Well, LEGO used to have a factory there. So apparently they did research and development of new products there as well.
From internet: "The Lego Group is a family owned business, and corporate is located in Billund, Denmark. The manufacturing factory was located in Willisau, Switzerland until late 2006, it was then moved to the Czech Republic in Eastern Europe, the move was forced by rising production cost."
Googlemaps says Baar and Willisau are ±60 km away from each other by car so they are more or less in the same region.
