For Bo Muller-Moore, a folk artist from Vermont, the T-shirts he hand-screens with the slogan “Eat More Kale” are a dream fulfilled: a quirky project that has emblazoned this leafy mandate across the chests of people worldwide, and one he wants to trademark.

So when Chick-fil-A, the fast-food chain that says it sells 537 sandwiches a minute with the help of the slogan “Eat mor chikin,” sent him a cease-and-desist letter this fall, Mr. Muller-Moore decided to fight the company, setting off a groundswell of local support and national media attention.

“This is corporate bullying,” Mr. Muller-Moore said. His lawyer, Daniel Richardson, sent Chick-fil-A a letter in November, contesting its claim that the slogan “is likely to cause confusion of the public and dilutes the distinctiveness of Chick-fil-A’s intellectual property.”
