Kellogg Co. v. National Biscuit Co.

Kellogg Co. v. National Biscuit Co. (1938) was a legal case involving trademarks and unfair competition. National Biscuit, the maker of Oreo cookies, sued Kellogg for using a similar design for its Marshmallow Krunch cereal, claiming it caused market confusion. The court ruled in favor of Kellogg, emphasizing that the design wasn't distinctive enough to warrant protection and that both companies aimed for different product markets. This case highlights important principles of trademark law, particularly the balance between protecting brand identity and allowing competition in the food industry.
