The 13 winners were responsible for about 600 inventions made in 2004, accounting for approximately 7.5% of all reported inventions in the same year. The SIEMENS Inventor’s Award is aimed at enhancing inventive and innovative activities of the roughly 50,000 employees in the field of R&D. In 2004, SIEMENS spent 5.1 billion Euros in R&D (accounting for 6.8% of sales), resulting in 23.2 million Euros per working day.
