This information is accessible in the CEN-CLC Guide 8 “Standardisation and intellectual property rights (IPR)” (pdf format) and in the Declaration Form “Statement and Licensing Declaration for CEN and CENELEC Deliverable” (Word Format).
Any person, company or organisation that holds one or more patents (either granted or pending), the use of which may be needed to implement a standard, is strongly encouraged to declare their patent(s) using the CEN-CENELEC Declaration Form “Statement and Licensing Declaration for CEN and CENELEC Deliverable”.
The Declaration Form can also be found in Annex 2 of Guide 8 “Standardisation and intellectual property rights (IPR)” (pdf format)
Completed Declaration Forms must be sent to the attention of the Technical Directors of CEN and/or CENELEC.
By completing and submitting the Declaration Form, patent holders can declare their willingness (or unwillingness) to license the Patents they hold, and specify the conditions under which they are ready to license the use of their patented technologies.
For further information, the CEN-CENELEC Guide 8 also describes the requirements and procedure that has to be followed for the declaration of patents and on the general conditions for licensing patents, which are based on Fair, Reasonable and non-Discriminatory (FRAND) conditions.
The procedure of patent declaration under Guide 8 is largely based on the policy developed at international level by ISO, IEC and ITU.
