Patentleft is the practice of licensing patents (especially biological patents) for royalty-free use, on the condition that adopters license related improvements they develop under the same terms. Copyleft-style licensors seek "continuous growth of a universally accessible technology commons" from which they, and others, will benefit.[1][2]
Patentleft is analogous to copyleft, a licensing mechanism that allows distribution of a copyrighted work and derived works, but only under the same or equivalent terms.
Uses
[edit]The Biological Innovation for Open Society (BiOS) project implemented a patentleft system to encourage re-contribution and collaborative innovation of their technology. BiOS holds patented technology for transferring genes in plants, and licenses the technology under the terms that, if a license holder improves the gene transfer tool and patents the improvement, then their improvement must be made available to all the other license holders.[3]
The open patent idea is designed to be practiced by consortia of research-oriented companies[4] and increasingly by standards bodies. These also commonly use open trademark methods to ensure some compliance with a suite of compatibility tests, e.g. Java, X/Open both of which forbid the use of the mark by the non-compliant.[citation needed]
On October 12, 2001, the Free Software Foundation and Finite State Machine Labs Inc. (FSMLabs) announced a GPL-compliant open-patent license for FSMLabs' software patent, US 5995745. Titled the Open RTLinux patent license Version 2, it provides for usage of this patent in accordance with the GPL.[5]
