Molecule - a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
Licensing - a permit from an authority to own or use something, do a particular thing, or carry on a trade.
Cognitive Dissonance - a discomfort caused by holding conflicting ideas simultaneously - like licensing molecules.
This isn't a patentability debate it's just plain old cognitive dissonance on the headline.
(Reata Pharma has interesting patents with tons of non-patent prior art and lots of drawings of molecules. - It's probably easier to just license them than to try to read the patents.)
