Whose Brand Is It? Founder, Partner, and Co-Owner Trademark Disputes
By Casey Scott McKay ·
When a business breaks up, the brand is usually the most valuable thing nobody documented. This article explains how American law decides who owns a mark when two or more people claim it - not by who thought of it, who paid for the logo, or who filed the application, but by who controlled the nature and quality of the goods or services the public associated with it. It works through the factors courts actually apply, the band-name cases that produced the clearest statements of the test, and the reason an application filed by the wrong party can be void from the beginning rather than merely transferable. It covers the departing founder who wants to use their own name, joint ownership and why it is almost always a mistake, and the separation terms that let two businesses coexist without litigating.
