The biggest predictor of whether a trademark registers easily and protects you broadly is where the name sits on the distinctiveness spectrum, a five-rung ladder trademark law uses to rank how strong a mark is.
The ladder comes from a 1976 case, Abercrombie & Fitch v. Hunting World, and it has organized the whole subject ever since.
The five rungs, weakest to strongest
- Generic. The common name of the product itself. Bicycle for bicycles. Never registrable, by anyone, ever. You cannot own the word people need in order to ask for the thing.
- Descriptive. Describes a feature, quality or characteristic. Cold and Creamy for ice cream. Refused unless you prove the public has come to treat it as a brand, which normally means years of use and real evidence.
- Suggestive. Hints at something about the product but requires a mental step to get there. Netflix. Coppertone. Registrable immediately, and the sweet spot for most new businesses: evocative and still protectable.
- Arbitrary. A real word with no connection to the product. Apple for computers. Very strong.
- Fanciful. An invented word. Kodak, Xerox, Verizon. Strongest of all, because nobody else has any reason to use it.
The rung depends on the goods, not the word
This part is often missed. A mark is not descriptive or arbitrary in the abstract. It is descriptive or arbitrary for the goods it is used on.
APPLE is arbitrary for computers and generic for fruit. SUMMIT is suggestive for backpacks and descriptive for a conference centre on a mountain. So the question to ask is never how common or clever the word is. It is how far the word sits from the thing you sell.
Where the line actually falls
The only boundary that gets argued much is between descriptive and suggestive, because that is the line between refused and registered. Three things decide it in practice.
The imagination test. Does a buyer need a mental step to get from the word to the product? If the word tells you the answer immediately, it is descriptive. If it makes you work, even slightly, it is suggestive.
Competitor need. Would honest competitors need this word to describe their own goods? The more they would, the more descriptive it is, because trademark law will not hand one business a word the others cannot do without.
Existing use. If the term already appears across the industry in ordinary descriptive writing, that is evidence it is descriptive, and examiners use exactly that evidence.
What each rung costs you later
Distinctiveness is not only about getting registered. It sets how much protection you get afterwards.
A strong mark has wide scope: you can stop similar marks on related goods without much difficulty. A weak one has narrow scope, because competitors are entitled to describe their products in ordinary words, and because buyers have learned to distinguish similar weak marks by small differences. Two businesses with descriptive names can sit beside each other indefinitely, each unable to do much about the other. That is the crowded field.
Strength can be lost
The ladder is not fixed. A mark that becomes the ordinary name for the product loses protection entirely, which is what happened to aspirin, escalator, thermos and cellophane. It is the one failure mode caused by success, and it is why brand owners are so insistent that their marks be used as adjectives rather than verbs.
The founder mistake, and the fix
New businesses reach for descriptive names because they explain the product. Fast Computers. Best Coffee. Quick Loans. It feels like good marketing and it is the weakest legal position available: hard to register, nearly impossible to enforce.
A name that means nothing on its own usually protects you better than one that describes the product. Choose a suggestive name or something stronger and you get a mark you can enforce. The marketing job of explaining what you do belongs to the tagline, the page, and the product, none of which you have to defend in front of an examiner.
