What is ex ante disclosures of licensing terms?

Ex ante disclosure of licensing terms is a mechanism about committing to licensing terms before the protected technology will be selected as part of a standard or in other words a mechanism about submitting anticipated licensing terms for a given standard draft before the contribution is locked-in as a standard. Ex ante disclosure of licensing terms should not be confused with:


  • the disclosure of IPRs, which is the notification to ETSI of essential or potentially essential IPRs, nor with
  • the requested undertaking in writing of an IPR owner that it is prepared to grant licenses on fair, reasonable and non-discriminatory terms and conditions, pursuant to Clause 6.1 of the ETSI IPR Policy.
Both are independent from the ex ante disclosures of licensing terms and are not replaced by the latter.

It is considered that licensing terms from such disclosures may, in some circumstances, improve transparency for individual Members in considering technologies for inclusion in standards.

How is ex ante working in ETSI?

Any public and unilateral ex ante disclosure of licensing terms by licensors of essential IPRs in ETSI is fully voluntary and for the sole purpose of assisting members in making informed (unilateral and independent) decisions in relation to whether solutions best meet the technical objectives.

There is no obligation for any ETSI Member to disclose any licensing terms related to any of its IPRs. The lack of disclosure by a Member of its licensing terms is not creating any implication under the ETSI Directives. Specifically, the requested undertaking in writing of an IPR owner that it is prepared to grant licenses on fair, reasonable and non-discriminatory terms and conditions pursuant to Clause 6.1 of the ETSI IPR Policy is sufficient when selecting technologies for ETSI standards and technical specifications.

Also and in order to avoid a misleading impression no detailed licensing terms are available from ETSI. ETSI is simply acting as a depository, where IPR owners (licensors) can make available information on how and where to access such disclosed licensing terms, and provide links to URLs of IPR owners, which contain the details of licensing terms and conditions, so that information about the availability of licenses can be disseminated to all users of ETSI standards.





ETSI's position as a recognized European standardization body does not exempt it, its members or its activities from the application of competition law. ETSI is an association of public and private companies and recognizes the importance and impact of competition laws. As it is important for ETSI and its members to strictly comply with all laws that relate to the conduct of their activities, ETSI has developed pdfGuidelines for Antitrust Compliance.





The pdfETSI IPR Policy was adopted by the 21st General Assembly on 23 November 1994 and incorporated in the ETSI Directives as Annex 6 to the ETSI Rules of Procedure.


The pdfETSI Guide on IPRs provides explanatory information on how to handle IPR matters in ETSI and does not replace the ETSI IPR Policy which takes precedence in all cases. The ETSI Guide on IPRs has been endorsed by the Board but does not have the same official status as the Statutes, the Rules of Procedure or the Technical Working Procedures.
