'''OpenType''' is a format for scalable [[computer font]]s. Derived from [[TrueType]], it retains TrueType's basic structure but adds many intricate data structures for describing [[typography|typographic]] behavior. OpenType is a registered trademark of [[Microsoft Corporation]].<ref>{{cite web|title=US Registered Trademark Number 2217574|url=http://htsdr.uspto.gov/#caseNumber=2217574&caseType=US_REGISTRATION_NO&searchType=statusSearch|website=uspto.gov|access-date=September 30, 2014|date=January 12, 1999}}{{dead link| date= November 2016}}</ref><ref name="OFF-chiariglione" />

The specification germinated at Microsoft, with [[Adobe Inc.|Adobe Systems]] also contributing by the time of the public announcement in 1996.

Because of wide availability and typographic flexibility, including provisions for handling the diverse behaviors of all the world's [[writing system]]s, OpenType fonts are used commonly on major computer platforms.
