In August 2000, [[Microsoft]], [[Hewlett-Packard]], [[Intel]], and others worked to standardize CLI. By December 2001, it was ratified by the [[Ecma International|Ecma]], with [[International Organization for Standardization|ISO]]/[[International Electrotechnical Commission|IEC]] standardization following in April 2003.

Microsoft and its partners hold patents for CLI. Ecma and ISO/IEC require that all patents essential to implementation be made available under "[[Reasonable and non-discriminatory licensing|reasonable and non-discriminatory (RAND) terms]]." It is common for RAND licensing to require some royalty payment, which could be a cause for concern with [[Mono (software)|Mono]]. As{{as of |2013|January 2013}}, neither Microsoft nor its partners have identified any patents essential to CLI implementations subject to RAND terms.{{cn|date=October 2024}}
