Loose-Wiles never registered their "Sunshine" brand name and therefore spent much effort in the first forty years trying to dissuade other companies from using the word "sunshine" or any related word on their product or in their advertising. Since Loose-Wiles claim was not based on a registered mark, they often had to investigate when and where the other company first used the word to determine which company had first claim so as not to lose their right to the name "Sunshine" for their own products. Finally in 1946, the Loose-Wiles Company officially changed its name to Sunshine Biscuit, Inc.
