In the biotech space there exists a system called "patentleft" which theoretically provides royalty-free licensing of patents with the stipulation that any derivative works / improvements also be licensed under the same terms.

Seems like there is good potential to build on the momentum of Tesla's announcement to formalize the process, and answer the questions that I'm sure will emerge in this thread - eg more akin to an Creative Commons (which is very well defined and practical).

How common is this - are there any well known examples? (If so, they're not in wikipedia!)

Patentleft is analogous to 'Copyleft' which is a play on words to Copyright.
