Open patent
The open patent movement seeks to build a portfolio of patented inventions that can freely be distributed under a copyleft-like license. These works could be used as is, or improved, in which case the patent improvement would have to be re-licensed to the institution that holds the original patent, and from which the original work was licensed.
