1. Dumby Enterprises is a conglomerate that has operated a cell phone company, an automobile manufacturing company, and a real estate investment company, all under the Dumby name for over 15 years. Although it is a large and diversified company, the Dumby brand is not recognized as a famous mark. It was about to enter food production, when it learned that a small Texas company has been selling Dumby Bread products through the southern United States for the last 10 years. However, the Texas company has not registered its Dumby Bread trademark. Could Dumby Enterprises successfully sue the creators of Dumby Bread for trademark infringement on grounds of likelihood of confusion? Why or why not?
