Moreover, since our foundation by Gilles Holst in 1914, Innovation is how we create superior value for our publishing papers about new developments in Research customers and for our shareholders. We put people at the has been a means to position ourselves as an important center of everything we do, responding to their aspirations, player in the world of science and technology, and needs and desires. strengthen our reputation in innovation. By doing so, Philips Research is a front-end of innovation organization we are able to provide scientific underpinning for our that is a preferred co-creation partner for the Philips commercial offerings, and at the same time attract talent businesses and selected strategic relations. We work in and potential partners for innovation co-creation. multidisciplinary teams, and we are at the leading edge With this publication, we would like to give some insights of core technologies that extend throughout the entire in the most important and impactful patents and publications product portfolio of Philips, which allows the company to that have been created by Philips Research over the past generate new businesses and real competitive advantage 100 years.
