|Clauses in patent licenses|
An essential patent or standard-essential patent is a patent that claims an invention that must be used to comply with a technical standard. Standards organizations, therefore, often require members disclose and grant licenses to their patents and pending patent applications that cover a standard that the organization is developing.
If a standards organization fails to get licenses to all patents that are essential to complying with a standard, owners of the unlicensed patents may demand or sue for royalties from companies that adopt the standard. This happened to the GIF and JPEG standards, for example.
Determining which patents are essential to a particular standard can be complex.
- Patent ambush, a situation where a member of a standards organization withholds information about patents they own during development of a proposed standard and subsequently claims them to be relevant to the standard as adopted.
