From Descriptive to Distinctive: How a Weak Mark Acquires Secondary Meaning
By Casey Scott McKay ·
A descriptive mark is not registrable on the Principal Register and not enforceable in court unless consumers have come to treat it as a brand name rather than a description, a state of affairs the law calls acquired distinctiveness or secondary meaning. This article explains what secondary meaning is under the Inwood primary-significance test, who carries the burden of proving it and to what standard, why the evidentiary bar rises with every degree of descriptiveness, and how the operative language of Section 2(f) of the Lanham Act works, including the exclusions that no amount of evidence can ever cure. It tells the Zatarains and Converse stories in full and sets the Converse six-factor test against the competing factor lists the regional circuits use. Separate sections address the five-year presumption and why examiners so often decline to apply it, look-for advertising, survey formats and the recognition percentages courts have credited or rejected, and the Supplemental Register as a waystation rather than a consolation prize. The article closes on what a 2(f) registration is actually worth, the narrow enforcement scope it buys, the questions that remain genuinely unsettled, and what an experienced practitioner would do.

Summary. A descriptive mark is dead on arrival at the USPTO and in federal court unless consumers have stopped hearing it as a description and started hearing it as a brand. That transformation is called acquired distinctiveness, or secondary meaning, and it is the single most consequential evidentiary problem in trademark prosecution. This article covers what secondary meaning means under the Inwood primary-significance test, who must prove it and when, the operative text of Section 2(f) and the refusals it cannot cure, the five-year presumption and why examiners so often refuse to apply it, the Converse six-factor test and the competing circuit formulations, look-for advertising, survey percentages, the Supplemental Register as a waystation, and the price a 2(f) claim exacts on enforcement scope. It ends where honest doctrine ends: with the questions courts have not answered.
