from the date of grant of the patent. In most patent laws, renewal annuities or maintenance fees have to be regularly paid in order to keep the patent in force. Otherwise the patent lapses before its term.
The term of a patent or specific "claims" in a patent may also be curtailed by judgment of a court, as where a claim or patent is held "invalid" under the relevant law, and thus no longer enforceable.

International harmonization
Significant international harmonization of patent term across national laws was provided in the 1990s by the implementation of the WTO's Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs Agreement). Article 33 of the TRIPs Agreement provides that
- "The term of protection available [for patents] shall not end before the expiration of a period of twenty years counted from the filing date."
Consequently, in most patent laws nowadays, the term of patent is 20 years from the filing date of the application. This however does not forbid the states party to the WTO from providing, in their national law, other type of patent-like rights with shorter terms. Utility models are an example of such rights. Their term is usually 6 or 10 years.

Jurisdiction
Europe
The European Patent Convention requires all jurisdictions to give a European patent a term of 20 years from the actual date of filing an application for a European patent or the actual date of filing an international application under the PCT designating the EPO. The actual date of filing can be up to a year after the earliest priority date. The term of a granted European patent may be extended under national law if national law provides term extension to compensate for pre-marketing regulatory approval. For EEA member states this is by means of a supplementary protection certificate.
United States
In the United States, for utility patents filed on or after June 8, 1995, the term of the patent is 20 years from the earliest filing date of the application on which the patent was granted and any prior U.S. or Patent Cooperation Treaty (PCT) applications from which the patent claims priority. For patents filed prior to June 8, 1995, the term of patent is either 20 years from the earliest filing date as above (excluding provisional applications) or 17 years from the issue date, whichever is longer. Extensions may be had for certain administrative delays.
The patent term will additionally be adjusted to compensate for delays in the issuance of a patent. The reasons for extensions include:
- Delayed response to an application request for patent.
- Exceeding 3 years to consider a patent application.
- Delays due to a secrecy order or appeal.
Because of significant backlog of pending applications at the USPTO, the majority of newly issued patents receive some adjustment that extends the term for a period longer than 20 years.
For design patents (patents based on decorative, non-functional features), for design applications filed on or after May 13, 2015 the term is 15 years from the issue date. For design applications filed before May 13, 2015, the term is 14 years from the issue date.
