Patent pools are agreements between "two or more patent owners to license one or more of their patents to one another or to third parties." [http://www.wipo.int/export/sites/www/ip-competition/en/studies/patent_pools_report.pdf (WIPO)] Generally, patent pools cover mature and complex technologies that require complementary patents to develop compatible products and services. [http://www.wipo.int/export/sites/www/ip-competition/en/studies/patent_pools_report.pdf (WIPO)]. More recently, patent pools have become standardized by the Department of Justice, legally recognized only if the following four criteria are met:

:: # Complementary patents included only.

:: # Sensitive information may not be shared amongst parties.
