Article 27
Access rights for use 1. Participants in the same indirect action shall enjoy access rights to the knowledge arising from work carried out under the indirect action and to the pre-existing know-how, if that knowledge or pre-existing know-how is needed to use their own knowledge. Access rights to knowledge shall be granted on a royalty-free basis, unless otherwise agreed, before signature of the contract. Access rights to pre-existing know-how shall be granted under fair and non-discriminatory conditions. 2. Subject to the participants' legitimate interests, access rights may be requested under the conditions laid down in paragraph 1 until two years after the end of the indirect action or after the termination of the participation of a participant, whichever falls earlier, unless there is provision for a longer period.
