Now that medical marijuana is allowed in Missouri, entrepreneurs may wish to start registering trademarks for marijuana-related businesses to protect the brands they hope to grow. However, profanity is not the only thing prohibited by federal trademark law. "Lawfulness of commerce" is another consideration when considering a mark for federal registration.
Consult legal counsel to make sure; that's what lawyers are for! If services or products are marijuana-adjacent but federally legal, it may be possible to register a trademark with the U.S. Patent and Trademark Office.
For those looking to enter or already involved in the medical marijuana industry, the MoCannBizCon + Expo coming up in March looks like a good opportunity for networking and learning.
