As for having a better technology, Teewinot's process is synthetic. It involves chemical catalysts which can result in introduction of unwanted impurities and requires separate patents and processes for each of the 90+ synthetic compounds. It's a biocatalytic not purely biosynthetic process.
On the other hand, mCig claims to use genetically re-engineered bacteria. Once these bacteria are created they can presumably be reproduced and distributed with a royalty agreement or license.
