Edison's light bulbs were also derivative of many other efforts. Being derivative doesn't exclude you from being able to patent something.

- Aloha 10y agoEdisons bulb was actually novel, it was novel because it was a high resistance bulb (others were low resistance, so they consumed huge amounts of power), and it had a long life, hundreds of hours instead of tens of hours.
