On April 1, the U.S. patent office announced a new trademark: "Processed plant matter for medicinal purposes, namely medical marijuana." The category was killed three months later when the Wall Street Journal asked about it, but in the meantime ganjapreneurs nationwide filed some very interesting pot trademarks -- with some of the most colorful coming from Colorado.

At least 20 of the 151 or so applications filed for the new trademark came from Colorado -- and there are likely more, filed by trademark lawyers and experts in other states working on behalf of Colorado entities.
