The important thing is to learn from mistakes - something graduates are adept at. Our graduate engineers are working on new technology - from uncharted applications for our digital motor, to a new take on the hand dryer. With an unhindered mind, nothing is off limits.

All our engineers are designers and all our designers are engineers.

If you didn't have patents, no one would bother to spend money on research and development. But with patents, if someone has a good idea and a competitor can't copy it, then that competitor will have to think of their own way of doing it. So then, instead of just one innovator, you have two or three people trying to do something in a new way.
