There are two different entities with very similar names and they make it confusing as all get out...
There's Nanotech Industries, Inc. which holds the patents and is a separate private company with the same management.
Then there's Nanotech Industries International which is a wholly owned subsidiary of HCTI and is DBA Hybrid Coating Technologies. They hold no patents. HCTI licenses the exclusive production rights from Nanotech Industries, Inc
