The name "ISIS" has been popping up a lot in the news recently.

It's an acronym for the Islamic militant group currently operating in Iraq and Syria, but it's also used in the names of more than 270 product, service and business names, according to the U.S. Patent and Trademark Office.

This has led to a bit of brand confusion among consumers and a headache for business owners with the name. Tom Murphy of the Associated Press recently wrote about this and says some companies are debating whether to change their names, while some already have.
