[Quoting Abraham Lincoln, who said the patent system] adds fuel interest to the fire of genius, ... the patent system must appropriately reward innovation and risk.

To me, innovations are the wheel, fire, language, movable type. There are not 3 million innovations; there are 3 million inventions.

This Isaac is a genius!

In some cases, inventions prohibit innovation because we're so caught up in playing with the technology, we forget about the fact that it was supposed to be important.

I've never regretted anything I've done, even the things that I've failed at. I've often regretted not trying something really big, because you'll never know.

My biggest worry is I'm running out of time and energy. Thirty years ago I thought 10 years was a really long time.
