- The plaintiff, Colgate Palmolive, sued the defendant, Mr. Patel, for infringing on their trademark and trade dress through the similar packaging of Patel's dental products. While the court acknowledged Colgate's trademark on the word used, it ruled that red and white colors were commonly used in toothpaste packaging and could not be monopolized. However, Patel was found to be trying to benefit from Colgate's brand recognition and was ordered to modify the packaging to avoid confusion.
