You’re not alone in your concerns. Most companies and research organizations want to protect their IP. A consortium must sign a partnership agreement defining IP rights. This agreement is negotiable among partners and can be reviewed in a standard template. If your proposal is funded, it is advisable to consult a lawyer to ensure IP protection within the consortium agreement.
Your IP will be protected by your consortium agreement, a legal document signed by all consortium members that outlines the responsibilities and privileges of each member, including IP management. The grant agreement with the EU, signed by the consortium coordinator, is separate from the consortium agreement. The EU does not claim ownership of the IP; it remains with the project members.
