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 (excluding provisional applications). For patents filed prior to June 8, 1995, the term of patent is either 20 years from the earliest filing date as above 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. 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. ==See also==
