It is out of question the importance that intangible assets have acquired during the last decade. The management of such intangible assets is getting more and more the attention of both academics and professionals. It is aimed, through the application of different models and tools, to measure and manage them in order to achieve competitive advantages that will lead to better business sustainability. In this sense, organizations, taking into account both the intra and the inter-organizational level, must be able to seek and find the most efficient ways of integrating their intangible assets within their performance management systems. Up to now, most of the existing scientific works are focused on managing the intangible assets at the intra-organizational context. The key role that collaborative networks has got at the business ecosystem nowadays, and will have in the future, demands to define frameworks that deal with intangible assets management at the inter-enterprise context. This paper describes an approach of how to integrate intangible assets within collaborative networks. It follows a collaborative business processes approach, taking into account both the global ambit of the collaborative network as well as the individual enterprises that comprise the collaborative network ambit. The model includes a simplified and agile intangible assets management model, which might be used as a reference framework for collaborative networks in this field.
