State route M-22 leads through picturesque Leelanau County, and was the inspiration for brothers Matt and Keegan Myers when they created their company, which bears the sign as its logo. But now the use of that logo is the reason they are facing a lawsuit from the state of Michigan.

When the pair began their company, they filed for - and were granted - a trademark on the sign as the logo for M-22 LLC. The state had five years to contest its use, but did not do so until six years after the trademark was granted.

“The brand had been out there all over the place,” Matt Myers tells Traverse City's Fox 17. “So they had all the time in the world to say something.”

Although the brothers say they've done everything by the book, the Michigan Attorney General's office say their use of a traffic sign violates state and federal law. This week, the state of Michigan filed a lawsuit against the brothers and their company.

The Myers brothers say Attorney Bill Schuette's decision jeopardizes a business they've spent more than $1 million building, and they promise to "go down fighting."
