Corporate mergers are becoming increasingly common due to rising competitive pressure and globalization, and in our fast-paced world, they represent one of the few opportunities to acquire strategic intangible assets. However, the focus in acquisitions often leans too heavily on financial aspects, neglecting the truly valuable resource: knowledge. Today, knowledge is the trump card in competition, and there is a growing trend towards the immaterialization of value chains. Therefore, I aim to address these developments and conceptualize the management of the valuable and scarce resource of knowledge within the merger process. The case study examines the acquisition of Improx AG by the ISIS Papyrus Group from 2001 to the present, viewed through the lens of knowledge management, involving two companies from the highly knowledge-intensive software industry.
