Plougmann Vingtoft was founded in 1967 by Knud Erik Vingtoft and Ole Plougmann. 

Mr Plougmann was a chemical engineer with plans to revolutionise the patent world; Mr Vingtoft was a mechanical engineer whose attention was caught by the patent industry in 1959. Together they created a firm that has, ever since, influenced the way people approach IP rights. The two engineers’ pioneer work within biotechnology and information technology led to strong IP positions for their clients and made the name, Plougmann Vingtoft, well known in the business.

In addition, the two founders’ interest in the commercialisation of research results made the firm one of the main players in building collaborations between private companies, universities and scientists in Denmark, as well as internationally.
