In Horizon 2020, third parties do not sign the grant agreement and consequently are not project beneficiaries – for this reason, they do not have any “automatic” rights to the results under the grant agreement, according to which results are owned by the beneficiary generating them.
As a general rule under the Grant Agreement (Article 30.1 of the Model Grant Agreement), each beneficiary may transfer the ownership of its own results. When doing so, the transferor has in principle the obligation to give at least a 45-day prior notice to the other beneficiaries which still have, or may still request, access rights to these results. The advance notice must contain sufficient information in order for these beneficiaries to identify the transferee and assess whether their access rights might be affected by the transfer.
In Horizon 2020, the general principle is that each partner has the right to transfer its own project results to a third party, such as its mother company.
In Horizon 2020, the main rules applicable to the ownership of project results can be found in the model grant agreement. According to these rules, project results are owned by the beneficiary which generates them. Your organisation would therefore own the results which it has generated.
