Though several states have legalized marijuana use, the drug remains illegal under federal law. Not surprisingly, the United States Patent and Trademark Office (USPTO) refuses to register trademarks related to marijuana because of the federal prohibition.

Specifically, the article argues that the evolving regulatory landscape for CBD and marijuana products has been and continues to be ripe for legal strategists and innovative entrepreneurs to combine forces to create competitive advantage in the emerging marijuana industry.
