Trademarks
The name Whopper is a registered trademark of Burger King Holdings and is displayed with the ®-symbol in all markets it is sold. The name Whopper Jr. is a registered trademark in the US, Canada and Europe.
When Burger King expanded into the San Antonio area, it was prevented from utilizing the name Whopper in its local advertising and stores due to a prior state registered service mark owned by a local chain known as Whopper Burger. The chain, owned by Frank and Barbara Bates, prevented the company from using the name in Bexar County for several years until Mrs. Bates, the CEO of Whopper Burger after the death of her husband in 1983, retired and sold the chain with its related trademarks to then-corporate parent Pillsbury in the mid-1980s.
