Green Patent License
A Green Patent License is a parallel to a Green Documentation License and Green Software License. This might be an aspect of the Consumerium License if there is a way to require improvements that might be subject to patent into a friendly license so they can't be used to suppress the Consumerium Services.
Alternatively all patentable aspects of extensions could be revealed to the public domain (improvements on which would then be subject to independent patent - self-interested fork) or open patents could be used. However the latter is not self-funding and seems not to really be going anywhere.
