Who owns the phrase "Taco Tuesday?"

You may have seen the recent TV commercials for Taco Bell, in which NBA superstar LeBron James argues that no one does - that it's a phrase so commonly used that the U.S. government should eliminate the trademarks held by two companies who currently own the rights to the phrase.

Taco Bell has also filed legal petitions with the United States Patent and Trademark Office to cancel the trademark held by two U.S. companies - including a family-run restaurant in Somers Point, New Jersey.

It's a strange turn of events for the owners of Gregory's Restaurant, which started a Taco Tuesday special in 1979 and was issued a trademark for the phrase in 1982.

On today's "Brian's Positively New Jersey,” Brian Donohue travels to Somers Point where Taco Tuesday is a 44-year-old tradition that is now the target of a legal battle and a superstar's ad campaign.
