AUGUSTA, Maine (AP) Authorities in Maine say businesses, nonprofit groups and government organizations should be wary of a scam about expiring trademarks.

Maine Attorney General Aaron Frey and Secretary of State Shenna Bellows said Friday the scammers fraudulently warn entities that their trademarks are about to expire and request a renewal fee.

The notices from the scammers often resemble a government agency and sometimes even include accurate information about the trademark’s registration number and expiration date.

Frey says Maine residents who are concerned they have have received a fraudulent notice or sent money as a result should contact the Maine Office of the Attorney General.
