"That being said, perhaps the most troubling finding in our security analysis is that Intel included a licensing mechanism in SGX that prevents software developers who cannot or will not enter a (yet unspecified) busi- ness agreement with Intel from authoring software that takes advantage of SGX’s protections.

Only these patents disclose the existence of licensing plans."
