Secrecy / Confidentiality. 14.1 Each contracting party shall use any documents (including samples, models and data) and knowledge which it obtains from the business relationship only for the jointly pursued purposes and shall keep them secret from third parties with the same care as its own corresponding documents and knowledge if the other contracting party designates them as confidential or has an obvious interest in keeping them secret. This obligation shall commence from the first receipt or knowledge of the documents and shall end 36 months after the end of the business relationship. The obligation shall not apply to documents and knowledge which are generally known or which were already known to the contracting party at the time of receipt without the contracting party being obliged to maintain secrecy, or which are subsequently transmitted by a third party entitled to pass them on or which are developed by the receiving contracting party without exploitation of documents or knowledge of the other contracting party which are to be kept secret.
