NCAA filed complaint against urologists that "Vasectomy Mayhem" marketing schtick is too close to "March Madness" trademark

The National Collegiate Athletic Association (NCAA) filed a complaint with the US Patent and Trademark Office, arguing that the Virginia Urology clinic's use of the slogan "Vasectomy Mayhem" in a marketing campaign conflicts with their trademark of "March Madness." From NBC News:

Virginia Urology's use of "Vasectomy Mayhem" will "result in confusion, mistake or deception with petitioner and/or the goods and services marketed in connection with the NCAA," according to Chicago-based lawyer Douglas Masters, representing the NCAA[…]

The NCAA cited various ads Virginia Urology has run, including one with the words "Hoops Madness" that has twin basketballs used for the double-o in "hoops."
