Intellectual Property


Ideas and innovation are the creative potential of a successful business. This intellectual potential becomes a measurable enterprise value when expressed in property rights (e.g. patents, utility patents and copyright) or monetised through licences. Legally watertight advertising campaigns, press materials that are beyond reproach and careful media usage also make a quantifiable contribution to business success.
