General Motors has renewed its patent for the name “FNR” with the United States Patent and Trademark Office, suggesting that neither the General nor Chevrolet — the brand that used the name on a pair of concept vehicles — are done using the moniker. There’s no word yet on when Chevrolet plans to use the name again, but given its history, it could be used on a new concept that will debut somewhere down the road. The USPTO has yet to grant the patent renewal to GM, though it could only be a matter of time before it does.
