I've fought court battles over my inventions before.

One of the most fun inventions of my lifetime is the Mini.

As an engineer I'm constantly spotting problems and plotting how to solve them.

I want entrepreneurs to be engineers and scientists and designers; they don't necessarily have to be Internet entrepreneurs or retail entrepreneurs.

You need a stubborn belief in an idea in order to see it realised.

Business is constantly changing, constantly evolving.

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.
