Here is a sentence that ruins a lot of founders' weeks: owning a logo file is not the same as owning a logo. You can have paid for the design, hold the vector, print it on everything you own, and still discover that legally, the mark was never yours to defend. Trademark law does not care what is in your Dropbox.
What a trademark actually protects
A trademark protects the association between a mark and a source of goods or services, in the categories where you actually operate. It is not a reward for creativity. It is a consumer-protection mechanism that happens to benefit you: the law wants buyers to know who they are buying from. That framing explains everything else. Marks that clearly identify a source get protection. Marks that merely describe a product mostly do not.
The strength ladder
Trademark lawyers sort names and marks on a spectrum, and where you sit determines how defensible you are:
- Fanciful: invented words like Kodak. Strongest protection.
- Arbitrary: real words with no connection to the product, like Apple for computers. Nearly as strong.
- Suggestive: hints at the product without naming it, like Netflix. Solid.
- Descriptive: says what the product is, like Best Coffee Shop. Weak, protectable only after years of proven recognition.
- Generic: the product's own name. Unprotectable, forever.
Notice the pattern: the qualities that make a name easy to defend are the same ones that make it distinctive to a human. The law and memorability point in the same direction, which is convenient.
Before you fall in love, search
The order of operations matters. Search first, then commit. A proper clearance search covers the federal register, state registrations, and common-law uses that never registered at all, because in the US, use in commerce can create rights without any filing. The heartbreaking version of this story is the startup that builds two years of equity in a name, receives a cease and desist, and rebrands at gunpoint. The search would have cost a few hundred dollars. The forced rebrand costs the brand itself.
Registration is cheap. Rebranding under legal pressure is the most expensive design project that exists.
One more unglamorous truth: trademarks are use-it-or-lose-it and category-specific. Register in the classes you trade in, actually use the mark, and keep dates and specimens. Rights you cannot document are rights you mostly do not have.
