Today’s companies are dependent on intangible assets consisting of informations, knowledge, innovations and creativity which are the main resources of the digital economy. To emerge and survive in the global market, in the digital age, today’s companies must own performances which will outshine the competition and achieve economic progress. These performances are reflected in the intellectual capital that is in the minds of the human resources of the company, their mutual relations as well as relations with external stakeholders. Intellectual capital is one of the crucial concepts in creating competitive advantage in the digital economy. The aim of this paper is to point out the hidden value of intellectual capital, which for decades matures in silence, waiting for the right moment to “explode”. The knowledge that the company owns, as well as the way in which it applies, today is a decisive factor for achieving the optimal development potential of the digital economy and to create a stabile social system. Presenting the different methods of measurement scientists enabled realization of ownership rights and meausuring intellectual capital of the company. Protection of intellectual capital is essential, because in the digital economy, where almost everything is done electronically, the term “abuse” was given a whole new meaning. Finally, intellectual capital is the ultimatum necessary to achieve market dominance and achieving economic prosperity.
